摘　　要：文章介绍了目前焦化高盐废水的处理工艺和利用途径,分析了分盐结晶技术在焦化废水处理中的制约因素和解决方案。某焦化企业焦化高盐废水在现有生化处理、深度处理、膜浓缩处理的基础上,对高盐水采用深度氧化、分盐结晶处理方案,进一步去除焦化高盐废水中的有机物、氨氮、氟化物等污染物,实现废水回用,并通过蒸发结晶生产氯化钠、硫酸钠两种高品质结晶盐副产品,实现了焦化废水的资源化、零排放。In the paper,it is introduced current treatment processes and utilization ways of coking high salinity wastewater as well as analyzed the restraining factors and solutions for technologies of salt separation and crystallization in treatment of coking wastewater.The treatment scheme of deep oxidation,salt separation and crystallization for coking high salinity wastewater is adopted by a coke making enterprise based on the existing biochemical treatment,deep treatment and membrane concentration treatment to further remove such pollutants as organic matters,ammonia nitrogen and fluoride in coking high salinity wastewater so that wastewater recycling is realized.Moreover,the recycling and zero discharge of coking wastewater are realized through producing such two high quality by products of crystal salt as sodium chloride and sodium sulfate by evaporation crystallization.
