提出了氢氧化钠法炼锌废电解液苛化处理工艺,确定了工艺参数,通过小型综合实验验证工艺的可行性.结果表明:该工艺再生碱的同时还能去除废电解液中的杂质,1 m3的废电解液可苛化出约28 kg碱,废电解液中铁、铜、镁、锰、镉、铬等重金属的去除率在10%～40%,砷的去除率可达62%,具有较好的净化除杂效果.

In this study,a novel cauticization process of waste electrolye from sodium hydroxide zinc metallurgy was reported and the optimum parameters were determined,and a small comprehensive experiment was carried out.In this process not only alkali was regenerated from waste electrolye,but also the impurity ions in waste electrolye were removed.1 m 3 waste electrolye could regenerate 28 kg alkali.The removal of Fe,Cu,Mg,Mn,Cr,Cd was 10%～40%,especially that the removal of...
