【摘要】 介绍在传统的弱、强阳床生产脱盐水的工艺中，强酸型离子交换树脂失效后实际变为Na型离子交换树脂，入口水改为生水，使Ca2+、Mg2+与Na+、K+进行交换，从而可副产软化水。更多还原

【Abstract】 This paper discusses a traditional demineralized water process used the weak or strong canon exchanger. Strong-acid ion exchanger becomes Na-type exchanger when the exchresin losts its efficacy. Then feed the fresh water into the exchanger, the exchange between Ca2+,Mg2+, Na+ and K+ ions will take places, the by-product, demineralized water, can be produced.更多还原
