摘　　要：介绍了一种蒸氨-沉淀-电沉积的新型碱性蚀刻废液处理工艺,研究了加碱量、蒸氨温度对蒸氨铜直收率的影响及电流密度对旋流电解效率的影响,选定了较佳的工艺参数,试验获得了符合标准的阴极铜。A new process of handling alkaline etching waste liquid of ammonia-precipitation-electro deposition is introduced,the influence of alkali amount and ammonia evaporation temperature on the straight yield of ammonia vapor copper and the impact of current density on the efficiency of cyclone electrolysis are studied.Optimal process parameters are selected.And the cathode copper which conforms to the standard is obtained from the experiment eventually.
