关注了一种以太阳能为驱动热源,基于空气隙膜蒸馏过程的新型海水淡化技术(SP-AGMD),介绍了该技术涉及的膜组件和太阳能集热装置的材质、形式、特点和研究概况,并对比分析了各种膜组件和太阳能集热装置的优势及存在的不足,对国内外的最新研究进展作了重点讨论。将太阳能引入膜蒸馏海水淡化过程大大降低了能耗,有效避免了二次污染而且最大程度节约了运行费用。认为该技术尚处于实验室研究和小型示范阶段,将膜组件与太阳能集热装置更加高效的耦合,进一步降低系统总能耗将是太阳能空气隙膜蒸馏领域的重要方向。

A new desalination technology based on the solar power as the heat energy source and air gap membrane distillation（SP-AGMD） was presented.The related texture,configurations,characteristics and the development overview of membrane module and solar heat collectors were reviewed.And the advantages and shortcomings of various membrane modules and solar heat collectors were analyzed.The current research progress at home and abroad was the center topic in this review.The energy consumption,the cost as well as the secondary pollution was considerably decreased because of incorporation of solar power into membrane distillation desalination process.Although SP-AGMD process was still at the laboratory and small-scale demonstration stage at the moment,it will be promising if the effective coupling between membrane modules and solar heat collectors and the further decrease of energy consumption of the system were achieved.
