備が必要であり好ましくない。In the treatment of water with ozone, since the solubility of ozone in water is small, it is important to increase the contact between ozone and water to improve the treatment efficiency. For this purpose, a diffuser tube made of a porous material such as ceramics is placed at the bottom of the reaction tank for ozone to bring bubbles of ozone-containing gas into contact with water, or the ozone-containing gas is submerged in water through the inner tube of the double tube. A U-tube type contact tank that raises the outer tube after introducing a gas-liquid mixed phase flow in which the gas is mixed into the bottom of the processing tank, and an ozone reaction tank using an ejector and a stirring tank are used. However, the one using an ejector or a stirring tank is not high in efficiency, and therefore a large number of ejectors, stirring devices, or large-scale equipment is required to treat a large amount of water, which is not preferable.

Generally, in a reaction tank having a water depth of about 6 m. , Requires a large footprint. On the other hand, in the U-tube type ozone reaction ellipse, the pressure rises when the water containing the bubbles of ozone-containing gas descends, and the dissolution rate of ozone increases as compared with the diffuser tube, but it requires a water depth of 20 to 100 m. , Requires a special reaction tank.
