【Example】

An embodiment of the ozone sterilization and breeding apparatus of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic view of Embodiment 1 of the ozone sterilization breeding apparatus of the present invention.

FIG. 2 is a schematic view of Embodiment 2 of the ozone sterilization and breeding apparatus of the present invention.

First, a first embodiment will be described with reference to FIG.

The ozone sterilization and breeding apparatus of Example 1 comprises ozone contact means for producing ozone-containing water or oxidant-containing water by mixing ozone gas 11 in the mixing section 12, and the leading end side is the intake port 13 and the rear end side is the breeding water tank. A water supply pipe 15 communicating with the water supply pipe 14, an ozone-containing water or oxidant-containing water detoxification treatment means for detoxifying ozone-containing water or oxidant-containing water by a detoxifier 16 attached to the breeding aquarium 14 side of the water supply pipe 15, and breeding A water tank 14 is provided, and the ozone-containing water or the oxidant-containing water generated by the ozone contacting means is rendered harmless by the harm remover 16 immediately before being injected into the breeding water tank 14 through the water supply pipe 15, and the harmless The converted water is used as breeding water, but the ozone-containing water or oxidant-containing water generated by the ozone contacting means is sent. 15 into the breeding aquarium 14 to sterilize and purify the inside of the breeding aquarium 14, then remove the ozone-containing water or the oxidant-containing water, and newly supply the ozone-containing water or the oxidant-containing water via the water supply pipe 15. It is also possible to detoxify it with the abatement device 16 before injecting it into the water, and use the detoxified water as breeding water.

In FIG. 1, reference numeral 17 denotes a pump installed between the water intake 13 and the mixing portion 12 in the middle of the water supply pipe 15.

When breeding water is taken in through the intake port 13,
It is sent to the pump 17 through the water supply pipe 15.

In the mixing portion 12, which is an arbitrary portion of the water pipe 15 from the passage of the pump 17 to the abatement device 16,
Ozone gas 11 is brought into contact with the breeding water.

The contact method may be a method in which ozone gas 11 is mixed with breeding water by an injector, or a method in which a contact cylinder is provided in advance and ozone gas 11 is injected by a diffuser plate to bring them into contact with each other, or ozone is made into a liquid The contacting method may be any of the existing methods.

When the treated water is seawater, ozone forms a residual oxidant. In this case, the oxidant concentration is preferably 0.1 ppm or more.

In the case of fresh water, the dissolved ozone concentration is
It is desirable that the content is at least 0.1 ppm or more.

Here, the ozone-containing state in the case of fresh water or the oxidant-containing state in the case of seawater is
Water pipe after ozone contact 1 so that it lasts more than 0.5 minutes
It is desirable to pipe 5.

When the dissolved ozone-containing water and the residual oxidant-containing water reach the front of the breeding aquarium 14, the abatement device 16 removes the dissolved ozone and the residual oxidant, and the breeding aquarium 14
Is supplied to.

As the detoxifier 16, it is effective to use air aeration in the case of fresh water and to pass activated carbon in the case of seawater.

At this time, the dissolved ozone concentration is 0.003 pp
m or less, and the residual oxidant concentration needs to be 0.07 ppm or less.

As described above, in addition to the sterilization of breeding water, the inside of the water supply pipe 15 and the like can be sterilized.

This is a great advantage of this device,
For example, an ultraviolet sterilizer that is often used for sterilizing breeding water cannot sterilize the inside of the pipe.

In addition, chlorine sterilization allows sterilization in a tube, but it has little effect on virus inactivity, and it is difficult to remove it with other chemical substances or chemicals.

When the breeding aquarium 14 is sterilized prior to breeding, the residual oxidant-containing water or the dissolved ozone-containing water is directly injected into the breeding aquarium 14 without passing through the abatement device 16 to facilitate the sterilization. It can be sterilized and breeding organisms can be kept safely.

Next, a second embodiment will be described with reference to FIG.

The ozone sterilization breeding apparatus of the second embodiment is an application example of the first embodiment, and the ozone contact means for producing the ozone-containing water or the oxidant-containing water and the water intake port 23 on the front end side.
The water supply pipe 25 whose rear end side communicates with the breeding water tank 24 and the abatement device 26 attached to the water feeding pipe 25 on the breeding water tank 24 side
The ozone-containing water or oxidant-containing water is rendered harmless by means of ozone-containing water or oxidant-containing water detoxification treatment means, and a breeding aquarium 24. It is injected from the water intake port 23, or ozone gas is directly injected into the water intake port 23 to generate ozone-containing water or oxidant-containing water. These ozone-containing water or oxidant-containing water are supplied through the water pipe 25. Immediately before injecting into the breeding aquarium 24, detoxify with a harm remover 26,
The detoxified water is used as breeding water, and the ozone-containing water or the oxidant-containing water generated by the ozone contacting means is injected into the breeding aquarium 24 by the water supply pipe 25, and after sterilizing and purifying the inside of the breeding aquarium 24, Before the ozone-containing water or the oxidant-containing water is removed and the ozone-containing water or the oxidant-containing water is newly injected into the breeding aquarium 24 via the water supply pipe 25, it is detoxified by the abatement device 26, and the detoxified water is removed. It can also be used as breeding water.

When sterilizing and purifying the inside of the breeding aquarium 24,
The breeding aquarium 24 can be easily sterilized, and breeding organisms can be safely breeded.

In FIG. 2, 27 indicates a pump installed in the middle of the water supply pipe 25.

Reference numeral 28 denotes an activated carbon tank installed between the pump 27 and the detoxifier 26, and 29 denotes a sand filter tank installed between the pump 27 and the detoxifier 26. There is.

The ozone gas 21 can be injected from the water intake 23 as shown in FIG. 2, or can be injected in the water supply pipe 25 (not shown).

The injection of the ozone gas 21 from the water intake port 23 also serves to prevent biological adhesion of the water intake port 23.

Instead of injecting the ozone gas 21, residual oxidant-containing water or ozone-containing water may be injected.

In the aquaculture system and the like, the breeding water is often used after sand filtration, but in this case, the residual oxidant and the ozone content are measured by passing through the activated carbon tank 28 or performing air aeration before the sand filtration. Can be used after being reduced to about 0.01 to 1.0 ppm.

At this time, the residual oxidant concentration is preferably at least 0.1 ppm or more, and the dissolved ozone concentration is preferably at least 0.1 ppm or more.

By injecting the ozone gas 21 or the oxidant-containing water from the water intake port 23 when the breeding water is taken in from the water intake port 23, the breeding water is sterilized and the adhered organisms are controlled.

The ozone-containing water or the residual oxidant-containing water passes through the water supply pipe 25 and reaches the sand filter tank 29. During this time, sterilization is performed with the ozone-containing water or the residual oxidant-containing water.

The ozone-containing water or the residual oxidant-containing water may be reduced in the activated carbon tank 28 or the like prior to sand filtration, but this helps the detoxification treatment just before the breeding aquarium 24 to be performed more safely.

Naturally, it is necessary to ensure that the oxidant concentration or ozone concentration after passing through the sand filtration tank 29 is 0.1 ppm or more.

As the detoxifier 26, it is effective to use air aeration for fresh water and to pass activated carbon for seawater.

At this time, the dissolved ozone concentration is 0.003 pp
m or less, and the residual oxidant concentration needs to be 0.07 ppm or less.
