摘要
结合国内外微生物絮凝剂及其产生菌的研究概况,分析了微生物絮凝剂的化学组成和属性,探讨了微生物絮凝机理,对国内外煤炭微生物絮凝技术的研究进展进行了评述。重点针对煤泥水絮凝,具体分析了单一菌种微生物絮凝剂、复合型生物絮凝剂、微生物絮凝剂与非生物絮凝剂复配等对煤泥水的絮凝效果,并根据目前研究中存在的问题指出今后需要研究的方向。
Following an introduction to the start-of-the-art of the research work made worldwide on microbial flocculants and the bacteria produced therefrom,an analysis is made of the chemical constitutions and properties of microbial flocculants,as well as the mechanism of microbial flocculation.Then the paper presents an overview of the progress made both at home and abroad in the treatment of coal slurry water with this technology,with the focal points targeted at coal slurry water flocculation,as well as the efficiency of monobacteria flocculant,compound microbial flocculants,and the effect of combined use of biaflocculant and non-bioflocculant.Finally,the direction of the work that needs to be made in the future is pointed out based on analysis of the problems existing in current research work.
