Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment, and relates to a low-energy-consumption circulating water aquaculture device. BACKGROUND

[0002] With the increasing demand for aquatic products, the scale of aquaculture is expanding. However, in traditional aquaculture, water pollution is a very prominent problem. During the cultivation process, the excrement of aquatic animals, residual feed and the like continuously accumulate in the cultivation water. These pollutants not only deteriorate the water quality, leading to eutrophication of the water body, but also breed a large number of harmful bacteria and pathogens, seriously threatening the health of aquatic animals. For example, in high-density ponds, excessive ammonia nitrogen, nitrite and other harmful substances can cause the immune system of aquatic animals to decline, making them susceptible to various diseases such as gill rot, enteritis and the like, resulting in a large number of aquatic animal deaths and causing huge economic losses to the breeders. At the same time, the deterioration of water quality also affects the growth rate and quality of aquatic animals. In a poor water quality environment, aquatic animals are in a state of stress, their growth is inhibited, and the meat quality is also poor. Taking fish as an example, fish grown in polluted water have increased levels of fishy substances in their muscles, and their taste and nutritional value are reduced, making it difficult to meet the market demand for high-quality aquatic products.

[0003] In addition, the traditional cultivation method also wastes a lot of water resources. In order to maintain a certain water quality, breeders often need to frequently change the water. A large amount of fresh water is introduced into the cultivation pond, while the water containing pollutants is directly discharged into the environment. This not only causes a great waste of water resources, but also may pollute the surrounding ecological environment. In some areas where water resources are relatively scarce, this kind of cultivation method that wastes water resources is unsustainable.

[0004] Moreover, with the continuous expansion of the scale of aquaculture, the cultivation space becomes increasingly limited. In order to achieve efficient cultivation in a limited space, it is necessary to solve the problem of water purification. Traditional simple filtration equipment has low filtration efficiency and is difficult to effectively remove small particles and dissolved pollutants in water, and cannot fundamentally improve the water quality, which cannot meet the needs of large-scale and high-density cultivation. For example, physical filtration may only intercept larger particles of impurities, but it is powerless against dissolved ammonia nitrogen and nitrite; while biological filtration can decompose part of the organic matter, but it is slow in processing high-concentration pollutants, and biological filtration relies on specific microbial communities to decompose organic matter and transform harmful substances, and it is difficult to precisely control the microbial communities in the biological filtration system to ensure the stability and effectiveness of the biological filtration.

[0005] Therefore, it is an urgent technical requirement in the aquaculture industry to develop a circulating cultivation device that can quickly and efficiently remove various pollutants in water, maintain water quality, reduce water resource waste and save energy.

[0006] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely describing the technical scheme of the present application and facilitating the understanding of the skilled in the art. The above technical scheme cannot be considered as known to the skilled in the art only because it is described in the background section of the present application. SUMMARY

[0084] In order to solve the problems of water pollution and water resource waste in traditional aquaculture in the prior art, the present application provides a low-energy-consumption circulating aquaculture device which integrates fecal separation, biochemical filtration, physical filtration and fluidized filtration, realizes rapid and efficient removal of various pollutants in water in a limited space, maintains water quality and reduces water resource waste.

[0085] In one specific embodiment of the low-energy-consumption circulating aquaculture device, as Figures 1-21As shown, the low-energy consumption recirculating aquaculture device comprises a culture pond with a fecal separation structure, a filter pond for treating the culture pond inflow, and a biological fluidized filter pond 30 for treating the filter pond inflow and returning to the culture pond; the culture pond comprises a culture pond body 10, the bottom of which is formed with a first sewage outlet 111; the filter pond comprises a filter pond body 20, a plurality of suspended biochemical filter bags 21 for treating the inflow, and a support filter plate 22 provided at the inflow of the filter pond body 20, the biochemical filter bag 21 comprises a biochemical filter bag body for physical filtration and a biochemical filter material filled in the biochemical filter bag body, and the biochemical filter bag 21 is suspended at the corresponding position of the filter hole 221 of the support filter plate 22. The low-energy consumption recirculating aquaculture device sequentially filters the water in the culture pond body 10 twice through the filter pond and the biological fluidized filter pond 30 and returns to the culture pond body 10; the inflow in the culture pond body 10 is first subjected to physical and biochemical filtration by the biochemical filter bag 21, thereby ensuring the filtration efficiency and water purification effect; and the culture contaminants deposited in the culture pond body 10 are discharged through the first sewage outlet 111. The low-energy consumption recirculating aquaculture device realizes efficient removal of various pollutants in the water body, maintains water quality, and reduces water resource waste.

