摘要
为全面了解北京市大兴区长子营镇水环境的污染源,对镇域点和面污染源进行了调查,采用产排污系数法和面源产物系数法等方法对污染物排放量进行了核算。结果表明,污染物排放量按源头由大到小为:养殖业污染>生活污染源>农业面源污染。长子营镇水环境污染源以畜禽养殖业为主,污染物产生量占总产生量的90%以上。针对上述现状提出相应的保护水环境的防治措施建议。
In order to comprehensively understand the pollution sources of the water environment in the Zhangziying Town,Daxing District,Beijing,the pollution sources of the town and the surface pollution were investigated.The pollutant emissions were calculated by the method of production coefficient and the coefficient of surface source factor.The results showed that the order of pollutant emissions in terms of the sources from large to small was:livestock and poultry breeding source>sewage source>agricultural non-point source.The water pollution sources of the town were dominated by livestock and poultry breeding,and the amount of pollutants produced was more than90%of the total production.Suggestions on protecting water environment in view of the present situation were proposed.
