Shahe Reservoir Eutrophication causes and trend analysis

近年来沙河水库原水高锰酸盐指数、总磷、氨氮等超标,水质趋向恶化,出现富营养化,已严重威胁供水安全。通过对污染成因分析,提出了解决面源污染要从改变农业耕作方式入手来控制污染源,才能遏制水体富营养化的趋势。

In recent years,the portion of permanganate index,total phosphorus,and ammonia nitrogen in Shahe reservoir is excessive,so water quality is deteriorated and shows the water is eutrophication,and has been a serious threat to water supply.Through the analysis of causes of pollution,it puts forward to solve non-point source pollution,changes in agricultural practices from the start to control the sources of pollution in order to control the trend of eutrophication.
