电渗析在不锈钢酸洗废水中回收镍的应用

Application of electrodialysis in recovery of nickel from stainless steel pickling wastewater

不锈钢在冶炼和加工的过程中,会产生一层氧化膜,需要通过酸洗工艺进行处理,而产生的不锈钢酸洗废水中含有大量的重金属离子,尤其是镍离子。本文以离子交换膜为例,探讨了从不锈钢酸洗废水中回收镍的方法,希望能够为相关的工作提供一定的参考。

In the process of smelting and processing of stainless steel, a layer of oxide film is produced, which needs to be treated by acid pickling process. The stainless steel acid pickling wastewater contains a large number of heavy metal ions, especially nickel ions. Taking ion exchange membrane as an example, this paper discussed the method of recovering nickel from stainless steel pickling wastewater, hoping to provide some reference for related work.
