城市水系统良性运作的节水减污技术关键

Key to water saving and pollution remediation technology for benign operation of urban water system

针对城市水质型水资源危机普遍存在的现象,通过对城市水系统运作现状问题及影响因素的分析,从"节水减污"的角度,就城市需水量预测、供水技术、污水回用与雨水利用等方面,探讨了城市水系统良性运作的关键技术,提出了管理技术的两点意见。

In consideration of the water quality-induced water resources crisis generally existing in China, an analysis is made of some problems in current urban water system and some affecting factors. From the angle of water saving and pollution remediation, key techniques in the aspects of water demand prediction, water supply, wastewater reuse, and rainwater utilization are discussed for benign operation of the urban water system. Besides, two ideas on the water system management are put forward.
