摘　　要：以含氟含铀废水为研究对象,开展了石灰乳沉淀除F效果验证,U共沉淀效果研究,石灰乳量与F、U沉淀效果研究等试验工作,明确在本实验体系下,U的共沉淀效率为87.0%~99.8%,回收率为93.58%~115.75%,并通过实验对核燃料循环设施废水处理工艺的改进提出了相关建议。Wastewater containing fluoride and uranium is used to study the fluorine removal effect and the uranium co-precipitation effect with lime-milk as precipitant. The relationship between the quantity of lime milk and the coprecipitation effects of fluorine and uranium is investigated. The uranium co-precipitation efficiency and the uranium recovery rate are 87. 0%- 99. 8% and 93. 58%- 115. 75%,respectively. Some suggestions about the improvement of treatment process for radioactive wastewater in he nuclear fuel cycle facilities are put forward as well.
