Abstract

PURPOSE:To discharge scum efficiently by providing a floating lid retained on the surface of a liq. in a sedimentation tank and an endless chain passage along the bottom surface of the sedimentation tank. CONSTITUTION:Upon sewage entry into an untreated liq. tank 7, the sewage is passed through holes 6 into a flow distributed state and then supplied into a sedimentation tank 2. A sedimentary sludge is settled on a bottom surface 2a and scraped by scrape plates 11 of a moving scraper 3 into a sludge pit 2a'. The sludge settled on the sludge pit 2a' is sent through a sludge discharge pipe 19 into a sludge treating device for treatment thereof. A floating scum is moved up to the liq. surface and reaches the inner surface of a floating lid 5. The scum thus formed on the inner surface of the floating lid 5 is carried toward a skimmer by a moving return part (b) of the scraper 3 and entered into a pipe 4a for discharge from the sedimentation tank 2. By this device, the emission of a bad odor is prevented.
