摘要： PROBLEM TO BE SOLVED: To easily separate and collect purified water from which solid matters and radioactive substances are efficiently removed without increasing secondary waste quantity when treating radioactive waste solution in which contaminated water and sludge coexist, and also to collect the solid matters as dry matter allowed to be stably stored for a long period.SOLUTION: A decontamination waste liquid treatment apparatus for treating decontamination waste liquid contaminated with radioactive substances containing soluble contaminant and granular suspended matter includes: a decontamination waste liquid tank filled with the decontamination waste liquid contaminated with the radioactive substances containing the soluble contaminant and the granular suspended matter; a filter unit for separating the decontamination waste liquid from the decontamination waste liquid tank into filtered residue and filtered water; a reverse osmosis membrane purification unit for separating the filtered water from the filter unit into concentrated water and purified water; and a drying unit for drying and solidifying the concentrated water supplied from the reverse osmosis membrane purification unit.
