Abstract

L’invention concerne un procédé de traitement thermique de résidus de combustion (en particulier, de cendres de filtre) provenant d’installations de combustion d’ordures ménagères (10). Le procédé comprend les étapes suivantes : - chauffage des résidus de combustion pour faire passer les constituants toxiques des résidus de combustion en phase gazeuse; - extraction par filtration des métaux lourds à partir de la phase gazeuse; - séparation par filtration du mercure à partir de la phase gazeuse; - passage des gaz résiduels contenant des dioxines et des furannes, dans une installation de combustion des déchets (10) et mise à la décharge des résidus de combustion traités. Des modes de réalisation avantageux du procédé prévoient un autre traitement des résidus de combustion, de sorte que finalement, une mise à la décharge ultérieure des résidus de combustion traités est possible, car ils ne contiennent plus d’éléments toxiques (dioxines, furannes, oxydes de mercure et/ou métalliques).
