摘　　要：研究一段高温添加消石灰+二段高温加废电解液+三段低温添加活性炭的新型净化方法有利于硫酸锌溶液中非常规元素Si、As、Sb等的深度脱除、有机物脱除及钙镁结晶物实现深度脱除,进而实现硫酸锌溶液的深度净化,提高锌片质量,降低锌片直流电单耗。实验研究结果表明,净化后溶液中Si≤20 mg/L、Sb≤0.02 mg/L,As≤0.01 mg/L、TOC≤100 mg/L。This paper study new purification method of adding lime at high temperature in the first stage,adding waste electrolyte at high temperature in the second stage,and adding activated carbon at low temperature in the third stage,the calcium-magnesium crystal can be removed deeply,and then the zinc sulfate solution can be purified deeply,the quality of zinc flake can be improved,and the DC power consumption of zinc flake can be reduced.The experimental results show that Si≤0.01 mg/l,SB≤0.02 mg/l,As≤0.01 mg/l and Toc≤100 mg in the purified solution.