[0086] In this application, the culture pond is used for aquaculture and / or ornamental aquatic organism breeding.

[0087] In one specific embodiment, the suspended biochemical filter bag 21 is suspended in the filter pond body 20 for biochemical and physical filtration treatment of the inflow.

[0088] The culture pond body 10, the filter pond body 20, and the biological fluidized filter pond are open-top tank bodies. In one specific embodiment, the inflow is from the top of the filter pond body 20, and after falling based on gravity, the inflow is filtered by the support filter plate 22 and then subjected to biochemical and physical filtration treatment by the biochemical filter bag 21.

[0089] It should be noted that the material, size, and shape of the culture pond body 10, the filter pond body 20, and the biological fluidized filter pond can be adjusted according to the actual breeding site needs, the inflow rate, and the filtration rate, as long as the filtration rate is greater than or equal to the inflow rate and is suitable for the breeding site needs. For example, the culture pond body 10, the filter pond body 20, and the biological fluidized filter pond can be one or more of a cubic tank body, a cylindrical tank body, a circular truncated cone tank body, and an elliptical tank body. For example, the culture pond body 10, the filter pond body 20, and the biological fluidized filter pond can be a cubic tank body, a cylindrical tank body, a circular truncated cone tank body, and an elliptical tank body. Figures 1-21In a specific embodiment, the culture tank body 10, the filter tank body 20 and the biological fluidized filter tank are open-top cylindrical tanks, which are easier to evenly disperse pressure and reduce stress concentration than square tanks. The materials of the culture tank body 10, the filter tank body 20 and the biological fluidized filter tank can be cement, metal, plastic or ceramic. The volume of the culture tank body 10 is 4 times the sum of the volumes of the filter tank body 20 and the biological fluidized filter tank. This volume ratio ensures the filtering efficiency while minimizing the space occupied by the filtering device and effectively utilizing the space resources.

[0090] In a specific embodiment, as shown in Figures 1-6 In a specific embodiment, as shown in

[0091] It should be noted that the size and form of the pressure-resistant ring can be arbitrarily selected according to the actual tank body periphery and the use state, as long as it can guarantee the safety and stability of the tank body without deformation under the condition of being filled with water.

[0092] In a more specific embodiment, as shown in Figures 1-6 In a more specific embodiment, as shown in

[0093] In a more specific embodiment, as shown in Figures 1-6 In a more specific embodiment, as shown in

[0094] In a more specific embodiment, as shown in Figures 14-17 In a more specific embodiment, as shown in

[0095] In a more specific embodiment, as shown in Figures 1-6 In a more specific embodiment, as shown in

[0096] In a specific embodiment, as shown in Figures 1-6 In a specific embodiment, as shown in

[0097] In a more specific embodiment, as shown in Figures 1-6As shown, the culture pond body 10 is further formed with a conical or frustoconical first sediment enrichment part 11 at the first pollution outlet 111, and the slope of the first sediment enrichment part 11 is greater than the slope of other parts of the bottom surface of the culture pond body 10. The pollutants deposited in the culture pond body 10 are more likely to gather at the first pollution outlet 111 of the first sediment enrichment part 11, and the deposited pollutants can be efficiently discharged.

