PROBLEM TO BE SOLVED: To provide a radioactive wastewater treatment method and a treatment device for the same capable of reducing generation of concentrated water to be treated by increasing a concentration thereof and continuously treating the wastewater.;SOLUTION: Wastewater containing radioactive substances is supplied to a wastewater reception tank 2. The wastewater in the wastewater reception tank 2 is then: supplied to a reverse osmosis membrane treatment device 5 by a wastewater supply pump 4 through a wastewater supply pipe passage 3 connected to the wastewater reception tank 2; and separated into permeated water and concentrated water by the reverse osmosis membrane treatment device 5. A portion of the concentrated water separated by the reverse osmosis membrane treatment device 5 is discharged through a concentrated water transfer pipe passage 7 connected to a concentrated water discharging side of the reverse osmosis membrane treatment device 5. The remaining concentrated water separated by the reverse osmosis membrane treatment device 5 is circulated to an upstream side thereof through a circulation pipe passage 8 branched from the concentrated water transfer pipe passage 7.;COPYRIGHT: (C)2014,JPO&INPIT
