Abstract

PURPOSE: To continuously return necessary quantity of activated sludge surely with very simple construction, by sending the activated sludge in separation apparatus to the activated sludge recovering vessel by nearly U-shaped syphon tube and moreover, returning to the activated sludge process treating apparatus.
CONSTITUTION: Air containing O2 is supplied to treating water in the vessel 3 of the activated sludge process treating apparatus 5 and improvement of corruption index of the quantity of biochemical oxygen demand etc. by the activated sludge, is carried out. Then, clean water dissolved the air, is mixed with the treating water and mixed water is sent to the separation vessel 11 and then, separation treatment is carried out under the condition of heightening the aggregation effect of the activated sludge by aeration foaming. The activated sludge in the vessel 11 is taken out and is returned to the apparatus 5 through the mechanism 9. The syphon tube 19 forming the reverse U-shaped duct a by the scraping apparatus 10 side and the wall 8a of the recovery vessel 8, is provided in the mechanism 9. Floating activated sludge scraped by the apparatus 10, is returned to the apparatus 5 through the duct a sucking up forcibly by the return apparatus 12.
