结合“引温济潮”工程的实施,对受水区地表水的监测显示现状水体为富营养状态,有机物污染较为严重。根据研究区污染物负荷的调查,潮白河顺义城区段水环境主要污染源是非点源污染,其产生的主要污染物全年排放量分别为CODCr 213.29 t、总氮80.21 t、总磷9.98 t,按照贡献大小排序为农田径流>农村生活污水>城区径流。根据潮白河顺义段水环境污染成因分析,笔者提出了非点源污染防治控制的对策和建议。
In combination with the implementation of the “Wen Wen Chao” project, the monitoring of the surface water in the receiving area shows that the water body is in an eutrophic state and the pollution of organic matter is serious. According to the investigation of pollutant load in the study area, the main pollution source of water environment in Shunyi City is Chaobai River non-point source pollution. The annual discharge of major pollutants is 213.29 t CODCr, 80.21 t total nitrogen and 9.98 t total phosphorus, Contributions ranked in the order of farmland runoff> rural domestic sewage> urban runoff. According to the analysis of the causes of water pollution in Shunyi section of Chaobai River, the author puts forward the countermeasures and suggestions on prevention and control of non-point source pollution.
