3 Project Background

3.1 Project Background

4

The ecological issues become more and more serious due to the wastewater

distributed with high pollutant loads. With the larger scale sea development of the Bohai

Sea, the contradictions between development and environmental protection become more

seriously. Dongying City is the direct suffer from the serious pollution of the Bohai Sea.

Only in 2008, the pollutant distributed by Dongying City to the Bohai Sea contains 2100t

COD, 393t BOD, 368t NH3-N, 85t total phosphorus and 48t total nitrogen. Under this kind

of status, WB and GEF conduct cooperation to improve the ecology system pollution of

the large sea. In order to reduce the pollution to the Bohai Sea, Shandong Province utilizes

the GEF grant and local counterpart fund to manage and control the pollution to the

Guangli River of Dongying City which sets a good example for other river basin pollution

management in Huai River basin.

Guangli River is the main drainage river of the central city in Dongying City, the river

flows from Wangying Sluice of Nanzhan Dam of Yellow River to the central city with a

flow path from west to southeast and then to the Bohai Sea after the combination with

flood controlling rivers, the total length is 60km with a coverage area of 510 km2 which

plays a important role in water supply, drainage, flood control and ecology improvement.

Besides, Guangli River is the main wastewater catchment and nearly 40,000 ton/day of the

wastewater was distributed to this river and its branches in 2009, more than 90% of that is

urban daily life wastewater while the others is industrial wastewater. Due to the weak

sewerage pipeline and the wastewater distributed to the river without treatment, the water

of the Guangli River was seriously polluted. Though several improvement projects were

conducted by Dongying City in recent years, the water quality of Guangli River still can

not meet the Class V requirement.

In order to rehabilitate the ecology system, increase the biodiversity, prevent the water

loss and soil erosion, improve the climate and conserve the water source and improve the

water quality of Guangli River and Bohai Sea, Dongying City proposed to construct this

project supported by WB.

3.2 Project Necessity

�1�Comply With the Development Planning of Effective and Ecological Economic

Region for the Yellow River Delta.

The Yellow River Delta locates in the entrance of the Yellow River which is to the

south of the Bohai Sea and it is an important strategic site for the development of the Bohai

Sea Region. China pays much attention to the sustainable development of the Yellow River

Delta and the requirements listed in the Tenth and Eleventh Five-year Plans require to

5

carry out effective and ecological economy in this region. In order to promote the effective

and ecological development of this region, China has developed and issued The

Development Planning of Effective and Ecological Economic Region for the Yellow River

Delta. It is defined that Strengthen the environmental protection by prevention and

comprehensive improvement, EP standards and pollutant distribution controlling systems

should be implemented strictly to increase the environment carrying capacity. Strengthen

the industrial wastewater treatment; close the enterprises with high pollutant loads;

prevent the industrial pollution diverting to the rural area. Strengthen the rural

environmental protection, focusing on the livestock breeding pollution, soil pollution and

rural solid waste pollution to control the rural pollution source effectively. Strengthen the

pollution improvement to the key river basin and comprehensive improvement to the lesser

river basin.

Guangli River is a key river of Dongying City, but its water quality is far below the

required Class V standard of Surface Water Quality Standard GB3838-2002 . In view

of this issue, this proposed project will construct wetlands in the downstream of the

Guangli River and implement rural pollution improvement in the pilot villages along the

Guangli River which will improve the water pollution in Guangli River and Bohai Sea, so

that complies with the Development Planning of Effective and Ecological Economic

Region for the Yellow River Delta.

�2�Comply with the Planning for the Wetlands Construction of Shandong Province.

The planning defined that scientific waste treatment approaches should be adopted

during the river improvement process, not only focus on the security of the water quality

but also the economic development and social stability. That is to say the project shall

focus on each rivers of the basin and follow an integrate thought of project objectives, total

quantity, project and investment, adopt a strategy of improvement, utilization and

protection, comprehensive utilization of economic, legal and scientific and technology

approaches and make full use of the roles of market mechanism, macro-control mechanism

and public participation mechanism to promote the economy structure adjustment within

the basin, urban infrastructure construction, clean production, pollution improvement and

ecology protection works, then promote the comprehensive pollution improvement works

within the basin.

Wetland is composed of water, matrix under permanent or intermittent saturation,

aquatic life and aquatic plants which is a complex ecology system with high productivity

and great activity. As an important habitat for a variety of livings, it also has the following

6

functions, such as water conservation, flood and water logging control, water purification

and pollutant degradation, etc. Wetland is one of the most productive ecology systems in

the world and it is the cradle for biodiversity and storage place for important genetic

substances. Artificial wetland is designed to simulate the structure and functions of natural

wetlands which is composed of matrix under permanent or intermittent saturation,

emergent plants, submerged plants and animals, utilize appropriate shape, size, water

distribution and collection systems to ensure a good water flow and high pollutant removal

efficiency.

There are a number of successful examples and adequate practice experience in

utilizing wetland to purify the water quality in Shandong Province, such as wetland for

Jining WWTP with a coverage area of 1500 m2 under the joint construction of Shandong

EP Bureau and Jining Municipal Government in 2003; Xinxue River Wetland for Water

Purification Project with a coverage area of 1500 mus under the joint construction of

Shandong EP Bureau, Jining Municipal Government and Weishan County Government in

2005. All of the above wetland projects are operated with a good outcome.

So this proposed project complies with the Planning for the Wetlands Construction of

Shandong Province.

3 Comply with the Planning of Yellow River Water City- Water Pollution

Improvement Project for Dongying City.

It is clearly defined in the Comprehensive Management of Water and Air Pollution

Implementation Scheme for Environmental Protection Plan of Dongying City that the river

basin water pollution prevention and control work shall be strengthened, and one of the

projects is the construction of Dongba Road Wetland Project which is the wetland

construction of this proposed project, so this proposed project complies with the Planning

of Yellow River Water City- Water Pollution Improvement Project for Dongying City.

3.3 Industrial Policy and EP Policy Compliance

4.1 Contents of the Wetland Project

4.1.1 Land Acquisition Status of the Project

The total land acquisition area for the project is 2698.5 mus, including 73.5 mus and

2625 mus for west ecological retention pool and east surface flow wetland respectively.

Only the fish ponds and saline-alkali fields are acquired within the land acquisition area,

and these lands are under a low utilization rate with a low crops production. Since the

project locates in the downstream of the river and the land acquisitions are in line with the

national policies, so the current land status is good for the smoothly implementation of the

wetland project.

4.1.2 Main Contents of the Project Construction

According to the regional hydrogeology, water quality, pollution sources distribution

and land utilization status, and taking the development planning of Dongying City and the

representativeness and promotion of wetland project into consideration, it is selected that

the wetland project will be constructed at Dongba Road in the downstream of Guangli

River.

�1�Process Scheme

The process of ecological retention pool + surface flow wet land is selected for the

water purification project of Dongba Road Wetland. Through the construction of sluice

gate in the north bank of Guangli River, the polluted water will be diverted to the

bottomlands in the wets of Dongba Road and then the bottomlands will be transformed into

ecological retention pool. The polluted waster will be discharged to the surface flow

wetlands in the east of Dongba Road after the preliminary treatment in the retention pool.

