摘　　要：采用高级氧化／生物法组合工艺处理含二甲基甲酰胺（DMF）、二甲基乙酰胺（DMAC）等强有机溶剂的制膜废水。结果表明，曝气微电解和催化电氧化技术去除强有机溶剂的最佳pH值分别为（2～3）、（5～6），最佳水力停留时间分别为120、（90～120）min；高级氧化技术可大大提高废水的可生化性，将B／C值从0．30提高到0．55左右；高级氧化／生物法组合工艺不仅具有很强的抗冲击负荷能力，且处理效果很好，出水水质达到《污水综合排放标准》（GB8978—1996）的一级排放标准。The combined process of advanced oxidation and biological treatment was used to treat membrane-making wastewater containing strong organic solvents, such as dimethylformamide （DMF） and dimethylacetamide （DMAC）. The results show that the optimal pH value for removing strong organic solvents by aerated micro-electrolysis and catalytic electro-oxidation technology are 2 to 3 and 5 to 6 respectively, and the optimal hydraulic retention times （HRT） are 120 min and 90 to 120 min respectively. The advanced oxidation technology can greatly improve the wastewater biodegradability, and increase the B/C value from 0.30 to 0.55. The combined process of advanced oxidation and biological treatment has strong resistance to shock loading and excellent treatment effect. The effluent reaches the first class criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 -1996）.
