Abstract

A method for efficiently thickening and dewater-ing a slurry sludge in a short period of time without the necessity of a vast site, which comprises the steps of:
stirring a slurry sludge added with a coagulant in a stirring tank to convert the slurry sludge into a floc;
supplying the floc and a supernatant liquid, which are produced in the stirring tank, onto an inlet side of an inclined endless travelling filter cloth of an endless travelling filter cloth type dewatering unit, which comprises a dewatering tank and the above-mentioned inclined endless travelling filter cloth arranged in the dewatering tank; continuously travelling the thus supplied floc, on the endless travelling filter cloth, toward an exit side thereof; thickening the floc on a portion of the endless travelling filter cloth, which portion is located in the supernatant liquid in the dewatering tank, and dewatering the thus thickened floc on a portion of the endless travelling filter cloth, which portion is located above the surface of the supernatant liquid in the dewatering tank.
