Abstract

PURPOSE: To even the thickness of floating sludge and improve the recovery efficiency of concentrated sludge by a scraper which moves horizontally and a treating water tank gate plate which opens and closes in compliance with the signal from a sludge concentration detector.
CONSTITUTION: The waste water containing sludge is flowed through inlet pipe 1 into a floating concentrating tank 8 and is allowed to float by mixing pipes 4, 6. In order to scrape out the sludge zone 31, a truck 12 is moved horizontally on rails through winding of wire ropes. When it goes toward the discharge port, it lowers a scraper 13 on the liquid surface and when it advances in the opposite direction, it raises the scraper. As a result, a gate plate 25 is opened and closed in compliance with the signal by a sludge concentration detector 16 and the sludge of always a fixed concentration may be discharged.
