摘　　要：针对传统无机絮凝剂如铝、铁盐存在使用量大,絮凝效果一般,而有机絮凝剂如聚丙烯酰胺存在二次污染等问题,文章概述了高分子复合絮凝剂处理不同类型废水的研究现状,介绍了不同复合絮凝体系的絮凝机制,包括无机-无机、无机-有机、有机-有机和微生物等复合絮凝剂,及其在废水处理过程中的应用发展过程。并从絮凝性能、絮体特性、污泥脱水3个方面阐述了单一絮凝体系的局限性和挑战,提出了添加功能性成分的应对策略,最后展望了絮凝剂的发展前景,为新型复合絮凝剂的设计和开发提供参考。In response to the problems of traditional inorganic flocculants such as aluminum and iron salts with large dosage and poor flocculation effect,and organic flocculants such as polyacrylamide with secondary pollution,etc.The current research status of polymeric composite flocculants for treating different types of wastewaters was summarized,and the flocculation mechanisms of different composite systems,including inorganic-inorganic,inorganic-organic,organic-organic and microbial composite flocculants,with their application development process in the wastewater treatment were introduced.The limitations and challenges of single flocculation systems were also clarified in terms of flocculation performance,floc properties and sludge dewatering,and the solution strategies of adding functional components was proposed.Finally,the development prospect of flocculants was prospected to provide reference for the design and development of new composite flocculants.
