Description

Detailed Description of the Invention

[0001]

[Industrial applications]

The present invention relates to an ozone sterilizer.

[0003]

[Prior Art and Problems to be Solved by the Invention]

[0004] In the field of aquaculture for aquaculture, sterilization of breeding water has been carried out by using ultraviolet rays or ozone to prevent diseases of breeding organisms.

When ozone is brought into contact with seawater, bromine ions in the seawater undergo a chemical change to form residual oxidant-containing water.

When ozone is brought into contact with fresh water,
Water containing dissolved ozone is produced.

Both the water containing residual oxidant and the water containing dissolved ozone have a strong bactericidal action and are used for sterilizing breeding water.

However, in order to completely prevent the occurrence of diseases, sterilization of breeding water is not enough, and it is necessary to disinfect the breeding aquarium in advance.

At present, the breeding aquarium is sterilized as follows.

(1) Sun drying

Although this has been generally practiced in the past, it cannot be said that a certain virus is inactivated sufficiently and the bactericidal effect is not sufficient, and it is necessary to further disinfect with a disinfectant solution. is there.

(2) Disinfection with chlorine

In this method, water containing a high concentration of free chlorine is filled in a water tank, sterilized for a sufficient time, neutralized with sodium thiosulfate, and the treated water is discharged to the outside.

In this case, not only was it inefficient because it took time to fill and release water in the aquarium, and some viruses may not be able to be sufficiently inactivated, and improvement is desired. Was there.

(3) Use of antiseptic solution

[0016] This is to inactivate a virus etc. by directly spraying a disinfecting solution such as sodium laurate on a water tank, but it is not sufficiently considered how to dispose the disinfectant solution. It could cause environmental pollution.

Therefore, there has been a demand for means for sterilizing the breeding aquarium that has a sufficient sterilizing effect, does not take much time, and does not pollute the environment.

[0018]

[Means for Solving the Problems]

The present inventor has conducted extensive studies to solve the above-mentioned problems, and by spraying residual oxidant-containing water or dissolved ozone-containing water directly on the aquarium, it is possible to inactivate pathogen organisms such as viruses in the aquarium. discovered.

Further, when the residual oxidant-containing water and the dissolved ozone-containing water are pumped by a pump and applied to the surface of the aquarium with a strong pressure, the residual oxidant-containing water and the dissolved ozone-containing water are sufficiently absorbed even between the cracks in the aquarium. It was also discovered that it penetrated and the inactivating effect was enhanced.

Further, it has been found that the above-mentioned means does not use a batch treatment like chlorine treatment but sterilization with pressure-fed water, so that the amount of water used is small and the time required for sterilization in an aquarium can be shortened.

The present invention has been completed based on the above findings.

That is, the means for solving the problems of the present invention are as follows.

Firstly, an ozone tank for sterilizing the breeding water by ozone treatment by ozone contact, and an activated carbon tank for detoxifying the ozone-treated water by the ozone tank by activated carbon treatment,

Secondly, an ozone tank for sterilizing the breeding water by ozone treatment by ozone contact and an activated carbon tank for detoxifying the ozone-treated water by the ozone tank by activated carbon treatment are provided.
A first supply pipe for supplying detoxified ozone-treated water that communicates with the activated carbon tank and a second supply pipe for supplying ozone-treated water that communicates with the ozone tank are provided so as to be switchable, and a pump for pumping pressure to the second supply pipe. Ozone sterilizer equipped with.

Thirdly, an ozone tank for sterilizing the breeding water by ozone treatment by ozone contact, an activated carbon tank for detoxifying the ozone-treated water by the ozone tank by activated carbon treatment, and a water storage tank are provided. A first supply pipe for supplying detoxified ozone-treated water that communicates with the tank and a second supply pipe for supplying ozone-treated water that communicates with the ozone tank and the water storage tank are provided so as to be switchable, and water storage that communicates with the water storage tank An ozone sterilizer provided with a third supply pipe for supplying water.

Fourth, an ozone tank for sterilizing the breeding water by ozone treatment by ozone contact, an activated carbon tank for detoxifying the ozone-treated water by the ozone tank by activated carbon treatment, and a water storage tank are provided. A first supply pipe for supplying detoxified ozone-treated water that communicates with the tank and a second supply pipe for supplying ozone-treated water that communicates with the ozone tank and the water storage tank are provided so as to be switchable, and water storage that communicates with the water storage tank An ozone sterilizer provided with a third supply pipe for supplying water, and a pump for pressure feeding provided on the third supply pipe.

The ozone sterilizing apparatus of the present invention can also be used by spraying ozone-treated water directly on passages, boots and the like.

The ozone-treated water mentioned here is treated water containing residual oxidant and dissolved ozone, and is not detoxified through an activated carbon tank.

Since the residual oxidant-containing water and the dissolved ozone-containing water obtained by the ozone treatment are self-decomposed or decomposed when exposed to sunlight, it is not necessary to detoxify them with sodium thiosulfate or the like.

Also, if the ozone-treated water that cannot be sufficiently decomposed by itself and has flowed out of the breeding aquarium is mixed with the organic substances in the drainage channel, it can be easily detoxified, and there is no problem of environmental pollution.

According to the ozone sterilizer of the present invention,
To sterilize the aquarium, without updating new equipment,
It is economical because it is possible to sterilize breeding water and sterilize the aquarium simply by modifying a part of the existing ozone sterilizer.

[0033]
