[0032] Please see Figures 1 to 12 This utility model provides a new type of rice-fish farming facility, including a pond 1. In this embodiment, the water area of ​​the pond 1 is 3 mu and the water depth is 2 meters. The aquaculture facilities also include a steel frame 2 located in the center of the pond 1, and the steel frame 2 is connected to the bank of the pond 1 by a steel bridge 3.

[0033] The steel frame 2 has several installation areas, each containing a canvas-made silo. These silos are divided into aquaculture silos 4 and sedimentation silos 5. Aquaculture silos 4 are used to raise chub, bass, or mandarin fish. The upper edges of both aquaculture silos 4 and sedimentation silos 5 are connected to the steel frame 2 via PVC cable ties. The steel frame 2 is constructed from hot-dip galvanized pipes, each 100mm x 100mm in length and width, and 3mm thick. The steel frame 2 is 17m long, 17m wide, and 2m high. Nine aquaculture silos 4 and seven sedimentation silos 5 are evenly distributed within the steel frame 2, each 3m in length and width. A 1-meter-wide grating walkway, 38mm thick, with 38mm x 38mm squares, is laid around the steel frame 2 and between the aquaculture silos 4 and sedimentation silos 5.

[0034] Each of the aquaculture tanks 4 has a first water exchange port 41 on its side wall, which allows water in the aquaculture tank 4 to flow with water in the pond 1. The sedimentation tanks 5 are connected in sequence, and all the aquaculture tanks 4 are connected to the first-stage sedimentation tank 5. The last-stage sedimentation tank 5 has a second water exchange port 51. The bottom of the sedimentation tank 5 is connected to the sludge collection tank 6 through a sludge discharge component. The sludge collection tank 6 is located on the bank. The upper part of the sedimentation tank 5 is a cubic structure, and the lower part is a conical structure.

[0035] The aquaculture chamber 4 is divided into an aquaculture area 42 and a waste sedimentation area 43 located below the aquaculture area 42. The aquaculture area 42 has a cubic structure, and the waste sedimentation area 43 has a conical structure. The dimensions of the aquaculture area 42 are 3m*3m*1.2m, and the maximum height of the waste sedimentation area 43 is 0.75m.

[0036] A first water exchange port 41 with a diameter of 110 mm is opened on each of the four side walls of the aquaculture area 42. The first water exchange port 41 on each side wall is set in two rows, one above the other, with two first water exchange ports 41 in each row. The distance between the first water exchange ports 41 in the upper and lower rows is 0.1 m, and the distance between the first water exchange port 41 in the upper row and the upper edge of the aquaculture area 42 is 0.2 m.

[0037] In this embodiment, seven sedimentation tanks 5 are provided, numbered sequentially from the first to the seventh stage. The waste sedimentation areas 43 in all aquaculture tanks 4 are connected to the first-stage sedimentation tank 5, used to discharge solid waste generated from aquaculture into the sedimentation tank 5. The first to seventh stage sedimentation tanks 5 are connected by PVC pipes 7 with a diameter of 110mm, and adjacent sedimentation tanks 5 are connected by four PVC pipes 7, each divided into upper and lower rows with a spacing of 100mm between the upper and lower rows. The distance between the upper row of PVC pipes 7 and the upper edge of the sedimentation tank 5 is 200mm. The first to sixth stage sedimentation tanks 5 are not connected to the water in the pond 1. The second water exchange port 51 is located on the side wall of the seventh-stage sedimentation tank 5. When the solid waste in the sedimentation tank 5 is discharged to the waste collection tank 6, water from the pond 1 can be replenished into the sedimentation tank 5 through the second water exchange port 51. The second water exchange port 51 is arranged in two rows, one above the other, with each row containing two second water exchange ports 51. The distance between the two rows of second water exchange ports 51 is 0.1m, and the distance between the second water exchange port 51 in the upper row and the upper edge of the sedimentation tank 5 is 0.2m.

[0038] The sludge collection bin 6 also includes a bin body made of canvas and a support frame made of PVC pipe, with the bin body fitted inside the support frame.

