FIG. 2 is a block diagram showing an apparatus for increasing dissolved oxygen in water according to a second embodiment of the present invention. In this example,
A coil 5 and a magnet 6 are arranged around the solid-phase and gas-phase contact device 2 in the first embodiment, and an electric current flows through the coil 5 to electromagnetically act on oxygen passing through the solid-phase and gas-phase contact device 2. And a magnetic field generated by the magnet. Other configurations are the same as those of the first embodiment, and the same reference numerals are given to the same members in the first embodiment, and the detailed description will be omitted.

In the apparatus shown in FIG. 2, in order to activate the oxygen generated by the oxygen generator 1, it is brought into contact with a catalyst such as titanium oxide and a magnetic field is applied. Oxygen may be activated by the above-mentioned means or by using these means in combination.

According to the apparatus of the above embodiment, the dissolved oxygen is 3 to
5p. p. m of tap water, in the first embodiment, the dissolved oxygen is 35 p. p. m, and in the second embodiment, 70 p. p. m. Further, when tap water having an oxidation-reduction potential (ORP value) of +600 mV was treated, the oxidation-reduction potential was reduced to +200 mV in the first embodiment and the second embodiment. Furthermore, when tap water of ph 6.9 was treated, ph was 7.6 in the first embodiment and ph 9.0 in the second embodiment.

Next, the use of water treated by the above embodiment will be described. First, an emulsion fuel as application 1 will be described. Water and mineral oil, in which the dissolved oxygen is increased by the apparatus for increasing dissolved oxygen in water, are mixed 1: 1, a small amount of a surfactant is added, and the mixture is stirred. When the emulsion fuel thus produced was burned, the temperature could be maintained at about the same level as when only mineral oil was burned, and NOx and SOX could be significantly reduced, and CO ₂ could also be reduced.

When the above-mentioned emulsion fuel is used as fuel for an engine, the combustion efficiency can be increased by mixing oxygen discharged in the form of bubbles with a device for increasing dissolved oxygen in water into intake air of the engine.

Next, a medium for transferring live fish as use 2 will be described. As a result of bred in water with increased dissolved oxygen by the apparatus for increasing dissolved oxygen in water in the example, and shrimp, crab, and the like were transported by land, there was no discoloration at the time of arrival three days later, deterioration in freshness, skinnyness, etc., 100% survived.

Further, when used as a medium for transporting live fish, discoloration, deterioration of freshness, body weight, and the like can be prevented, and the survival rate can be increased.

When used as drinking water, there is a bacteriostatic effect, so that prevention of disease can be expected. Furthermore, when used for blood removal of Kazunoko and the like, blood removal can be performed at a lower cost than conventional methods.

When used in the enzyme industry, the enzyme can be controlled and the quality of the product can be improved. Furthermore, when used for agriculture, a large amount of oxygen can be supplied with a small amount of water, so that field cultivation in arid regions or deserts is possible. Furthermore, when used in hydroponics, the circulating water is rich in oxygen, which is effective in preventing rot and replenishing nutrients, and growing healthy vegetables. In addition, crops can be prevented from dying in the event of a flood.

When used for kneading concrete, the strength increases and the amount of cement used decreases. In addition, water
A decrease in the cement ratio (increase in fluidity) reduces the rate of infiltration and increases cold resistance. Further, the fuel mixed with alcohol makes it possible to use waste oil or the like as fuel.
