PVDF/TPU共混中空纖維膜的表征及MBR處理染料廢水性能的影響研究
摘要: 采用相轉(zhuǎn)化法制備PVDF/TPU共混中空纖維膜,選擇PVP為添加劑可以改善PVDF/TPU的成膜性能.運(yùn)行結(jié)果表明染料廢水中不可降解物質(zhì)的COD占總COD的4%左右,MBR組合工藝是處理活性染料廢水的高效工藝. 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 劉浩 奚旦立 ZHOU Yuan LIU Hao XI Dan-li 作者單位: 東華大學(xué)環(huán)境科學(xué)與工程學(xué)院,上海,201620 期 刊: 中山大學(xué)學(xué)報(bào)(自然科學(xué)版) ISTICPKU Journal: ACTA SCIENTIARUM NATURALIUM UNIVERSITATIS SUNYATSENI 年,卷(期): 2007, 46(z1) 分類號(hào): X703.1 關(guān)鍵詞: 聚偏氟乙烯中空纖維膜 熱塑性聚氨酯 聚乙烯吡咯烷酮 膜生物反應(yīng)器 染料廢水 Keywords: polyvinylidene fluoride hollow fiber membrane thermoplastic polyurethane polyvinyl pyrrolidone membrane bioreactor dyestuff wastewater【PVDF/TPU共混中空纖維膜的表征及MBR處理染料廢水性能的影響研究】相關(guān)文章:
