Abstract:

Seawater desalination technology is one of the important ways to solve water shortage, and its technology and industry are relatively mature. Abroad, 62% of desalinated water is used for people to drink, others used for the industry, agriculture, tourism and military. So many coastal countries are paying more and more attention to desalination. The state-of-the-art and status quo of seawater desalination technology in the world was analyzed and current gaps by a comparison between China and other countries with advanced seawater desalination technology were discussed. Combining seawater desalination industrial development and the background of "peak carbon emissions, carbon neutrality", and the future development trend of seawater desalination was also discussed and prospeced.

Key words: seawater desalination, tech industry, reverse osmosis, distillation

摘要：

海水淡化是解决水资源短缺的重要途径，海水淡化技术、产业已经成熟，国外62%的淡化水用于市政供水，其余满足工业、农业、旅游业及军事等方面需求，越来越得到一些沿海国家的高度重视。分析了国内外海水淡化技术及产业现状，讨论了与国外相比，我国海水淡化技术存在的差距。结合产业发展和“碳达峰、碳中和”背景，对海水淡化技术产业今后的发展趋势进行了探讨和展望。
