摘要
The sewage treatment plant, with a biogas unit (20), has a digestion tower (11) for anaerobic stabilizing of the clarification sludge. The biogas unit has a fermenter for the biogas production, together with a heater machine and a generator to give the biogas outflow. Heat fallout from the heater is passed through a channel (13) to the digestion tower to support the anaerobic stabilizing. A gas channel (15) with a gas meter (15') leads from the digestion tower to the heater machine. A unit (11') has a heat supply channel (13") from the heater machine for thermal disintegration of the clarification sludge. The stabilized sludge is passed to a drying stage (18), with a heat supply (13') from the heater machine.
