摘要
近年来,水资源危机日益加重。在海水淡化技术中,与反渗透分离技术相比,正渗透分离技术作为一种低能耗、绿色的解决方案,具有明显优势,在国际上得到了广泛的重视,是膜分离技术的研究热点之一。本文从正渗透膜材料结构与性能关系的角度,对膜材料的最新进展进行了综述,同时分析了汲取液的常见类型,并简述了正渗透分离技术的新应用,展望了其未来的发展前景。
In recent years, water resources crisis is aggravated. As a low energy consuming and a green energy technology, the forward osmosis (FO) separation technology has obvious advantages compared to the reverse osmosis (RO) separation technology in seawater desalination. FO has attracted worldwide attention and is one of the hot of study of membrane separation technologies. In this review, the state-of-the-art in FO membrane materials was summarized from the perspective of the relationship between structure and properties of them, and the common types of draw solution were analyzed. The latest applications and development prospects of FO were also introduced.
