摘　　要：在愈来愈严格的发展"绿色工业"要求的环境下,煤化工工业废水"零排放"逐渐成为发展趋势,而高盐废水处理成为实现这一目标的关键突破点。与生化处理、交换树脂分离技术以及超滤、反渗透等膜技术相比,利用蒸发技术处理煤化工高浓盐废水技术成熟,应用广泛,而且更适用于从盐度较高的有机废水中制取大量回用水。分析并比较了自然蒸发、多效蒸发、机械压缩蒸发、多效闪蒸及膜蒸馏法用于高浓盐废水浓缩的优劣和应用现状,针对煤化工高浓盐废水处理所出现的问题提出相关改进建议和思路。As the Zero Discharge for the coal chemical industrial wastewater has become the trend of the stricter demands of Green Industry gradually, high-salinity wastewater treatment is considered as the highlight.In comparison to technologies of biochemical treatment,ion exchange resin separation, and membrane separation including uhrafiltration and reverse osmosis, the evaporation process which is mature and widely applied is more suitable to extract large amount of recycle water from hypersaline organic wastewater.Moreover, the advantages and disadvantages as well as the applications of natural evaporation method, multi-effect distillation, mechanical vapor recompression, multiple-effect flash, and membrane distillation were analyzed and compared.Ultimately ,some suggestions and ideas aiming at solving certain problems in the high-salinity effluent treatment of coal chemical industry were put forward.
