电去离子(EDI)高纯水新技术及其研究进展

The Production of High - purity Water by Electrodeionization: A New Technology and Its Study Advance

介绍了ＥＤＩ过程的脱盐机理，分析并提出了过程的主要强化途径。阐述了ＥＤＩ的特性及“树脂电再生”等特征及其与电渗析（ＥＤ）过程的区别。介绍了国内外ＥＤＩ的研究进展与应用概况。

The Principle of desalination in the electrodeionization is introduced. Several methods are put forward to improve the Process. The unique 'electroregeneration' of the resins in the EDI and the difference between EDI and ED in V - I and pH- I characteristics are expounded, the general situation of the advance of the study on EDI and its application are also desctibed.
