焦化废水深度处理现状及技术进展

Research on the Status and Technical Progress of Advanced Treatment of Coking Wastewater

焦化废水是在炼焦、煤气高温干馏等生产过程中产生的高浓度、难降解的有机废水。其成分极其复杂,污染物浓度高,而且色度高,水质变化波动大,毒性强。当前,焦化废水处理技术主要有好氧生物处理技术、活性炭吸附技术及芬顿氧化处理技术等,但均存在一些问题,不能满足日益增长的环保需求。本文综述了焦化废水处理技术现状,展望了其未来发展方向。

Coking wastewater is a high-concentration,difficult-to-degrade organic wastewater produced during production processes such as coking and high-temperature coal gas distillation.Its composition is extremely complex,the concentration of pollutants is high,and the color is high,the water quality fluctuates greatly,and the toxicity is strong.Currently,coking wastewater treatment technologies mainly include aerobic biological treatment technology,activated carbon adsorption technology and Fenton oxidation treatment technology,but they all have some problems and cannot meet the increasing environmental protection needs.This paper reviews the status quo of coking wastewater treatment technology and looks forward to its future development direction.
