摘要
目的通过对青草沙水库启用后上海市浦西地区饮用水水质的分析研究,了解青草沙水库启用对上海市饮用水水质的影响。方法分别于青草沙水库建成前(2009—2010年)、后[2011—2012年(水源水为2011年)],对上海浦西全部7个区的甲、乙、丙3家水厂的水源水、出厂水和129个监测点的二次供水及152个监测点的末梢水水样进行采集和检测。结果青草沙水库启用后,饮用水指标合格率和样品合格率显著上升,除铝外,其他指标的检测均值显著下降。结论青草沙水库的启用显著改善了上海市浦西7区的饮用水水质,但需要关注含铝混凝剂的使用。
Objective To understand the influence of Qingcaosha reservoir operation on drinking water quality in Puxi area,Shanghai. Methods Before（2009-2010） and after（2011-2012,the water source was replaced in 2011） the Qingcaosha reservoir operation,the samples from raw water and finished water of three water plants as well as 129 sampling points of secondary water supplies and 152 sampling points of tap water were collected and tested in all seven districts of Puxi,Shanghai. Results The qualified rates of samples and indicators increased and the detection values decreased significantly except aluminum after the Qingcaosha reservoir operatioin. Conclusion The drinking water quality of seven districts in Puxi,Shanghai has been remarkably improved since the operation of Qingcaosha reservoir, but more attention should still be paid to the use of aluminum coagulants in the future.
