Abstract

Procédé d'élimination d'une proportion substantielle des substances volatiles organiques et/ou minérales d'un courant gazeux odorant, caractérisé en ce qu'on fait passer ledit courant gazeux dans au moins un épurateur de gaz comprenant une suspension aqueuse de matières solides biologiques à une concentration comprise entre environ 50 mg/l et 20 000 mg/l et du charbon activé à une concentration comprise entre environ 50 mg/l et 20 000 mg/l. Application aux divers traitements de courants gazeux odorants formés dans des processus industriels, en particulier dans le traitement des boues ou le traitement des eaux usées.Process for removing a substantial proportion of volatile organic and / or mineral substances from an odorous gas stream, characterized in that said gas stream is passed through at least one gas scrubber comprising an aqueous suspension of biological solids at a concentration between approximately 50 mg / l and 20,000 mg / l and activated charcoal at a concentration between approximately 50 mg / l and 20,000 mg / l. Application to the various treatments of odorous gas streams formed in industrial processes, in particular in the treatment of sludge or the treatment of waste water.
