The present invention relates to a purified water and oxygen supply device, and more particularly to a purified water and oxygen supply device with a simple structure and improved usability.

In general, aquaculture tanks used to artificially raise fish are supplied with a suitable amount and quality of water (fresh water or seawater) and feed for farmed fish.

Therefore, in the culture tanks, fish droppings and food wastes in the tanks are continuously sinked. As a result, the water in the tanks becomes turbid, the dissolved oxygen in the water is insufficient, or the large amount of undesired microorganisms causes disease in fish. To prevent this, it is necessary to drain some of the water in the culture tank at regular intervals, clean the bottom and replenish the water, or continuously supply fresh water.

At this time, the water temperature is dropped by replacing the water in the culture tank at once, the cultured fish is stressed in the process of moving the cultured fish back to another place, and the growth is slow and the quality of the farmed fish falls.

On the other hand, with the recent depletion of global fisheries and the demand for high-quality fish, the farming of freshwater and saltwater fish has increased.

However, the cultured fish is densely specified in the culture tank formed in a certain space, and thus, the amount of the mixed fish is also supplied to the excess so that the fish farms, as well as the water turbidity caused by the foods left by the fish, are overcrowded. Due to the excreta, the water quality in the tanks was very quickly contaminated.

In addition, such water turbidity causes harmful microorganisms to cause various fish diseases, and it is difficult to maintain dissolved oxygen concentrations in the water suitable for farmed fish, resulting in uneven growth and development of farmed fish, resulting in poor quality and mortality. There was also a problem that increases.

In addition, water pollution of the aquaculture tanks is caused by the discharge of aquaculture tanks to improve the water quality of the aquaculture tanks. There was a problem that the maintenance is difficult, such as increase.

In order to solve the above problems, an object of the present invention is to provide a purified water and oxygen supply device with a simple structure and improved usability.
