PURPOSE:To dispense with a heat source and to improve the recovery rate of a distillation product by using a hydrazine compd. as a detergent, decomposing the hydrazine generated as a radioactive waste liq., and heating the waste solvent with a microwave. CONSTITUTION:The impurities contained in the waste liq. is removed by the detergent consisting of a hydrazine compd. in a washing device 1. A waste solvent feed system 2, a detergent feed system 3, a waste solvent outlet pipe 4, and a washing waste liq. outlet pipe 5 are connected to the device 1, and a waste liq. decomposing device 6 and the discharge pipe 7 for generated gases are connected to the pipe 5. The waste solvent is washed in the washing device 1, supplied to a rectification device 8 through the waste solvent outlet pipe 4, heated by the microwave supplied from a microwave generator 9 and a waveguide 10, and evaporated. The effective components in the rectified waste solvent is recovered in the first and the second recovery devices 12 and 14 through discharge pipes 11 and 13. The residue in the rectification device 8 is treated in a residue treating device 16 through a residue discharge pipe 15.
