Abstract

PURPOSE: To reduce the oxygen supply power and miniaturize an apparatus by connecting an ejector to a defoaming water nozzle provided above a liquid level of a reaction tank.
CONSTITUTION: A nozzle 5 communicated with an air supply flow passage 4 is provided within a reaction tank 2 and the treating water such as urban sewage, industrial waste water or the like is supplied to a reaction tank in an activated sludge containing condition and the treating water is purified while oxygen gas is supplied from a nozzle 5. In this case, a nozzle 6 is provided at an upper portion above a liquid level within a reaction tank 2 as well as a pump 7 is mounted and, moreover, an ejector 9 sucking air corresponding to supply the treating water for defoaming under pressure is mounted. Thereby, a gas supply amount by an apparatus 3 for supplying oxygen gas into a reaction tank 2 can be reduced and an apparatus with small power output can be used as well as miniaturized and is advantageous totaly from a standpoint of installation.
