DIFFUSER APPARATUS, AND DIFFUSER APPARATUS RUNNING METHOD

摘要

Provided is a diffuser apparatus which has fine pores capable of achieving a high oxygen migration efficiency and which is hardly clogged so that it can be stably run for a long term. The diffuser apparatus is characterized by comprising a diffusing plate (4) arranged in an aeration bath (12), for releasing pressurized air fed from a diffusing air feed pipe (3), as air bubbles from the fine pores of a diffusing face (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 diffusing plate (4).