[0039] Each of the sedimentation chambers 5 and the outer side of the steel frame 2 is also provided with a floating plate assembly 8 for planting hydroponic rice. The area surrounding the steel frame 2 in pond 1 is also stocked with silver carp, bighead carp, crucian carp, and snails for water purification. The stocking density is as follows: 50 silver carp per mu (approximately 0.067 hectares), each weighing 250g; 50 bighead carp per mu (approximately 0.067 hectares), each weighing 250g; 300 crucian carp per mu (approximately 0.067 hectares), each weighing 50g; and 20 kg of snails per mu (approximately 10 kg per acre), with 200 snails per kg.

[0040] Specifically, the installation area has 16 compartments, which are divided into 9 aquaculture compartments 4 and 7 sedimentation compartments 5.

[0041] Specifically, the bottoms of the aquaculture tank 4 and the sedimentation tank 5 are conical structures.

[0042] Specifically, such as Figure 2 and Figure 7 As shown ( Figure 2 Due to the size limitation of the drawing, only a single aquaculture tank connected to the first-stage sedimentation tank is shown. The bottom of the aquaculture tank 4 is connected to the first-stage sedimentation tank 5 through a sludge suction assembly, which includes a sludge suction pipe 9 and a first sludge suction pump 10. The suction pipe 9 is connected to the drain outlets at the bottom of the three aquaculture tanks 4, and a first suction pump 10 is installed on the suction pipe 9. One end of the suction pipe 9 is connected to the first-stage sedimentation tank 5, and the other end is connected to the first water pressure balance control valve 11. The first water pressure balance control valve 11 is used to control the balance of the water level inside and outside the aquaculture tank 4 when water is initially introduced. The first water pressure balance control valve 11 is closed when the water level rises to the normal position before aquaculture can be started.

[0043] like Figure 7 As shown, nine breeding chambers 4 are arranged in three horizontal rows. Each breeding chamber 4 in each horizontal row is equipped with a set of sludge suction components connected to the first-stage sedimentation chamber. That is, the three breeding chambers 4 located in the same row are connected to the first-stage sedimentation chamber 5 through the same sludge suction pipe 9. The first sludge suction pump 10 is started periodically to discharge the solid waste deposited in the sludge sedimentation area 43 to the sedimentation chamber 5 through the sludge suction pipe 9.

[0044] During aquaculture, the water level in the pond will overflow the first and second water exchange ports. Therefore, the various sedimentation tanks are connected by PVC pipes 7, so that the fixed waste discharged into the first sedimentation tank 5 can flow to the various sedimentation tanks through PVC pipes 7.

[0045] Specifically, such as Figure 3 As shown ( Figure 3 Due to space limitations, only a single sedimentation tank and sludge collection tank connection are shown. The sludge discharge assembly includes a sludge discharge pipe 12 and a second sludge suction pump 13. The sludge discharge pipe 12 is connected to the sludge discharge port at the bottom of the seven sedimentation tanks 5, and the second sludge suction pump 13 is installed on the sludge discharge pipe. One end of the sludge discharge pipe 12 is connected to the sludge collection tank 6, and the other end is connected to the second water pressure balance control valve 14. The second water pressure balance control valve 14 is used to control the water level balance inside and outside the sedimentation tank 5 during the early water intake. The second water pressure balance control valve 14 is closed when the water level rises to the normal position before aquaculture can be started.

[0046] The second suction pump 13 is started periodically to discharge the solid waste deposited at the bottom of the sedimentation tank 5 to the sludge collection tank 6. Since the drain pipe 12 is connected to the seven sedimentation tanks 5, the solid waste in the seven sedimentation tanks is discharged together into the sludge collection tank 6 after the second suction pump 13 is started.

[0047] Specifically, each of the aforementioned aquaculture chambers 4 has an aquaculture net cage 15 on its inner side. The upper part of the aquaculture net cage 15 can also be fixed to the steel frame 2 with cable ties. The aquaculture net cage 15 is also connected to a net cage support frame 16, which is fitted onto the bottom of the aquaculture net cage 15 to support the bottom of the aquaculture net cage 15. The aquaculture net cage 15 is made of soft and durable nylon rope, and the mesh size of the aquaculture net cage 15 is 5mm. The aquaculture net cage 15 is located within the aquaculture area 42, and the net cage support frame 16 is spliced ​​from PVC pipes with a diameter of 32mm. The use of the aquaculture net cage 15 and the net cage support frame 16 can isolate the farmed fish fry from the conical structure at the bottom of the aquaculture chamber 4, preventing the fish fry from moving and scattering solid waste.

