摘要
随着全球淡水资源紧缺区域增多,在过去的数十年里淡化海水因其来源广且不受降雨影响,而成为解决淡水短缺的可行方案,并得到越来越多关注和发展。海水淡化工艺(即脱盐)将海水分为两部分:淡水和高浓度的盐水。虽然海水淡化的工艺装备和支撑技术已经相当成熟,但为了不断提高技术并降低成本,国内外进行了大量的研究。该文概述了海水淡化主流技术的研究现状、工程项目以及新工艺。另外归纳了海水淡化工艺装备存在的一般问题,结合"十二五"规划,指出了海水淡化的研究方向。
Because of free from the variations in rainfall and wide sources, seawater desalination is a feasible water resource for the shortage of fresh water. A number of desalination technologies have been considered and developed significantly during the last several decades to augment the supply of water all around the world. A seawater desalination process separates seawater into two streams： a fresh water stream and a concentrated brine stream. Although the process equipment and support technologies are mature enough to be a reliable source for fresh water from the sea, a significant amount of research and development （R＆D） has been carried out in order to constantly improve the technologies and reduce the cost of desalination. Current status, practices, and advances that have been made in the realm of seawater desalination technologies were reviewed in this paper. Additionally, an overview of R＆D ac- tivities and outlines future prospects for the state-of-the-art seawater desalination technologies in combination with five-year plan and general problems for process equipment was put forward.
