Is known to have bactericidal properties and does not harm the human body, and is used for treating drinking water, washing and sterilizing foods, bleaching and the like. However, ozone is
Since the solubility in water is small, it is important to efficiently mix ozone gas with water in order to stably produce a constant concentration of ozone water. As a device for producing ozone water to increase the contact area between ozone gas and water to improve the dissolution rate of ozone gas in water, a bubbling type that has a structure that injects bubbles of ozone gas into water has been used so far. And an ejector type using a Venturi tubular mixer (ejector) are known.

ることのできる方法についても知られていない。For example, in the case of a conventional ejector type ozone water producing apparatus having the structure shown in FIG. 2, ozone water is produced by dissolving ozone gas in the entire amount of water. Ejectors are usually designed based on a set maximum volume of water to be treated.
Therefore, when using such an ejector to treat a water amount less than the set maximum water amount, it becomes difficult to sufficiently mix ozone gas and water in the ejector, and as a result, the ozone injection pressure is increased. However, the ozone concentration in the obtained ozone water cannot be increased stably. Such problems also occur when the mixer is a bubbling type. As described above, it is difficult to stabilize the ozone concentration in ozone water over a wide range of water with the conventional ozone water manufacturing apparatus having only one flow path as shown in FIG. 2. No apparatus has been proposed that can efficiently produce ozone water by mixing ozone gas with water. Also,
There is no known method for efficiently producing ozone water by mixing ozone gas with water.

を含有するオゾン水が製造できることがわかった。From the experimental results shown in Tables 1 and 2, in the case of the conventional ozone producing apparatus, when the total flow rate of the water to be treated changes, the ozone gas and the water are not sufficiently mixed in the mixer. It is difficult to produce ozone water having a stable ozone concentration, but in the case of the ozone production apparatus of the present invention, some problems occur even in a wide range of flow rate, which was difficult with the conventional apparatus. It was found that ozone water containing ozone could be stably produced without any problem.
