が水タンク２に流入する。In FIG. 1, kitchen waste crushed by a disposer 1 flows into a water tank 2. The water tank 2 is made by a pressurized water tank N3, and water in which air is dissolved flows into the water tank 2 after being foamed under reduced pressure. Microbubbles due to foaming adhere to the crushed kitchen waste, and the kitchen waste with buoyancy is separated into a floating scum layer 5. Here, the kitchen waste is oxidized and decomposed by microorganisms to reduce its weight. At this time, the 1ffr organism consumes a large amount of oxygen, or this oxygen is supplied by the -I air bubbles. The water from which the crushed kitchen waste has been removed flows into the water treatment device 6. Microorganisms attached to the fixed bed 7 of the water treatment device 6 decompose organic contaminants dissolved in the water. The purified water is then discharged from the water pipe 9. The oxygen consumed by microorganisms in this process is supplied by water in which air has been dissolved to a saturation concentration even after foaming. Also,
Some of the water passes through the water pipe 8 and returns to the pressurized water production device 3.
It is the raw material for pressurized water. Air, which is a raw material for pressurized water, is supplied from an air pipe (not shown). 3 In this way, the water tank 2, the water treatment device 6, and the pressurized water production device 3 are connected to a loop, and crushed kitchen waste flows into the water tank 2 from the disposer.

5. Supplied by water pump 14. Air, which is a raw material for pressurized water, is supplied from the atmosphere by an air pipe 13 and an air pump 12. Pressure for producing pressurized water is applied by the water supply pump 14 and the air pump 12.
加圧タンク１０の内部において、気液接触により得られ
た加圧水は減圧弁１６により減圧されて発泡し、加圧水
配管１７により水タンク２に流入する。Inside the pressurized tank 10, the pressurized water obtained by gas-liquid contact is depressurized by the pressure reducing valve 16, foams, and flows into the water tank 2 through the pressurized water pipe 17.

型加することができる。The draft tube 11 faces directly above the air pipe 13, and the air pipe 13 is connected to the bottom surface of the pressurized tank 10 and is open. Due to this draft tube 11, air entrains water and rises inside the draft tube 11.
Since convective movement of water in the pressurized tank 10 is promoted and gas exchange on the water surface is accelerated, the residence time of water in the pressurized tank can be shortened. This allows the pressurized water tank to be made smaller.

圧タンク１０を更に小型化することができる。The valve 18 of the check valve 20 suspends one float,
When the water level of the pressurized water in the pressurized tank 10 drops, the check valve 20 is opened. As a result, the gas phase air in the pressurized tank 10 passes through the check valve 20 and the bypass pipe 2, returns to the air pipe 13 between the air pump 2 and the check valve 22, passes through the air pump 12, and is pressurized. A circulating air path returning to the tank 10 is formed. Then, the gas phase air is discharged from directly below the raft duplex 11 and rises inside the draft tube 11, drawing in water. This operation promotes the convection of water within the pressurized tank 10, increases the number of times water and air come into contact, and further increases the dissolution rate of air, so that the pressurized tank 10 can be further downsized.

空気の比率をコントロールすることができる。While this circulating air path is open, the supply of air from the atmosphere is stopped, so the water level in the pressurized tank 10 rises due to the supply of water by the water pump 14. When the backflow prevention valve 20 is closed by the buoyancy of the float 19 due to the rise in the water surface, the circulation air path is also closed and the supply of air from the atmosphere starts again. In this way, the water level in the pressurized tank 10 is kept almost constant, raw air is supplied in just the right amount, and the ratio of water and air can be controlled.
