Present Status and Development Trend of Studies on Microbial Flocculants

相对于传统絮凝剂而言,微生物絮凝剂具有絮凝效果好、应用范围广、易生物降解、对环境安全、无二次污染的特点。文章综述了微生物絮凝剂的种类、微生物絮凝剂的絮凝机理研究现状、微生物絮凝剂的发酵生产以及微生物絮凝剂在水污染控制方面的应用,并对复合型微生物絮凝剂的特点、发酵工艺、应用前景进行了介绍。在此基础上,分析了目前微生物絮凝剂研究工作中存在的问题,提出今后微生物絮凝剂研究的主要发展趋势。

Compared with the traditional flocculants,microbial flocculant has advantages of high removal efficiency,wide applicability,good biodegradability,safety for environment and no secondary pollution. In this paper,the types of microbial flocculants,flocculating mechanism of microbial flocculants,fermentation of microbial flocculants and their application in water pollution control are reviewed. The characteristics of compound microbial flocculants,their fermentation technology and application are introduced. Based on this,the problems that exist in the current research on microbial flocculants are analyzed,and the main development trend of research on microbial flocculants is put forward.
