摘要
本文就中空纤维膜分离技术的迅速发展和广泛应用,对纤维膜的分离机理,应用技术特征,膜素材及国内外中空纤维膜分离技术的发展现状进行了探讨。认为中空纤维膜是气膜分离中较为理想的膜素材,进一步解决纤维膜自身存在的透气系数与选择性系数之间的矛盾,研究新型纤维膜和纤维膜的改性,是当前继续开发气膜分离的重要研究课题。
In this paper. the rapid development. wide application basic principle, technical feature, Separation material and present condition at home and abroad of hollow filament membrane Separation technique are described. It is agreed that the hollow filament membrane is better material for membrane Separation technique. In order to solve the contradiction between the permeation co-efficient and selection co-efficient of hollow filament membrance itself, developing new filament membrance and improvig its properties are import artreserck subjects for the further application of hollow filament membrane technique.
