Abstract
Method of treating an aqueous effluent containing organic matters in solution, comprising the following successive steps: the effluent is rendered basic; the effluent rendered basic is mineralized by being brought into contact with a gaseous oxidizing agent; the mineralized basic effluent is rendered acidic; and the effluent rendered acidic is again mineralized by being brought into contact with the gaseous oxidizing agent.
Claims16
Method of treating an aqueous effluent containing organic matters in solution, comprising the following successive steps:
- the effluent is rendered basic;
- the effluent rendered basic is mineralized by being brought into contact with a gaseous oxidizing agent;
- the mineralized basic effluent is rendered acidic;
- and
- the effluent rendered acidic is again mineralized by being brought into contact with the gaseous oxidizing agent.
Method according to any one of the preceding claims, in which the mineralization steps are carried out at a temperature of 5 to 70° C., preferably of 20 to 30° C.
Method according to any one of the preceding claims, in which the organic matters are surface-active agents or surfactants, and/or complexing agents or chelating agents.
Method according to any one of the preceding claims, in which the effluent to be treated is an acidic effluent.
Method according to any one of the preceding claims, in which the effluent to be treated is a radioactive effluent.
