太原市利用污水回用防治地面沉降的探索

Preventing land subsidence by wastewater reuse in Taiyuan

介绍了地面沉降的危害,提出了污水经过处理后用于防治地面沉降的新思路,主要包括两种方法:一是将处理后的污水回灌地下补给地下水;二是用处理后的污水回用代替部分自来水,减少地下水的开采量,以控制地面沉降。

This article introduced the danger of the land subsidence, and existing preventive measure, put forward new idea that wastewater was reused for preventing land subsidence. The idea includes two kinds of methods： First is supplying the ground water, namely the sewage treated is rejected to replenish the groundwater; and second is reducing the exploitation of the groundwater namely sewage treated reuse to replace some tap water, so it can reduce the extraction of the groundwater.
