过硫酸铵含铜废液预处理工艺改造

The Reconstruction of the Pretreatment Technique of Ammonium Persulfate Spent Solution

采用离子交换工艺对过硫酸铵含铜废液预处理原有工艺进行改造,改造后降低了废液预处理成本,减少二次污染,提高铜资源的回收率,达到综合利用的目的,具有很高的环境效益及经济效益。

The reconstruction for the pretreatment technique of ammonium persulfate spent solution is carried out with ionexchange,after which the pretreatment cost for the spent solution is lowered,the secondary pollution is reduced and the reclaim ratio of copper resource is increased,so that the aim of comprehensive utilization have been attained and good environmental and economic benefits have also been obtained.
