Technological Researchs On Comprehensive Environmental Prevention Of Mishan Reservoir

Many researches demonstrate that non-point pollution has become the primary restrictive factors in the improvement of water environment because of the effective control to point pollution. It is very important to analyze nonpoint source pollution rule and pollution control technology for ascertaining the water environment capacity, achieving the total amount control, establishing the projects to control reservoir pollution loads, anticipating the effect of non-point control technology.A Case Study of Mishan Reservoir was studied in this article. It introduced the AGNPS model which was the model of nonpoint source pollution simulation in common use. And the non-point pollution load of Mishan Reservoir that included TN & TP was simulated using the AGNPS model. The result indicated it can widely been used for analyses of the Mishan Reservoir. It also gained the nonpoint pollution load of TN & TP in Mishan Reservoir and spatial distribution of load of TN & TP.Meanwhile this paper used OECD model to calculate the water environment capacity of the Mishan Reservoir, the result indicated all environmental pollutants have overstepped the third standard. TN has overstepped the second standard. And reduced volume of COD & TN and TP was estimated if the water quality would be controlled in the second standard.According these productions, many measures to treat the pollution were brought forward. This paper can give the disciplinarian of nonpoint source pollution of Mishan Reservoir and reference for government to treat the pollution. It is important to improve the water quality, and it is beneficial to the studying of nonpoint pollution of Mishan Reservoir, over-nutrition and other analogical environment problem.
