脱除盐水中硫酸盐工艺的研究

Research on the process of removing sulfate from saltwater

比较了几种脱除盐水中SO_(4)^(2-)的方法,介绍了冷冻法脱除盐水中SO_(4)^(2-)的原理及改性反渗透膜法+冷冻法脱除SO_(4)^(2-)工艺在离子膜烧碱生产装置中的应用情况。

Several methods for removing SO2-from brine were compared.The principle of removing SO2-from brine by freezing method was introduced.The application of the combination of modified reverse osmosis membrane method and freezing method for SO2-removal in an ion-exchange membrane caustic soda production plant was also introduced.
