  • 摘要: 二甲基亚砜（DMSO）废水因其COD高、可生化性差的特性而较难处理。本实验以采用硫酸二甲酯法生产DMSO的某化工厂废水为研究对象，设计并建立了组合式光催化氧化装置联合水解酸化+MBR工艺的中试系统，探讨了组合式光催化氧化装置、氧化剂投加量、pH、反应时间和水力停留时间对系统处理效果的影响。结果表明，组合式光催化氧化装置可有效提高DMSO废水的可生化性。最优工艺参数为：按H2O2与原水COD质量浓度比为2：1投加H2O2，在pH值为4、反应时间为6 h、水力停留时间为4 h的条件下，该系统对原水COD（5 000 mg/L）去除率大于98%，出水COD达到《污水综合排放标准》（GB 8978-1996）一级要求。
    Abstract: The dimethyl sulfoxide(DMSO) wastewater is difficult to be treated because of the high chemical oxygen demand(COD) and the poor biochemical degradability. In this study, we used the wastewater from a plant that produced DMSO by the dimethyl sulfate as raw water. A pilot system of UV/H2O2/TiO2 combined with hydrolytic acidification-membrane bioreactor (MBR) process was designed and established. Then, the influences of UV/H2O2/TiO2, total dosage of oxidizers, pH, reaction time and hydraulic retention time on treatment effect were discussed. The result showed that the biodegradability of DMSO could be greatly improved by UV/H2O2/TiO2. The optimum process parameters were that the mass concentration ratio of H2O2 and COD was 2:1, the pH was 4, the reaction time of hydrolytic acidification was 6 hours and the hydraulic retention time of MBR was 4 hours. Under the above conditions, the removal efficiency for COD (5 000 mg/L) was above 98% and the effluent COD could meet the first criteria specified in Integrated Wastewater Discharge Standard (GB 8978-1996).
