Abstract

PURPOSE: To prevent the wear and damages of a sludge disposal facility, by beforehand removing coarse matters and sand by disposing sludge formed at a sedimentation basin in a city sewage disposal plant by means of a screen device and a liquid cyclone.
CONSTITUTION: Sludge formed at a first sedimentation basin 2 and a final sedimentation basin 4 is introduced to a screen device 9, thus removing screen residue. Heavy sand is removed by introducing said sludge to a liquid cyclone 11 through a storage tank 10, and the disposed sludge is successively disposed in such a manner that it is introduced to a concentration tank 5, a digestion tank 6, a dehydration device 7 and an incinerator 8. Since the digestion of sludge becomes active in the digestion tank by removing sand in sludge, the formation of scum can be prevented.
