摘要
介绍了二次回流技术在云南锡业股份有限公司铜业分公司铜冶炼污水处理工艺中的应用, 提 高了石灰乳在污水处理过程中的利用率, 中和渣量明显减少, 处理后的回用水可达到《 铜镍钴工业污染排放 标准》 GB25467-2010）进行回用.
The p aper introduces the application of secondar backflow technolog in copper smelting effluent disposal of Copper branch office of Yunnan Tin Group, the utilization of lime milk can be improved in the period of effluent disposal, and the amount of neutralized slag will be obviously reduced. After disposal, the reclaimed water can meet the requirement of Emission Standard of Pollutants for Copper, Nickel, Cobalt Industr^^ for reuse.
