Abstract
The invention relates to a method and a device for anaerobic digestion from an organic liquid sludge (), comprising, in a known manner, a step of hydrolysis/acidogenesis of the sludge in a digester (), a step of acetogenesis for producing acetate from the hydrolysed sludge and a step of methanogenesis from the acetates for producing methane. The method comprises an initial step of creating a hydrolysed sludge emulsion () obtained by means of the impact of the sludge with gas () injected into the sludge, then continuously supplying the hydrolysed sludge to a reactor () pressurised in line relative to the digester, before discharging said sludge from the reactor via a member () generating a pressure drop in the hydrolysed sludge, the initial stage being repeated at least once before supplying the, and/or via the, digester.
