稀土废水处理技术及资源化利用研究进展

摘要

详细综述了国内外稀土废水处理技术及综合利用进展，并提出化学沉淀法-电还原法作为稀土废水后续处理，旨在回收稀土氧化物的同时，进一步降低氨氮的浓度，无论从环境还是经济角度考虑，都有现实及深远的意义。%Rare-earth separation wastewater processing and comprehensive utilization technology progress at home and abroad are described in detail. The chemical-electrolysis process for the treatment of rare-earth separation wastewater is put forward, so that rare earth resources in wastewater could be recycled as more as possible and the concentration of ammonia could be reduced at the same time. It has far-reaching practical significance from the aspects of environ-ment or economic.
