を図つている。[Prior art] In order to maintain dissolved oxygen in the water, conventional aquariums for aquatic organisms perform aeration by blowing air into the water from an air pump, or use the air from the air pump as an air lift to maintain the dissolved oxygen in the water. A method of aeration above the water surface is known. Also known is a method of supplying oxygen into water from an oxygen cylinder via a pressure regulating valve by aeration. In this method of supplying oxygen to water,
Utility Model Publication No. 58-137064 or Special Publication No. 52-47743
As seen in the above publication, an attempt is made to increase the amount of dissolved oxygen by partially raising the pressure of the oxygen dissolving part to above atmospheric pressure.

Conventional aquariums for rearing aquatic organisms are at atmospheric pressure, and the amount of dissolved oxygen in the water at atmospheric pressure is limited by the water temperature, specific gravity, etc., for example, as shown in Figure 3a. The oxygen partial pressure of the air in a normal aquarium is 0.21 atm, and the amount of dissolved oxygen is limited to about 5 c.c./cm.

Furthermore, even when oxygen cylinders are used, there are problems in that high-pressure oxygen is dangerous and there are safety issues, and oxygen cylinders are difficult to obtain on remote islands or in far-flung areas.

を有している。 In addition, even in the conventional method described above where the oxygen dissolving part is partially raised to above atmospheric pressure, the tank itself is at atmospheric pressure, and although it is possible to temporarily increase the amount of dissolved oxygen slightly, the oxygen supply is limited. If it runs out, the amount of dissolved oxygen at atmospheric pressure is limited, so the oxygen will be released into the air, necessitating a correspondingly larger oxygen cylinder.

The purpose of the present invention is to provide a pressure water tank for aquatic organisms that can improve the effects of water treatment.

In the present invention, for example, as shown in FIG. 3b, an air compressor is driven to pressurize the water in the aquarium and the gas in contact with the water, and as the pressure increases, the oxygen partial pressure in the gas rises. This increases the amount of dissolved oxygen in the water tank 2. For example, when pressurized to a gauge pressure of 3 Kg/ cm2 , the oxygen partial pressure of pressurized air is 0.84 atm, which means that the air contains four times as much oxygen as atmospheric pressure. Gas is dissolved in the water that comes into contact with this pressure air, and the amount of dissolved oxygen in the water is 4
It will increase twice.
