Abstract：胞外多聚物( Extracellular polymeric substances,EPS)是废水生物处理系统中生物聚集体(包括絮体污泥、生物膜、颗粒污泥等)的重要组成部分,直接包裹于微生物细胞壁外,其理化性质及所处的特殊位置决定了它在生物聚集体中的重要作用.综述了EPS对废水生物处理系统污泥沉降性能、脱水性以及膜生物反应器膜污染影响的相关研究,分析认为EPS组成与结构特性改变污泥表面电位、疏水性等,进而影响污泥沉降与脱水性能、膜污染程度；以好氧颗粒污泥为典型的生物聚集体代表,总结了EPS组分含量与分布对颗粒污泥的形成与结构稳定性的影响,并在EPS提取方法标准化、现代理化技术与分子生物学技术综合分析等方面进行了展望,进一步的研究有望揭示生物絮凝体形成过程EPS的产生与调控机制.
