摘　　要：电镀含镍废水中含有大量的金属镍,按照传统的化学沉淀法处理,不但浪费资源,而且出水难以达到新的排放要求。本文介绍了利用离子交换技术实现电镀含镍废水现场回收技术的原理、工艺流程、操作方式,并通过一个应用实例说明了该技术的实现效果,既可以回收硫酸镍作为生产原料,减少原料投入成本,又可提升企业清洁生产水平,降低物料单耗,取得很好的经济效益和环境效益。There is a large amount of nickel in nickel containing electroplating wastewater, which is not only a waste of resources,but also difficult to meet the new emission requirements, according to the tradi- tional precipitation treating method. In this paper, the principle, process flow, operation mode of the on- site recovery technology for treating nickel containing electroplating wastewater by ion exchanging method were introduced, and an application example was given to illustrate the real effect of this technology, which could not only recover the nickel sulfate as raw material, reduce raw material input cost, but also improve the cleaner production level of enterprise, reduce unit material consumption, achieving good economic and environmental benefits.