[0098] In the present application, the deposited pollutants include excrement, secretions, and feed residues of the cultured organisms.

[0099] In a specific embodiment, as shown in the drawings, Figures 1-13 As shown, the culture pond further comprises a conveying assembly for conveying water in the culture pond body 10 to the filter pond body 20.

[0100] In a more specific embodiment, as shown in the drawings, Figures 1-13 The conveying assembly comprises a shower pipe 12 and a plurality of water source drives 13, the shower pipe 12 is in fluid communication with the water source drives 13, and the shower pipe 12 is formed with a plurality of shower holes 121 at the corresponding position of the filter pond body 20. The water source drives 13 drive the water in the culture pond body 10 to be conveyed to the filter pond body 20 through the shower pipe 12.

[0101] In the present application, the shower pipe refers to the water outlet pipe of the culture pond to be replaced. The reason why it is called a shower pipe is that a plurality of arrayed water outlet holes are formed on the water outlet pipe to form a spraying or showering element similar to a "shower". Any water outlet pipe that can meet the functional requirements belongs to the technical solution claimed in the present application, and its specific shape or structure can be set according to the specific subsequent processing end.

[0102] In a more specific embodiment, as shown in the drawings, Figures 1-13 The first end of the shower pipe 12 is composed of a plurality of water outlet pipes 122, and any water outlet pipe 122 is in fluid communication with a water source drive 13. The water outlet pipe 122 corresponds to the water source drive 13 one by one, so that the stoppage of work of one group of water source drives 13 does not affect the water flow output of the whole shower pipe 12.

[0103] In a more specific embodiment, as shown in the drawings, Figures 1-10 The water source drive 13 is selected from a water pump.

[0104] It should be noted that the number of water outlet pipes 122 and water source drives 13 is consistent, and can be arbitrarily selected according to actual needs, such as the actual output water flow rate, the filtering rate of the external filtering device, and the size of the culture pond sediment body 10. For example, the number of water outlet pipes 122 and water source drives 13 can be 1, 2, 3, 4, 5, or 6. Figures 1-21In a specific embodiment, the water outlet pipe 122 and the number of water source drives 13 are two, and the two water source drives 13 are respectively a main water pump and an emergency water pump, which are respectively in fluid communication with a water outlet pipe 122. The main pump is used for water driving in normal work, and the emergency pump operates when the main pump is paralyzed, so as to pump water normally, so as to avoid causing huge economic losses. In a more specific embodiment, as shown in Figures 1-8 The rain pipe 12 tail end is provided with a rain department formed with a rain hole 121, the rain department is formed above the support filter plate 22, and the shape of the rain department is selected from one or more of "I", "Y", "X", and "rice" shapes. In a specific embodiment as shown in Figures 1-8 The shape of the rain department is "X". The "X" shaped rain pipe 12 makes the water in the culture pond body 10 flow into the filter pond body 20 more evenly and dispersedly through the rain hole 121 in the rain department, increases the oxygen content in the water, and makes the biochemical filtration in the filter pond more evenly and effectively.

[0105] In a specific embodiment, as shown in Figures 1-13 The support member 14 is fixed to the bottom of the culture pond sediment body 10. The support member 14 supports and limits the water source drive 13, so that the water source drive 13 is limited to a certain height, so that it does not output the pollutants deposited on the bottom, but only outputs the aquaculture sewage after preliminary sedimentation.

[0106] In a further embodiment, as shown in Figures 1-13 The support member 14 is formed with a containing bin 141 for containing and supporting the water source drive 13, the containing bin 141 includes a top cover 1412 and a side wall 1413, and the containing bin 141 is formed with a plurality of water inlet holes 1411. The containing bin 141 limits the water source drive 13 to a certain position and height, so as to facilitate the stable output of the water after preliminary sedimentation to the filter pond body 20, and the water inlet hole 1411 makes the water entering the water source drive 13 more evenly and preliminarily physically filters the water entering the water source drive 13.

