摘　　要：选择性絮凝现有方法的分类可从吸附角度和动力角度两个大方面考虑。着重介绍从吸附角度考虑的增减颗粒上的活性质点数的方法,它包括选择合适的絮凝剂官能团、改变颗粒表面电位法、使用选择性分散剂法和近年来开发的SBA(质点阻塞剂)法等一些常用的方法。也对选择性絮凝方法的机理和分类规律进行了阐述。In the view of adsorption and driving force, the selective flocculation method has been classified according to their characters. The method of increasing or decreasing active sites of particles was mainly introduced in the view of adsorption. The method includes choosing suitable functional group of flocculants, altering surface potential of particles, and using selective dispersants and site blocking agents (SBA), etc. The mechanism and principle of the selective flocculation was also summarized.
