摘　　要：综述了壳聚糖、淀粉、纤维素、木质素等天然高分子絮凝剂的改性及其在印染废水处理中的应用。与纯天然高分子絮凝剂相比,改性天然高分子絮凝剂对印染废水的絮凝效果得到明显提升。另外,将天然高分子絮凝剂与无机小分子絮凝剂、无机高分子絮凝剂或有机人工合成高分子絮凝剂复配,制备出相应的复合型高分子絮凝剂,也在处理印染废水时表现出了较为优异的性能。The modification of natural polymer flocculants, such as chitosan, starch, cellulose and lignin,as well as their application in treatment of printing and dyeing wastewater were reviewed. Compared with pure natural polymer flocculants, the modified natural polymer flocculants showed improved flocculation performances in treatment of printing and dyeing wastewater. In addition, the compound flocculants, which were prepared by mixing of natural polymer flocculants with inorganic small molecule flocculants, inorganic polymer flocculants or organic synthetic polymer flocculants, also showed excellent performance in treatment of printing and dyeing wastewater.
