摘要
焦化废水含有大量有机污染物和有毒无机物,成分复杂,污染物色度高,属较难生化降解的高浓度有机工业废水。经常规方法预处理,再经生化处理后的焦化废水存在氰化物、COD及氨氮等不达标的问题。通过臭氧氧化法、Feton试剂氧化法以及光催化氧化法等高级氧化法,活性炭以及矿物吸附法等三级深度处理可以解决这一问题。介绍了目前焦化废水深度处理的研究进展并进行了展望。
The coking-plant wastewater contains lots of organic contaminants and toxic inorganic contaminants. This kind of highly concentrated organic industrial wastewater is hard to be biodegraded due to its complex component and high chroma. The contents of cyanide, COD and NH4^＋-N exceed the standard in the coking-plant wastewater, after pretreated by regular method and biochemical treatment. This problem can be solved by the advanced oxidation processes, active carbon and mineral adsorption method, etc. The progress in the research on advanced treatment of coking-plant wastewaster by adsorption method is introduced and looked ahead.
