Discussion on coking wastewater treatment and control measures in iron and steel enterprises

Abstract

According to the water quality characteristics of coking wastewater and the environmental protection requirements, the status of coking wastewater treatment technologies at home and abroad was described. Several methods and control measures of coking wastewater treatment were discussed in the effluent from iron and steel enterprises. It is an effective way to makes use of cleaner production technologies to reduce the amount of coking phenol cyanide wastewater produced from the source, and then adopt water supply for different water quality or series classification in-house according to the demand of water characters. It is necessary though looking for the available disposal way to reduce the coking wastewater effluent, which can provide a reference for process selection and research on treatment of coking wastewater in iron and steel enterprise.