The pollutant of the wastewater will be reduced by the metabolic activities of

microorganisms and aquatic plants existed in the retention pools and surface flow

wetlands. The outflow will meet the Class V standard through the triple synergy of

physical, chemical and biological roles of the wetlands. The outflow will be pumped into

the water systems in Huanghe Road by the new constructed pump station once the outflow

meets the required water quality standards. See Figure 4-3 for the detailed wastewater

treatment process.

�2�Identification of Treatment Capacity

The wetland coverage area is 2698.5 mus. Taking the useful land area of the wetlands

and the water quality characteristics of Guangli River into consideration, the water load is

defined as 4cm/d and 1.5cm/d for summer and winter respectively. So the treatment

capacity of Dongba Road Wetland is as the following:

Q1=7.0×104m3/d �March to November�

Q2=2.5×104m3/d December to February

�3�Identification of the Inflow and Outflow Water Quality

According to the Planning of Yellow River Water City- Water Pollution Improvement

Project and taking the current water quality of Guangli River and the outlet will be

discharged into water systems in Huanghe Road for landscaping into consideration, the

outlet water quality is defined as Class V to meet the requirements of Surface Water

Quality Standard (GB3838-2002). See Table 4-3 for the detail indicators for the water

quality of inflow and outflow.

�4�Ecological Retention Pool

The ecological retention pool will be constructed in the bottomlands with a length of

350m from east to west and a width of 140m from south to north, the retention pool locates

in the west of Dongba Road, north of Guangli River bank and south of Dongxin Oil

16

Company. Base on the site conditions, a sluice gate for wetlands, wet weir and north weir

will be constructed in 300m place to north bank of Guangli River and west of Dongba

Road. The bottom level of the retention pool will be adjusted to plant various kinds of

hydrophytes and the solar aeration machines and floating islands will be set up in the deep

water. The outflow of the retention pool will be discharged into the surface flow wetlands

by the pipelines.

�Weir

The weirs will be constructed in the west and south of the retention pool with a top

width of 5m, height of 2m, slope ratio of 1:3 and a total length of 440m. A 1m tall slope

protection wall will be constructed in the slope against the water which is 0.5m above the

designed water level and the plant the local plants in the slope.

�Aeration Facilities

It is designed that four solar pumping devices will be equipped to exchange the

surface water and the bottom water and to increase the dissolved oxygen of the water, then

increase the pollutant reduction rate.

�Hydrophytes

The lotus and water lily will be planted in the water area with a deepth from 0.6m to

1.5m and hornwort, vallisneria, hydrilla and crispus in the water area with a depth from

1.5m to 2.0m. Different plants will be plant in different area to reduce the pollutant. The

floating island will be construted in the deep water and the different plants will be planted

there, such as canna, loosestrife, bulrush, iris, water chestnut and other plants

�5�Surface Flow Wetland

Different levels of the surface flow wetlands will be constructed within 500m of the

east of the Dongba Road with a length of 3500m from the south of north bank of Guangli

River to the north of bottomlands Huanghe Road, the outflow of the wetlands will be

discharged into the water systems of Huanghe Road by the lifting pump station. The

wetlands system contains section A and section B in a parallel connection way, and there

are three levels of wetlands for each section in a series connection way. The distribution

channel will be constructed in the primary wetland units of section A and section B.

In order to strengthen the wastewater treatment in primary and secondary wetland

units, the earthwork, origin embankment and river bed height are adjusted and the bulrush

and other local wetland plants are planted with a density of 6 to 9 plants/ m2 in the

designed water depth from 0.5m to 0.8m. Potamogeton, crispus and other submerged

17

plants are planted in the deep water with a designed depth from 0.8m to 2.5m, and then the

pollutant will be deep purified in this section.

The deep water section without emergent aquatic plants and section mixed aquatic

plants will be set up in the tertiary wetland to ensure the weland has an open surface of

30%, so that can increase the reoxygenation capacity and landscaping effectiveness of the

wetland system. The floating-leaved plants, submerged plants and some aquatic plants are

planted in this section, such as bulrush and cattail in the left bank, lotus, water lily and

water chestnut will be planted in the shallow area and P.pectinatus Linn and Potamogeton

algae will be planted in the deep water area. Through the optimized combination of the

plants, the wetland can be operated steadily and increase the biodiversity.

Coverage rate of 60-

65% �Sluice Gate

The inlet volume flow into the distribution channel of Section A and B will be

controlled by the sluice gate. At the same time, two sluice gates will be constructed in the

gated overflow weirs to control the water level of the wetlands.

The sluice gate is made of reinforced concrete with two holes, the net width is 1m and

the gate height is 1.5m.

�Distribution Channel

Adopting the overflow weir to distribute the water will ensure the outflow from the

WWTP can flow into the wetlands evenly. Two C30 reinforced concrete distribution

channel will be constructed with a width of 1.5m, height of 1.05m and length of 200m.

�Weir and Partition of Wetlands

18

The main function of the weir is to maintain the water treatment coverage of the

wetland water quality improvement project and to ensure the treatment effectiveness. The

outer weir is constructed in a slope by soil compaction structure, the required earth comes

from the adjustment of the wetland bottom and the slope rate is 1:3 for the outer weir with

a top width of 5.0m and added height is 1.5m to 2m with a total length of 7500m.

�Ecological Slope Protection

The ecological slope locates in the wetlands weir and partition. According to the

status of the channel and partition and the hydraulic conditions, the slope protection

technique and the root stability ecological slope protection technique are adopted to

smooth the natural embankment and protect the natural plants, and then the flood discharge

space will be expanded. The length of the slope is about 8000m with a top width of 3.0m

and has 5333 trees with grass coverage of 96000 m2.

�Gated Overflow Weir

The weir can maintain the wetland in a high water level and collect water evenly. The

gated overflow weirs in section A and B have a same length of 200m, the top width is 2.0m

and the height of the weir is 1.0m with a slope rate of 1:3. The inside of the slope is made

of compacted clay and the outside is constructed in a masonry structure.

6 Sluice Gate and Pump Station

An entrance gate will be constructed in 300m away from the west Dongba Road and

north bank of Guangli River to draw the water of Guangli River to retention pool.

A lifting pump station will be constructed in the outlet of the wetland, then the

outflow of the wetland can be pumped into the watere systems at Huanghe Road and used

for landscaping.

7 Counterpart Facility

A comprehensive administration building will be constructed in the outlet of the

wetland to manage the daily work and disseminate the wetland project to the public. The

building has two floors with a construction coverage area of 480m2 and a parking lot was

constructed with a coverage area of 300m2. A wooden platform was constructed in the

wetland area for birds view with a width of 1.5m and a total length of 1500m.

4.1.3 Sluice Gate Operation Optimization

The pollutant discharging will be reduced through the sluice gate optimization;

through the distribution, diversion, storage of the natural runoff, regulation of the water

level and prevention of encroachment of sea water to ensure the management and

19

utilization of the sluices.

Water Body of Guangli River

Before the water was discharged into the sea, the water will first flow into Dongba

Road Wetland for treatment by No.1 Gate and then flow into the water systems at Huanghe

Road by No.2 Gate, and then flow back to Guangli River.

Other Water Circulations

The hydraulic condition and water self purification ability will be improved by the

periodically water supplement from the upstream (e.g. Wugan Channal) and water

circulation measures. It will also contribute the continous operations of the downstream

wetland.

