Abstract

PURPOSE: To purify polluted water by performing concurrently both activated sludge treatment and denitrification treatment by providing a denitrification chamber having holes on its outside surface in a slow and inactive oxidation zone at the central part of aeration tank.
CONSTITUTION: When a polluted water, e.g., urban sewage, night soil, etc., is introduced from the inflow pipe 12 into the aeration tank 11 and then air is blown into the tank by the air diffuser 15, the polluted water makes a spiral movement along the inside wall surface of the aeration tank 11 and meets with activated sludge to undergo denitrification treatment. And the spirally flowing polluted water and part of activated sludge enter through the water path opening 17 in the outside wall surface of the denitrification chamber 16 into the denitrification chamber 16 by means of the flowing water energy to undergo denitrification treatment by denitrifying bacteria. Thus, polluted water can be purified by performing concurrently both activated sludge treatment using a vigorous spiral flow and denitrification treatment using a super slow flow in the same tank.
