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.
Claims15
A process for treatment of an acid aqueous effluent resulting from the decontamination of a component of a nuclear power station, said effluent containing an organic load comprising an organic reducing agent and nitrate ions, said process comprising the steps of
- (a) introducing into said effluent at least one oxidizing compound selected from a group consisting of ozone and hydrogen peroxide;
- (b) subjecting the effluent into which the oxidizing compound has been introduced to ultraviolet radiation;
- and
- (c) converting the totality of the organic load into water and into carbon dioxide, as well as possibly into at least one oxide of a chemical element present in the organic load, while neutralizing said effluent.
