摘　　要：开发新的混凝剂或采用不同混凝剂的组合工艺强化混凝效果,是《城市供水水质标准》(CJ/T 206—2005)出台后许多现有老水厂面临的新问题。为此,对国内外的混凝理论及混凝剂的开发、应用现状进行了系统分析,提出了微生物絮凝剂的提取、混凝剂之间的协同效应以及利用分形理论建立混凝模型是今后混凝理论研究及混凝剂的开发方向。Development of new coagulants or combination of various coagulants to enhance the coagulation process is a new problem faced by many present water treatment plants after implementation of the Water Quality Standards for Urban Water Supply （ CJ/T 206 - 2005 ）. Therefore, the coagulation theory, coagulant development and application status at home and abroad were analyzed systematically. It was brought forward that extraction of bio-coagulants, co-coagulation of combined coagulants and coagulation models based on the typing theory would be the trend of coagulation theory and coagulant development in the future.
