Abstract

PURPOSE: To miniaturize the above-mentioned treating apparatus and to fed smoothly the thawed sludge to the dehydration apparatus at that, by uniting the freezing tank for freezing the sludge such as foul mud, etc., the thawing tank for heating and thawing the frozone slurry generated in the above tank and the dehydrating apparatus for dehydrating the thawed sludge and for forming the cake to one body.
CONSTITUTION: The sludge 21 such as foul mud, etc. is pressed into the freezing tank 1 and, at this time, the frozen sludge 22 which has been frozen previously, has been pushed out in the thawing tank 2 at the lower part 5. Then, by passing the refrigerant into the passage 3 for refrigerant, the sludge in the tank 1 is frozen. Subsequently, by making the heat medium flow temporarilly in the passage 3, only the surface of the frozen sludge 22 thaws and is made to be above to move. Further, the thawed sludge 23 in the tank 2 is transferred onto the filter belt 31 by opening the shutter 35 the moisture in the above sludge 23 is separated by filtering by making the pressure inside the vacuum tank 32 negative, the belt 31 is lowered to the prescribed position together with the tank 32 as expressed with the one-point chain line and, in this way, the cake is discharged to the outside.
