海水淡化工艺及发展趋势

摘要

As the development of society economy and the increase of the population,the shortage of water resource became a prominent problem and a global issue.Various countries had turned their attention to the sea to search freshwater resources,and the development of seawater desalination technology was more and more urgent.According to the progress of the development of seawater desalination technology,the present situation and the existing problems of major technology involving distillation method and membrane method were reviewed,a tendency of the development about the seawater desalination technology was put out to provid a new train of thought for the seawater desalination technology.%随着社会经济的发展和人口数量的增长,水资源紧缺问题日益突出并已成为全球性的问题。在寻求淡水资源方面,各国纷纷将目光投向大海,海水淡化技术的发展愈显紧迫。针对国内外海水淡化工艺发展概况和进展,本文介绍了蒸馏法、膜法等主要工艺发展现状以及存在的问题,指出了海水淡化工艺今后发展的趋势和方向,为海水淡化工艺技术提供新思路。
