摘要:

在电场作用下,双极膜内的水能快速解离产生H+和OH-,这一电化学特性使双极膜电渗析(BMED)逐渐发展为一种新型膜分离技术。首先介绍了BMED的基本工作原理,综述了其发展历程,接着介绍了近年来其在酸碱生产、污染控制、与其他化工技术耦合作用等方面的研究进展,最后提出目前应用中存在的问题,并对BMED的未来发展进行了展望。

Abstract:

Under the effect of electronic field, the water in the bipolar membrane is rapidly dissociated to produce H+ and OH-. This electrochemical property leads to the development of bipolar membrane electrodialysis(BMED) as a new membrane separation technology. This paper firstly gave a brief review on the basic operating principles of the BMED technology and summarized its development. Then the application and progress of the acid and alkali production, pollution control, coupled with other separation technologies in chemical engineering were reviewed and discussed. Finally, some problems were put forward together with the prospects for further development.

Key words: bipolar membrane, electrodialysis, resource recovery, zero pollution emissions
