摘　　要：焦化废水是煤焦化过程产生的废水,含有高浓度的酚类、苯系物、杂环化合物、多环化合物等有机污染物,并且高盐、高氨氮,是一类难处理的工业废水。随着国家对焦化废水的管理日趋严格,传统的"预处理+生化处理"工艺很难满足排放或回用要求,因此对焦化废水的深度处理势在必行。从物化法和生化法两个方面对目前焦化废水深度处理常用技术的研究和应用情况进行了介绍,并探索性地提出了焦化废水深度处理技术未来的研究和发展方向。Coking wastewater is the wastewater produced from coal coking process,and contains highly concentratedorganic pollutants,such as phenols,benzene and its derivatives,heterocyclic compounds and polycycliccompounds,etc. It also contains high salinity and high ammonia nitrogen. These characteristics make cokingwastewater a kind of refractory industrial wastewater. Since the management of coking wastewater becomes strict dayby day,the traditional pretreatment plus biological treatment process cannot meet the requirements for its dischargeor reuse. Therefore,the advanced treatment of coking wastewater is imperative. The research and applicationsituation of the commonly used technologies for the advanced treatment of coking wastewater are introduced in twoaspects：physical-chemical method and biochemical method. The future research and development direction of theadvanced treatment of coking wastewater are proposed tentatively.
