摘　　要：研究了从镀锌工业废水中回收的锌盐用于皮革染色的可能性,以及与之相适应的镀锌废水处理方法。研究结果表明:回收的硫酸锌对皮革的固色有较好的效果,染料的残留率低至18%,并优于甲酸固色,实现废弃物资源化利用,变废为利。与之相适应的镀锌废水处理方法可选择离子交换法。The application possibility of reclaimed zinc salt in dyeing process which was recovered from the industrial zinc - plating effluent, as well as the suitable zinc - plating effluent treatment method was investigated. The results show that the reclaimed zinc sulfate can be preferable used in leather dyeing and has good color fixing capacity. The residue of dyestuff is decreased to 18% which is better than that of fixation by formic acid. The discarded zinc salt can successfully be recycled and reused for leather production. Ion exchange method can be adopted as the suitable treatment of zinc - plating effluent.
