英文摘要：

Types of bioflocculant, chemical ingredients and the methods of constituent analysis commonly used in laboratory were described in this article. It also summarized factors of affecting the biofloeeulant production and the flocculating activity and their floccular mechanism. It detailed introduced some newly application situation in the current water treatment. Some prospects of the microbial flocculants for the development were proposed including screening of a floeculant-producing strain with high and stable flocculating activity, studying on compound bioflocculant and combination of bioflocculant and traditional flocculants, selecting the cheaper substitution culture medium, improving methods of purification of bioflocculant and so on. These new directions made the main forecast on the bioflocculant research area.
