Waste liquid treatment method and waste liquid treatment equipment

摘要

To provide a waste liquid treatment method and the like that can efficiently carry out the removal of metal components for a waste liquid containing a metal component (for example, a radionuclide such as radioactive cobalt) as a removal target.SOLUTION: In the waste liquid treatment method according to the embodiment, the removal target is removed by treating the waste liquid containing the metal component as the removal target. The waste liquid treatment method has a normal salt addition step (ST40) and a cation exchange step (ST10). In the normal salt addition step (ST40), a normal salt is added to the waste solution. In the cation exchange step (ST10), the waste liquid to which the normal salt is added in the normal salt addition step is passed through a cation exchange resin.SELECTED DRAWING: Figure 1
