Abstract

PURPOSE: To absorb water content of sludge, to remove offensive odor and to enable easy handling, by pulverizing the sludge and coating the surface with a dehydrating coating material.
CONSTITUTION: Sludge generated from sewage, excretions or the like such as night soil, excretions of stocks or filthy water in the disposal of sewage, etc. is carried from a sludge chamber 2 to a screw conveyer 6, where the sludge is agitated with blades 8 and concurrently cut to short pieces at their back ends. The cut sludge is then carried through a passage 12 into the next screw conveyer 13. At this time, a water-absorbing coating material powder such as zeolite powder, lime powder, wood powder, chaffs, etc. in a reservoir 15 is charged into the sludge through a discharge opening 21 at a ratio of 20W25%. In the screw conveyer 13, the sludge is divided into fine pieces with rods 26 attached to a rotary shaft 24, and the coating material is applied onto the entire surface of the divided sludge to absorb water content from the sludge. Consequently, the sludge is changed to a granular state containing less water, deodrized and made easily handleable at once.
