摘　　要：渗透汽化(PV)膜分离技术是一种新型膜分离技术,适用于分离恒沸点混合物、近沸点溶液、热敏感性混合物、有机-有机混合物以及水溶液中少量有机物。PV分离水溶液中有机物的工业应用还处于初步阶段,文中从硅橡胶渗透汽化优先透有机物膜的制备条件、工艺应用参数及膜寿命等方面进行综述。膜生产放大和膜寿命是影响该技术推广的重要因素,可以从膜制备和应用工艺方面进行改进。Pervaporation(PV) has been regarded as a promising separation technology in separating azeotropic mixtures, solutions with similar boiling points, thermally sensitive compounds, organic-organic mixtures as well as dilute organics removal in aqueous solution. Industrial application of pervaporation for organics removal in aqueous solution is not widely spread. The preparation condition, process parameters, service life of rubber pervaporation membranes for organics removal in aqueous solution is summarized in this paper. It is considered that the scale-up of membrane fabrication and membrane stability are the important factors affecting the popularization of this technology, and membrane preparation and application process should be improved.