During the flood period, the wastewater generated after the first flood should not be

concentrative discharged so that can avoid the emergent water pollution for the river

downstream and the entrance to the sea, and can reduce the pollution to the Bohai Sea.

With the regulation and self purification functions of Minghai Sluice Gate and

Minghong Sluice Gate in Guangli River, Minghui Sluice Gate in Gengjing Reservoir,

urban water systems and wetlands can avoid the wastewater concentrative discharging after

the first flood and reduce the pollution to the Bohai Sea.

4.1.4 Public Utility Projects

�Water Supply

After the operation of the wetland project, the comprehensive administration building

will in charge of the plant supplementing, diseases and pests prevention and control, plant

harvest and transportation, plant selling, inflow and outflow quality and volume

monitoring, inflow volume regulation and other administrative work. There are 5

administrative staffs in all. During the plant harvest time, the local peasants will be hired to

harvest the plants, but the employment number depends on the plant volume. The water

volume needed for one administrative staffs is about 80L/d, the water volume for operation

period is about 0.4m3/d and the annual need water volume is 146m3, all the water needed is

supplied by the municipal water supply pipeline networks.

�Drainage

The storm water and wastewater separation system is adopted for the drainage of the

proposed project.

The storm water will be discharged to the nearest water body and the outlet was set up

dispersively.

20

The septic tanks will be established in the waste outlet of the wetland administrative

department and the waste will be collected and treated together and then transported by the

vacuums of the sanitation department periodically.

�Heating

The wetland administrative department will use air conditioners for heating in winter.

4.2 Agricultural Pollution Control and Rural Waste Management

In order to reduce the agricultural and rural wastewater pollution to Guangli River, It

is proposed that several pilot villages will be selected to conduct the pollution control and

management project along Guangli River

�1�Agricultural Pollution Control and Management(4 pilot villages)

Pilot Villages Selection

The pilot villages are Shaotou Village in Xindian Street of Dongying District,

Wangying Village, Shangzhuang Village and Huangdian Village in Shengtuo Town of

Kenli County.

Controlling Measures of the Pilot Project

22

The agricultural pollution control measures for the pilot villages include the

following: Application of the fertilizer pollution prevention and control technology for

cultivation, application of the pesticide pollution prevention and control technology for

cultivation and promotion of the plastic sheet pollution prevention and control measures.

Through the introduction and implementation of the above measures, then we can reduce

the fertilizer, pesticide and plastic sheet pollutions to the water quality of Guangli River.

�2�Crop lands Discharge Treatment(4 pilot villages)

The discharge of the crop lands refer to the runoff from the crop land after the

irrigation or rainfall. Since the outflow is rich in nitrogen and phosphorous of the fertilizer

utilized, so the runoff from the crop lands is easy to cause water pollution.


The pilot villages are Shaotou Village in Xindian Street of Dongying District,

Wangying Village, Shangzhuang Village and Huangdian Village in Shengtuo Town of

Kenli County.

Controlling Measures of the Pilot Project

The designed discharge pollution treatment of croplands is buffer strips + eco-

trenches.300 mus of crop lands were selected as the pilot crop lands nearby the drainage

ditches and the buffer strips width is 10m.

23

The eco-trench system is made of construction and plant components. The cliff and

bottom of the eco-trench are made of cellular concrete board and the cliff has a slope and

small dams will be constructed in the trenches to lower down the water flow speed and

increase the water retention time so that the nutrients will be precipitated and reduced.

Buffer strip refers to the lands with permanent plants to intercept the pollutant of the

wastewater. The buffer strips are constructed along the lands nearby the drainage ditches,

no fertilizer and pesticide used when planting the plants in the buffer strips, the plant can

absorb the fertilizer and pesticides from the outflow from croplands.

Table 4-4 Chart of Eco-trench

5.1 Alternative Analysis for the Wetland

Bio-ecological technology mainly includes biofiltration, wetland, detention pond,

more natural rivers and floating bed plants, ecological slope protection and so on.�

Table 5-1 selection of wetland

Tecnology Advantage Disadvantage Bio- filtration technology

It is especially suitable for severely polluted tributaries of river water quality purification; It has better processing efficiency and higher resistance to shock loads of features of biofilm treatment technology, and stability of filtration technology, is stronger applicability and sustainability;

Suitable for smaller water treatment of water; higher investment; difficult maintenance;

wetland Wetland is a transition zone between land and water, with unique ecological structure and function, and is the natural environment of self-purification capacity .

´ Construction and operation costs is cheaper;

´ Easy maintenance and low technology content;�Good treatment effect;�resistance on hydraulic and pollution load;�Provides benefits, such as aquaculture, planting, Wildlife Habitat, recreation and education.

�Covers an area of large; �in winter, treatment efficiency is not as good as that in non-winter seasons.

detention pond

Using the plants and microbial degradation of adsorption, degradation of organic pollutants in river; It is relatively easy to implement, and manage simple, more suitable for small river with wide river.

Less effective; Used as a pretreatment.

more natural rivers

Building multi - nature ecological river mainly by natural simulation and strengthening of river environmental conditions. Regeneration of river biological communities at the same time, create a good ecological environment and the natural landscape.

investment larger, content larger

floating bed plants

In the polluted river, using wood, foam and other lightweight materials to build floating islands. Floating islands as a carrier, form habitats microbes, insects, fish, birds, plants, form a chain to help water recovery, degradae content of COD, TP and TN. Mainly suitable for organic pollution and eutrophication of rivers

Less effective; Suitable for combine with other technology.

ecological slope protection

Suitable for biological growth of near - natural state of river; simple construction, low cost

Do not suit the place of long-term soaking and slope gradient region�Lower survival rate of

29

vegetation Less effective for larger flow river

Current implementation of artificial wetlands, detention pond and natural river

channel for ecological repairing to the damaged river and water purification has been

increasingly applied.

Construction wetland is the key of comprehensive control of a small valley "

treatment, use and conservation", and is the last barrier purifying pollutants in the Valley.

Success or failure of constructed wetland directly related to the ability to achieve the goal

of river water quality.

Therefore, it is generally reasonable and practicable that combination ecological

detention pond with surface flow constructed wetland as the process of wetland .

5.2 Alternaitve Analysis on Rural Sewage Treatment

Currently mainly rural domestic sewage treatment process includes applications,

stabilization pond, artificial wetland, land processing technology, and so on.

Purification of domestic sewage digester is a decentralized domestic wastewater treatment

equipment, it uses anaerobic digestion and aerobic biological filter combination approach,

incorporating biological, chemical and physical processing together, uses the " multi-tage

fermentation, a variety of multi-level aerobic filtration and purification" to achieve gradual

removal of multiple pollutants in wastewater.

Septic tanks are a precipitation and anaerobic fermentation theory, suspension of organic

matter removal in sewage treatment facilities, transitional living structures belonging to the

primary.

Stabilization pond has a pond embankment and impermeable layer, its main use of

aquatic biological systems, relying on natural biological purification of the sewage to be

purified, is rapidly promoting wastewater treatment process, implementation of effective

methods of sewage resource utilization and stabilization pond treatment technology in

recent years.

