改用其它水质进行城市道路保洁的探讨

An Probe into “Change Water” for Urban Road Cleaning

提出改用生活污水取代自来水 (以下简称为改水 )进行城市道路保洁 ,“改水”方案分析显示 ,直接供水方式可作为近期“改水”道路保洁阶段性措施。中水 (生活杂用水 )道管网供水方式可作为中远期建设目标 ,不仅可作道路保洁 ,而且还可作其它用途 。

This paper suggests using daily living waste water to replace tap water for cleaning of Urban roads. Preliminary“change water”schemes and their comparison analysis suggests. That direct waste water supply may be considered as a transitional phase of “change water” for road cleaning in the near future. Intermediate water piping network supply is the direction of water supply towards different water quality for different use, and may be regarded as the development object of medium and distant future. This intermediate water, not only for road cleaning but also for other uses, is an important way to achieve non-drinking water supply.
