摘　　要：反渗透是海水淡化的主流工艺,但是反渗透在生产淡水的同时会产生大量的浓水。浓水中含有大量富集浓缩的稀有金属。本文对浓水中回收金属资源的预处理方法和预浓缩技术工艺原理及技术特点进行了概述,在此基础上,对浓水中典型金属(如钠、镁、锂及锶)回收研究进展进行了讨论。Reverse osmosis is the mainstream process for seawater desalination,but it produces a large amount of concentrated brine while producing fresh water.Concentrated brine contains a large amount of enriched rare metals.This article provides an overview of the pre-treatment methods,process principles,and technical characteristics of metal resource recovery in concentrated brine.Based on this,the research progress on the recovery of typical metals(such as sodium,magnesium,lithium,and strontium)in concentrated brine is discussed.
