摘要
利用1993—2008年的统计数据,分析了我国城市供水的总体发展状况,并从水源、净水工艺、输配水管网、二次供水等方面考察了我国城市供水系统的特征,认为我国城市供水能力显著提高,供水和用水总量趋向稳定,人均综合用水量下降,城市生活用水成为城市供水的主要对象。但是城市依然面临着水资源短缺和水源污染的严峻形势,迫切需要在水源保护、净水工艺、管网改造、二次供水管理等方面有所作为,总结并提出我国城市供水系统进一步发展的政策建议。
The overall development of the urban water supply was illustrated by 1993—2000 statistical data,and the development features of urban water supply system were described from water source,water treatment,water distribution system and secondary water supply.According to analysis,water supply capacity was enhanced significantly.The total water supply and consumption would level off in the future,per capita water consumption declines,and water for city′s residential use took the maximum water consumption.But cities were still facing the sever situation of water shortage and pollution,and some measures should be taken urgently to solve problems of water source protection,water treatment,network reform and secondary water supply management.The summaries and policies of further development of urban water supply system were presented in the end.
