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.

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.

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.

�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.
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
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.

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.

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 above table shows that the water quality of Guangli River estuary is much higher than
the standard value. The pollution is more serious.
(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.
