| 摘 要： | 离子交换除盐水处理中，离子交换树脂的再生是关键的一步。用HCl再生氢型强型性阳离子交换树脂存在着一些不足之处，因此可考虑采用H2SO4代替HCl作再生液。本文就些阐述了H2SO4再生氢型强酸性阳离子交换树脂的工艺步骤，并针对在再生过程中出现的CaSO4结晶，确定了适宜的操作条件。

| Abstract: | The recovery of ion exchange resin is a vital step in the process of water treatment that uses ion exchange to get rid of salt from water. Applying hydrochloric acid to recover the hydro\|strong acidic cation exchange resin has some defects, so we can use sulfuric acid to take the place of hydrochloric acid. This paper illustrates the process of the recovery of hydro\|strong acidic cation exchange resin with sulfuric acid and decides the suitable working conditions in accordance with the crystallizing of calcium sulfate. |
