摘要 介绍了胞外聚合物的产生和组成(多聚糖,蛋白质,少量DNA,脂和腐质酸等);胞外聚合物在污泥处理系统中对污泥的絮凝性能、沉降性能、脱水性能及重金属吸附性能的影响;以及胞外聚合物本身的生物降解性。胞外聚合物在废水生物处理中发挥着重要作用。 Based on review of literatures,this paper summarizes the effects of EPS on activated sludge properties such as flocculation,settleability,dewaterability as well as adsorption of heavy metals.Biodegradability of EPS is also discussed.
