| 摘 要： | 通过热动力学分析，理论计算和实验，确定在碱性条件下用NaClO作氧化剂，Na2S和FeSO4作还原剂处理混合电镀废水的工艺流程，并通过计算和实验确定了Na2S和FeSO4的最佳药剂比：Na2S为80%～90%，FeSO4为10%～20%，Na2S FeSO4比单独使用FeSO4少产生60%～70%的污泥，该工艺在实际工程运行过程中效果良好。

| Abstract: | A technological process for the disposal of mixed electroplating wastewater under the alkaline condition was chosen by thermodynamic analysis, theoretical calculations, and experiment investigations. In this process, NaClO was chosen as oxidant, Na2S and FeSO4 as reducers. The optimal ratio of Na2S and FeSO4 was determined as Na2S 80%-90%, FeSO4 10%-20%. Using Na2S and FeSO4 as oxidants can reduce the sludge quantity by 60%-70% comparing with using FeSO4 only. A real project by this technology has already obained good results. |
