Comparative study on four membrane modules in membrane filtration process of Huanglian Jiedu decoction

目的:以中药复方黄连解毒汤为实验对象,比较FMX旋转圆盘平板、中空纤维、管式、过滤杯4种膜组件的膜过滤过程。方法:在相同实验操作条件下,从膜过滤通量、膜阻力分布、指标性成分透过性、膜污染等多个方面,比较4种膜组件对黄连解毒汤的膜过滤情况。结果与结论:FMX、中空纤维、管式膜组件3种动态过滤形式的膜组件比静态死端过滤形式的过滤杯膜组件,在膜通量、膜污染度、指标成分透过性方面具有较为明显的优势;而使流体呈现强烈涡旋状态的FMX膜组件在膜通量、膜污染方面又比管式、中空纤维膜组件具有优势。

Objective： To compare the membrane filtration process of four membrane modules namely, FMX rotating disk flat membrane module, hollow fiber membrane module, tubular membrane module and filter cup membrane module, with traditional Chi- nese medicine compound Huanglian Jiedu decoction as the experimental subject. Method： Under the same experimental operating conditions, the four membrane modules in membrane filtration process of Huanglian Jiedu decoction were compared in terms of permeate flux, resistance distribution, transmittance of index components and membrane fouling. Result and Conclusion： Three membrane modules in the dynamic filtration form FMX rotating disk fiat membrane module, hollow fiber membrane module and tubular mem- brane module had more advantages than filter cup membrane module in the static dead-end filtration form in terms of permeate flux, transmittance of index components and membrane fouling. However, FMX membrane module that made the fluid in a strong vortex status had better performance than hollow fiber membrane and tubular membrane module in permeate flux and membrane fouling.
