Abstract

PURPOSE: To enhance an oxygen dissolving efficiency and to supply an oxygen uniformly to the whole of bacteria, by dissolving an air in a pressurized water at a high concentration, feeding the air-dissolved water under a pressure to a disposal vessel, and releasing the water from the pressure in the disposal vessel to dissolve and mix the air into the solution in the disposal vessel.
CONSTITUTION: A part of a water to be disposed is carried under a pressure to a pressure tank 9 by a pressure pump 8 arranged below a biological disposal vessel 2. To the pressure tank 9 is charged a compressed air from a compressor 10 to dissolved an air into the water in the pressure tank 9 at a high concentration. This compressed water is carried toward the disposal vessel 2. Just before being introduced into the disposal vessel 2, the water is placed under a normal pressure for precipitation. Owing to this pressure release, the disposal vessel 2 is charged with the water containing a lot of air bubbles and saturated with dissolved air. Owing to the charge of the water saturated with the air, a sufficient amount of oxygen is fed to an organismcontaining waste water in the disposal vessel 2. Consequently, microbes are bred well in a filter bed, and the decomposition of organisms with aerobic bacteria is accelerated.
