Abstract

Procédé d’oxydation de composés organiques contenus dans un milieu liquide anoxique, comprenant une surface supérieure au-dessus de laquelle se trouve un milieu gazeux contenant un composé oxydant, accepteur d’électrons, dans lequel on réalise les étapes successives suivantes : a) Mise en contact du milieu liquide anoxique, avec un support poreux tridimensionnel, dans lequel : le support comprend une première partie, dite partie émergée, qui se trouve au-dessus de la surface supérieure du milieu liquide, en contact avec le milieu gazeux, et une seconde partie, dite partie immergée, qui se trouve au-dessous de la surface du milieu liquide ; le volume de la partie émergée représente au moins 20% du volume total du support; au moins 80%, de préférence au moins 90%, et de préférence encore la totalité (100%) de la surface interne des pores et de la surface externe du support poreux est recouverte par un biofilm qui ne colmate pas les pores ; b) Remontée par capillarité, dans les pores du support poreux, du milieu liquide contenant les composés organiques depuis la partie immergée vers la partie émergée du support; c) Mise en contact des composés organiques dans la partie émergée du support avec le composé oxydant, accepteur d’électrons et oxydation des composés organiques par le composé oxydant, accepteur d’électrons catalysée par le biofilm. Figure pour l’abrégé : Figure 3.Process for the oxidation of organic compounds contained in an anoxic liquid medium, comprising an upper surface above which is a gaseous medium containing an oxidizing compound, an electron acceptor, in which the following successive steps are carried out: a) Putting in contact with the anoxic liquid medium, with a three-dimensional porous support, in which: the support comprises a first part, called the emerged part, which is located above the upper surface of the liquid medium, in contact with the gaseous medium, and a second part, called the submerged part, which is located below the surface of the liquid medium; the volume of the emerged part represents at least 20% of the total volume of the support; at least 80%, preferably at least 90%, and more preferably the entirety (100%) of the internal surface of the pores and the external surface of the porous support is covered by a biofilm which does not clog the pores; b) Rising by capillarity, in the pores of the porous support, of the liquid medium containing the organic compounds from the submerged part towards the emerged part of the support; c) Bringing the organic compounds into contact in the emerged part of the support with the oxidizing compound, electron acceptor and oxidation of the organic compounds by the oxidizing compound, electron acceptor catalyzed by the biofilm.
