Freshwater/Artificial Seawater Farm with Natural Purification Function {FRESH WATER AND SEA WATER FISH FARM HAVING NATURAL PURIFICATION FUNCTION}

The present invention relates to a freshwater/artificial seawater (non-seawater) aquaculture farm having a natural purification function. It's about the farm.

In general, in the case of aquaculture, contaminants are continuously added while water is stagnant, and water quality deteriorates over time. Even if a treatment facility is installed, the treatment facility only serves as aeration, which only supplies air, and only supplies oxygen to the water.

The method of purifying the farm by such a farm purification device is to introduce aquaculture water inside the farm to a general filter using a suction pump, then send the treated water purified from the filter to a treatment tank, and discharge it back to the farm. it was

And in order to drain the sludge stuck inside the filter to the outside, the treated water in the treatment water tank was introduced into the filter using a backwash pump.

Such a technology related to aquaculture has been proposed in Korean Patent Registration No. 1604699.

However, Patent Document 1 has a problem in that it is not environmentally friendly because it is necessary to use an artificial purification device to purify foreign substances generated in the process of cultivating fish.

In this way, when the aquaculture farm 100 having a natural purification function according to the present invention is applied to an indoor sea fishing spot and a children's tidal shore experience center, it can be utilized in a comfortable indoor natural ecology as a countermeasure against serious air pollution (fine dust, yellow sand, etc.).

As described above, the operation process of the freshwater/artificial seawater aquaculture farm 100 having a natural purification function according to the present invention will be described as follows.

First, the temperature of the breeding water is controlled by the first and second cold and hot water supply units 1130 and 1230 according to the season in a state in which fish are reared in the first breeding tank 110 and the second breeding tank 120 . Possibly, the breeding water is rotated in the circular first and second breeding tanks 110 and 120 by the first and second rotation water flow units 1140 and 1240 .

Next, foreign substances generated in the first breeding tank 110 during breeding move to the water level control/foreign substance settling treatment chamber 132a through the first discharge pipe 112 , and breeding water flows through the first connection pipe 114 . It moves to the water level control/foreign substance precipitation treatment chamber (132a) through the.

Next, the foreign substances that have moved into the water level control/foreign substance precipitation treatment chamber 132a are deposited on the floor, and the breeding water containing the non-precipitated foreign substances passes through the first filtering space 132 with microorganisms such as bacteria. The water quality is purified by

Next, the breeding water whose water quality has been purified is moved to the second filtration space 134 by the first pump 140a to the high water level, and the water level of the first filtration space 132 is lowered almost to the bottom.

Next, when the purified breeding water moves to the second filtration space 134 , the second filtration space 134 and the second breeding tank 120 connected through the second connection pipe 124 are also filled by the same height. .

Conversely, foreign substances generated during the breeding process of fish in the second breeding tank 120 are moved to the water level control/foreign substance settling treatment chamber 134a through the second discharge pipe 122, and the breeding water is transferred to the second connection pipe. It moves to the water level control/foreign substance precipitation treatment chamber 134a through 124 .