Artificial wetland is the structure filling certain selected graded fillers at the bottom,

such as gravel, sand, peat, and packing plant for sewage well in surface soil, high survival

rate, longer growth period, beautiful aquatic plants, such as reed.

Land treatment system is a technology that put the sewage to the soil layers with a

certain structure and good diffusion properties, using infiltration of soil capillary diffusion

30

principle, energy flow through the cycle of matter in ecosystems and gradual degradation

of pollutants, purification of sewage treatment systems.

Table 5-2 selection of rural domestic sewage treatment process

Process Advantage Disadvantage Anerobic treatment

1. suitable for treatment of high concentration wastewater from livestock and food processing waste water. Sewage treated can be directly used for irrigation or discharged into the waters of the rivers. 2. Low construction cost, high efficiency, high environmental and economic benefits 3. Sewage treatment and utilization of organic integration enables reuse of wastewater.

In winter when the temperature is low, the process of handling efficiency will be reduced,so need require heat preservation

Septic tank less investment, easy maintenance, simple process, suitable for smaller rural sewage treatment.

A longer treatment time; Covers large area;

Stabilization pond

With low infrastructure investment, low running cost, management and maintenance easy, stable and reliable operation

Covers large area; Purification effect is easily affected by natural factors ,such as temperature.

Artificial wetland

Batter treatment effect, and has a strong capability of nitrogen and phosphorus, operation and maintenance convenience, simple management, low investment and operating costs

Covers an area of much higher than traditional treatment process; Greater impact of seasonal change on wetland

Land treatment system

energy efficiency, low operating costs Limited by the growing season of crops, Non-growing season of crops without irrigation, wastewater treatment system will not work

Because rural domestic wastewater is less, water quality single, existing parts in the

villages surrounding ponds available, taking into account the construction scale of the

project, process, requirements, project investment, operating costs and maintenance

management, we select applications in combination of Septic tank and stabilization pond to

treat of domestic wastewater process.

6.1 Brief Introduction to the natural environment

�1�Geographical Location

Dongying city is located in the Yellow River Delta of Northern Shandong Province. The

Yellow River—the mother river of Chinese nation, enters the sea within the territory of

Dongying city. Dongying lies at 36°55 �38°10 north latitude and 118°07 �119°10 east

longitude. It borders on Bohai Sea on the east and north, and has a total area of 7,923

square kilometers.

Guangli River is the main drainage channels running through the center city of

Dongying. It runs through Dongying District and Kenli County and is the only river

connecting the Yellow River and the Bohai Sea. The River starts from Nanzhan Dam

Wangying Gate of Yellow River, runs through the center city and converge with Yihong

River into Bohai Sea by Guangli Port. It is about 60km, drainage area is 510 km2. It played

an important role in the water supply, drainage, flood control and improving the ecological

environment.

(2) Topography and geomorphology

The main physiognomy of Dongying is plain. The Yellow River flood punches the

surface frequently historically, so it shapes the complex Subminiature Terrain. The ground

falls away from the southwest to the northeast along the Yellow River. The maximum

32

elevation of the southwest is 28 meters, compared with that the lowest elevation of the

northeast is 1 meter. The natural ratio of reduced is 1/8000 ~ 1/12000. The maximum

elevation of the west is 11 meters, the lowest elevation of the east is1m, the natural ratio of

reduced is 1 / 7000. Yellow River passes through, and becomes "Ground river higher than

its banks" respectively. The city has 5 types of micro-topography: the ancient flood

heights, accounting for 4.15% total area of the city, mainly in the upper reaches of the

Yellow River burst fan; flood heights, accounting for 3.58% of the total area of the city,

mainly between the Yellow River to the levee; micro-inclined flat, accounting for 54.54%

the total area of the city; the transition zone of depression; shallow depressions, accounted

for 10.68% of the total area of the city.

The south area of the Xiaoqing River mainly is constituted with the ancient highlands,

the north of the Xiaoqing River mainly is constituted with microcline into the ground;

beach, accounting for 27.05% of the total area of the city, show the zonal distribution and

parallel to the coastline.

�3�Surface water

The city had 30 key drainage channels totally beside the Yellow River. By the Yellow

River for dividing line, the south of the Yellow River belongs to the Huaihe River Basin,

and the north of the Yellow River belongs to the Haihe River Basin. The river in the Huai

basin strikes almost EW, except 20 rivers which strike SN, including the Xiaoqing River

and its tributaries, Zhimai River and its tributaries and the Guangli River and its tributaries.

The rivers in Hai basin are mostly from south to north, exept 10 rivers which strike EW,

including Chao River and its tributaries, Caoqiao River, Tiao River, Shenxian River and its

tributaries.

precipitation, the main discharge is surface evaporation. During the survey, groundwater

depth is about 1.6m, and the relative elevation is about -1.9m (March 7, 2010), amplitude

of groundwater each year is about 2.0m.

�6�Sea

The coast of Dongying starts from Jianggou estuaries in the north, end in the

Zimaigou estuaries in the south, the total length is 412.67 km, accounting for about 1/7 of

the coastline of Shandong Province. Beach area is 152 acres, within the -10m isobath,

shallow sea area is 4,800 square kilometers. The seabed along the coastline is relatively

flat, water transparency is from 32 to 55 cm. Seawater temperature and salinity are

influenced by the continental climate and the Yellow River runoff greatly. The tide in the

most part of the semi-closed sea belongs to the irregular semidiurnal tide, the average tidal

range is from 0.8 to 1.2 meters, the highest tide is more than 5 meters. So it is easy to occur

storm tide.

(7) Climate and weather

Dongying City is located in the middle latitudes, back the land and face the sea.

Effected by the Eurasia and the Pacific combined, Dongying belongs to the warm

temperate continental monsoon climate. Basic features of the climate are cold winter, hot

summer and with four distinct seasons. No significant differences within the North-South

climate. The mean annual temperature is 12.8�, crops satisfy three crops for two years.

(2) The river water pollution situation of Guangli River

The investigation results along Guangli River, Five Six together row, and Old Guangpu

Trench by the Environmental Protection Bureau of Dongying City in mid-April 2009

showed that there are a total of 157 outfalls including 73 direct outfalls, 27 Flap valves, 14

Pumping station overflows and 43 drain ports. Guangli River and tributaries accepted

sewage nearly 4 million tons, of which more than 90% are urban sewage, the rest are

industrial waste. Tables 6-3 show the pollutions situation of Guangli River.

The above table shows that the water quality of Guangli River is far exceeding the

functional requirements of the "Surface Water Environment Quality Standard"(GB3838-

2002) class standard.

(c) Undergroundwater

According to the routine monitoring data of Dongying City, the other of the

monitoring projects except NH3-N and total coliform of groundwater monitoring points in

evaluation area were able to achieve Class � of "Water Quality Standards"(GB/T14848-

93).

(d) Acoustic environment

The project area is mainly farmland and water, almost no noise source, only the natural

noise. Acoustic environment quality is good.

(e) Ecological environment

� Status of vegetation: The wild vegetation along Guangli River mainly are herbaceous

vegetation including reed grasses, huangxu vegetables, thatch, Sargassum, etc..

Herbaceous roots in many years are the main subjects, such as reed, Po son, reed grass in

low-lying land, etc. Trees in the evaluation region were all planted, including locust,

poplar, willow and other types of strong adaptability.

