摘　　要：采用Span80-P204-煤油液膜体系,对江西某稀土分离厂所排放的稀土废水进行处理,经测定该废水含Re3+的浓度在100～300mg/L.经液膜处理后,废水中Re3+的浓度低于1mg/L,达到国家排放标准.同时经浓缩提取后稀土可作为原料,返回稀土分离厂进行重新利用.Span80-P 204 -kerosene liquid membrane system is used to treat rare earth ions removed by a rare earth ions separating factory in Jiangxi.Through determination the concentration of Re 3+ was between100g/L and300mg/L.After using the liquid membrane to treat it,the concentration of Re 3+ in the wastewater can reach the state's removal standard.Meanwhile,through concentrated extracting,the rare earth can be made into raw material,return to the separating factory and can be reused.
