含钴废水处理方法及其研究进展

Research progress on cobalt-containing wastewater treatment

介绍了目前国内外含钴废水的主要处理方法,包括氢氧化物沉淀法、硫化物沉淀法、铁氧体沉淀法、吸附法、离子交换树脂法、溶剂萃取法、膜分离法、生物法等,分析了每种方法的优、缺点及其应用情况,指出多种处理技术的组合工艺将是含钴废水处理的新方向。

Main cobalt-containing wastewater treatment processes currently used in China and abroad were introduced, which includes： hydroxide precipitation, sulfide precipitation, ferrite coprecipitation, adsorption, ion exchange resin, solvent extraction, membrane separation, and biological process. The advantages and disadvantages of each process as well as their application situations were analyzed. It was pointed out that, combined process should be the research direction of cobalt-containing wastewater treatment in the future.
