摘　　要：膜洗滤过程包括浓缩环节和顶洗环节,并可简化为单一的浓缩或顶洗,是压力驱动型筛分截留膜分离过程的一种基本工艺模式。膜洗滤过程的模型化研究,涉及从微观渗透传递机理到宏观工艺过程的宽范围内容,存在变量多、形式复杂、求解困难等问题。本文在分析和总结膜洗滤过程的基础上,按照间歇顶洗和连续顶洗的类别,分别综述了膜洗滤过程的物料衡算模型和时间优化模型的相关研究,并对多参数协同优化的膜洗滤过程的模型化研究进行了展望。在应用过程中,系统性理论模型的支持,能够在有限的实验和定性判断基础上确定膜处理工艺和参数,这将为膜设备性能的发挥和生产效率的提高提供关键理论支撑。Diafiltration is a basic mode of membrane filtration processes,and it can be performed as concentration mode or dilution mode.The modeling of diafiltration process involved a wide range of content,from the micro infiltration transfer mechanism to the macro process technology.Furthermore,various parameters and complex form make it difficult to obtain a theory resolution.In this work,the mass balance model and time-optimization model are summarized with batch operation and continuous operation respectively.The comprehensive modeling approach of diafiltration processes with multi-parameters collaborative optimization.Based on the theoretical support,the diafiltration processes can be optimized on the experiments,which will provide key theoretical support for the performance of membrane equipment and the improvement of production efficiency.
