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

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.
