摘要
本文研究了粉状氢氧化镁和以白云石为原料制备的氢氧化镁乳液处理含铀放射性废水的条件 ,试验结果表明 ,氢氧化镁处理剂具有良好的除铀效果 ,在所选择的条件下 ,能将废水中的含铀量降至 0 .0 5 mg/L以下 ,且 p H值控制在 6～ 9之间 ,达到国家环保要求。用氢氧化镁除铀 ,方法简单 ,除铀率高 ,特别适合于酸溶浸铀后 ,地下低放射性含铀废水的处理。
The magnesium oxide slurry made of magnesium gydoxide powder and dolomite was used to treat the radioactive wastewater bearing uranium leached by acid. The method have good effect on removing uranium. Under the appropriate condition, the content of uranium in wastewater was reduced to 0.05mg/L and pH was controlled in the range of 6 to 9, which meet the demands of the state environmental protection. The procedure is very simple and the removal ratio of uranium is high.
