离子交换法在海水淡化中的应用

The Application of Ion Exchange Method in Seawater Desalination

随着我国经济的快速发展,用水量急剧增加。沿海地区由于经济发达、人口众多,对水资源的需求量更大,水资源严重匮乏,海水淡化将成为解决沿海城市淡水资源短缺的重要途径。离子交换法淡化海水具有处理彻底、成本低、可再生等优势,已在海水淡化预处理、后处理、浓海水中提取化学元素等方面得到应用,具有广阔前景。

With the rapid development of economy in our country, water consumption has increased dramatically. Due to the developed economy, large population and great demand for water resoures in coastal region, there is relatively short of water sources. Seawater desalination will become the important way to resolve the coastal city of fresh water resources shortage. Ion exchange method for seawater desalination has some advantages, such as entire disposal, low cost and renewable, therefore, it has been applied widely in seawater desalination pretreatment, aftertreatmcnt as well as extraction of chemical elements from thick seawater. This method has broad application prospects.
