近年来,很多城市大量抽取地下水造成城市地面沉降问题。城市中水回收再利用是解决城市缺水的有效途径之一,对提高水资源利用率具有重要意义。特别是国家大力推广的海绵城市设计和综合管廊建设把中水回收利用推向了高潮。本文分析了城市中水回收再利用技术的意义、常见的处理方法以及中水回收再利用技术在海绵城市设计和综合管廊建设新领域中的应用。
In recent years, many cities have drained groundwater to cause urban land subsidence problems. Recycling of reclaimed water in urban areas is one of the effective ways to solve the problem of urban water shortage, which is of great significance to improving the utilization of water resources. In particular, the sponge city design and integrated pipe gallery promoted by the state have pushed the reclamation of reclaimed water to a climax. This paper analyzes the significance of city water recycling technology, common treatment methods and the application of reclaimed water reclamation technology in the new area of sponge city design and integrated pipe gallery construction.
