胞外聚合物(EPS)对市政污泥性质影响的研究进展

Research Progress on Extracellular Polymeric Substances and Its Role on Municipal Sludge Properties

污泥中的胞外聚合物是其重要的组成部分,文章对胞外聚合物的化学组成及结构的最新进展进行了介绍;论述了胞外聚合物中的粘液层(slime层)、松散结合层(LB-EPS层)和紧密结合层(TB-EPS)对污泥絮凝、沉降以及脱水所产生的影响。

Based on latest literatures, this paper summarizes the chemical composition and structures of EPS on municipal activated sludge properties; The Slime, Loosely bound EPS and Tightly bound EPS play an important role in sewage sludge disposal to sludge flocculation, sludge settleability and sludge dewaterability.
