摘要: 通过利用颗粒状TiO2催化剂（平均粒径0.258 μm）对酸性红B模拟废水的催化降解实验，对一体式光催化氧化膜分离三相流化床反应器的膜污染特性进行了研究。结果表明，TiO2是造成膜污染的主要污染物，且TiO2浓度愈大，膜污染愈严重；本实验体系TiO2的适宜浓度为2 g/L。反应区曝气量在3.6 m3/h时膜污染最小；膜组件底部曝气装置可大大减轻膜污染，且其曝气量以0.6 m3/h为宜。表面冲洗、气体反冲洗和碱洗均可有效地清除膜表面和膜孔内的污染物，使膜通量恢复至90％以上；“表面冲洗＋碱洗”和“表面冲洗＋碱洗＋气体反冲”可进一步提高膜通量的恢复，但不十分明显。

Abstract: The property and control of membrane fouling of integrative reactor, coupling with photocatalysis oxidation and organic membrane separation, were investigated by photocatalytic degrading Acid Red B wastewater with TiO2 which the average granularity diameter is 0.258 μm. The results show that TiO2 is the main influencing factor on membrane fouling, and the fouling become more serious with the increase of TiO2 concentration. The TiO2 concentration should be 2 g/L. The membrane fouling is the lowest when the reaction area aeration volume is 3.6 m3/h. Aeration device under membrane module can decrease membrane fouling greatly, and the aeration flux is as fit as 0.6 m3/h. Facewash, air-backwash and alkaline rising can effectively cleared out the pollutants on the membrane surface and in pores, to make the membrane flux recovery as high as 90％. Although the integrative washing ways that are the alkaline rising followed by facewash and the airbackwash followed alkaline rising after facewash can improve the recover of membrane flux, but the effect is not obvious.
