摘　　要：本文针对聚砜制膜废水特点 ,采用溶剂萃取 -常、减压蒸馏 -活性炭吸附的集成工艺 ,进行了该废水治理的工艺研究。结果表明 ,该工艺可使废水中的 COD值由原来的 2 0 0 0 0～ 3 0 0 0 0 mg/L降低到 40～ 6 0 mg/L ,达到国家排放标准。According to the characteristics of wastewater from preparation of polysulfone membrane, an integrated technique of solvent extraction, normal and vacuum distillation and active carbon adsorption was applied to the investigation of wastewater treatment. The results indicated that the COD value of the wastewater was decreased from 20000-30000mg/L to 40-60mg/L, which satisfied the national drainage standard.
