Research On The Water Pollution Prevention Of Jinhua River Region Based On Environment Capacity Theory

With the overgrowth of the general economy of Jinhua City, the water pollution of Jinhua River has come into a big problem. Currently, how to prevent the Jinhua River from wastewater pollution discharged by industry and civil life is an exigent project for sustainable development of the economy of Jinhua River region. By investigating the current pollution state of Jinhua River, the reason led to the pollution is analyzed. By using the maths theory model, the elementary research of environmental capacity of Jinhua River's dominating wastes is given, which gives a strong support for the the pollution treatment of Jinhua River.The research of the thesis includes following contents:1,Investigation of the pollution resource of Jinhua River region and the analysis of the current environmentalThe testing data indicated that the major pollution factors of Jinhua River region were NH₃—N, fluorid, TP, organic wastes and eutrophication of the water. The region's pollution can be concluded to the following reasons: some industry enterprises discharge wastewater into the river frequently without proper treatment, the municipal wastewater treatment facilities can't be fit for the water environment protection, which leads to the large amount of domestic sewage be discharged directly, and the rural region pollution is a potential threaten to the Jinhua River region's environment.2,The related computation and analysis of water environmental capacityThe one-dimensional water quality model issued to simulate the relevant parameters of organic degradation, and calculate allow discharge capacity W as water environmental capacity E. The calculation results show that the pollution emissions of COD_cr,NH₃-N and TP of Jinhua River are beyond the allow carrying capacity of pollutants.3,The Jinhua River region water pollution remediation projectAccording to the computation result of water environmental capacity of Jinhua River region, river pollution remediation project is given. Such as accelerating the environmental pollution rectification of critical water pollution region; Focusing on rural non-point source pollution control; Carrying out the pollution remediation of key regulatory regions, sectors and enterprises; strengthening the propagandizing of environmental protection, Calling on the awareness of environmental protection in public, and so on.
