摘要	The rapid development of nuclear technology has led to more liquid organic radioactive wastes. Different from the regular aqueous radioactive wastes, these liquids possess a higher hazard potential and cannot be disposed through the conventional methods due to their radioactivity and chemical nature. Spent extraction solvent is a kind of common liquid organic radioactive wastes. In this work, tri-butyl phosphate (TBP), which is more difficult to degrade in the spent extraction solvent, was used as the model compound. Influences of reaction conditions on total organic carbon (TOC) removal and the volume percentage of each gas component under supercritical water oxidation (SCWO) were studied. The SCWO behaviors of spent extraction solvent simulants were studied under the optimal conditions derived from the TBP experiment. The SCWO experiments were studied at 400-550 degrees C, oxidant stoichiometric ratio of 0-200%, feed concentration of 1.5%-4% and pressure of 25 MPa for 15-75 s. The results show that the TOG removal of the simulants was greater than 99.7% and CH4, H-2 and CO were not detected at 550 degrees C, 25 MPa, oxidant stoichiometric ratio of 150%, feed concentration of 3%, and residence time of 30s.
