超滤膜系统内部结构对膜过滤性能的影响
Influence of Internal Structure of UF System on Filtration Performance of Membrane
摘要
Abstract
Influence of property of immersed ultrafiltration (UF) membrane by transforming its internal structure was investigated. Result shows, filtration property can be improved by increasing membrane ratio of length/height (L/H). Best treatment efficiency can be got when L/H ratio value reaches 1.07. Increasing L/H radio can also improve the efficiency of aeration but has little effect on improving the backwashing . Effectiveness of membrane filtration, aeration and backwashing of bilateral outlet method are all better than those of unilateral outlet method . Bilateral outlet method shall be selected priority . Backwashing way, which use air and water both after using water only, has a good effect on membrane filtration.关键词