In short, the herbaceous plants are main species in the area. The plants species are

common and general. There are no protected plants and rare plants in evaluation areas.

Plant species are not diverse.

� Status of wild animals: According to the survey, birds include sparrows, magpies,

mallard, gulls, etc; land animals have yellow weasel, hedgehog, mouse, rabbit, etc.; reptiles

are snakes, lizards, geckos and so on.

2. The major environmental issues

A. A large number of untreated sewage spilled into the river directly

¾ Rain and sewage mixed emission in West City is serious.

¾ Sewage treatment plant construction is lagging behind.

¾ Supporting sewage pipeline is incomplete, construction quality but off.

¾ Part sewage wells are not installed trash grille, siltation is serious; part inspection

well set up along interception trunk is blocked because poured a large number of

construction waste and sediment in cross construction that leads to poor

sewerage, sewage spills into the Channel.

¾ Pump station design is unreasonable along the river, facilities is inadequate

37

B. Non-point source pollution caused serious pollution of Guangli River water ¾ Fertilizer pollution

¾ Pesticide contamination

¾ Plastic sheeting pollution

¾ Stool contamination of livestock breeding industry

¾ Rural non-point source pollution. Water pollution control plan was not

established during the comprehensive management of Guangli River. Heavy use

of farm pesticides and fertilizers along river caused agricultural non-point source

pollution and polluted water by farmland irrigation tail water and seepage field

into Guangli River.

C. No external water caused the river water quality gradually deteriorate in dry season

Dongying is a less water city because of less precipitation and large evaporation. It relies

on sewage into river to supplement water level in dry season because no fresh ecology

water adds. There is only a small amount of irrigation tail water and seepage in the river

and can not form a runoff after sewage into the urban sewage pipe network through the

interception and guide sewage projects. Because intercepted by the River Gate,

saprophytes are easy to breed in water and cause deterioration of water quality.

In view of the above problems, it is imminent to Implementation wetland engineering of

Guangli River and control agricultural and rural non-point source pollution. Project

implementation can effectively solve the issue.

6.4 The main environmental objectives

Project construction may have some effects on the surrounding villages and

companies. The surrounding 1km within wetland has no village, but has 4 companies, the

specific position and distance in Table 6-4. Agriculture and rural non-point source

pollution control project designs several villages, and the construction process will take

some impact, specifically in Table6-5.

The main environmental objectives around the project area are showed clearly in

7.1 Project Analysis

7.1.1 Processs flow

The construction of wetland includes sluice and pump station, ecological retention

ponds, surface flow wetland and other match facilities.

The work content of wetland project and the agricultural and rural pollution control

project include earth excavation, slope protection, construction of various infrastructures

etc. The environmental impact of projects mainly is in the construction period, so EIA

focuses on the construction period of the process.

7.1.2 Analysis factors

(1)Construction period

Atmospheric environmental factors

The main factor is dust generated in earth excavation, piling, transportation and fuel

emissions generated by machinery.

The large wind is likely to produce more dust, increase suspended particulate matter

in the air, bring some negative impact to the surrounding environment. General

construction dust mainly affects on both sides of road within the scope of 60m.

Fuel machinery and transport vehicles in the construction process will exhaust

wastegas, primarily NOx, THC and other atmospheric pollutants to affect on the

surrounding environment.

Control Measures:

Equip with cleaning facilities; stamp with tarpaulin to transport vehicles; water

regularly the Pile field; forbid the throw-type loading and unloading; apply the high quality

fuelsto machinery and transport vehicles; add gas purification device to vehicles.

water environmental factors

The main factors are sewage of workers, washwater of machinery and vehicles,

concrete curing wastewater, pit drainage and so on.

Control Measures:

Install the simple toilets, sewage is collected and used as agricultural fertilizer, reuse

the concrete curing wastewater precipitated by sedimentation tank, reuse the washwater of

machinery and vehicles precipitated and separated by sedimentation tank.

noise factors

The nosie generated by machinery and vehicles has an impact on the surrounding

environment and interferes with people’s living and rest.

Construction machinery is the main noise source, noise sources in the construction

zone flow pattern moving. Construction noise mainly occurs in the small piling, concrete

mixing and the process of carrying earth, and noise level is about 70 ~ 105dB (A). The

main noise equipments and the sound level can be seen in Table 7-1 as follows:

Control Measures:

In construction process it should pay attention to reduce the man-made noise, take

appropriate measures to reduce impact on environment, add sound insulation, rationalize

the using-time of noise equipments, avoid construction at night, etc. At the same time,

select the appropriate location for equipments; use the natural condition to minimize the

noise impact.

solid wastes factors

The solid wastes include roots, gravel, scrapped soil, useless materials, garbage, and

so on.

Control Measures:

Roots, gravel, scrapped Soil, garbage (20t/a) are collected by the municipal sanitation

department and transported to the local waste disposal sites; useless materials should be

recycled by manufacturer.

Impact factors on ecological environment

Impact factors:

First, various types of plants within the occupied land will be eradicated, cut down, so

that the vegetation has been permanently damaged.

Second,because of the excavation and cuting down the plants�bare land could easily

lead to soil erosion by rain.

Third, all kinds of small animals such as voles and small reptiles are frightened and

forced to move to another place or death by construction process.

Due to relatively short period of construction time, from the long and regional

perspective, both the destruction of vegetation and the impact on the animals are smaller.

Control Measures:

44

For the inevitable ecological impact, it is necessary to develop the ecological

compensation measures to make up the loss of a certain ecological impact, and develop

temporary protective measures, land management measures, plants measures to make up

the soil erosion.

Impact on people

Infectious diseases are easy to spread in the onstruction site. As the living conditions

of the site and the relatively poor sanitary conditions, labor-intensive workers, will lead to

reduced capacity to resist disease, increase the risk of infection in long working hours.

Control Measures:

The saff need wear the necessary protective measures, such as gloves, masks, etc.

Other, arrange reasonable working time for workers, and reserve essential drugs.

�2�Operation period

This project belongs to the river pollution control project, the pollution factor is few.

During the operation relatively, emission are mainly sewage and garbage of workers.

Wastewater

The five workers are responsible for replanting of plants, pest control, plant

harvesting and removal, plant sales, and routine monitoring of the water quality of

wetlands, water quantity management. The amount of sewage generated is 0.32m3/d

(116.8m3/a), and the sanitation department is in charge of collection the sewage on a

regular time.

Gas

This project does not have air pollution sources, and relies on electric heating. So this

project belongs to non-polluting project.

solid wastes

There is no other solid waste except the garbage of workers. The garbage (0.91t/a) is

collected by the municipal sanitation department and transported to the local waste

disposal sites.

Impact factors on ecological environment

With the function of various wetland plants to gradually play, the ecological

environment is recoveried. Expansion of the vegetation area impacts the local micro-

climate and improves local ecological environment.

After the project operates, effects on the ecological environment and landscape will

be improved.

45

7.2 The generation and emission of pollutants and control Measures

As the environmental projects, the generation and emission of project pollutants and

control measures can be seen in Table 7-2 as follows:

7.3 Environmental Impact Analysis

7.3.1 Environmental Impacts of wetlands during the construction period

7.3.1.1 Environmental Impacts on ecological environment

The structure and function of regional ecosystem will be re-adjusted to impact on the

ecosystem.

