摘要
正渗透技术是一种新兴的利用渗透原理的膜分离技术,能自发进行,无需外加压力即可实现,为水资源和环境问题提供了低能耗、高效率的解决途径.近年来正渗透技术在国际上得到了广泛的重视,相关的研究正快速发展.文章详细总结了正渗透机理方面的研究进展,深入分析了正渗透的整个动力学过程,为正渗透膜的设计和制备与驱动溶质的选择和开发提供了理论基础.
As a type of novel technology by using the principle of osmosis, forward osmosis is a spontaneous process without exerted pressure. This approach consumes low energy and is highly efficient for contemporary worldwide water and environment problems. Forward osmosis has recently drawn worldwide attention, and relevant studies are in burgeoning development. This review summarizes the progress of study on the mechanism of forward osmosis in detail, analyzes the whole dynamic process in depth and provides a theoretical basis for design and preparation of FO membranes and selection and development of draw solutes.
