摘　　要：分析评述目前正向渗透技术的研究和应用进展,指明其发展方向.正向渗透技术在物料浓缩、物质分离过程中体现了独特的低能耗特点,能完成低能耗的海水淡化、果汁浓缩等物料分离过程,同时可用于海水发电.研发和制备高通量、抗污染、高强度的正向渗透膜材料是正向渗透技术在各领域应用的基础.目前的汲取液已经从常规的无机盐系列、有机溶液等向复配溶液和易回收溶质的研究上转变,纳米材料也开始进入研究人员的视线.Progress and trend in forward osmosis （FO） technology research and application was discussed in this paper. FO technology can process material concentration and separation with uniquely low energy consumption, is applicable in the low-energy-consuming separation of seawater desalination and fruit juice concentration, and in generating ocean salinity energy. Development and preparation of forward osmosis membrane materials with high flux, high strength, and anti pollution characteristics forms the basis for FO technology application in various fields. The choice of draw solution has been changed from conventional inorganic salt or organic solution to the mixed solution and easy recovery solute, and Nanomaterials are attracting increasing attention of the researchers.
