对管式陶瓷膜十字流微滤过程中的流体流动方式和原位再生膜的方式与周期进行了优化研究．结果表明，外旋流方式和压气反吹的原位再生方法相结合能够使管式陶瓷膜十字流微滤过程得到较大程度的强化，即微滤过程中的浓差极化和膜污染得到有效控制；在较高频率的压气反吹情况下，该微滤过程的过滤通量能在较长时间内保持不下降．研究结果为管式陶瓷膜十字流微滤的高效膜器结构与工艺设计提供了依据． The flow pattern and the mode and period of in-situ regenerated membrane during microfluidic process of cross-flow microfiltration were investigated. The results show that the combination of external swirling method and in-situ regeneration by pressurized backflushing can enhance the cross-flow microfiltration process of the tubular ceramic membrane to a great extent, that is, the concentration polarization and membrane fouling in the microfiltration process are obtained Effective control; in the case of higher frequency of pressure blowback, the filtration flux of the microfiltration process can not decline over a long period of time. The research results provide the basis for the design of efficient membrane structure and process of the cross-flow microfiltration of tubular ceramic membranes.
