PROBLEM TO BE SOLVED: To apply the oscillation suitable for preventing filtering holes from being clogged to a filtering cylinder by a simple structure in a screw press dewatering apparatus comprising the filtering cylinder having a large number of filtering holes, a screw provided in the filtering cylinder, and a driving unit to rotate the screw, and applying the compression force to a slurry present between the screw and the filtering cylinder from the upstream side to the downstream side of the screw. SOLUTION: This screw press dewatering apparatus has an exciting device 6 for preventing the filtering holes 2 from being clogged by oscillating the filtering cylinder 3 by applying the blow to the filtering cylinder 3. In addition, the blow, the blowing position and the blowing period are adjustable independently.
