摘　　要：以MgCl2作为助剂,采用不同相对分子质量的阳离子聚丙烯酰胺(PAM)对低放含钚废水进行絮凝处理,以钚去除率为评价指标,确定较优絮凝剂及其最佳絮凝条件,对絮凝过程中产生的放射性泥浆体积和沉渣量进行研究,并与传统无机絮凝剂进行比较。实验采用有机絮凝法处理后的废水中钚放射性浓度低于1 Bq/L,钚去除率大于95%。结果表明,该法对于低放含钚废水的有效净化处理具有广阔的应用前景。This paper studied the treatment of low-level radioactive wastewater containing Pu by flocculation processed.The Pu removal efficiencies were investigated using cationic polyacylamine（PAM） with different molecular weights in the presence of MgCl2.The parameters affecting removal rate,such as flocculant dose,solution pH and organic matter were studied.The optimum conditions are the PAM dose of（0.2-1.2）×10-6,MgCl2 dose of 0.8 g/L,and a pH of 12.The content of plutonium in effluent is below 1 Bq/L after treatment,and the removal rate of Pu is higher than 95%.The results show that this method has a significant potential in treating low-level radioactive wastewater containing Pu.
