摘    要：研究电渗析处理铀矿冶尾矿水。结果表明,电渗析可以从尾矿水中脱除80%以上的盐分,尾矿水中的盐分大部分是硫酸钙,浓缩后硫酸钙沉淀下来,不会使尾矿池中的尾矿水含盐浓度增高。电渗析方法处理尾矿水,耗电量随尾矿水的浓度变化,得到每吨淡水耗电量为0.5～0.9kW·h。

Abstract: The treatment of tailings water of the uranium mining and metallurgy by electrodialysis is investigated.The results show that the 80% of the salt can be removed from the tailings water by the electrodialysis treatment,the salt in the tailings water is mostly calcium sulfate,calcium sulfate concentrated is precipitated,and the salinity concentration of the tailings water in the tailings pond will not be increased.And power consumption of the treatment of tailings water by electrodialysis is changed with concentration of the tailings water,the fresh water power consumption is 0.5 to 0.9 kW·h·t^-1.
