CONTAMINATION WATER PROCESSING METHOD, CONTAMINATION WATER PROCESSING SYSTEM AND SODIUM COMPOUND ADDITION DEVICE USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a contamination water processing method of various kinds of contaminated water capable of facilitating adsorption removal of radioactive nuclide while suppressing effects of coexisting substances other than radioactive substances.;SOLUTION: The contamination water processing method comprises: a pH buffer process for making contaminated water slightly alkaline; an adsorption step for adsorption removing radioactive nuclide contained in the contaminated water after the pH buffer process; and controlling the water quality of the contaminated water so that sodium contained in contaminated water is excessive to calcium before the adsorption step of the radioactive nuclide.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
