摘要: 对生物反应器———膜过滤复合过程处理模拟腈纶废水进行了研究,探索了膜微滤过程中的污染机
理。通过对微滤膜处理模拟腈纶废水过程中各部分阻力进行分析,结果表明在较低操作压力条件下,膜的污染主要
是浓差极化和滤饼层污染;在较高操作压力条件下,则主要是来自滤饼层污染;来自膜孔阻力和膜自身的阻力较小
是膜污染的次要因素。提出了膜清洗的具体方案,用质量分数1%的双氧水溶液清洗30min或0.1mol/L的氢氧化
钠溶液清洗60min,均可以使膜通量恢复到较好的水平。

Abstract:  

It was studied simulated acrylic fiber wastewater treatment used membrane bioreactor. In Lab research, the fouling mechanisms of the membrane in microfihration were studied. Every kind of resistances in the simulated acrylic fiber wastewater treatment was analyzed. The results show that the fouling is mainly from concentration polarization and cake layer under the conditions of the lower operating pressure. However, the fouling mainly from cake layer under the conditions of the higher operating pressure. The resistances from the block and itself is small, thus, they are the minor factors for the membrane fouling. The method of membrane cleaning were proposed, that is, membrane flux is up to better level after 1% H2O2 solution washing for 30 min or 0.1 mol/ L NaOH solution washing for 60 min.
