Method of treating liquid effluents containing organic compounds
摘要:
The invention concerns a method of treating effluents in order to eliminate the organic compounds. The method comprises a primary oxidation stage with hydrogen peroxide in an alkaline medium, a secondary oxidation stage in a neutral medium and a subsequent absorption stage. The effluent thus treated can be discharged directly to drain. The invention can be applied in particular to effluents originating from photographic development baths.
