摘要
[目的]分析不同水源水和水处理工艺对上海市生活饮用水水质的影响,为采取针对性的监管措施提供依据。[方法]选择5个区,于2012年分别采集上海市5个行政区的水源水样23件、出厂水样115件、管网水样672件进行检测。[结果]不同水源、水处理工艺的出厂水和管网水合格率有明显差异,以水质最好的青草沙水库为水源的出厂水和管网水合格率最高,采用深度水处理工艺的出厂水和管网水耗氧量合格率较一般水处理工艺的高。[结论]要改善上海市饮水水质,应从选择优质水源和有效的水处理工艺入手。
[ Objective ] To analyze the impact of different water sources and water treatment processes on drinking water quality in Shanghai in order to make appropriate regulatory measures. [ Methods ] Five districts of Shanghai were selected and 23 source water samples, 115 finished water samples, 672 tap water samples were tested in 2012. [ Results ] The qualified rates of finished and tap water with different sources and water treatment processes were statistically different. The finished and tap water samples with the highest quality were from Qingcaosha reservoir. The qualified rates of oxygen consumption in the finished water and tap water samples using deep water treatment process were higher than those using traditional process. [ Conclusion ] Good water sources and water treatment processes are required to improve the quality of drinking water in Shanghai.
