Abstract

LA PRESENTE INVENTION CONCERNE UN PROCEDE DE TRAITEMENT ELECTROCHIMIQUE D'UNE COMPOSITION AQUEUSE COMPRENANT UNE OU PLUSIEURS SUBSTANCES ORGANIQUES, AU MOYEN D'UN REACTEUR ELECTROCHIMIQUE COMPORTANT UN COMPARTIMENT ANODIQUE ET UN COMPARTIMENT CATHODIQUE, LESDITS COMPARTIEMENTS ETANT SEPARES PAR UN SEPARATEURAPPROPRIE, CARACTERISE EN CE QU'ON INTRODUIT LADITE COMPOSITION AQUEUSE DANS LE COMPARTIMENT ANODIQUE DU REACTEUR ELECTROCHIMIQUE, LEDIT COMPARTIMENT ANODIQUE CONTENANT UN SUPPORT LIQUIDE DANS LEQUEL SONT PRESENTES EN SUSPENSION DES PARTICULES ACTIVES ELECTROCHIMIQUEMENT ET EN CE QUE SIMULTANEMENT OU SUCCESSIVEMENT ON SOUMET LE MILIEU RESULTANT DE L'INTRODUCTION DE LADITE COMPOSITION AQEUSE, A UN POTENTIEL D'OXYDATION ET A L'ACTION D'ULTRASONS. ELLE CONCERNE EGALEMENT UN DISPOSOTIF ELECTROCHIMIQUE, NOTAMMENT POUR METTRE EN OEUVRE LEDIT PROCEDETHE 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 CATHODE COMPARTMENT, SUCH COMPARTMENTS AS A SEPARATOR. THE SAME AQUEOUS COMPOSITION IS INTRODUCED INTO THE ANODIC COMPARTMENT OF THE ELECTROCHEMICAL REACTOR, SAID ANODIC COMPARTMENT CONTAINING A LIQUID MEDIUM IN WHICH THEY ARE PRESENT SUSPENDED ELECTROCHEMICALLY ACTIVE PARTICLES AND WHEN SIMULTANEOUSLY CONTINUED TO RESULT , TO A POTENTIAL OF OXIDATION AND TO THE ACTION OF ULTRASOUND. IT ALSO CONCERNS AN ELECTROCHEMICAL DEVICE, PARTICULARLY FOR IMPLEMENTING SAID PROCESS
