AERATION METHOD AND DEVICE THEREFOR

摘要

PURPOSE:To generate an intratank circulating flow even in a deep tank of 10m or over and carry out agitation of and aeration to a soil water uniformly in whole the inside of the tank. CONSTITUTION:A pressurizing chamber 2 is provided in a state of floating or fixed state at a prescribed depth in an aeration tank 1 of desired thickness. High pressure air of preset air pressure or oxygen is fed to the pressurizing chamber 2. A self-suction aeration machine 3 set in the pressurizing chamber 2 is operated to suck the air or oxygen in the pressurizing chamber 2 and the air or oxygen is exhausted to water at the tank bottom section or at the vicinity of the tank bottom section. The air or oxygen is agitated together with the water to carry out uniform agitation and aeration in the deep tank.
