Abstract

PURPOSE: To effectively perform the complete fermentation treatment of sludge by dividing and arbitrarily combining storage tank, fermentation tank, lower fermentation tank, and carry-out fermenting treatment according to the property and maturity of the sludge to be treated.
CONSTITUTION: A substance to be treated by fermentation, e.g., sludge, is put in a raw storage tank A, where it is stirred by rotation of a stirring blade 2 and flowed from the cutback floor 3 at the bottom into a fermentation tank B or directly a hopperlike lower fermentation tank C for fermentation treatment. In this case, these tanks A, B, and C are combined in the manner of A-B-C-D, A-A-C-D, A-A-B-C-D, etc., according to the property and muturity of sludge to be treated. The substance treated by fermentation is carried out by a carry-out means 7, e.g., screw conveyer, etc., jointed to the lower part of the lower fermentation tank 7. By this method, a continuous fermentating treatment can be performed without the needs for such pretreatments as mixing, granulation, storage, etc.
