Process for digesting sludge by oxygenation in a first closed zone, at a temperature of 45 to 75 DEG C, and then subjecting the partially stabilised sludge originating from these zones to an anaerobic digestion in a second closed zone, at a temperature of 30 to 60 DEG C. This process can be applied to the removal of waste water. <IMAGE> |
