摘要
微生物絮凝剂是一类新的天然高分子有机絮凝剂,它具有无毒、高效、无二次污染、来源广泛等特点。介绍了微生物絮凝剂的主要组成成分、来源、作用机理,以及相比较于普通絮凝剂的优势。分析了在生物絮凝剂处理煤泥水上,絮凝微生物、影响因素、作用机理以及微生物育种的研究现状,而影响因素包括以下几个方面:煤泥水pH值、絮凝剂投加量、金属离子、微生物培养时间。并对其今后在煤泥水处理的发展方向,及怎样走向工业化应用提出了一些建议。
Bio - flocculants is a kind of new natural organic polymer flocculants. Its characteristics includes non - toxic, high efficiency, no second pollution, etc.. This paper describes the main components, resource, reaction mechanism and advantages compared with ordinary coagulants. The current research status of flocculating microbial, influencing factors, mechanism and microbial breeding by biological flocculants to treat slime water was described. The influencing factors include pH of slime water, flocculants dosage, metal ion and microbial culture time. Some advises on the application of bio - flocculants in slime water treatment were presented.
