Research on Rejection Performance of Reverse Osmosis to Nickel in Simulated Radioactive Wastewater

摘要: 为了研究反渗透对放射性废水中核素的截留性能,配制含镍的模拟废水在小型装置上进行处理实验。结果表明:反渗透对于镍的截留率受操作压力和回收率的影响甚小,且与反渗透脱盐率之间也没有直接的关系,在实验条件下反渗透对废水中镍的截留率在95%以上,能够满足压水堆放射性废水处理的要求。

Abstract: In order to reveal the rejection performance of the reverse osmosis applied in the radioactive wastewater treatment,treatment experiments were carried out on a pilot reverse osmosis equipment using wastewater containing nickel nuclide.Results showed that the rejection ratio of reverse osmosis to nickel was almost not affected by the operation pressure and the ratio of reclaiming,and had no direct relation with the salt rejection ratio.The ratio of nickel rejection reached 95% in the experiment condition and could meet the requirement on the disposal of radioactive wastewater produced by nuclear powered installations.
