Abstract

Procédé de récupération du fer de boues de station d'épuration d'eaux usées obtenues après précipitation par des sels de fer, caractérisé en ce qu'il comprend une étape unique de re-dissolution du fer desdites boues par voie biologique, suivie d'une étape de séparation du fer de la fraction liquide obtenue à l'issue de l'étape biologique de dissolution du fer. L'étape biologique comprend une étape unique de fermentation desdites boues en présence de substrats riches en carbone facilement biodégradable, à une teneur supérieure ou égale à 0,3 g de DCO/ MV, conduisant à la libération du fer desdites boues et à sa mise en solution. Utilisation du procédé pour le recyclage d'au moins une partie des sels de fer, tel que ceux employés dans les stations d'épuration d'eaux usées, par exemple mettant en œuvre une étape de précipitation par le chlorure ferrique.
