多糖类天然高分子絮凝剂在污泥处理中的应用

摘要

多糖类天然高分子具有原料丰富、无毒、易于生物降解等特点，在水处理方面的研究与应用日益广泛。综述了近年来淀粉类、纤维素类及壳聚糖类等天然多糖高分子在污泥调理、脱水等方面的应用新进展。%Starch, cellulose and chitosan are polysaccharides from natural polymers, which are readily available, nonpoisonous and biodegradable. They are used in wastewater treatment increasingly and new methods and techniques have been developed. In this paper, the application and development of polysaccharides and its derivatives in treating sewage sludge are discussed.