After the wetland is constructed completely, the original project area aquatic and

terrestrial ecosystems will gradually become wetland ecosystems. After the water quality is

improved of the Guangli River, aquatic ecosystems which are seriously polluted now will

change to the clean aquatic ecosystem, and it is good for ecological restoration.

�1�Environmental Impacts on biology

Environmental Impacts on vegetation

Construction activities such as Excavation, stack etc will bring varying degrees of

damage to regional vegetation, and even become secondary bare. The vegetation of other

area does not be affected except Construction site.

These plants are widely distributed species, rather than rare species. Therefore, the

impact of construction on the plant will lead only to reduction in the number, not the

extinction of species. So the impact is local and will not bring the greater impacts to the

regional ecosystem.

Environmental Impacts on wild animals

Environmental Impacts on wild Animals during the construction period are:noise; part

of the vegetation is destroyed; Construction will cut off the movement channels of certain

animals, thereby affect the flow of the Species.However, due to strong migration of wild

animals, those effects are temporary and partial,until the end of the construction will come

to an end. The wild animals are the local common species (such as sparrows, magpies, rats,

rabbits, snakes, etc), because of their migration and protection of animals, combined with

the project covers an area is relatively small the impact on wildlife.

�2�Environmental Impacts on soil

Because of excavation within a certain area, the soil is disturbed and destroyed the

original layer, even the arable layer. Excavation affects the soil fertility of the original

topsoil, thereby affecting plant growth and yield. In addition, sewage, wash water, and

solid waste may increase the load of soil pollution, as much as possible to handle them

properly. There is not rare of soil organisms in this area, the destruction to the soil is

temporary, so the ecological balance will soon be restored.

49

�3�Environmental Impacts on occupied land

The types of land occupied by the project mainly are wasteland and depression, and

the construction of the project will change the types. according to preliminary plans, the

project will cover permanently an area of 2698.5 acres. If a large number of spoil

generated by excavation can be timely filled, used and minimized its exposure time, it can

greatly reduce soil erosion. Almost all the excavated earth and stone can be backfilled.

�4�Impact on people

There is no village but 4 factories range 1km around the construction site. The types

of impact on people are: blocking traffic, mechanical noise, dust, construction scene etc. It

is necessary to take certain measures during the construction to control its impact within a

certain range, thereby reducing the impact on the population. According to public

participation, surrounding factories support for the project.

�5�impact of soil erosion

The soil erosion mainly takes during the construction period, so we identify

construction period as the forecast period. The total area of disturbance of the original

landscape, damage to land and vegetation is 209.9hm2. Almost all the excavated earth and

stone can be backfilled.

The project construction may make the soiland rocks stripped, vegetation damaged,

soil erodibility added, soil fertility decline, even affect the ability of storage and flood

control, so it has to take the positive control measures.

Control measures:

take the exposed surface around the wetland to be green; plant shrubs, grass etc to

protect the road, plant low shrubs around the management office.

Set the a temporary wall and drain around Spoil yard to avoid rain to wash out on

the surrounding environment.

It is necessary to take the appropriate measures to preserve stability of the

embankment, and focus on drainage works.

Engineering work should be tried to avoid scheduling during the rainy season or

before the rainy season to reduce soil erosion in construction period.

�6�Impact on risk

If the pollutants of Guangli River are far beyond the purification capacity of wetlands,

it could be led to large-scale pollution of wetland, weaken purification function, increase

eutrophication, so it needs control the concentration of river.

50

�7�Impact on landscape

landscape structure

After the completion of the project, landscape structure will change substantially, and

most of the original landscape will disappeared. The area landscape will be changed from

the reservoirs, saline, farmland into wetlands.

Combination of land using changes in the structure, the landscape structure of project

area is made of retention ponds, manmade wetlands, slope and construction of structures.

landscape function

Landscape is dominated by manmade wetlands. Purgative function of wetlands which

play more action will gradually improve the environment, thus promoting local economic

development.

�8�Control measures:

construction should be srictly in accordance with design, reduce the amount of

foundation excavation and the construction of the spoil. Stack the excavation better for site

preparation.

During the construction and installation, arrange the scope and route, do operations

in accordance with regulations. Strict control and manage the scope of transport vehicles

and heavy machinery, minimize damage to existing vegetation and soil.

Forbid stacking materials randomly and designate the appropriate stack yard to

prevent the expansion of the scope of plant damage.

Should be excavated stratified according to the implementation of practice. Top soil

should be stacked separately with the underlying soil; backfilling should also be layered as

much as possible to maintain the original ecological environment. Accumulation should

also leave enough appropriate level; prevent precipitation and runoff to lead to soil erosion

and surface subsidence. The remaining soil should be tiled in the field, forbid not being

thrown away.

Do well the work of land reclamation, clean up the scene. Parts damaged by the

vehicles and machinery must be repair and restore timely.

After construction is completed, destruction of vegetation must timely restore.

�9�Invasion of exotic species

Wetland plants growing and around the slope greening in all process should pay

attention to the invasion of exotic species. Once discovering of harmful exotic species,

should take removing, inhibiting or control measures as soon as possible, to reduce the

51

negative impacts. The control plans need to be developed, require the direct participation

of ecologists, demonstrate fully the approach, and avoid causing more ecological damage.

Also it needs to reach a consensus and support with local residents.

7.3.1.2 Ambient air impact analysis

The main factors are dust generated in earth excavation, piling, transportation and fuel

emissions generated by machinery.

The amount of dust is relevant to many factors, such as construction site conditions,

management level, degree of mechanization and the construction season, soil and weather,

etc. General construction dust mainly affect on both sides of road construction within the

scope of 50~200m. Spraying water is a good way to inhibit the dust, which cuts 80% of the

dust.

Fuel machinery and transport vehicles in the construction process will exhaust

wastegas, affect on the scope of 50m. The amount is smaller and open construction site is

easy diffused for pollutants, so the dust impacts less on environment.

Because there is no village within the range of 200m around the construction site,

Construction dust less impacts on surrounding villages.

7.3.1.3 Surface water environmental impact

The main factors are Sewage of workers, washwater of machinery and vehicles,

concrete curing wastewater, pit drainage and so on.

Install the simple toilets, sewage is collected and used as agricultural fertilizer, reuse

the concrete curing wastewater precipitated by sedimentation tank, reuse the washwater of

machinery and vehicles precipitated and separated by sedimentation tank.

Therefore, the wastewater produced during construction has little effect on the

surrounding environment.

7.3.1.4 Noise environmental impact

Machinery and vehicles will generate the noise, including: excavators, mixers,

vibrating rods, concrete trucks, bulldozers, impact drill, air compressor, welding machine,

etc.

Because there is no village within the range of 200m around the construction site, the

noise less impact on surrounding villages.

7.3.1.5 Solid waste

The solid wastes include roots, gravel, scrapped Soil, useless materials, garbage and

so on. Roots, gravel, scrapped Soil, garbage are collected by the municipal sanitation

52

department and transported to the local waste disposal sites; useless materials should be

recycled by Manufacturer.

The measure treated solid waste is reasonable and practicable, and it has little effect

on the environment.

