摘要
采用氯化钡-碳酸钠-砂滤固液分离的除镭流程，当每升废水中Bs2＋的投入量为3～5mg，碳酸钠投入量为5mg，可将含镭3．7Bq／L、pH值为6～9的铀水冶厂酸性废水处理到含镭3．7×10－2Bq／L数量级，镭去除率大于90％。
The eliminating radium prdcedure, barium chloride-sodium carbonate-sand filtering, being used,radium can be eliminated to 3' 7 × 10-2 Bq/L order of magnitude from uranium millacid effluents which contain 3. 7 Bq/L. Ra and PH 6~9 when Ba2+ is added by 3~5 mg perlitre,Na2CO3smg. The radium elimination rate is more than 90%.
