关于污水回用与城区规划相结合的探讨

Discussing on the Combination of Wastewater Reuse and the Layout of City Zone

引用实例分析了我国污水回用现状及存在的问题,即采用建筑中水系统形式,由于处理水量过小,造成投资和运行费用相对较高,回用水在价格上没有优势,提出在我国应提倡污水回用与城区规划相结合,充分利用污水处理的规模效应来降低投资和运行成本,以及避免建设城市回用水系统出现的投资回收年限长等问题并分析了污水回用与城区规划结合后,在投资、运行、管理等方面的综合效益。

It is analyzed the situation and problems of wastewater reuse in China, that is the main method of wastewater reuse—gray water, with small scale, lead to high cost. It is put forward that the wastewater reuse should be combined to the layout of city zone, so as to utilize the scale effect of wastewater treatment to reduce the investment and the cost, and to avoid taking a long time to withdraw the investment when constructing the pipe system of wastewater reuse in a whole city.
