Description

technical field [0001] The invention relates to the technical field of radioactive organic waste liquid treatment, in particular to a radioactive organic waste liquid treatment device and a method thereof. Background technique [0002] With the rapid development of nuclear power, a large amount of organic waste liquid will be produced in related nuclear activities and nuclear scientific research, such as radioactive waste TBP+ diluent produced in the hydrometallurgy process of uranium, lubricating oil in the primary circuit system of nuclear power plants, vacuum pump oil, etc. The aqueous reprocessing of spent fuel will produce TBP+ diluent organic waste liquid with high radioactivity. At present, there are many treatment methods for radioactive organic waste: incineration, acid digestion, wet oxidation, electrochemical oxidation and other methods; among them, incineration is widely used in organic waste treatment because of its high volume reduction ratio. However, the inc...
