焦化废水高级氧化处理技术研究进展

Research on Advanced Oxidation Processes of Coking Wastewater

焦化废水是煤制焦化产品回收过程中产生的废水,其成分复杂多变,属于难处理的工业废水.介绍了臭氧组合氧化、光催化氧化、电化学氧化、超声波处理、湿式催化氧化及微波诱导催化氧化等高级氧化技术在焦化废水处理中的研究现状,分析了各处理方法的特点和存在的问题,并展望了其应用前景.

The coking wastewater is a kind of industrial wastewater from the coking products of coal,whose components are complicated and various. The research process,such as ozone oxidation,photo-catalytic oxidation,electrochemical oxidation,Sonochemical oxidation,wet catalytic oxidation and microwave-induced oxidation process and so on,are introduced. The features and the existing problems of each treatment are analyzed,suggestions and prospects are proposed.