[0107] In a further embodiment, as shown in Figures 1-13 The water inlet hole 1411 is formed on the top cover 1412 and the side wall 1413 of the containing bin 141, the top cover 1412 and the side wall 1413 are sealingly and fixedly connected, and the top cover 1412 is formed with a fourth through hole 1415 for the rain pipe 12 to pass through.

[0108] In a further embodiment, as shown in Figures 1-13 The containing bin 141 covers the first sediment enrichment part 11, and the bottom thereof is formed with a filter part for the deposited pollutants to pass through.

[0109] In a further embodiment, as shown in Figures 1-13 The breeding tank further comprises a filter cover 142, which is arranged above the first sediment enrichment part 11 and is used for passing the deposited pollutants. The filter cover 142 is formed with a first through hole 1421. The first through hole 1421 preliminarily screens the deposited pollutants before they are gathered in the first sediment enrichment part 11, so as to block the pollutants with too large particles and avoid the first drain 111 from being blocked.

[0110] In a further embodiment, as shown in Figures 1-13 The containing bin 141 is arranged above the filter cover 142. Arranging the containing bin 141 above the filter cover 142 makes the filtering position of the deposited pollutants lower than the position of the water source drive 13 in the containing bin 141, so as to improve the draining efficiency and the subsequent filtering efficiency of the output sewage.

[0111] It should be noted that the positions and connection relationship of the containing bin 141 and the filter cover 142 in the breeding tank body 10 can be arbitrarily selected according to actual needs, as long as the containing bin 141 is arranged above the filter cover 142.

[0112] In a specific embodiment, as shown in Figures 1-13 The containing bin 141 is arranged above the filter cover 142 and the connection part is sealed. This is more space-saving in the breeding tank body 10 and improves the utilization rate.

[0113] In a more specific embodiment, as shown in Figures 1-11 The containing bin 141 is arranged above the filter cover 142 and the connection part is sealed. This is more space-saving in the breeding tank body 10 and improves the utilization rate.

[0114] In a specific embodiment, as shown in Figures 1-6 The breeding tank body 10 is downwardly protruded at the bottom to form a breeding tank support frame 15. The breeding tank support frame 15 makes the breeding tank body 10 more stable and forms a space for the sewage pipeline to smoothly flow out or be replaced.

[0115] It should be noted that the size and shape of the breeding tank support frame 15 can be arbitrarily selected according to actual needs, as long as the breeding tank body 10 is stably supported and / or filled with water. For example, the breeding tank support frame 15 can be one or more of a plurality of cylindrical support columns, a plurality of cubic support columns and a support ring.

[0116] In a specific embodiment, as shown inFigures 1-6 In the specific embodiment shown, the culture pond support frame 15 is in the shape of a concentric ring. The concentric ring-shaped culture pond support frame 15 evenly disperses the weight of the culture pond body 10 in the concentric ring, reduces the pressure of the culture pond body 10 on the ground, and facilitates stable placement of the culture pond body 10.

[0117] In a specific embodiment, as shown in Figures 1-6 The first sewage outlet 111 circumscribes the first sewage pipe 16.

[0137] It should be noted that the size and filter aperture of the biochemical filter bag body can be arbitrarily selected according to actual needs, as long as the target filtering effect and the type of aquaculture wastewater are met.

[0138] In a specific embodiment, the biochemical filter bag body is selected from Maopu Mao Caodi Mo bag. The biochemical filter bag 21 performs preliminary physical filtration and biochemical filtration on the inflow of the aquaculture pond. The residual pollutants are physically intercepted by the biochemical filter bag body and biochemically filtered by the biochemical filter material.

[0139] In a specific embodiment, as shown in Figures 1-6 The fluidized bed filler 31 is filled in the biological fluidized filter tank 30. Compared with the traditional static filter material, the fluidized bed filler 31 with a hollow structure is lighter and easier to replace. During the filtering process, the impurities deposited on the surface are removed by the collision between the fluidized bed fillers 60 driven by the water flow, reducing the frequency of filter replacement and cleaning, and reducing the cost of filter replacement and maintenance.