7.3.2 Environmental Impacts of wetlands during the operation period

7.3.2.1 Environmental Impacts on ecological environment

Once the project is completed, due to construction damage and affecting factors of

soil erosion after the measures implemented gradually disappeared, reduced until it reaches

a new stable state.

Through ecological greening project, operation period of significant reduction in the

volume compared with the present situation of soil erosion, and soil erosion modulus

becomes significantly smaller.

7.3.2.2 Ambient air impact analysis

This project does not have air pollution sources, and relies on electric heating. So this

project belongs to non-polluting project.

7.3.2.3 Surface water environmental impact

Period of operation wastewater is mainly management’ sewage (0.32m3/d), and the

sanitation department is in charge of collection the sewage on a regular time. Therefore,

the project impacts less on Surface water environment.

The wetland projects after the completion, can effectively reduce point source and

non-point source pollution load may reduce pollutants CODCr (430t/a) and of NH3-N (129

t/a) of the guangli River into the sea. Project construction will enable certain improvement

in water quality in the Bohai Sea. At the same time, purified water returns to the huanghe

Road water system, improves water quality, and reduces the water supply from the

upstream water resources(e.g Wugan Channal).

7.3.2.4 Underground water environmental impact

The wetland projects don’t produce wastewater except Sewage. For regional

geological conditions better, the wetland don’t lead infiltration to pollute groundwater. As

long as strengthening the pipeline maintenance and necessary anti-seepage measures, the

project does not have a larger impact on groundwater.

7.3.2.5 Solid waste

The solid waste is mainly garbage (0.91t/a) which is collected by the municipal

sanitation department and transported to the local waste disposal sites.

53

In winter the wetland will harvest the plant s which are recycled and utilized by the

around villagers. The sludge in wetland needs to be cleaned on a regular time. Because of

belonging to a general solid waste, the sludge can be sent to the landfill and does not affect

the normal operation of the landfill. So the project does not have a larger impact on

environment.

7.3.2.6 Impact on landscape

The project changes the original appearance, increases the new landscape of wetland,

selects the appropriate green way combining organically with the surrounding

environment, and improves greatly water quality of the Guangli River.

In short, through the development and effective utilization of land, the project can

change the environment of the city landscape, link engineering and environment, and

improve the local landscape conditions. Therefore, the negative effects of projects on

landscape environment are small.

7.3.2.7 Health protection of workers

The workers need wear the necessary protective measures, such as gloves, masks, etc.

It is necessary to set railings and other protective measures to prevent security

vulnerabilities.

7.3.2.8 Relocation

There are 7 units in the area that wetlands cover.;�Relocation would not have adverse

effects on land because they are not involoved hazarouse production (e.g chemical).

Relocation of the original 7 units will not cause greater impact on the surrounding

environment.�

7.3.3 Environmental Impacts of Agriculture and Rural Pollution Control Component

7.3.3.1 Positive impacts

The investments in Agricultural Pollution Control Sub-Component will have the following

positive imapcts:

(a) Reduction of fertilizer pollution through use of alternative green/organic fertilizers, and

precise application practices in the pilot villages. This includes use of alternative green

fertilizers and precise application for winter wheat and corn crops, controlled precise

fertilizer applications for paddy, balanced fertilizer application for cotton (based on soil

fertility test results); as well as related training and technical assistance/extension services.

It is expected that fertilizer use would be reduced by 15-20%, and utilization rate increase

by 5-10%, leading to substantial nutrient loads (N, P) reducation to the Guangli River and

significant cost-savings for the farmers�

54

(b) reduction of pollution for pesticide use through public awareness raising, training and

technical assistance, channeled through FEPAs, for reduced use of pesticides and adoption

of alternative green technologies such as moth-killing lamps (us of such lamps each

covering for 3-4 ha area for demonstration purpose). These interventions are expected to

reduce the pesticide use by 20% or more, resulting in both pollution reduction and cost

savings;

(c) best practices for managing agricultural runoff (irrigation return flow and precipitation

runoff from farm fields), to reduce nutrient and pollutant loads entering the Guangli river.

Approaches include eco-trench, conservation buffer-strip, learning from international

experiences. A farm area of 20 ha will be selected in each pilot village to apply the

recommended technologies. The result expected is up to 90% of the pollutants from

agricultural runoff removed in the target farm plots.

7.3.3.2 Negative effects

The negative impacts and mitigation measures can be seen in table 7-3.

7.4 Social Impacts Analysis

7.4.1 Ecological and Landscaping Effectiveness

Various kinds of plants are planted in the wetland, such as bamboo reed, bulrush,

cattail, lotus and hornwort, etc, willows, pseudo-cacias and other arbors were planted along

the weirs and roads, then the stability of wetland system will be achieved which is mainly

to reduce pollutants(e.g N,P) from the Guangli River. The ecological environment along

the river banks and the outflow water quality discharged to Bohai Sea will be improved

with the completion of the Dongba Road Wetland. The wetland system may become the

habitat and food source for the waterfowls which plays an important role in biodiversity,

ecological system stability and local climate regulation.

7.4.2 Social and Economic Benefits

After the completion of the wetland construction and rural pollution management, the

river water quality will be improved and create a wetland landscaping which will improve

the living environment quality of the residents. The proposed project plays an important

59

role in water supply, flow volume regulation, flood control, embankment protection and

toxic pollutant reduction, and the project contributes to the water quality of Bohai Sea.

Besides, the wetland has the function for natural sightseeing, tourism and entertainment

which can create a direct economic benefits. Meanwhile, the wetland has education,

scientific research and cultural values and can increase the environmental protection

awareness of the local residents and tourists.

7.4.3 Social environment impact analysis

7.4.3.1 Wetland

�1�Positive impact

First, Guangli River and the Yellow River Road system is a core component of the

strategic planning of low-carbon eco-city of Dongying city. Projects to accelerate the

efficient construction of ecological economic zone in the Yellow River Delta in Dongying

city, has laid a good foundation. In 2010, urbanization rate of 58.5 in Dongying city, in a

phase of rapid urbanization, high speed difficult to avoid the destruction of ecological

environment in the development process. Project construction has a far-reaching

significance to enhance the quality of urban development, urban development patterns,

promoting sustainable development of cities,

Second, the construction project on the wetland system in Dongying city as a whole,

have improved water quality, landscape and improve river flood control storage capacity

effects. Project involves the Guangli River and the Yellow River Road. The watland

connected Guangli River and the Yellow River Road water system, will promote the

Dongying people’s welfare.

Again, after the renovation of wetland landscape, itself is a public product. As a trunk

River along the Guangli River of Dongying city, is a leisure place for local residents.

Finally, Dongying city close to the Bohai Sea, evaporation is greater than

precipitation, scarcity of freshwater resources. Guanglihe runs through the urban area of

Dongying, river water quality pollution eventually harmful Dongying people’s drinking

water health. By wetland construction regulation of ecological environment, can purify

water, change this situation.

�2�negative effects

Wetland construction project involves several enterprise’s relocation during

construction. Wetland construction project will occupy newly dug fish ponds and have an

adverse impact on fisheries production. In 2010, many fish ponds started construction,

60

some of them are forming. Project construction will make it difficult for fish pond owner’s

investment pays off.

