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.

Claims

1. An apparatus for sewage purifying treatment comprising:

a suction nozzle member for supplying pressurized water from its end portion, an intermediate nozzle member, an injection nozzle member, said nozzle members having a water passage within and being arranged on the same axial center, air introducing nozzles formed between nozzle members, an air introducing chamber formed at the outer circumferential part of said intermediate nozzle member, an outer casing, said air introducing chamber and said air introducing nozzles communicating with each other through the medium of an air introducing hole, a pressurized water supply pipe connecting to the end portion of said suction nozzle member and an air supply pipe for supplying the air to said air introducing chamber connected to said outer casing, and a far infrared radioactive substance layer formed at the inner surface of said air introducing chamber.
