Abstract

PURPOSE: To effectively digest sludge at low running cost by a method in which digestion gas generated in a digestion tank is heated and then returned to the sludge- digesting section of the digestion tank.
CONSTITUTION: Sludge, e.g., sewage sludge, etc., is sent to the lower part of the sludge-digesting section of a digestion tank 1. Portion of digestion gas generated from the top is sent to a pressure riser 12 and then sent to a heater 13 where it is heated up to a necessary temperature by high-temperature waste gas or water, etc., discharged from factory. The larger portion of the digestion gas so heated is sent to the lower part of the sludge-digesting section 2 to heat and stir the sludge. Portion of the digestion gas heated is sent through the pressure booster 17 to the bottom of a collecting and concentrating section 3 in the digestion tank 1, where it carrys out the heating and slight agitation of the bottom section. By this method, the efficiency of digestion can be raised by a simplified structure.
