Abstract
The invention concerns a method for purifying aqueous effluents, in particular polluted water, by catalytic oxidation using a three-phase reactor comprising two communicating chambers. The invention is characterised in that it consists in: maintaining the catalyst suspended and continuously circulating it between the two chambers of said reactor, by entrainment under the effect of carrier gas injected into one of said chamber, and in oxidizing the pollutants in contact with the in the other chamber, by injecting a reactive oxidizing gas in said other chamber.
