摘要
1. Device for the anaerobic fermentation of manure with a view to the production of bio-methane, this device being characterized in that it comprises a reactor, into the bottom part of which is introduced the manure in a reactional aqueous medium, this manure progressing during fermentation towards the top part of the reactor where the drawing off of the gas produced, separated from the solids is carried out, in that this reactor comprises a perforated vertical partition separating it internally into two compartments, the first receiving the manure and the second, at least in part, occupied by a porous packing of fixation of the microorganisms, ensuring the fermentation, and in that a recycling decanter is associated to the reactor, this decanter being fed from the second compartment of the reactor by the liquid fraction evacuated from the reactor that it separates into one part enriched in recycled microorganisms towards the second compartment, and a second impoverished part that is rejected.
