Title (EN) AN ANAEROBIC DIGESTER AND A METHOD FOR TREATING SLUDGE IN THE DIGESTER
(FR) DIGESTEUR ANAÉROBIE ET PROCÉDÉ DE TRAITEMENT DE BOUES DANS LE DIGESTEUR
Abstract:
(EN) A method for treating sludge in an anaerobic digester includes the steps of providing a pit in the ground that is lined with a seal and then forming cells in the pit into which a mixture of vegetal waste and sludge that has optionally undergone a pre- acidification stage is provided. After a sealing cover is placed over the digester, an optional trigger is provided that enhances formation of biogas that is recovered from the digester to be utilized for the production of energy and the digested mixture recovered at the end of the use of the digester is utilized as an organic fertilizer.
(FR) La présente invention concerne un procédé pour traiter des boues dans un digesteur anaérobie, comprenant les étapes consistant à fournir un puits dans le sol qui est aligné avec un joint d'étanchéité et à former ensuite des cellules dans le puits à l'intérieur duquel est introduit un mélange de déchets végétaux et de boues qui a éventuellement subi une étape de pré-acidification. Après qu'un joint d'étanchéité a été placé sur le digesteur, un déclencheur éventuel est fourni pour améliorer la formation du biogaz qui est récupéré à partir du digesteur à utiliser pour la production d'énergie et le mélange digéré récupéré à la fin de l'utilisation du digesteur est utilisé comme fertilisant organique.
