Title
(EN) BIOELECTROCHEMICAL METHOD AND APPARATUS FOR ENERGY RECLAMATION FROM NITROGEN COMPOUNDS
(FR) PROCÉDÉ BIOÉLECTROCHIMIQUE ET APPAREIL DE RÉCUPÉRATION D'ÉNERGIE À PARTIR DE COMPOSÉS AZOTÉS
Abstract
(EN)
Methods are described for treating aqueous solutions, including wastewater, to remove nitrogen-containing compounds using electrochemical processes. The method may be conducted electrolytically under an applied voltage or using endogenous current in a fuel cell arrangement. In some embodiments, energy is reclaimed in the form of hydrogen, methane, and other hydrocarbons or organic molecules. Microorganisms may be used as the catalyst for oxidation of the nitrogen-containing compound and/or reduction of hydrogen ions, carbon dioxide, or bicarbonate. Anaerobic or low-oxygen conditions may be used in the zone.
(FR)
L'invention concerne des procédés pour traiter des solutions aqueuses, y compris des eaux usées, en vue d'éliminer des composés contenant de l'azote à l'aide de procédés électrochimiques. Le procédé peut être mis en œuvre par électrolyse sous une tension appliquée ou à l'aide d'un courant endogène dans un système de pile à combustible. Dans certains modes de réalisation, l'énergie est récupérée sous la forme d'hydrogène, de méthane et d'autres hydrocarbures ou molécules organiques. Des microorganismes peuvent être utilisés comme catalyseur pour l'oxydation du composé contenant de l'azote ou la réduction des ions hydrogène, du dioxyde de carbone ou du bicarbonate. Des conditions anaérobies ou à faible teneur en oxygène peuvent être appliquées dans la zone.