7.4.3.2 Agriculture and rural pollution control projects

�1�Positive impact

In the harmonious development between human and environment concept under the

guidance of the Government, has introduced a series of initiatives to improve the

ecological environment in Dongying city. Rural sewage treatment is a low-carbon eco-city

construction of Dongying one of the many initiatives. In 2009, municipal wastewater

sewage treatment plant in Dongying city focused on rate of 75.8, away from the urban

rural sewage treatment rates of almost 0. Rural sewage treatment project can improve rural

sewage treatment capacity in Dongying city, helped to further enhance the city’s sewage

treatment capacity.

Guangli river in its upper and middle reaches has dual functions of both

environmental and irrigation. Before the project construction, the live production sewage

of DongJi town and shengtuo town discharge into guangli River untreated. Villagers use

River water diversion irrigated farmland, forming secondary pollution of the soil.

Construction of sewage treatment facilities can improve the capacity of rural sewage

treatment, reduce sewage pollution of the water, thereby reducing the costs of pollution

prevention, guarantee water health.

Now in Dongying Rural area sewage treatment is mainly through septic tanks. When

the septic tank is full, dung is excavated, piling up along the street for a while, used as a

farmyard manure. Livestock Farmers have a large amount of livestock manure, which are

stockpiles without shetler. During wet season, faecal sewage infiltrates to groundwater,

leading to disease. Especially those personnel and institutions such as schools, factories

using groundwater as water source more likely suffers high incidence of diseases caused

by sewage. Once the concentrated outbreaks of these diseases, it will seriously affect

people’s work and life, increase family additional medical costs.

Environmental protection associations committed to the promotion of environmental

awareness of farmers, to make existing environmental protection facilities in rural areas in

Dongying city, such as trash, played its best features. Environmental protection manual

will guide the peasants under different soil and crops, targeted drugs, fertilizers, increased

agricultural output, enhance revenue.

�2�negative effects

61

For construction and operation of sewage treatment facilitie in each counties, the

biggest change to the local community means that the pipeline within families and

communities pipes need to be laid and connected to sewage treatment facilties. Piping

system of family and community incur cost. If it is fully borne by the masses, those

families which is further away from the main sewer network hasve to bear more burdens,

generating new social injustice.

For maintaining the normal operation of a wastewater treatment facility, owners need

to charge a small sewage treatment fee, to achieve the guaranteed low - profit level sewage

treatment plant. In 2009, Dongying peasants’ annual per capita net income is $7326.91, and

it is a low level in the eastern coastal cities in Shandong province. From families with

lower incomes, increasing the sewage charge is not a small burden.

Agricultural non-point source pollution control avtivities located in farmland. The

construction period, may result in damage to agricultural crops, reduce crop yields, thus

reducing the farming peasants’ income.

9 Conclusion and proposals

9.1 Conclusion

�1�Project Summary

The total investment for the proposed project is 0.2570678 billion RMB. The projects

include: the wetland and sluice gate operation optimization; Implement the agricultural and

rural pollutant reduction in the pilot villages along the Guangli River to reduce the

pollution to the the Guangli River; Strengthen the capacity building, policy development

and project management to increase the capacity of project management and PIU and

achieve the sustainable development. After the completion of the proposed projects, the

pollutant from the sources will be reduced effectively and the pollution to the surface water

of Guangli River will be improved, the water sources will be protected, developed and

utilized effectively and the pollution to the Bohai Sea will be reduced with a total CODCr

of 430 t/a and total NH3-N of 129 t/a.

�2�environment quality

The environmental air quality can meet class of the "Environment Air Quality

Standard "(GB3095-1996); water quality of Guangli River can not meet Class �of the "Surface Water Environmental Quality Standard"(GB3838-2002); Acoustic environment

quality is good and can meet class of Environmental quality standard (GB3096-2008).

�3�Environmental impact analysis

Ambient air impact

During construction period, it needs to take water to decrease dust.

During operation period the project has no air pollution sources, so less impact on

ambient air.

Surface water environmental impact

During construction period, sewage is collected and re-used, the concrete curing

wastewater precipitated by sedimentation tank is reused.

During operation period, the sanitation department is in charge of collection the

sewage on a regular time. Therefore, the project impacts less on Surface water

environment.

noise

In construction process it should pay attention to reduce the man-made noise, take

appropriate measures, add sound insulation, rationalize the using-time of noise equipments,

71

avoid construction at night, to reduce impact t on environment. Because there is no village

within the range of 200m around the construction site, the noise less impacts on

surrounding villages.

Solid waste

Garbage is collected by the municipal sanitation department and transported to the

local waste disposal sites, other solid waste should be recycled or effectively treated. So it

has little effect on the environment.

Impacts on ecological environment

The impact of construction on the animals and vegetation is temporary without

adverse impacts on any endangered species. Afte the completion of the project, water

quality improvement will contribute to a better eco-system.

The impacts on soil is temporary, and the ecological balance will soon be restored.

With the function of various wetland plants to gradually play, the ecological environment

is recoveried. Expansion of the vegetation area impacts the local micro-climate and

improves local ecological environment.

To sum up, the project can purify Guangli River, reduce rural sewage pollution to

guangli river, improve regional eco-environment, reduce the influence to the Bohai Sea

impact. The project conforms to national industrial policy, the measures taken is

reasonable and practicable, and does not have adverse effect on the environment of the

region.

9.2 Measures and proposals

(1) Measures

Strengthening management of the various materials in transportation and storage,

especial cement. Into the construction site of cement to focus stacking, and covered canopy

cloth, avoid windy make cement dust flying all over.

Various materials in the construction site need to focus stacking, and cover canopy

cloth, avoid making dust in windy day. It needs to take water to decrease dust. The

sanitation department is in charge of collection the sewage regularly.

Construction should be srictly in accordance with design, reduce the amount of

foundation excavation and the construction of the spoil. Stack the excavation better for site

preparation.

72

all vehicles shall be in accordance with the regulations on the road, avoid free to

drive everywhere, destroy the vegetation in the region, easily lead to local wind erosion

phenomenon.

In strict accordance with the EIA specified control measures. When the project is

completed, it must accept the department in charge of environmental protection.

�2�Recommendations

Increase enforcement of environmental protection in the guangli River basin,

strictly control illegal construction projects. Strictly implement of the environmental

impact assessment and " three simultaneities " system.

Increase agricultural non-point source pollution control, addressing use of

chemical fertilizers, pesticides, of plastic sheeting in the agricultural production,while

vigorously addressing rural sewage. Measures should be taken in the agricultural sector,

guiding local farmers adjust planting industry, etc.

The wetland is a systematic project, and it must be combined with management

measures. It must have long-term effective management, to project benefit into full play, so

as to achieve the objective of this project. Relevant government departments need to do

further detail of the investigation and analysis, so as to lay a solid foundation for the next

project.

It Should be excavated stratified according to the implementation of practice. Top

soil should be stacked separately with the underlying soil; backfilling should also be

layered as much as possible to maintain the original ecological environment. Accumulation

should also leave enough appropriate level; prevent precipitation and runoff to led to soil

erosion and surface subsidence. The remaining soil should be tiled in the field, forbid not

being thrown away.

7he sewage shound be transported timely by the sanitation department, prohibit

any emission, to avoid impact on surface water environment around.

Strengthening supervision, ensure construction of the relevant requirements have

been implemented, avoid causing the local ecological damage and soil erosion without

strict management.
