絮凝沉淀法处理煤化工废水的研究进展

Research Progress of Flocculation and Precipitation Method for Treating Coal Chemical Wastewater

絮凝沉淀法在水处理中的应用非常广泛,在煤化工废水处理中也占有一席之地。此法既可以降低废水的浊度、色度,又可以除掉有毒有害的各类有机污染物和悬浮物。通过查阅总结近年来关于絮凝沉淀法处理煤化工废水的研究的文献以及其他相关资料,对目前絮凝沉淀法所用各类絮凝剂的研究情况进行了总结。并对处理煤化工废水絮凝剂的发展前景进行了展望。

Flocculation and sedimentation method is widely used in water treatment and has a place in the treatment of coal chemical wastewater.This method can reduce the turbidity and chromaticity of wastewater,and also get rid of toxic and harmful kinds of organic pollutants and suspended matter.This paper summarizes the research on flocculation and precipitation method for treating coal chemical wastewater by reviewing the literature and other related information in recent years,and summarizes the current research on various flocculants used in flocculation and precipitation method.The development prospect of flocculants for coal chemical wastewater treatment is also presented.
