WASTEWATER PURIFYING APPARATUS AND AIR DIFFUSER

摘要

PROBLEM TO BE SOLVED: To efficiently perform pollution treatment in a grease trap by an air diffuser together using a minamigawa metamorphic rock being a catalyst means, a repulsive magnetic field from a permanent magnet and an air supply means.

SOLUTION: This wastewater purifying apparatus is equipped with a storage tank 4 for temporarily storing wastewater of every kind introduced from a wastewater introducing part 3, a septic tank 2 having a wastewater discharge part 5 and the air diffuser 11 arranged so as to be immersed in wastewater of every kind in the storage tank and discharging air bubbles into wastewater of every kind to stir the wastewater. The air diffuser of this wastewater purifying apparatus has a purifying material 41 housed in a purifying material housing chamber 31 and containing at least a granular or powdery minamigawa metamorphic rock, the permanent magnets arranged to a plurality of the walls of the purifying material housing chamber and arranged in opposed relationship through the purifying material to form a repulsive magnetic field and the air supply means connected to the outside of one wall of the purifying material housing chamber to supply air into the purifying material housing chamber. The penetration of wastewater of every kind into an air chamber 55 during the diffusion of air from an air diffusion pipe 56 and the purifying material housing chamber is excluded.
