ABSTRACT:
In order to treat an aqueous acid effluent resulting from the decontamination of a component of a nuclear power station, the effluent containing an organic load comprising an organic reducing agent and nitrate ions and at least one oxidizing compound is introduced into the effluent. The effluent is then subjected to ultraviolet radiation and the totality of the organic load is thus converted into water and carbon dioxide, as well as possibly into at least one oxide of a chemical element present in the organic load, while neutralizing the effluent.
