Abstract

Selon un procédé d'épuration de liquides contaminés, le liquide contaminé, par exemple de l'eau, s'écoule à travers une chambre de dispersion située entre deux électrodes et remplie d'un matériau granulé conducteur de l'écoulement. Un réacteur électrochimique d'épuration de liquides contaminés comprend un récipient pourvu de tubulures d'amenée et d'évacuation de liquides, par exemple de l'eau, et deux électrodes cylindriques coaxiales à diamètres différents situées dans le récipient. La chambre de dispersion située entre les électrodes est remplie d'un granulé approprié conducteur de l'écoulement par contact de surface.
