Embodiments of the present invention will be described below in detail with reference to the drawings.

Embodiment 1 FIG. 1 is a schematic view showing a water treatment apparatus 10 for producing water without dissolving ozone and oxygen. In the figure,
Water from the tap water is stored in a water tank 14 provided on the roof of a building or the like through an existing pumping pipe 12. The water in the water tank is sent to an ozone dissolution tank 18 through a water supply pipe 16. The ozone dissolving tank 18 dissolves ozone generated from the ozone generator 20 in water in which molecules such as oxygen are dissolved. Here, ozone-dissolved water having an ozone concentration of 1 ppm or more, preferably 4 ppm or more is generated. The supply amount of ozone is adjusted by the controller 22.

Next, the water having this concentration of ozone dissolved therein is sent through a water supply pipe 16 to a dissolved gas molecule removing device, for example, a degassing device 24. The deaerator 24 deaerates water in which ozone and oxygen are dissolved under reduced pressure. Therefore, water that does not dissolve molecules such as ozone and oxygen is generated. Then, chlorine generated in the chlorine generator 26 is added to water in which ozone and oxygen are not dissolved, and the water is sent to the existing distribution water pipe 27. As a method for removing ozone molecules from water in which the ozone molecules are dissolved, a permeable membrane or the like can be used in addition to the above-described reduced pressure.

The ozone dissolving tank 18 dissolves ozone generated from the ozone generator 20 in water.
Water in which molecules such as ozone and oxygen generated from the ozone generator are dissolved is supplied to the tank. Here, it is preferable that the pipe for supplying ozone and the pipe for supplying the water are double pipes, and ozone and water are simultaneously supplied into the tank. The tank is provided with a stainless steel plate member 28 formed in a strip shape to increase the contact distance between the water and ozone or to increase the contact time. Ozone is dissolved in the water while the water moves from the top to the bottom on the plate member 28.
The concentration of ozone is 1 ppm or more, preferably 4 ppm or more. Note that the present invention is not limited to this embodiment as long as it can obtain such an ozone concentration. For example, a rotating device may be provided in the ozone dissolving tank to supply water to the device, or the ozone dissolving tank may be cooled to a low temperature or further pressurized.

Further, water containing ozone can be taken out from an ozone generator 20 provided in the ozone dissolving tank 18.

The deaerator 24 is a container maintained in a reduced pressure state. The container is held in a reduced pressure state by a vacuum pump 30. The vacuum vessel is at atmospheric pressure, ozone,
A water supply pipe 16 for introducing water in which molecules such as oxygen are dissolved is provided. Water in which molecules such as ozone and oxygen are dissolved is sent to a water discharge pipe 32. The water discharge pipe 32 has a nozzle 34 at its tip. The nozzle 34 has ozone,
Water in which molecules such as oxygen are dissolved is ejected in the form of fine particles. Then, molecules such as ozone and oxygen dissolved in water are degassed under reduced pressure. Note that the concentration of the solvent dissolved in water, that is, ozone and oxygen, decreases in proportion to the atmospheric pressure. The pressure inside the vacuum vessel is reduced to about 60 Torr. Thus, the deaerator reduces the dissolved concentration of oxygen in the water to 2.0 p.
pm or less, preferably 1.0 ppm or less.

Then, molecules such as ozone and oxygen ejected from the nozzle move upward in the vacuum vessel and are discharged from the exhaust valve 36 to the outside of the vessel. On the other hand, water that does not dissolve oxygen accumulates in the lower part of the container. Then, the water is discharged from the discharge port. Further, the apparatus is provided with a removing device 38 for preventing oxygen, nitrogen and the like discharged to the upper portion thereof from being released to the atmosphere.

The ozone generator generates ozone using oxygen molecules and ozone molecules exhausted from the deaerator. At this time, the gas containing the oxygen molecules and the ozone molecules exhausted from the deaerator is preferably dried before being supplied to the ozone generator. If the amount of oxygen molecules and ozone molecules exhausted from the deaerator is smaller than the amount required to generate ozone, an ozone generator that generates ozone from air or the like in the atmosphere is used together.

Embodiment 2 FIG. 2 is a schematic diagram showing a water treatment apparatus 50 for producing sterilized drinking water in which molecules such as ozone and oxygen are not dissolved. In this figure, water from the tap water is stored in a water tank 14 provided on the roof of a building or the like through the existing pumping pipe 12 as described above. The water in the water tank is sent to the deaerator 52 through the water supply pipe 16. Here, molecules such as oxygen dissolved in tap water are degassed under a reduced pressure of a dissolved gas molecule removing device, for example, a degassing device 24. Therefore, water that does not dissolve molecules such as oxygen is generated.

Next, the water in which molecules such as oxygen are not dissolved is supplied to the ozone dissolving tank 54 through the water supply pipe 16. Here, ozone generated from the ozone generator 20 is dissolved in water in which molecules such as oxygen are not dissolved. The supply amount of ozone is adjusted by the adjuster 22. Thus, ozone-dissolved water having an ozone concentration of 1 ppm or more, preferably 4 ppm or more is generated in the ozone-dissolving tank. Then, water in which ozone is dissolved at this concentration is sent to the second deaerator 56. Thus, the deaerator 56 degass ozone molecules under reduced pressure. Thus, water free of molecules such as oxygen and ozone is obtained from the deaerator 56. This water is sent to the existing distribution water supply pipe 27. This water can be used as drinking water. In the configuration of the apparatus, it is also possible to take out the water in which the ozone obtained in the ozone dissolving tank 54 is dissolved and send it to the existing distribution water supply pipe 40.

The first and second deaerators, the ozone dissolving tank, and the ozone generator have the same configuration and operation as those of the first embodiment, and therefore the description is omitted. In this embodiment, one ozone dissolving device is used through the first degassing device.
Water containing ozone having an ozone concentration of at least 4 ppm, preferably at least 4 ppm is obtained. Then, this water is sent to the second deaerator. In the second deaerator,
Water in which ozone molecules are dissolved is ejected from the nozzle 34 in the form of fine particles. Then, the ozone molecules dissolved in the water are degassed under reduced pressure.

The ozone generator generates ozone using oxygen molecules exhausted from the first deaerator and ozone molecules exhausted from the second deaerator. As described above, it is preferable that the gas containing the oxygen molecules and the ozone molecules exhausted from the deaerator is dried before being supplied to the ozone generator. If the amount of oxygen molecules and ozone molecules exhausted from the deaerator is smaller than the amount required to generate ozone, an ozone generator that generates ozone from air or the like in the atmosphere is used together. Is also good.

Here, ozone generated from the ozone generator 20 is dissolved in water in which molecules such as oxygen are not dissolved. The supply amount of ozone is adjusted by the adjuster 22. Thus, ozone-dissolved water having an ozone concentration of 1 ppm or more, preferably 4 ppm or more is generated in the ozone-dissolving tank.

The sterilized water in which ozone molecules are dissolved is
