【摘要】 介绍用絮凝沉淀并结合中空纤维膜微滤组合工艺（CMF）处理含铀钚镅的低放水平废水。叙述了一体化中空纤维膜废水处理实验装置在废水处理中的固液分离、去污效果,及两种清洗方法对微滤膜通量的恢复等。CMF工艺对²⁴¹Am、²³⁹Pu废水的去污率均大于99.9%,对含贫化铀废水去污率大于99%,平均浓缩倍数为190,为放射性废水的处理提供了一种新的方法。更多还原

【Abstract】 The coagulation and microfiltration combined technological process（CMF） is used to treat the low-level radioactive wastewater.This paper referred to liquid-solid separation and decontamination factor in the technological process.On addition a comparison is completed about the cleaning efficiency using the chemical method and the physical method.The results of test show that the removal efficiency of ²³⁹Pu or ²⁴¹Am was higher than 99.9%.To treat wastewater containing lean uranium,the effluent is below 7.4μg/L（0.11Bq/L） and the removal efficiency is higher than 99.0%.The results of test show that the CMF process has an excellent ability in treating the low-level radioactive wastewater.更多还原
