DIFFUSER APPARATUS, AND DIFFUSER APPARATUS RUNNING METHOD

摘要

The present invention provides a diffuser apparatus which has fine pores capable of achieving a high oxygen transfer efficiency and rarely becoming clogged so that the apparatus can be operated stably over a prolonged period. The diffuser apparatus according to the present invention includes: an aeration plate 4 that can be disposed in an aeration tank 12 in order to release pressurized air, fed from a diffusing air feed pipe 3, as air bubbles from fine pores formed in an aeration plate surface 4a; blow water feeding means 5 for feeding blow water into the diffusing air feed pipe 3; and an inserted pipe 7 for discharging the blow water, fed into the diffusing air feed pipe 3, from the aeration plate 4.
