Abstract

Abstract Apparatus for sewage purifying treatment having a suction nozzle member for supplying pressurized water, an intermediate nozzle member and an injection nozzle member, each having a water passage therein, each nozzle being connected to each other. An air introducing nozzle is formed between nozzle members. An outer casing is arranged in such a fashion that an air introducing chamber is formed at the outer circumference of the intermediate nozzle member, the air introducing chamber and the air introducing nozzle communicating with each other. A pressurized water supply pipe is connected to an end of the suction nozzle member and an air supply pipe is connected to the outer casing for supplying the air to the outer casing. A groove for micronizing coarse bubbles are formed at the downstream position of the air introducing nozzles.
