摘要:

目标选择性填充床电渗析(Ion exchange selective electrodialysis,ISED)是一种利用离子交换树脂填充提高电渗析在特定条件下离子分离效率的水处理技术。其具有相对较高的能源效率以及无需树脂酸碱再生的优势,现已在超纯水制备以及电力、制药、汽车等行业的特定废水处理方面得到应用。在对离子交换电渗析(Ion exchange electrodialysis,IXED)与ISED两种工艺进行区分的同时,全面总结并讨论了目标离子在IXED与ISED两种工艺离子运动与分离过程所涉及的理论、机制与模型。在此基础上对IXED与ISED两种工艺结构与技术发展现状进行归纳,讨论并分析了ISED技术在地下水、工业废水中离子分离与回收等方向的研究进展。最后,从ISED的树脂、膜材料、运行方式3个方向对ISED技术选择性分盐未来的发展方向进行展望。

Abstract:

Ion exchange selective electrodialysis(ISED) is a water treatment technique that uses ion exchange resin filling to improve the efficiency of ion separation by electrodialysis under specific conditions. With relatively high energy efficiency and no need for resin acid-base regeneration, ISED has been now used in ultra-pure water preparation and specific wastewater treatment in the electric power, pharmaceutical,automotive and other industries. While distinguishing between ion exchange electrodialysis(IXED) and ISED, this paper comprehensively summarized and discussed the theory, mechanism and model of ion movement and separation of target ions in IXED and ISED processes. On this basis, the development status of IXED and ISED process structures and technologies was summarized, and the research progress of ISED technology in the direction of ion separation and recovery in groundwater and industrial wastewater was discussed and analyzed. Finally, the future development direction of selective salt separation by ISED technology was prospected from three aspects of resin,membrane material and operation mode.

Key words: ion exchange selective electrodialysis, selective separation, soluble target ions, water treatment
