摘　　要：对传统三氯异氰尿酸废水处理工艺进行改进,利用真空脱氯提高脱氯效率,H2O2还原游离氯而不引入杂原子,利用脱氯产生的氯气进行氯气氧化,并联合膜过滤处理将废水中氰尿酸质量浓度降低至5mg·L^(-1)以下,总铵量低于2 mg·L^(-1),满足电解装置进水要求,实现废水资源化。The traditional trichloroisocyanuric acid wastewater treatment process was improved by increasing dechlorination efficiency under vacuum conditions,using hydrogen peroxide to reduce free chlorine without introducing other atoms.Through the combined treatment of chlorine oxidation and membrane filtration,the cyanuric acid mass concentration in the wastewater was reduced to less than 5 mg·L^(-1),and the total ammonium mass concentration was less than 2 mg·L^(-1),which met the water intake requirements of the electrolysis device and realized the recycling of wastewater.
