摘要
为加强常州市集中式饮用水水源地保护与管理,本文评价了常州市的长江魏村、天目湖等6处集中式饮用水水源地2020年的水质现状及2011—2020年的水质变化情况,重点分析了长江两处水源地粪大肠菌群、铁含量超标现象及长荡湖涑渎水源地总磷超标原因。结果表明,常州市集中式饮用水水源地水质状况总体良好,长江水源地存在铁含量超标、偶见粪大肠菌群污染现象,长荡湖水源地近年来总磷浓度较高。针对常州市集中式饮用水水源地存在的问题,提出合理的水质改善和水源地保护对策。
In order to strengthen the protection and management of centralized drinking water sources in Changzhou,this paper evaluated the water quality status in 2020 and the water quality changes in 2011-2020 of 6 centralized drinking water sources in Changzhou,such as the Yangtze River Weicun water source and Tianmuhu Lake water source.This paper focused on the analysis of fecal coliform,the phenomenon of iron content exceeding the standard in two water sources in the Yangtze River and the reasons of total phosphorus exceeding the standard in the Changdanghu Lake Sudu water source.At present,the water quality of centralized drinking water sources in Changzhou is generally good,the iron content in Yangtze River water sources exceeds the standard,and fecal coliform pollution occasionally occurs.The total phosphorus concentration in Changdang Lake water sources is high in recent years.In view of the problems existing in centralized drinking water sources in Changzhou,this paper puts forward reasonable countermeasures for improving water quality and protecting water sources.
