Project Feasibility Research Of Sewage Treatment In Sanmenxia Industrial Agglomeration Area

In the context of the economic and social development, the industrial wastewater impacton ecological environment becomes more and more obvious. Especially in the industrialconcentration area, the industrial wastewater directly contaminates the water of agglomerationarea, causing serious pollution, which serious influences the local sanitation and people’shealth seriously. Disposing of sewage and constructing industrial agglomeration area sewagetreatment plant do a lot to the overall environment and the image of a city, and also plays alarge role on the economic and social sustainable development of the concentrated area.Sewage treatment engineering is an important infrastructure of a city, which is an importantpart of protecting the city environment. It needs a lot of investment to construct it. In order toavoid blind investment，achieve the scientific decision-making and also be responsible for thepresent and future generations, it is necessary to research and analysis the project feasibility ofthe sewage treatment. This study aims at sanmenxia industrial concentration area with mixedwastewater. On the basis of the analysis of the wastewater quality and quantity, according tothe demand of local economic development level and processing of several major domesticsewage treatment technique, it determines the optimal processing scheme by comparison.Through the comparative study, the subject of wastewater treatment process uses the “A2/O-SBR+biological filter”, the level of A standard, namely the BOD5≤10mg/l，CODcr≤50mg/l，NH3≤5mg/l，TP≤0.5mg/l. The effluent from the sewage treatment plant will bereused and the sludge dewatering can be carried to the landfill used for sanitary landfill. Theconstruction of the project can thoroughly improve the environmental pollution problem ofthe industrial concentration area and the surrounding area, and ensure the implementation ofthe green ecological industrial agglomeration area environment and create a good investmentenvironment. At the same time, the construction and operation of the project will also bringhuge economic benefits and social benefits.
