焦化废水生化处理研究进展

Study progress of biochemical treatment of the coking-plant wastewater

焦化废水是一种典型的含难降解有机污染物的工业废水,除含酚类物质以外,还含有多种芳香烃和杂环类有机物,成分十分复杂,且该废水水量大,对环境污染严重。因此,焦化废水的处理研究一直是国内外环境工作者关注的焦点之一。概述了近年来焦化废水成分检测方法,系统介绍了焦化废水生化处理技术的最新研究进展,阐述了影响NH3-N、F-、COD、有机污染物及色度去除的主要因素。

The coking-plant wastewater is a kind of industrial wastewater, wh ich has excessive non-degradation organics pollutants. Besides phenol, aromatic alkyls and heterocyclic organic pollutants are difficult to treat. Its quantity is very large. So the treatment of the coking-plant wastewater is always the foc us of environmental staffs in the world. It summarizes the determination of the content of the coking-plant wastewater for recent years, recommends the latest s tudy of the biochmical treatments, expounds the predominant factors which affect the removal of NH3-N, F-, COD, the organic pollutants and chroma.
