摘要

提出了面向过程的陶瓷膜设计基本研究框架，分析了膜的孔径分布与悬浮液颗粒体系粒径分布对过滤过程的影响，提出采用堵塞因子来表征膜的初始堵塞污染情况，建立了颗粒体系微滤过程中的膜微观结构与性能关系新模型，不仅可以计算膜通量随时间的变化，且能预测陶瓷膜结构参数对膜通量的影响.模拟结果与实验值有较好的一致性.

Abstract

A research framework of application-oriented ceramic membrane design was proposed. The effects of membrane pore size distribution and particle size distribution of suspension on filtration were analyzed. In this work a blocking factor(k) was given to describe membrane fouling and a new crossflow microfiltration model of particle suspensions was built. This model discovers the correlation between membrane permeability and microscopic material structure

by which the variation of permeate flux with filtration time would be obtained and the influences of membrane structure parameters on permeate flux could be predicted.The model calculation showed good agreement with the experimental results.
