摘要
分析了海水淡化的市场和前景,介绍了目前大规模采用的三种常规工艺技术,即多级闪蒸、多效蒸馏和反渗透的现状、技术特点及其发展趋势。最后,根据海水淡化发展的新趋势,介绍了两种比较有发展潜力的新型海水淡化技术即:膜蒸馏技术和正渗透技术,并且分别从技术优势和研究热点方向进行了分析与讨论。
The market and prospects of seawater desalination were analyzed. The progress and technical features were described for the three conventional seawater desalination technologies,i. e.,multi- stage flash,multi- effect distillation and reverse osmosis. Finally,membrane distillation and forward osmosis technologies were introduced based on the new trends of seawater desalination. Their technical advantages and research trends were also discussed,respectively.
