In the present paper, the reasons of concentration polarization were analyzed and methods for reducing concentration polarization were suggested.
分析了膜分離中的濃差極化現(xiàn)象的產(chǎn)生原因，并提出與此對應的減弱措施。
Firstly, the development of the concentration polarization model or the force balance model is reviewed based on the back-diffusion and lateral migration of particles changing with process parameters.
首先是基于溶質(zhì)微粒反向擴散或溶質(zhì)微粒的橫向遷移現(xiàn)象分別闡述了濃差極化類模型和力平衡類模型的發(fā)展演變過程；

濃差極化
We find:Surface deposited resistance,blockage resistance and degree of membrane fouling are positively correlated,while have a negative correlation between membrane itself resistance,concentration polarization resistance and degree of membrane fouling. Membrane flux is inversely related to degree of membrane fouling.
