摘要
介绍了近几年来国内外微生物絮凝剂的发展概况、分类及絮凝机理,指出了与传统絮凝剂相比较微生物絮凝剂在水处理中的优越性,分析了已使用的微生物絮凝剂在污水达标治理过程中存在的问题,并探讨了开发廉价、高效、可降解微生物絮凝剂的发展趋势和研究方向。
The paper reviews the development, characteristics and classification of microbial flocclants. The mechanism of flocculation and influencing factors were analyzed, and the limits of traditional flocculants and the superiorities of the microbial floceulants in water trealment were discussed. Combined with the complicated practice of wastewater, the problems of microbial flocculant in application were lised. Moreover, the research trend of cheap, high efficient and biodegradable flocculants was probed.
