Referring to fig. 1, a closed-loop aquaculture system 100 includes a plurality of aquaculture tanks 110, a water purification module 120, and a plurality of water pumping motors 130. The water purification module 120 communicates with the cultivation tank 110. The pumping motor 130 is connected between the cultivation tank 110 and the water purification module 120, and the pumping motor 130 is disposed corresponding to the cultivation tank 110. The pumping motors 130 are adapted to operate in turn.

The pumping motor 130 can pump the water in the culture tank 110 to the water purification module 120. The direction of water flow may be as shown by the arrows in fig. 1, but is not limited thereto. The closed loop farming system 100 may also include a plurality of transfer pipes T. One end of each delivery pipe T is connected to each cultivation tank 110, and the other end of each delivery pipe T is fixed to the water purification module 120. Each pumping motor 130 may be connected to each delivery pipe T to pump the water in each cultivation tank 110 to the water purification module 120 in turn, thereby maintaining the water quality in each cultivation tank 110. Incidentally, in the present embodiment, since the pumping motors 130 and the cultivation tanks 110 are arranged in a one-to-one manner, the operation power of each pumping motor 130 can be determined according to the requirement of each cultivation tank 110. For example, the operation power of the corresponding pumping motor 130 of the cultivation tank 110 far away from the water purification module 120 can be higher; on the contrary, the operation power of the corresponding pumping motor 130 of the cultivation tank 110 near the water purification module 120 can be lower.

Fig. 2 is a schematic view of the water purification module of fig. 1. Referring to fig. 1 and 2, the water purification module 120 can purify the water in the cultivation tanks 110 to maintain the water quality of each cultivation tank 110. In detail, the water purification module 120 may further include a first purification tank 121, a second purification tank 122, and a third purification tank 123. The second purge tank 122 is connected between the first purge tank 121 and the third purge tank 123. The pumping motor 130 is adapted to deliver the water in the cultivation tank 110 to the first purification tank 121. The first purge tank 121 has a first water outlet O1 communicating with the second purge tank 122. The second purge tank 122 has a second water outlet O2 communicating with the third purge tank 123. The third purification tank 123 has a third water outlet O3 connected to the culture tank 110. The height of the first water outlet O1 is greater than that of the second water outlet O2, and the height of the second water outlet O2 is greater than that of the third water outlet O3. For example, the water purification module 120 may be placed on the ground (not shown) at a height of the first water outlet O1, the second water outlet O2, and the third water outlet O3 compared to the ground. Thus, the water in the first purge tank 121 can flow through the second purge tank 122 and the third purge tank 123 sequentially through the potential difference.

In this embodiment, the water purification module 120 may further include a coarse filtration device F1 and a fine filtration device F2. The coarse filtration device F1 is connected between the cultivation tank 110 and the first purification tank 121. A fine filter device F2 is disposed in the third purifying tank 123. The filtration particle size of the fine filtration device F2 was smaller than that of the coarse filtration device F1. For example, the filtering particle size of the fine filtering device F2 can be between 100 and 150 micrometers, but is not limited thereto. In this embodiment, the coarse filtering device F1 may further include a dry-wet separation device 124. The wet and dry separating device 124 is connected between the cultivation tank 110 and the first purification tank 121, and primarily filters large impurities such as excrements or residual baits.

The water outlet O is adapted to inject water from the top of the first purification tank 121 toward the inside of the first purification tank 121. The caliber of each water outlet O is smaller than that of the water inlet I. Thus, the moisture-dry separator 124 can generate a large amount of water columns, and increase the oxygen-exposure efficiency by using the impact force generated when the water columns fall into the first purification tank 121.

The closed loop cultivation system 100 may further comprise two automatic valves 140 disposed at the water inlet of the first purification tank 121 and the water inlet of the third purification tank 123; for example, one of the automatic valves 140 may be disposed on the wet-dry separator 124, and the other automatic valve 140 may be disposed on the third water outlet O3 of the third purifying tank 123. The automatic valve 140 is adapted to close the water outlet O and the third water outlet O3 when the water levels in the first purifying tank 121 and the third purifying tank 123 reach a threshold value, so as to maintain the water pressure difference between the first purifying tank 121 and the third purifying tank 123. In detail, the water level of the first purge tank 121 is not excessively low, and the water level of the third purge tank 123 is not excessively high, but other embodiments are not limited thereto. In this embodiment, the automatic valve 140 can be mechanically controlled, for example, by providing a float (not shown) on the water surface of the first and third purge tanks 121 and 123 to detect the water level and close the automatic valve 140. In other embodiments, the automatic valve 140 can be controlled in an electrically controlled manner, and the present invention is not limited to the specific manner of controlling the automatic valve 140.

