摘要: 为了测试不同的中空纤维超滤膜在污水处理方面的性能,本文采用三种不同材料的中空纤维超滤膜:聚醚砜、聚丙烯和聚丙烯腈超滤膜,分别过滤了自来水和污水。讨论了过滤前后,水的色度、浊度、PH值、电导率、氨氮含量、化学需氧量和水流量的变化,并通过扫描电镜观察过滤前后三种超滤膜的表面和横截面微观形态的变化。试验结果表明:在三种超滤膜中,聚醚砜超滤膜在污水处理中表现出了最好的综合应用性能。三种超滤膜对污水中的氨氮和化学需氧量的去除率有限,采用二级或三级过滤可以提高过滤效果。电镜实验还说明,指状结构比孔状结构的防污性能好。

Abstract: Research of Hollow Fiber Ultrafiltration Membrane in water Treatment WEN pei,QIAN Jianhua (College of Materials and Textiles, Zhejiang Sci-Tech University, Hangzhou 310018, China) Abstract In order to test the performance of different hollow fiber ultrafiltration menbranes in waste water treatment., three kinds of hollow fiber ultrafiltration membranes are used in filtering of tap water and waste water. They are PES,PP and PAN ultrafiltration membrane. The change of color, turbidity, PH value, conductivity, ammonia nitrogen content, COD and water flow before and after filtration are evaluated. Scanning electron microscopy (SEM) images of membrane surface and cross-section are used to observe the membrane morphology. The result shows that PES ultrafiltration membranes have the highest comprehensive performance. Ability of Ultrafiltration membranes removing ammonia nitrogen and COD are limited, while this situation can be improved by using two or three membrane filtration systems. The finger-like pore structure shows better antifouling performance than the pore structure. Key words PES ultrafiltration membrane; PP ultrafiltration membrane; PAN ultrafiltration membrane; Waste water treatment; SEM

Key words: PES ultrafiltration membrane, PP ultrafiltration membrane, PAN ultrafiltration membrane, waste water treatment
