摘要
本文阐述了用氯化钡－石灰沉淀法从七四一矿水冶厂尾矿库外排废水中去除镭、锰等超标元素的试验结果。处理后镭、锰含量分别小于１．１１Ｂｑ／Ｌ、２ｍｇ／Ｌ，ｐＨ值为６－９，达到了国家规定的排放标准。
The paper describes the tested results of disposal of the tailings pond effluents at the uranium mill of Mine No. 741 by the barium chloride-lime precipitation process for removal of radium, manganese and other elements. Through disposal the contents of Ra and Mn can be decrease to less than 1. 11Bq/L and ling/L respectively, and pH value can reach 6 to 9,which meet the permitted state standards for discharge.
