| 摘 要： | 冷冻盐析法处理硫酸酸洗废液工艺原理和规程是依据硫酸亚铁溶解度－硫酸浓度－溶液温度三个主要参数的变化规律，特别是在０℃以下的变化规律进行研究和实际应用，做到废酸液不外排，分离后的酸液继续使用。可节省硫酸４０％～５０％。

| Abstract: | This principle and process is researched and used according to the rule of three data of FeSO4solubility -H2SO4-solution temperatare, especially below 0℃. So waste acid needn't be left out, the acid solutioncan be continuously used after separation. Fourty～fifty percent of sulphuric acid can be saved. |

| Keywords: | treatment of sulphuric acid environmental protection |
