摘要
为了研究膜法放射性废水处理系统中超滤预处理单元对放射性废水的净化效果,在实验室采用小型超滤装置,配制含有铁、钴、锰和镍等非放射性核素的模拟放射性废水进行超滤处理实验。实验结果表明:在偏碱性条件下,超滤对模拟废水中的核素均具有较好的截留效果;在废水pH值分别为3.7、9.5、9.2和9.0时,对Fe3+、Co2+、Mn2+、Ni2+的截留率都在95%以上,pH值对于4种核素截留效果的影响是由其水解能力的差异造成的。
In order to reveal the performance of the ultra-filtration adopted in the radioactive wastewater treatment,experiments were carried out on a pilot UF equipment using the wastewater containing the simulated nuclides.Results showed that the nuclides could be rejected by UF efficiently and the rejection ratio is influenced by pH,with different effects on the rejection of Fe3＋,Co2＋,Mn2＋ and Ni2＋.Theoretical calculation was performed to explain the phenomenon and rejection mechanism was interpreted.
