摘要
阐述了原水供水的意义。分析了上海市饮用水水源地、原水供水及自来水厂的现状，以及上海市饮用水水源地和原水供水的关系，并讨论了饮水安全问题。结果表明，截至2008年6月，上海市原水工程取水能力为909．637万m^3／d，占全市公共供水日取水总量的82．8％；原水供水工程所取水的水质属于II、III类水，优于分散式供水取水的河流水质。指出原水供水有利于提高供水水质，有利于保证供水安全，对上海市公共供水有着决定性意义。
Drinking water safety issues are closely related to people＇s life and health. Present situations of the drinking water sources, raw water feeding and waterworks in Shanghai were analysed, as well as the relationship between the drinking water sources and raw water feeding. Regarding centralised raw water facilities in Shanghai, the water intake capacity was 9 096 300 cubic metres per day by June 2008, accounting for 82.8% of the water withdrawal for public water supply of the whole city, and quality of the abstracted water was in Category II or III, better than that of the waterways from which scattered water supply systems were taking in. tt has revealed that a centralised raw water feeding system is of great significance in improving quality and ensuring security of the water supply in Shanghai.
