Abstract
La présente invention concerne une électrode pour réduire la demande chimique en oxygène d'eaux usées qui comprend : a) un composant permanent; et b) un composant sacrificiel disposé face à face avec le composant permanent et fixé amovible et en contact électrique avec celui-ci, ledit composant permanent étant constitué d'un substrat d'un métal valve pourvu d'un revêtement catalytique contenant des métaux nobles ou des oxydes associés, ledit composant sacrificiel contenant du fer élémentaire. L'invention concerne également un procédé de réduction de la demande chimique en oxygène dans un résidu aqueux contenant des composés huileux, des glycols ou des paraffines, comprenant facultativement un résidu de fonderie, par un procédé électrolytique impliquant le dégagement de chlore à l'anode en présence de fer trivalent. Le dégagement de chlore peut s'effectuer à la surface d'une anode composée d'un composant permanent à métal valve activé catalytiquement couplé à un composant sacrificiel contenant du fer.
