太原杏花岭区地表水环境现状及评价

Status and evaluation of water environment in Taiyuan city

基于该地区的汾河水利项目,分析各种污染物浓度在水中的变化趋势,调查造成杏花岭区主要水质污染的原因,利用单因子污染指数法,将水环境的污染状况做出评估,结果显示:杏花岭区汾河的水质主要污染指标为COD,污染指数均值达4.14,汾河污染情况比较严重,水质较差主要是由于工业污染造成的;龙潭湖主要污染物是COD,污染指数为1.59,由此看来龙潭湖水环境情况污染较小。

Based on the Fenhe water conservancy project in the area,the changing trends of various pollutant concentrations in water were analyzed,the causes of major water quality pollution in the Xinghualing area were investigated,and the pollution status of the water environment was assessed using the single-factor pollution index method.The results show that the main pollution index of Fenhe river in Xinghualing district is COD,and the average pollution index reaches 4.14.The pollution situation of Fenhe river is relatively serious,and the poor water quality is mainly caused by industrial pollution.The main pollutant in Longtan lake is COD,and the pollution index is 1.59.It seems that the water environment of Longtan Lake is less polluted.
