Abstract: This paper introduces the difficulty in treating with high-salinity wastewater from the coal chemical industry and analyzes the present situation of high salt wastewater treatment technologies.The characteristics,treatment effects and application progress of various patented technologies are reviewed.This paper also discusses the new comprehensive utilization ways for high-salinity wastewater and concerning crystallized salt,including that high-salinity wastewater is used as make-up water in coal washery,high-salinity wastewater and concerning crystallized salt are burned together to solidify,and the crystallized salt is used as raw materials for production of soda.As for the high-salinity wastewater treatment,it is proposed to accelerate the development and industrial application of the high-salinity wastewater fractional crystallization technology and strengthen research and formulation of product standards for the crystallized salt,a byproduct from the treatment of high-salinity wastewater in the coal chemical industry.
