【摘要】 为了有效地应用絮凝沉淀与中空纤维膜微滤(CMF)组合工艺处理低放射性的含钚废水,对废水处理工艺中的关键运行条件进行了优化:硫酸亚铁的最佳加入量为ρ(Fe2+)=35~60 mg/L,出水pH控制在6.5~9.0,钚去除率大于99.9%。同时还对含U,Am的Pu废水处理实验条件进行了优化,建立了处理含铀、钚、镅的混合废水的实验工艺流程并进行了验证实验。结果表明,采用CMF工艺处理含铀、钚、镅的混合废水,单级处理的总α去除率达到99.87%。更多还原

【Abstract】 The coagulation and microfiltration combined technological process(CMF) was used to treat the low-level radioactive 239Pu wastewater.This paper referred to the effect of correlation parameters on cleaning efficiency,such as the content of Fe2+ and pH of the effluent.The results of test show that the removal efficiency is higher than 99.9% when the content of the Fe2+ is 35～60 mg/L and pH of the effluent is between 6.5 and 9.0.The proof test of the 239Pu wastewater containing 238U and 241Am was done and the integrated experimental technological process is established.The results show that the α removed efficiency of 1 stage is 99.87%.更多还原
