水源污染使我国众多城市供水水质受到影响。国内许多城市小区采用分质供水愈来愈多 ,小区分质供水是适合我国国情的一种过渡办法。“打开水笼头 ,喝纯净水”是城市未来的目标。而采用城市整体分质供水在技术、经济及诸多方面困难很多 ,负面影响很大 ,应慎重采用。 Water pollution has affected the water quality of many cities in our country. In many domestic cities, more and more sub-quality water supply is adopted. Sub-quality water supply in residential areas is a transitional approach suited to China’s national conditions. “Opening a Halter and Drinking Purified Water” is the city’s future goal. However, using the overall quality of water supply in urban areas is much more difficult in technology, economy and many other aspects, with a huge negative impact and should be adopted with caution.
