摘要
海洋中除含有地球上绝大部分的水资源外,还含有巨量的矿物资源.目前,从海水中获取的资源较为单一,易造成浪费,同时也对海洋生态产生不利影响.归纳分析了海水淡化副产物浓海水中的主要资源、开发方法及未来发展方向.重点关注浓海水中钠、钾、镁、锂、铀和溴的资源开发工艺和发展现状,分析总结相关工艺和技术的发展趋势,并介绍了中国现有的海水综合利用工程.随着中国循环经济和绿色海洋经济发展理念的实施,浓海水中矿物资源的有效利用和开发必将成为各种资源的新来源.
Abstract
In addition to containing the vast majority of Earth's water resources,the oceans also hold huge amounts of min-eral resources.At present,the resources obtained from seawater are relatively single and prone to waste,while also having adverse effects on marine ecology.The main resources,development methods,and future development directions of concen-trated seawater,a byproduct of seawater desalination were summarized and analyzed.The resource development processes and current status of sodium,potassium,magnesium,lithium,uranium,and bromine in concentrated seawater was focused,the development trends of related processes and technologies were analyzed and summarized,and the existing seawater com-prehensive utilization projects in China were introduced.With the implementation of the development concept of circular economy and green marine economy in China,the effective utilization and development of mineral resources in concentrated seawater would inevitably become new source of various resources.