[0048] Specifically, it also includes an aeration assembly, which includes a Roots blower 17 and an aeration pipe 18. The Roots blower 17 is mounted on the steel frame 2, and the aeration pipe 18 is suspended in the middle layer of the water inside the aquaculture cage 15, connected to the Roots blower 17. The Roots blower 17 and the aeration pipe 18 can ensure the oxygen supply required for high-density aquaculture, ensuring that the dissolved oxygen level is not lower than 6 mg / mL. By suspending the aeration pipe 18 in the middle layer of the water, sufficient oxygen supply can be ensured while reducing the impact on the settling of solid waste.

[0049] Specifically, each of the aforementioned breeding pens 4 is also equipped with a feeder 19. The feeder 19 is a solar-powered fully automatic feeder 19.

[0050] Specifically, the side wall of the sludge collection bin 6 is provided with a drain outlet, the drain outlet is connected to a drain pipe 61, the drain pipe 61 is provided with a control valve 62, and the distance between the drain outlet and the bottom of the sludge collection bin 6 is 0.5m.

[0051] Specifically, each floating plate assembly includes a first floating plate 81 and several rows of floating units 82. Two first floating plates 81 are installed within each sedimentation tank 5. The floating units 82 are located on the outside of the steel frame 2. Each row of floating units 82 consists of several second floating plates 821 connected end-to-end. The first and second floating plates 81 are 1m x 2m in length and width, and each first and second floating plate 81 has 50 planting holes. During planting, a planting cup is fixed in each planting hole, and hydroponic rice is planted in the planting cup. Four rows of floating units 82 are laid on each of the left and right sides of the steel frame 2, each row consisting of 40 second floating plates 821 connected end-to-end along the long side. One row is laid on each of the left and right sides of the steel bridge 3, each row consisting of 14 floating plates connected end-to-end along the long side.

[0052] One specific application of this utility model is: When pond 1 is drained, a steel frame 2 and a steel bridge 3 are constructed. The aquaculture chamber 4, sedimentation chamber 5, Roots blower 17, and feeder 19 are assembled on the steel frame 2. The sludge suction and discharge components are also assembled. After the aquaculture cage 15 is installed in the aquaculture chamber 4, the aeration pipe 18 connected to the Roots blower 17 is suspended in the middle of the aquaculture cage 15.

[0053] After all the facilities are assembled, water is injected into pond 1. The water level should be controlled to slightly overflow the first water exchange port 41 of aquaculture tank 4 and the second water exchange port 51 of sedimentation tank 5. The first and second water pressure balance control valves 14 are opened when water is injected and closed after water injection is completed.

[0054] Taking farmed chub as an example, the stocking density of chub in each of the four net cages in each culture tank is 800 fish / m². 3 In addition to the main fish species, the chub, the omnivorous smelt is also raised in the pond at a density of 40 fish / m². 3 The bryophytes feed on algae, uneaten food, and feces adhering to the net cages, keeping the cages clean and permeable, which facilitates the full settling of solid waste.

[0055] Feeder 19 provides feed 3-4 times a day at fixed times and in fixed quantities. First sludge pump 10 sludges every 4 hours for 3 minutes each time, and second sludge pump 13 sludges once a day for 10 minutes. Solid waste extracted from sedimentation tank 5 enters sludge collection tank 6; the drain is closed during collection. After collection, the solid waste settles at the bottom of sludge collection tank 6. Once completely settled, the drain is opened, and the upper layer of clear water flows back into the purification soil tank. The solid waste settled at the bottom of sludge collection tank 6 is removed every 10 days and can be recycled as fertilizer for flowers.

[0056] This utility model is based on an ecological aquaculture system and improves the solid waste removal facilities. It can remove solid waste generated during the aquaculture process in a timely and sufficient manner, reduce the pressure of aquaculture wastewater on the environment, significantly improve the stability of the aquaculture environment and aquaculture efficiency, and effectively solve the problem of aquaculture wastewater discharge treatment in pond 1. The aquaculture tank 4 and sedimentation tank 5 adopt square canvas pools, which improves the space utilization rate and reduces the manufacturing cost. At the same time, through the planting of floating hydroponic rice, the in-situ purification efficiency of aquaculture wastewater and the planting and breeding benefits are effectively improved.

[0057] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
