反渗透对模拟放射性废水中锰的截留性能研究

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

在小型装置上对配制的含锰模拟废水进行处理实验,研究反渗透对放射性废水中核素的截留性能。结果表明:反渗透对锰的截留率受操作压力和回收率的影响甚小,与反渗透脱盐率之间也没有直接的关系。在实验条件下,反渗透对废水中锰的截留率大于95%,满足压水堆放射性废水处理的需要。

In order to reveal the performance of reverse osmosis applied in the radioactive wastewater treatment, treatment experiments are carried out on a pilot RO equipment using wastewater containing manganese nuclide. Results show that the rejection ratio of RO to manganese is almost not influenced by the operation pressure and the ration of reclaiming, and has no direct relation with the salt rejection ratio. The ratio of manganese rejection is more than 95% and can meet the requirement on the disposal of radioactive wastewater produced by oressurized water reactors.
