摘要
简述了双极膜的水解离电渗析及双重电荷排斥性能。介绍了双极膜在含氟废液的处理、有价氟的回收应用、垃圾发酵连续制备有机酸、脱除烟气中的SO2气体、水处理以及双极膜蓄电池等方面的应用现状及前景。双极膜作为一种新型膜,以其水解离电渗析的独特优点,为解决环境工程中存在已久的一些技术难题提供了许多新的思路和解决办法。巧妙地利用双极膜与单极膜的组合,可以设计出许多工艺。双极膜在环境工程中的应用研究值得引起重视。
The paper described the basic characteristic of bipolar membrane（BPM）,including hydrolysis electrodialysis and double charge rejection.The applications and prospects of the BPM in treating fluorine wastewater,recycling of valuable fluorine,preparing organic acids continuously with garbage by fermenting,removing SO2 of the flue gas,water treatment and BPM batteries were introduced.BPM was used as new membrane,with many unique advantages such as hydrolytic dissociation electrodialysis.So it provided many new ideas to solve the existing problems in environmental engineering.Combining BPM and single membrane can design many processes cleverly.Application of the BPM in environmental engineering was worth to pay attention.
