摘要
随着工业绿色转型与循环经济发展,工业废水处理正从末端污染控制向资源化利用转变,高选择性、低能耗地分离与回收废水中的有价物质成为近年来工业废水处理技术的热点研究方向之一。电渗析(Electrodialysis,ED)作为一种基于电场力驱动的膜分离技术,已被广泛应用于对工业废水的分离、浓缩和循环利用等,且电渗析在选择性分离回收工业废水中有价物质方面展现出显著潜力。系统阐述了电渗析选择性分离与回收工业废水中有价物质的技术原理,并依据工业废水特征与有价物质的种类与来源,详细评述了常规电渗析、电去离子(EDI)、双极膜电渗析(BMED)、倒极电渗析(EDR)以及选择性电渗析(SED)等关键技术在分离回收重金属离子、盐分及酸碱等物质方面的重要突破与研究进展。最后,从离子交换膜种类、工艺耦合、引入智能控制等方面提出了电渗析技术未来发展方向。
With the green transformation of industry and the development of circular economy,industrial wastewater treatment process is transforming from end-of-pipe pollution control towards resource recovery.The high-selectivity,low-energy consumption separation and recovery of valuable substances from wastewater have become a key research focus in industrial wastewater treatment technology in recent years.Electrodialysis(ED),as an electric fielddriven membrane separation technology,has been widely applied for the separation,concentration,and recycling of industrial wastewater.Furthermore,ED demonstrates significant potential for the selective separation and recovery of valuable substances from industrial wastewater.This paper systematically introduced the technical principle of selective separation and recovery of valuable substances from industrial wastewater by electrodialysis.Based on the characteristics of industrial wastewater and the types and sources of valuable substances,important breakthroughs and research progress achieved by key technologies,such as conventional electrodialysis,electrodeionization(EDI),bipolar membrane electrodialysis(BMED),electrodialysis reversal(EDR),and selective electrodialysis(SED)in separating and recovering heavy metal ions,salts,and acids/bases were reviewed.Finally,future research directions for electrodialysis technology were proposed,focusing on areas such as ion-exchange membrane varieties,process integration,and the introduction of smart control systems.
