摘要：The brine from vinylidene chloride (VDC) synthesis contains high concentration of sodium chloride and halogenated hydrocarbons which are all volatile organic chemicals (VOCs). Based on the contaminations' characteristics in the brine, an air-stripping process was firstly applied for removing most of the halogenated hydrocarbons in the brine, and then the H2O2/UV oxidation process was used for polishing treatment so that the treated brine could be reused as a raw material for a chloro-alkali process. The results showed the residual TOC after air-stripping could be effectively removed by H2O2/UV process, and the TOC level of the brine from VDC production could be decreased to less than 10mg/L through combined air-stripping and H2O2/UV oxidation process, and than the treated brine could be reused as raw material for a chloro-alkali process. ?
