摘　　要：随着工业化和城市化进程的加快,河流、湖泊、水库等接纳了大量各类污废水,污废水中的氮磷为藻类的生长和繁殖提供了大量的营养物质,使其富营养化程度日益加剧。为了有效去除水体中的藻类,目前自来水厂普遍采用絮凝法以达到高效经济除藻的目的。絮凝过程采用的混(絮)凝剂可分为:无机混凝剂、有机絮凝剂及复合絮凝剂。本文对絮凝除藻的作用机理以及各种常用的除藻絮凝剂研究进展进行了总结和评价,并展望了高效除藻絮凝剂的未来发展前景。with the acceleration of industrialization and urbanization,lakes and reservoirs have accepted a large number of industrial and domestic sewage,which provided a large amount of nutrients for the growth and reproduction of the algae,and made the eutroph-ication of natural water becoming more and more serious.In order to remove algae in the water body effectively,the flocculation method was widely adopted in water works to achieve the purpose of efficient economic removal of algae at present.In flocculation process,the general use of the flocculants could be divided into:inorganic coagulants,organic flocculants,and composite flocculants.In this paper,the commonly used flocculants and the flocculation mechanism for removing the algae were concluded and evaluated.Meanwhile,the prospects and the future development of flocculants for removing the algae were proposed.
