Research on Salt Refining and Purification of High-salt Wastewater Incineration
The source of high-salt wastewater is wide,and incineration has the advantages of short process flow and small equipment for treating high-salt wastewater.At the same time,it can completely incinerate the pollutants in the oxidized wastewater.However,this process produces a large amount of waste salt,which contains a large amount of toxic and harmful substances with complex components and strong toxicity,which are difficult to degrade.In this paper,a combination process of dissolution,filtration,and re-evaporation crystallization is used to refine and purify the salt from the high-salt wastewater incineration,which can increase the purity of sodium sulfate to over 95%,the moisture content to less than 6%,the TOC to less than 30 mg/L,and the purity of sodium chloride to over 93%,the moisture content to less than 6%,the TOC to less than 30 mg/L,reaching the second-level standard of solar salt.
