摘要:
综述了在油水分离中减缓膜污染、提高过滤效率的途径,即可以通过优化膜的孔径、膜表面亲水改性、构筑三维网孔结构的新型分离膜以及使用膜清洗等方法提高膜的抗污染性能。研究表明:控制膜孔径略小于油滴直径时能获得较理想的分离效率与较大的渗透通量;SiC陶瓷膜及表面负载Al2O3、TiO2、ZrO2等物质的其他分离膜具有亲水疏油性并且能够提高膜的抗污染性能,可使油滴截留率提高到98%以上,减缓膜污染;利用化学气相沉积技术构筑的CNTs三维网孔状结构膜可使油截留率达到100%;最后,采用化学清洗结合反冲洗可有效恢复陶瓷膜的膜通量。
Abstract:
The methods of alleviating the membrane fouling and improving filtration efficiency in oil/water separation were summarized,such as the improving anti-fouling performance of membrane by optimization of the pore diameter of membrane,the hydrophilic modification of membrane surface,the construction of a novel separation membrane with three-membrane network structure,the membrane cleaning,etc. Studies have indicated that the more ideal separation efficiency and the larger permeation flux can be obtained when the pore diameter of membrane is controlled to be slightly smaller than the diameter of oil droplet. SiC ceramic membrane and other separation membranes with Al2O3,TiO2,ZrO2,etc. on the surface possess the hydrophilic and oleophobic properties and can improve the anti-fouling property of membrane,which can increase the oil rejection rate to more than 98% and alleviate membrane fouling. The oil rejection rate can reach 100% by using CNTs membrane with three-membrane network constructed by chemical vapour deposition technique. Finally,the membrane flux of ceramic membrane can be effectively restored with chemical cleaning combined with backwashing.
