摘　　要：选取水体富营养化中最为常见、难去除、危害大的铜绿微囊藻为除藻处理对象,研究了以天然高分子淀粉通过丙烯酰胺与二甲基二烯丙基氯化铵接枝共聚改性,制备除藻絮凝剂,研究其对铜绿微囊藻除藻效果.实验结果表明,淀粉接枝共聚物对含藻水体有较好的治理效果,并初步分析了淀粉接枝共聚物对藻细胞的絮凝机理.Microcystis aeruginosa is the most common, harmful variety algae in the eutrophic water and hard to remove. In this paper, Starch-Acrylamide-Dimethyl Diallyl Ammonium Chloride graft copolymer is synthesized. It shows good capability of removing the algae cells. According to the results, the flocculation mechanism of the graft eopolymer is discussed.
