[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 influence of different water sources and water treatment processes on the quality of life drinking water in Shanghai, and provide the basis for taking targeted regulatory measures. [Method] Five districts were selected. In 2012, 23 water samples were collected from 5 administrative districts in Shanghai, 115 water samples were delivered from factory and 672 water samples from pipe network were tested. [Result] There was a significant difference between the qualified rates of water supply and pipe network in different water sources and water treatment processes. The highest passing rate of water and pipe network with the highest water quality of Qingcaosha Reservoir was the highest passing rate, and the factory with advanced water treatment process Water and pipe network water oxygen pass rate higher than the average water treatment process. [Conclusion] To improve the quality of drinking water in Shanghai, we should start with selecting high quality water sources and effective water treatment process.
