摘　　要：应对"水华"突发事件,最经济有效的方法之一是混凝沉淀除藻法,详细讨论了影响藻类混凝效果的因素,如混凝剂的种类、藻类生长周期、特性有机物(EOM、NOM)、预氧化作用等,通过对这些影响因素的研究,为提高藻类去除率和降低混凝剂的用量提供了参考,并且为藻类混凝去除方法的选择及开发提供一定的指导意义。Coagulation sedimentation process is one of the most economical and effective methods which can be used to respond to suddenly-occurred algae bloom.The factors that influence algae coagulation,such as： types of coagulants,growth phase of algae,characteristics of organic matters（EOM and NOM）,and preoxidation were discussed in detail.The results of the analysis not only provided references for algae removal enhancement and coagulant saving,but also offered some guidence to the selection and development of algae removal process.
