<p><P>PROBLEM TO BE SOLVED: To provide a treatment method of a plutonium-containing waste liquid, which is capable of accurately decontaminating plutonium in a simple treatment process. <P>SOLUTION: The treatment method of a plutonium-containing waste liquid includes: a step of adjusting the pH of a plutonium-containing waste liquid by an alkali aqueous solution in a settling tank 3; a step of roughly separating the pH-adjusted waste liquid into settlings and supernatant by a centrifugal separator 8; and a step of performing high-order filtration of the roughly separated supernatant by high-order filtering devices 13 and 16 using at least one of a microfiltration membrane (MF membrane) and an ultrafiltration membrane (UF membrane). <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