The second purification tank 122 contains, for example, a biological purification agent. The biological decontaminant may include nitrifying bacteria, but is not limited thereto. Furthermore, the water purification module 120 comprises, for example, a deproteinization device RP. The deproteinizing device RP is connected to the second purifying tank 122, and the water in the second purifying tank 122 is pumped to the deproteinizing device RP by the water pump M1 to remove the proteins in the water in the second purifying tank 122. In detail, the deproteinizing device RP of the present embodiment may include a protein defoaming device R. The protein defoaming device R is operated to generate a large amount of foam in the water in the second purification tank 122, and the foam floats on the water surface. On the other hand, the impurities in the second cleaning tank 122 are deposited to the bottom. In order to introduce the clean water in the second purification tank 122 into the third purification tank 123, the second water outlet O2 may be located at the waist of the second purification tank 122, so that the foam and impurities are prevented from flowing into the third purification tank 123 in a large amount.

The water purification module 120 may also include an industrial filtration device 125. An industrial filtering device 125 is connected between the third purifying tank 123 and the cultivation tank 110 (shown in fig. 1) to filter the water in the third purifying tank 123.

In the present embodiment, the industrial filter device 125 can filter fine particles having a smaller filtering particle size than the fine filter F2, but is not limited thereto.

Fig. 3 is a schematic top view of the habitat of fig. 1. Referring to fig. 3, the cultivation tank 110 is capable of supplying aquatic organisms to grow and reproduce. Thus, the closed loop aquaculture system 100 (labeled in FIG. 1) also includes, for example, a plurality of water quality monitoring devices 150. The water quality monitoring devices 150 are respectively disposed in the cultivation tanks 110 so as to monitor the water quality of the cultivation tanks 110. Specifically, the water quality monitoring device 150 can monitor the ph, dissolved oxygen content, salinity and/or water temperature of the water, but is not limited thereto. In addition, the closed-loop cultivation system 100 further includes a plurality of image capturing devices 160.

Similar to the first and third purification tanks 121 and 123, the water inlet of the cultivation tank 110 may be provided with an automatic valve 140 to prevent the water level in the cultivation tank 110 from being too high due to blockage and even overflowing.

The closed loop aquaculture system 100 may also include a plurality of oxygenation devices 170. The oxygen increasing devices 170 are respectively arranged in the culture tanks 110. In detail, the oxygen increasing device 170 can generate a large amount of oxygen to the water in the cultivation tank 110 to increase the oxygen aeration efficiency. Further, in the present embodiment, the oxygen increasing devices 170 may each include a microbubble generation element 171. The culture tank 110 may be cylindrical in shape, and each microbubble generation element 171 generates microbubbles along the sidewall and bottom of each culture tank 110, for example. For example, the microbubble generator 171 in the figure can eject microbubbles along the tangential direction D1 of the sidewall of the cultivation tank 110 and the direction D1a toward the bottom of the cultivation tank 110, so that the microbubble generator 171 can also form a vortex-like water flow in the cultivation tank 110, so that impurities in the water can be concentrated to the center of the cultivation tank 110 for discharging the sewage. In another embodiment, such as shown in fig. 4, the cultivation tank 110a may have a rectangular parallelepiped shape, the microbubble generation elements 171 may be respectively disposed at one side E1 in the cultivation tank 110a, and each microbubble generation element 171 is adapted to generate microbubbles toward the opposite side E2 from the one side E1. For example, the microbubble generator 171 shown in the figure is disposed on the short side wall W1 in the cultivation tank 110a, and may eject microbubbles toward the other short side wall W2 in the direction D2, wherein the direction D2 may be substantially perpendicular to the short side wall W1, but is not limited thereto. Thus, the microbubbles can flow along the inner edge of the culture tank 110 a.

Therefore, the closed-loop aquaculture system 100 of the present embodiment can maintain the ecology of the aquaculture tank 110 with only a small amount of water and can effectively reduce the amount of sewage discharged, thereby providing advantages of low cost and environmental protection. For example, the conventional open circulation aquaculture system requires 2 to 3 times of the total volume of the aquaculture tank, while the closed circulation aquaculture system 100 of the present embodiment only requires about 30% to 50% of the total volume of the aquaculture tank 110 to maintain the ecology of the aquaculture tank 110. In addition, since the pumping motors 130 of the present embodiment are operated alternately, the water in the single cultivation tank 110 can be pumped efficiently for circulation. Thus, the power required for each operation of the pumping motors 130 can be reduced, thereby reducing the power consumption. Additionally, the closed-loop cultivation system 100 of the present embodiment can be configured with about 150 to 200 tons of water; the above-mentioned amount of water can reduce the risk of collectively infecting diseases of aquatic organisms in the culture tank 110, and is also advantageous in adjusting the culture quantity and kind of aquatic organisms to provide a good economic effect. In addition, the closed-cycle aquaculture system 100 of the present embodiment can effectively maintain the water quality of the aquaculture tank 110, and allow aquatic organisms to stably grow. Therefore, aquatic organisms in the middle breeding period can be thrown in, the breeding period is shortened, a rolling type breeding mode of multiple harvest is formed, and the production can be planned and improved. For example, the conventional cultivation method can be harvested only 1-2 times a year, and the closed-loop cultivation system 100 of the present embodiment can be harvested 3-4 times a year, so as to effectively increase the productivity and the yield.
