摘　　要：利用聚乙烯三管微滤膜在不同浓度、不同操作压力下,分别以切向进料和径向错流进料进行了分离实验对比研究,结果表明:在浓度为0.25%时三管膜切向进料具有通量大、能耗低的特征;切向进料的渗透通量是径向错流进料的2倍,且在浓度为0.5%时切向进料有一最佳操作压力,为深入研究多管膜过滤提供了依据。Separation process was investigated with 3-tube polyethylene microfiltration membrane based on the difference in concentration,operation pressure and inlet arrangement. Results indicated that the 3-tube membrane showed characteristics of higher permeation flux and less energy consumption when the concentration was 0.25%. The permeation flux with tangential inlet was 2 times of that with radial inlet. An optimum operation pressure was observed for the rotating flow of tangential inlet when the concentration was 0.5%.
