1.4Environmental impact analysis conclusion
1.4.1Environmental impact analysis during construction period
- Ambient air
In this project construction process, the factors which influence the ambient air are Stench, construction dust and gas construction machinery.
Through field investigation and comparison analysis, the stink caused by this project is low-intensity., whose sphere of influence is about 30m. And the Stink only exists in the construction period, which will disappear with the end of the construction.In the public opinion surveys, most of the people surveyed said the stink caused by the project was acceptable.
The construction dust is mainly composed of vehicle transport and construction of soil, whose sphere of influence is within 100ms. The mechanical exhaust mainly consists of various transportation vehicles and fuel mechanical emissions, whose sphere of influence is within 50 meters around the site. By taking certain effective pollution prevention measures, theconstruction dust pollution can be effectively controlled. The Mechanical exhaust quantity and the pollutant concentration is low. As long as the Supervision and management to the exhaust of all kinds of vehicles and equipment are done well, the impact on the environment will be basic.
- Acoustic environment impact analysis conclusion
In this project construction process, the noise caused by all kinds of construction machinery and equipment impacts on the environment much. The noise generated in the construction site around about 20m can achieve the standard requirement.If the Project construction takes effective measures for the prevention and control of noise pollution and effective environmental supervision, reasonably designs the engineering construction scheme, the project construction noise impact can completely be lowed to public acceptable level, and the environmental impact can be minimized as well.
- Environmental impact analysis of solid waste.
The solid waste produced by this project construction mainly includes Channel sludge and various bait-casting rubbish. The River sediment of Ganhe, zhuohe and Migouhe is hazardous waste, which can be directly transported to Zhoucun HeishanLandfill for disposal. Thevarious soil and construction waste from the construction can be dissolved by the filling for other urban construction projects, and Residual soil and construction waste can disposed by Zhoucun HeishanLandfill. Life waste can be transported to Zhoucun city rubbish landfill for unitydisposal .
- Water environment analysis conclusion
The wastewater from this project is mainly construction waste and sewage effluent. Due to the construction site is located in downtown zhoucun, after collecting all the wastewater comes into the city drains, The emission of the wastewater will take adverse effect on the surroundings.
- Ecological environment impact analysis conclusion
The project will build greening of 176298m2 along the river banks, which canimprove the regional ecological environment.
Project construction area is not permanent and the Temporary area is small, both of which is in the urban area. and only few of them have surface vegetation. This Engineering construction will make this part vegetation disappear for a short time, but With the construction ended, and after the repeated covering and greening,this part of the land vegetation will recover gradually .
The effect of the channelcleanouton the aquatic organisms is temporary and with the end of regulation river bait-casting, the rivers will become clear,The aquatic organisms living environment will be recovered and improved.
1.4.2Operating environment impact analysis conclusion
- Theanalysis conclusion of sewage pipes’influences on wastewater treatment plant

It is expected that the area sewerage volume will reach 12 million m3/d after the project is completed, no more than two sewage treatment plant design scale, and it will not have adverse effecton the normal operation of the sewage. At the same time,it also can improve the capacity of wastewater treatment and increase the sewage treatment plant economic, environmental, and social benefits.
- Environmental impact analysis conclusion of Ganhe,zhuohe and Migouhe.
After the completion of the project, the external pollution sources of these rivers will be eliminated , so will be the internal pollution sources. It will greatly changethe existing water pollution situation of these rivers.
- Environmental impact analysis conclusion of Xiaofuhe River.
After the completion of the project, the urban sewage pipe network system for Zhoucun will be perfect. The urban industrial wastewater and sewage will be transported to zhoucun Ganqing sewage treatment plant and Beijiao sewage treatment plant by the sewage pipe network. After treatment, the wastewater will be transported into Xiaofu River as it has reached the A standard 1st Class of “Urban sewage treatment plants standards for pollutants discharge”.There is no wastewater from the urban Zhoucun and the northern industrial park directly poured into Xiaofu River. This construction belongs to River sewage drain outletcomprehensive renovation plan of the middle and upper reaches of Zibo Xiaofuhe River. Afterwards, the water quality will be greatly improved.
- Management personnel activities affect analyzing conclusion
During the operation period, the management personnel in the project will produce a small number of sewage and garbage. The wastewater will be transported to Ganhe sewage treatment plant after the septic tank through the sewage pipe network. Household garbage will be collected by sanitation departments. The management personnel’s office activities have less impact on the environment.
- Air quality and the noise impact analysis conclusion
The implementation of the project bait-casting river will remove most of the river sediment pollution., and will governance pollution stench along the riverbanks. It will also improve the air quality of Zhoucun urban water basinto some extent. There will be no noise during the project, so there is no influence on environment of sound basically.
- Social environment impact analysis conclusion
