摘要: 对现有的微滤通量模型进行了阐述.首先是基于溶质微粒反向扩散或溶质微粒的横向迁移现象分别阐述了浓差极化类模型和力平衡类模型的发展演变过程;其次是基于溶质(或微粒)在孔内的收缩堵塞及在膜表面上的吸附或沉积特性,对堵塞过滤定律和Darcy 定律及其发展过程分别进行了阐述.再次,基于膜表面上多种效应的协同作用叙述了集成模型的进展情况.最后展望了未来微滤膜通量模型可能的研究发展方向.

Abstract: The existing micro-filtration flux models are described in three sections.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.Secondly, the blocking mechanisms, the Darcy’s law and their development are introduced based on the adsorption of particles in membrane pore or the characteristics of deposition of particles on membrane surface.Thirdly, the combined model which takes into account the interaction of different factors is reviewed.Meantime, the potential future directions of predicting micro-filtration membrane flux model are discussed.
