摘要
在压力驱动膜分离过程中,膜污染是影响膜分离性能和使用寿命的关键因素之一.解析污染物在膜表面的形成机理,对高性能抗污染膜研制和提高系统运行稳定性具有重要意义.本文综述了国内外关于压力驱动膜表面污染形成机制、机理模型和计算流体力学模拟的研究进展;重点介绍了颗粒污染的形成机理和影响因素,梳理了用于解释颗粒污染形成的数学模型;总结了计算流体力学在颗粒污染模拟中的应用,为面向压力驱动膜污染的理论计算和仿真模拟提供参考.
In pressure-driven membrane separation processes,membrane fouling is one of the key factors affecting the performance and lifetime of the membrane.Analyzing the formation mechanism of pollutants on the membrane surface is of great significance for the development of high-performance anti-fouling membranes and for improving the stability of system operation.This article reviews the research progress in the formation mechanism of surface fouling of pressure-driven membranes,mechanistic models,and computational fluid dynamics simulations at home and abroad.It focuses on introducing the formation mechanism and influencing factors of particulate fouling and reviews the mathematical models used to explain the formation of particulate fouling.Finally,it summarizes the application of computational fluid dynamics in the simulation of particulate fouling,which provides a reference for theoretical calculation,and simulation modeling of pressure-driven membrane fouling.
