Process and oxidation treatment facility of hazardous wet organic waste, including radioactive waste, which may contain mineral fillers.

摘要

The present invention relates to a method and an installation for the wet oxidation treatment of hazardous organic waste, especially radioactive, which may contain mineral fillers, these waste being treated in a confined manner in a secure environment. The installation essentially comprises a closed enclosure (11), means for conveying in confined form, a volume of said organic waste, equipment for adding to said predetermined volume a given quantity of water mixed with a base in order to adjust the pH at a predetermined value, a pressure reactor (20) and means for transferring into said pressure reactor (20) said solution and / or said liquid suspension, a device for introducing into said pressure reactor (20) an atmosphere of oxygen and to put said atmosphere under pressure. Heating equipment is provided for subjecting said pressure reactor (20) with its contents to a heat treatment at a temperature substantially between 150 and 400 ° C to finalize said wet oxidation.
