摘　　要：采用相转化法制备PVDF/TPU共混中空纤维膜,选择PVP为添加剂可以改善PVDF/TPU的成膜性能。运行结果表明染料废水中不可降解物质的COD占总COD的4%左右,MBR组合工艺是处理活性染料废水的高效工艺。PVDF membranes blended with thermoplastic polyurethane （TPU）, using poly （vinylpyrrolidone） （PVP） as polymeric hydrophilic were prepared by phase inversion process. The PVDF/TPU hollow fiber membranes were used in MBR process for the treatment of synthetic Reactive Brilliant Blue KN-R dyestuff wastewater. Based on the running result and treatment effect, the result showed COD of non-degradable pollutants account only around 4% of the total COD.
