。The gas-liquid mixing reaction tank (22)C shown in FIG.
2) When air is injected upward from the diffuser pipe (2)C at the bottom of C, air bubbles rise inside the inner cylinder (12)C, and the air lift effect causes the liquid in the tank (22)C to move as shown by the arrow. However, in order to increase the circulation amount of the liquid, it is necessary to increase the amount of air jetted from the diffuser pipe (2)C. However, as the amount of air injected from the aeration tube (2)C increases, bubbles will often merge with each other (bubble inclusion), and the amount of liquid circulating in the tank (22)C will decrease. ) It does not increase in proportion to the increase in the amount of air jetted from C, and there is a limit to the amount of circulation of the liquid. Therefore, in the gas-liquid mixing reaction tank (22)C shown in FIG. 4, the liquid flow energy is insufficient and uneven flow occurs, and the fixed bed (13)D
Clogging is likely to occur within the tank (22), the efficiency of dissolving air in the fluid is poor, and sludge S is likely to be deposited at the bottom of the tank (22)C. On the other hand, in the gas-liquid mixing reaction tank (22)E shown in Fig. 5, the flow resistance of the fixed bed (13)F is not uniform, so the circulation of the liquid becomes irregular and uneven flow occurs, and the power for air injection is The tank (22) E sludge S is likely to be deposited.

Also, the position where the water to be treated comes into contact with the inner wall of the gas-liquid mixing cylinder (3) is set to be approximately in the middle of the gas-liquid mixing cylinder (3), making it easy to suction a large amount of the water to be treated. At the same time, the liquid-air mixture flows within the gas-liquid mixing cylinder (3) without being subjected to large flow resistance. Furthermore, if the length Q of the gas-liquid mixing cylinder (3) is more than twice the diameter D2 of the gas-liquid mixing cylinder (3), the gas introduced from the gas blowing pipe (7) in the liquid-air mixture It is thoroughly mixed with the water to be treated.
