Abstract

PURPOSE: To prevent the diffusion of turbid as well as discard sludge by uniformly spreading it by a method in which solidified sludge is discharged on the seabed through a floating cylinder having a rectifying plate inside, and then a flocculant is added to the sludge.
CONSTITUTION: When discharging solidified sludge from a hopper 1, it slowly settles along the rectifying plate 3 of a cylinder 2. When turbid occurs greatly in the cylinder 2 as the sludge is discarded, an anionic high molecular flocculant is added to the sludge in the cylinder 2 in such a way as to flocculate and settle the sludge for suppressing the occurrence of turbid.
