Abstract

PURPOSE: To reduce the consumption of power as well as compact apparatus by using a sludge freezing tank of a three-layered structure consisting of a sludge-charging layer, a cooling medium layer, and a sludge-partly thawing layer.
CONSTITUTION: The sludge in the sludge layer 22 is frozen by the refrigerator in the cooling medium layer 20, and then part of the frozen sludge, or only its contact portion with the hot-thawing layer 21, is thawed by the heating medium of the hot- thawing layer 21. Then, the delivery valve 10 is opened to drop the frozen sludge onto the belt conveyer 12, the dropped frozen sludge is carried to the sludge thawing tank 23 by the belt conveyer 12, and the thawed sludge is dehydrated by the dehydrator 11 and discharged by the conveyer 12. Thus, the consumption of power can be more greatly reduced and also the number of dehydrating apparatus can be more lessened than the conventional apparatus.
