介绍了发达国家污水处理与利用的新进展.分析了我国水环境面临的严峻现实及污水处理与利用中存在的问题;指出污水深度处理与回用、形成水的健康良性循环是保护与恢复城市水环境的有效途径;认为城市污水处理与利用规划设计要打破传统设计规则,合理划分排水分区,充分考虑再生水回用,科学地确定污水厂厂址与数量,选择适合我国各地实情的工艺流程,优先选用合格的国产污水处理设备,预留污水厂分期发展的空间,新建城市道路应预敷再生水回用管线.以珠江三角洲开发区为例,探讨了城市新区污水系统的设计原则.参21.

Research on Countermeasures of Urban Wastewater Treatment and Utilization in China

The new advance on wastewater treatment and utilization in developed countries were introduced and discussed. Analysis of water pollution was carried out in China. By analyzing existing problems of wastewater treatment and utilization in China,authors pointed out that advanced treatment and reuse of wastewater,healthy water cycling are effective approaches of water condition protection. New ideas and methods about wastewater treatment and utilization were put forward as follows:Planning the proper scope of drainage nets;Deciding numbers and addresses of wastewater treatment plants exactly to make wastewater reuse expediently;Selecting suitable treatment train according to the characteristic of every city;Adopting domestic wastewater treatment facilities first;Leaving developing space of wastewater treatment plant and reuse pipelines. Design experience of wastewater treatment system of the Pearl River Delta was summed up.21refs.
