摘　　要：简要介绍了锂电三元前驱体废水回收钴的背景和工艺,并结合某锂电新材料企业前驱体废水回收镍钴工程实例进行具体分析。处理前,该企业硫酸铵溶液中含钴量为60~120 mg/L,含镍量为50 mg/L,铵根为25 g/L,碳酸氢根含量为40 g/L。采用脱碳塔→多介质过滤器→活性炭过滤器→螯合树脂回收镍系统等工艺处理后,镍离子质量浓度<3 mg/L,钴离子质量浓度<5 mg/L。This paper briefly introduces the process of recovering cobalt from the precursor wastewater of lithium battery,and makes a specific analysis based on the project of recovering nickel and cobalt from the precursor wastewater of a lithium battery new material enterprise.Before treatment,the cobalt content in the ammonium sulfate solution of the enterprise is 60~120 mg/L,the nickel content is 50 mg/L,the ammonium content is 25 g/L,and the bicarbonate content is 40 g/L.After the process of decarburization tower→multi-media filter→active carbon filter→chelating resin nickel recovery system is adopted,nickel ion is less than 3 mg/L and cobalt ion is less than 5 mg/L.
