CA 2254724

The invention concerns an optimised method for the treatment and energetic upgrading of urban and industrial sludge purifying plants. It consists of a "novel" combination of known and tested equipment, forming a compact assembly with six functions which are: anaerobic sludge digestion (1) and biogas production, mechanical dehydration (2) up to 22-24 % of dry matter, a gas turbine installation (3) burning the biogas into "total energy", thermal drying (4) of the sludge up to 92 % of dry matter consisting of a thin-layer drier and a vibrated drier/cooler with fluid bed (4b), condensation of the vapours (5) for heating the digester and the premises, and optimised energetic upgrading (6) of the dried sludge as booster fuel capable of being stored and fed into the refuse incinerating boiler-furnaces. The method is also applicable to the treatment and transformation of liquid manure into granulated and bagged fertiliser.

Procédé de traitement et valorisation énergétique optimisée des boues de stations d'épuration urbaine et industrielle. Il est constitué par une combinaison "nouvelle" d'équipements connus et éprouvés, formant un ensemble compact de six fonctions qui sont: une digestion anaérobie des boues (1) et production de biogaz, une déshydratation mécanique (2) jusqu'à 22-24 % MS, une installation de turbine à gaz (3) brûlant le biogaz en "énergie totale", un séchage thermique (4) des boues jusqu'à 92 % MS constitué d'un sécheur à couche mince et d'un sécheur/refroidisseur vibré à lit fluidisé (4b), une condensation des buées (5) permettant le chauffage du digesteur et des locaux et une valorisation énergétique optimisée (6) des boues séchées comme combustible d'appoint stockable et dosable dans les fours-chaudières d'incinération des ordures ménagères. Le procédé selon l'invention s'applique également au traitement et à la transformation en engrais granulé ensaché du lisier.
