海水是地球上存量最大的资源。开发和利用海水淡化技术是未来开发新水源、解决全球性水资源危机的重要途径之一。早在400多年前就有人提出海水淡化的构想。进入20世纪后,海水淡化技术随着水资源危机的加剧而迅速发展。1970年以来,由于水资源匮乏,许多沿海国家加快了海水淡化的产业化。现今中东国家70%的淡水来自海水淡化。
Sea water is the largest stock of resources on Earth. Developing and utilizing desalination technology is one of the important ways to develop new water sources and solve the global water crisis in the future. As early as 400 years ago, some people proposed the idea of seawater desalination. After entering the 20th century, desalination technology developed rapidly as the crisis of water resources intensified. Since 1970, many coastal countries have accelerated the industrialization of seawater desalination due to lack of water resources. Today, 70% of freshwater in the Middle East comes from seawater desalination.
