摘　　要：针对H市实施千岛湖引水后,优质原水水量远小于需水量的情况,提出了3种分质供水方案,即厨房用水与其他用水分质供水方案、生活用水与其他用水分质供水方案、工业用水与其他用水分质供水方案,并对3种方案进行了技术、经济比选。结果表明:在现有城市发展条件下,采用工业用水与其他用水分质供水方案一方面避免了优质水大量用于工业用水违背"优水优用"原则,另一方面避免了过度分质供水,造成的工程建设复杂,地下管位紧张等问题,大大减少了建设工程量。According to the situation that the high quality raw water quantity is far less than the water demand after the Qiandao Lake water diversion in H city,three kinds of water supply schemes are proposed,namely,the scheme of kitchen water and other water quality water supply,the scheme of domestic water and other water quality water supply,the industrial water and other water quality water supply schemes,and the technical and economic comparison of the three schemes is carried out.The results show that under the existing urban development conditions,the scheme of industrial water and other water quality water supply can avoid the high-quality water being used in large quantities in violation of the principle of"excellent water and superior use",on the other hand,it avoids the problems of excessive quality water supply,resulting in complex engineering construction and tight underground pipe position,which greatly reduces the construction quantity.
