摘要
随着工业化的推进,大量工业废水的产生给环境带来了严重威胁,废水的资源化利用势在必行.双极膜电渗析(BMED)以其独特的水解离和离子转移机制,已经被应用于包括废水处理和资源化在内的诸多领域,可以富集离子态的无机或有机污染物并产生化学品以实现资源回用.文章介绍了BMED工艺的装置组成和工作机理,并对双极膜的制备方法、废水资源化方面的应用和改性方法进行了综述,最后提出了现阶段制约BMED工艺发展的因素,并对此工艺未来的发展趋势进行了展望.
Abstract
With the advance of industrialization,the production of large amount of industrial wastewater has brought serious threats to the environment,and the resource utilization of wastewater is imperative.Bipolar membrane electrodialysis(BMED)has been applied in many fields,including wastewater treatment and resource recovery,because of its unique mechanism of water dissociation and ion transfer.It can enrich organic or inorganic pollutants in ionic state from wastewater and produce chemicals to realize resource recovery.Here,the reactor composition and working mechanism of BMED process are introduced,and the preparation method of bipolar membrane,the application of wastewater recycling and modification methods are reviewed.Finally,the factors restricting the development of BMED process at present are put forward,and the development trend of BMED process in the future is forecasted.
