废水生物处理中胞外聚合物(EPS)的研究进展

摘要

胞外聚合物(Extracellular Polymeric Substances,EPS)在废水生物处理中发挥着重要作用.将近年来国内外对EPS组成成分、结构、理化性质、提取方法等方面的研究进行了归纳,总结了EPS在废水生物处理领域中如膜污染、污泥特性、生物除磷和重金属吸附性能等方面的研究进展.%Extracellular polymeric substances (EPS) plays an important role in biological wastewater treatment. Theresearches in recent years on the components,structure,physical and chemical properties of EPS,both in China andabroad,are reviewed. The research progress of EPS applied to biological wastewater treatment fields,such asmembrane pollution, sludge characteristics, biological dephosphorization and heavy metal adsorption capacities, issummarized.
