Abstract

LA PRÉSENTE INVENTION CONCERNE UN PROCÉDÉ DE TRAITEMENT ÉLECTROCHIMIQUE D'UNE COMPOSITION AQUEUSE COMPRENANT UNE OU PLUSIEURS SUBSTANCES ORGANIQUES, AU MOYEN D'UN RÉACTEUR ÉLECTROCHIMIQUE COMPORTANT UN COMPARTIMENT ANODIQUE ET UN COMPARTIMENT CATHODIQUE, LESDITS COMPARTIEMENTS ÉTANT SÉPARÉS PAR UN SÉPARATEUR APPROPRIÉ, CARACTÉRISÉ EN CE QU'ON INTRODUIT LADITE COMPOSITION AQEUSE DANS LE COMPARTIMENT ANODIQUE DU RÉACTEUR ÉLECTROCHIMIQUE, LEDIT COMPARTIMENT ANODIQUE CONTENANT UN SUPPORT LIQUIDE DANS LEQUEL SONT PRÉSENTES EN SUSPENSION DES PARTICULES ACTIVES ÉLECTRONIQUEMENT ET EN CE QUE SIMULTANÉMÉNT OU SECCESSIVEMENT ON SOUMET LE MILIEU RÉSULTANT DE L'INTRODUTION DE LADITE COMPOSITION AQUEUSE, À UN POTENTIEL D'OXYDATION ET À L'ACTION D'ULTRASONS. ELLE CONCERNE ÉGALEMENT UN DISPOSITIF ÉLECTROCHIMIQUE , NOTAMMENT POUR METTRE EN OEUVRE LEDIT PROCÉDÉ.THE PRESENT INVENTION RELATES TO A PROCESS FOR THE ELECTROCHEMICAL TREATMENT OF AN AQUEOUS COMPOSITION COMPRISING ONE OR MORE ORGANIC SUBSTANCES, BY MEANS OF AN ELECTROCHEMICAL REACTOR COMPRISING AN ANODIC COMPARTMENT AND A CATHODIC COMPARTMENT, WHICH ARE SEPARATED AS A PARTIAL PARTS OF PARTS. THE SAME AQUOUS COMPOSITION IS INTRODUCED INTO THE ANODIC COMPARTMENT OF THE ELECTROCHEMICAL REACTOR, SAID ANODIC COMPARTMENT CONTAINING A LIQUID MEDIUM IN WHICH THEY ARE PRESENT IN SUSPENSION OF THE ACTIVE PARTICLES ELECTRONICALLY AND AS A SIMULTANEOUSLY CONDUCTED OR CONTINUALLY CONTAINED. AQUEOUS, WITH A POTENTIAL OF OXIDATION AND THE ACTION OF ULTRASOUND. IT ALSO RELATES TO AN ELECTROCHEMICAL DEVICE, PARTICULARLY FOR CARRYING OUT SAID PROCESS.
