微生物絮凝剂的研究现状与发展趋势

Present Status Quo and Trend of Studies on Microbial Flocculants

相对于传统絮凝剂而言,微生物絮凝剂具有絮凝效果好、应用范围广、易生物降解、对环境安全、无二次污染的特点。文章综述了微生物絮凝剂的类型和特点,详细阐述了其絮凝机理,分析了影响微生物絮凝剂絮凝性能的因素以及微生物絮凝剂在水处理中的应用。指出了当前微生物絮凝剂研究存在的问题以及今后的发展趋势。

Compared with the traditional flocculants, microbial flocculant has advantages of high removal efficiency, wide applicability, good biodegradability, safety for environment and no secondary pollution. In this paper, the classification, features and flocculating mechanism of microbial floeculants were introduced. The factors affecting flecculation and the application of microbial flocculants for water treatment were analyzed. The existing problems in the studies were pointed out as well. Moreover, the developing trends were previewed.
