The present invention relates to a method and a plant for the wet-route oxidation treatment of hazardous organic waste, notably radioactive waste, that may contain mineral fillers, this waste being treated in a confined manner in a secure environment. The plant essentially comprises a closed chamber (11), means for conveying a volume of said organic waste in a contained manner, equipment for adding to said predetermined volume a given quantity of water mixed with a base so as to adjust the pH to a determined value, a pressure reactor (20) and means for transferring said solution and/or said liquid suspension into said pressure reactor (20), a device for introducing an atmosphere of oxygen into said pressure reactor (20) and for placing said atmosphere under a maximum pressure of 80 bar. Heating equipment is provided in order to subject said pressure reactor (20) and its contents to a heat treatment at a temperature substantially comprised between 150 and 350°C in order to finalize said wet-route oxidation under subcritical conditions, water being kept in the liquid state. |
