Abstract： Highlysaline wastewater in the chemical industry has the characteristics of complex composition，strong toxicity，dificultdegradation，etc.Directdischarge willcauseserious environmental polutionand ecologicaldamage. Thetraditionaltreatmenttechnology hassome problems，suchaslow eficiency，highcostand secondarypollution.Based onthis，bysystematicallyanalyzingzero emisiontechnologiessuchasmembraneseparation，evaporativecrystallization， electrodialysis，andion exchange，aprocess flowof "pretreatmentconcentrationseparationcrystalizationsolidification" is constructed.Throughtechnology integrationand processoptimization，zeroemissionresourceutilizationofhigh salt wastewaterisachieved，providing theoreticalsupportfor the sustainable developmentof the chemical industry.
