摘要
为了研究天津市主要排污河流的水质污染情况,利用综合评价法对天津市的5条主要排污河流:津河、南运河、海河、北运河、子牙河2009年12个月的水质监测数据进行了监测和评价。结果表明:从单项污染指数来看,海河的污染指数总磷>氨氮>总氮>化学需氧量>氟化物>1,说明海河的富营养化比较严重;海河的综合污染指数为12.15最高,津河和南运河的综合污染指数较低分别为2.76和2.37;污染分担率方面看,海河的总氮污染分担率也较高,达到了16.62%。最终水质污染程度(P)分析表明,海河P>0.5属于中度污染,其他4条河流P<0.5属于轻度污染。
In order to study the situation of the Tianjin main blowdown rivers＇water contamination,we used comprehensive evaluation method to evaluate the water quality of five main blowdown rivers in Tianjin,Jinhe River,South Canal,Haihe River,North canal and Ziya River.In 2009,we processed the monitoring and evaluation for water quality data.The results showed that：judging from single pollution index,Haihe Rivers＇pollution index was in the order of total phosphorusammonia nitrogentotal nitrogenchemical oxygen demandfluoride1,indicating that the eutrophication in Haihe Rivers was severe;The comprehensive pollution index of Haihe River was 12.15,which indices in Jin River and South canal were lower 2.76 and 2.37,respectively than in Haihe River,the rate of pollution contribution,the total nitrogen of Haihe River was 16.62%.Finally water pollution degree（P） analysis shows that,P〉0.5 in Haihe River belongs to moderate pollution and P〈0.5 in other four rivers belongs to light pollution.
