锅炉水处理技术是通过离子树脂交换法将水中的硬度盐离子即阳离子(如Ca~(2+)、Mg~(2+)、Na~+等)置换清除,以生产出合格的软化水,再将水中的阴离子(如CO_3~(2-)、SO_4~(2-)、Cl~-等)除掉,以生产出合格的除盐水;还通过膜过滤工艺来生产出无硬度低电导率的工业纯水。因此,传统的锅炉化学水处理工艺生产的软化水、除盐水或工业纯水都是为了将进入锅炉前的水质中的杂质离子(阴、阳离子)去除,以达到国家规定的锅炉给水水质标准。但是,实际上水中杂质离子通过化学水处理工艺(阴床、阳床
Boiler water treatment technology is through the exchange of ion resin salt hardness of water ions that are cation (such as Ca ~ (2 +), Mg ~ (2 +), Na ~ +, etc.) to purify to produce qualified demineralized water, Then the anions (such as CO_3 ~ (2 -), SO_4 ~ (2 -), Cl ~ -, etc.) in the water are removed to produce qualified desalinated water; and the membrane filter process is also used to produce the low hardness and low conductivity Industrial pure water. Therefore, the demineralized water, demineralized water or industrial pure water produced by the traditional boiler chemical water treatment process is to remove the impurity ions (anion and cation) in the water quality before entering the boiler in order to meet the national boiler water quality standards. However, in fact, impurity ions in the water through the chemical water treatment process (anion bed, yang bed
