污水治理中PVDF改性膜的应用研究

Research on the Application of PVDF Modified Membrane in Wastewater Treatment

利用氢氧化钾(KOH)/甲醇(CH_(3)OH)、KOH/高锰酸钾(KMnO_(4))、KOH/KMnO_(4)/四丁基溴化铵(TBAB)对聚偏氟乙烯(PVDF)膜的疏水性进行化学改性,并将PVDF改性膜应用在污水处理过程中,对其处理能力和抗污染能力进行分析。

Potassium hydroxide(KOH)/methanol(CH_(3)OH),KOH/potassium permanganate(KMnO_(4)),and KOH/KMnO_(4)/tetrabutylammonium bromide(TBAB)were used to chemically modify the hydrophobicity of polyvinylidene fluoride(PVDF)membranes.The PVDF modified membranes were applied in the wastewater treatment process to analyze their processing and anti pollution capabilities.
