长江常州段饮用水源水质评价与建议
|
摘要
选取常州市饮用水源地部分水质监测数据为评价对象,采用水质指数法和改进的加拿大水质指数方程对监测数据进行了评价分析。指数法评价结果表明,2011年~2014年常州魏村水源地水质状况良好,水质类别总体上呈Ⅱ类水质,而2014年7月、11月、12月常州魏村水源地水质状况差,汞严重超标导致水质类别总体上呈V类水质。改进的加拿大水质指数法结果表明水质评价结果为中等,污染因子集中在总氮、镉、汞等指标,这提示了水源还存在包括由工业污染等造成的重金属污染的风险,需要进行污染源的排查,同时结合水厂的深度处理,保障出厂水水质的安全。还提出了加强水源地污染监控、保障水源安全等建议。
The water quality index method and the modified Canadian water quality index equation were used to assess the water quality of Changzhou drinking water source.It was shown that the water quality of the Changzhou Weicun drinking water source was in a good condition during 2011~2014 with water quality category Grade II by the water quality index method.While during June,July and November of 2014 the water quality of the Changzhou Weicun drinking water source was in a poor condition with the water quality category Grade V and the mercury concentration was extremely high and beyond the limit.However,the water quality was medium using the modified Canadian Water Quality Index method and the main pollution factors were total nitrogen,cadmium,mercury,etc.It was indicated that there exist risks of the heavy metal pollution in the drinking water source,which come from industrial pollution and should be investigated and treated further to protect the water safety.To enhance the pollution monitoring and controlling to protect the drinking water source were also suggested.
