Title (EN) LIQUID WASTE TREATMENT BIOREACTOR PROCESS AND APPARATUS
(FR) PROCEDE ET DISPOSITIF A BIOREACTEUR POUR TRAITEMENT DE DECHETS LIQUIDES
Abstract:
(EN) The present invention relates to a process and apparatus for biological treatment of liquid waste by an upflow aerobic biofilter and coating of the solid fraction by powder zeolite. The aerobic biofilter comprises a reactor filled with perforated media. The media prevent clogging by suspended material in the manure but allow accumulation of biomass within the reactor and high oxygen transfer.
(FR) L'invention concerne un procédé et un appareil pour traiter biologiquement des déchets liquides par un biofiltre aérobie à flux ascensionnel et pour recouvrir la fraction solide d'une couche de poudre de zéolite. Le biofiltre aérobie comprend un réacteur rempli d'élément perforés. Ces éléments empêchent le colmatage des matières en suspension dans le lisier mais autorisent l'accumulation de la biomasse à l'intérieur du réacteur ainsi qu'un transfert d'oxygène important.
