Abstract：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 components and high chroma. COD， NH3-N， total nitrogen and the contents of cyanide can not meet the standard after pretreated and biochemical treatment. Advanced oxidation process， coagulation sedimentation method， adsorption method， membrane separation method， biological chemical method and their combined process can make the effluent meet the requirements of the new standard. In addition， the present status of advanced treatment processes of coking wastewater in China are described and prospected.
