Abstract


Dilute the self-purification capacity as a water storage of the Three Gorges Reservoir , the water in the reservoir area weakened water environmental capacity will be reduced , if not take active preventive measures , pollution will exacerbate the reservoir area . Yulin River is one of the larger secondary rivers located in the Three Gorges Reservoir Area , according to the Three Gorges Reservoir and its upstream water pollution prevention plan (2001-2010 requirements , Yulin River for the protection of the water body water quality , water environment pollution control in this study through the evaluation of pollution load and water quality status of Yulin River obtained : Yulin River pollution comes mainly from two aspects of agriculture, water and soil in the township sewage basin point source pollution and watershed the loss caused by the non-point source pollution ; such as not Yulin River pollution be governance , the planning year Yulin water quality will not be able to meet the water quality requirements of the water environment function zones the study by water quality modeling , calculation the Yulin River basin water Environmental Capacity planning the level years Yulin River pollution load reductions , the concept of water environmental capacity value and its calculation method , and used in the the Yulin River basin water Environment management through the Yulin River town sewage plant sewage treatment process optimization , proposed for Yulin optimize the process of the watershed urban sewage plant , and compared with the recommended process and planning ; the opposite source pollution prevention measures of ; from watershed systems engineering angle of view , the Yulin River water environmental management measures and recommendations .
