微生物絮凝剂的研究与应用

Investigation and Application of Microbial Flocculant

絮凝沉降法是目前国内外用来提高水质处理效率的一种既经济又简便的水处理方法,絮凝剂是絮凝沉降法的核心;而微生物絮凝剂则是利用生物技术,通过微生物发酵抽提精制得到的一类沉降效率高、生物降解性好、使用范围广的新型絮凝剂。本文概述了微生物絮凝剂的研究现状,介绍了微生物絮凝剂的种类,分析了微生物絮凝剂的絮凝作用机理及其在水处理中的应用,展望了微生物絮凝剂的发展趋势。

Flocculation settlement method is an economical simple water treatment method which is used to improve water treatment efficiency in home and abroad, and the flocculant is the core of flocculation settlement method. Microbial flocculant is a new type of flocculant of high settlement efficiency, good biodegradability, and wide application, which is gained through microbial fermentation and extraction by biotechnology. This paper summarized the investigation progress of microbial flocculant, introduced the species of microbial flocculant, analyzed the flocculating mechanism and the application in water treatment. At last the development trend of microbial flocculant was forecasted.
