| 摘 要： | 廉价的无纺布为基膜,采用抗坏血酸还原法制备了Ag/TiO2-PVA复合膜,研究Ag/TiO2-PVA复合膜膜生物反应器的膜组件的抗污染性能和处理性能。结果表明,Ag/TiO2-PVA复合膜能明显降低跨膜压力和膜污染阻力,提高膜通量,特别是对滤饼层表现出很好的抑制作用,显示出较好的抗污染性能,但是也导致出水浊度增加。Ag/TiO2-PVA复合膜还显示出一定的光催化性能,其出水CODcr值低于对照组。

| Abstract: | In this research paper, low cost non-woven fabric was used as base membrane and Ag/TiO2-PVA composite membrane was prepared using ascorbic acid reduction method. Anti fouling and wastewater treatment performances of membrane module of Ag/TiO2-PVA composite membrane bioreactor were studies. The results showed that Ag/TiO2-PVA composite membrane could obviously reduce the transmembrane pressure and membrane fouling resistance, and improve membrane flux. Especially, there were very good inhibition to filter cake layer and good anti fouling performance. But effluent turbidity was increased. Ag/TiO2-PVA composite membrane had also some photocatalytic property. The CODcr values of effluent were lower than those of the control group. |
