集中污水处理厂尾水再生回用的技术与经济分析

Technical and Economic Analysis of Reclaimed Water Reuse in Municipal Sewage Plant

在对常州市各类污水处理厂尾水水质和水量分析基础上,根据不同行业用户给水规模与水质需求,提出了不同污水处理厂—特征用户的再生水深度处理方案,着重分析了各类方案的技术经济可行性,提出了应从多源取水、分质供水、分类处理入手,从给排水一体化角度来合理建设城市集中污水处理厂中水回用系统。

Based on the analysis of the quality and quantity of tail water in different kinds of wastewatertreatment plants in Changzhou, the authors put forward the raw-water advanced treatment schemes be- tween plants and reclaimed water users with multiple requirements. The technical and economic feasibility of the different schemes emphatically analyzed. The research shows that what should be applied is the in- tegration of water supply and drainage in multi-source, grade water supply and wastewater treatment to plan reclaimed water reuse system reasonably.
