摘　　要：　本文依据醋酸铜氨废液的性质,利用加热吹脱和投入一定量的酸碱等方法,使其大部分醋酸铜氨络离子转化为硫酸铜.残余废液再经调节pH值,加入硫化钠溶液等方法进一步处理,使其原含铜量高达110 3克/升的醋酸铜氨废液经处理后达到0 15毫克/升以下,除铜率达99 9%.According to the properties of the waste acetic acid cuprammonia, most of the complex ions in the waste solution can be changed into cupric sulphate by heating blow and taking off and adding quantitative acid or aikali. the rest of the waste solution can be treated by adjusting pH, adding solution of sodium sulphide. the content of copper in the waste solution reduced to 0\^15mg/L from original 110\^3g/L. The ratio of removing copper is 99\^9%.
