Abstract: Because of its efficient flocculation effect and non-toxic properties, compound bioflocculant(CBF) has become one of the popular microbial water treatment agents at home and abroad in recent years. The research background and characteristics of CBF were introduced. And the research and application of CBF were reviewed, including screening of strains, optimization of cultivation conditions of flocculant-producing bacterium, selection of cheap substrate, components analysis of CBF, the flocculation mechanism, engineering application of CBF in water pollution control. Further refers to the problems existing in the research work of today’s composite bioflocculants, and prospects for future research and development.
Key words: compound bioflocculant; flocculation mechanism; optimization; waste water; development trend
引言
微生物絮凝剂是一类微生物代谢产物，主要成分有糖蛋白、多糖、蛋白质和DNA等，利用微生物技术，由微生物发酵和提取而成，是一种无毒、无二次污染的高效新型水处理剂[1-7]。微生物絮凝剂的研究始于20世纪
50年代，日本学者Nakamura等[8]首次发现微生物培养液具有絮凝作用，掀起了微生物絮凝剂的研究热潮。就微生物絮凝剂的研究而言，一直以来主要集中在絮凝菌分离、鉴定及筛选，絮凝剂处理废水的实验室小试阶段。具有生产成本高、絮凝过程及机理阐述不清等问题。近年来，为了提
