PVDF/TPU共混中空纤维膜的表征及MBR处理染料废水性能的影响研究
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. Abstract: 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. 作 者: 周媛 刘浩 奚旦立 ZHOU Yuan LIU Hao XI Dan-li 作者单位: 东华大学环境科学与工程学院,上海,201620 期 刊: 中山大学学报(自然科学版) ISTICPKU Journal: ACTA SCIENTIARUM NATURALIUM UNIVERSITATIS SUNYATSENI 年,卷(期): 2007, 46(z1) 分类号: X703.1 关键词: 聚偏氟乙烯中空纤维膜 热塑性聚氨酯 聚乙烯吡咯烷酮 膜生物反应器 染料废水 Keywords: polyvinylidene fluoride hollow fiber membrane thermoplastic polyurethane polyvinyl pyrrolidone membrane bioreactor dyestuff wastewater【PVDF/TPU共混中空纤维膜的表征及MBR处理染料废水性能的影响研究】相关文章:
