摘　　要：天然高分子絮凝剂因其本身具有絮凝性,无毒,可生物降解,在水处理中具有广泛的应用前景。但因其不带电且溶解性差,造成其絮凝效果不理想,需通过改性,如醚化、接枝共聚等,在其分子链上引入各种官能团以改善其絮凝效果或改善其带电性、吸附性和杀菌性等。本文对目前常见的淀粉基、壳聚糖基、纤维素基和木质素基等天然高分子基改性絮凝剂,按不同改性方式进行分类概述,综述了近年来国内外改性天然高分子基絮凝剂的研究进展。同时还简单阐述了天然高分子基絮凝剂制备过程并对天然高分子基絮凝剂的研究方向进行了展望。Natural polymer flocculant has an extensive application prospect in water treatment because of its flocculation,non-toxicity and biodegradability.However,its flocculation effect is not ideal due to the lack of charge and poor solubility.It needs to be modified,such as etherification,graft copolymerization and so on.Various functional groups are introduced into its molecular chain to improve its flocculation or its charge,adsorption and sterilization.This paper summarizes the usual natural polymer based modified flocculants such as starch,chitosan,cellulose and lignin according to different modification methods,and summarizes the research progress of modified natural polymer based flocculants in China and abroad in recent years.At the same time,the preparation process of natural polymer based flocculant is briefly described,and the research direction of natural polymer based flocculant is prospected.
