海水淡化及其对经济持续发展的作用

摘要经济增长、人口增加以及水体的污染,导致我国当前淡水资源严重短缺,成为经济持续发展的重要障碍。本文评述了国内外缺水的现状,系统介绍了国内外海水淡化技术的发展形势和应用规模,以及本科研组近年来在海水淡化方面的研发成果。到2009年全世界已有150个国家应用海水淡化技术,数亿人饮用或使用淡化水,淡化水以年增长率10%~12%的速度增加。10年来我国海水淡化厂的投建,以及相关产业迅速发展,使我国成为国际前十大淡化技术应用市场之一。但我国在海水淡化产业方面仍处于初期阶段,设备制造业和大型装置的开发设计能力与国际先进水平差距尚大。还需进一步加大投入,并通过国际合作加快进入国际水准的技术领域和市场竞争。

Abstract： The water resources in China become more stressed due to the continued economy growth and population increase.Water crisis has become the bottleneck for sustainable economy development in some areas in China now.A number of studies have been carried out to meet the gap between supply and demand of water resources.The rapid economic development in China has led to a great progress in desalination in the past 10 years.Desalination developing plans have been made in the related coastal cities/provinces of the Southeast China,which aim to produce about 3 million m~3/d of fresh water in the next 10 years.There is no doubt that the demand for water in China will continue to increase in the foreseeable future. However,status of seawater desalination in China is still at its early stage.A number of important basic technologies and supporting industries have not been well developed yet,and need to be further studied and practiced.
