摘要
本文通过分析纯水的电离,讨论了普通电渗析(ED)和填充床电渗析(EDI)中水的电离现象及其相关 机理。EDI过程中水电离产生的H+和OH-离子可以自再生离子交换树脂。文中简单介绍了已得到产业化的EDI 技术和正在推广中的离子交换树脂的电再生技术。
This article analysed water dissociation and its relating mechanism in the ED and EDI processes. The H + and OH-ions producing by water dissociation may self-regenerate ion-exchange resins. Two applications are introduced briefly; the developed EDI technology and the spreading electro-regeneration technology of ion-exchange resins.
