煤泥水生物絮凝中助凝剂的研究现状及展望

State-of-the-art and perspective of the research work on coagulant for use in coal slime water biological flocculation

助凝剂作为一类可以提高或改善凝聚和絮凝效果的辅助药剂已被广泛应用于水处理工艺中。文章在对助凝剂类型及主要作用概述的基础上,分析了煤泥水生物絮凝的特点,重点分析阐述了助凝剂在微生物絮凝煤泥水中的研究现状,并根据研究中存在的问题,对煤炭生物絮凝助凝剂的研究发展前景进行了展望。

Coagulant is widely used in water treatment processes as an auxiliary agent for enhancing or improving agglomeration and flocculation effect.Following a brief introduction to the types and main functions of coagulant aids,an analysis is made of the distinctive features of biological flocculation of coal slime water,with the points centered on the state-of-the-art of the research work on the use of coagulant aids in bioflocculation of coal slime water.