[0140] In a more specific embodiment, as shown in Figures 1-6 The fluidized bed filler 31 is selected from one or more of K1 filler, K2 filler, K3 filler, K4 filler, K5 filler, QY-PE02 filler, QY-PE03 filler, QY-PE04 filler, QY-PE08 filler, Maopu Youjinku 7PLUS filler, Maopu Youjinku 5S filler.

The filter groove 32 is arranged between the water outlet 33 and the fluidized bed filler 31. The filter groove 32 separates the fluidized bed filler 31 from the water outlet 33, so that the water filtered by the fluidized bed filler 31 can be output from the water outlet 33 at a stable speed.

[0142] In a further embodiment, as shown in Figures 1-6As shown in Figures 20 and 21, the biological fluidized bed filter 30 also includes an aeration pipe 34, which is located above the filter tank 32. The aeration pipe 34 drives the fluidized bed packing material 31 in the water to move, so that the fluidized bed packing material 31 has more sufficient contact with the water and is oxygenated, promoting the growth of bacteria on the surface of the fluidized bed packing material 31 and improving the filtration efficiency of the device.

The highest point of the second water guide pipe 35 is lower than that of the biological fluidized bed filtration tank 30. Because the highest point of the second water guide pipe 35 is lower than that of the biological fluidized bed filtration tank 30, a water pressure difference is generated between the water in the second water guide pipe 35 and the water in the biological fluidized bed filtration tank 30. Under the action of gravity and water pressure, the water in the biological fluidized bed filtration tank 30 continuously flows into the second water guide pipe 35 and further into the aquaculture tank body 10.

[0144] It should be noted that the recirculation method of the filtered water in the biological fluidized bed filtration tank 30 back to the aquaculture tank body 10 can be adjusted according to actual aquaculture and economic needs, as long as it can ensure the recirculation of the filtered water in the biological fluidized bed filtration tank 30 back to the aquaculture tank body 10. The recirculation method can be one or more of pressure recirculation, power-driven recirculation, and manual recirculation. Pressure recirculation refers to creating a water pressure difference between the water in the second water guide pipe 35 and the water in the biological fluidized bed filtration tank 30. Under the action of gravity and water pressure, the water in the biological fluidized bed filtration tank 30 continuously flows into the second water guide pipe 35 and further into the aquaculture tank body 10. Power-driven recirculation refers to using a motor, such as a water pump, to drive the water source back to the aquaculture tank body 10.

[0145] In a further embodiment, such as Figures 1-6 As shown in Figures 20 and 21, the second water guide pipe 35 is also equipped with a germicidal lamp and has a fourth through hole for the germicidal lamp to enter and a sealing cover 351 for sealing the fourth through hole. The germicidal lamp includes an ultraviolet lamp. The germicidal lamp performs final sterilization and disinfection on the water flowing into the aquaculture pond body 10, removing bacteria and viruses that cannot be removed by biochemical and physical filtration, and further improving water quality.

[0146] In a like Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 Figures 1-6 FiguresThe specific operation method of the low-energy consumption circulating water aquaculture device includes the following steps: water in the aquaculture pool body 10 enters the containing bin 141 through the water inlet hole 1411 under the action of the water source drive 13, and then enters the rain pipe 121 through the water outlet pipe 122, and is further delivered to the upper side of the support filter plate 22; the water in the aquaculture pool body 10 enters the biochemical filter bag 21 through the filter hole 221 in the support filter plate 22, and then flows into the filter pool body 20 through biochemical and physical filtration of the biochemical filter bag 21 and the filled biochemical material, and accumulates and deposits pollutants; after the accumulated water after deposition overflows the top of the filter pool body 20, it enters the overflow groove 23, and is delivered to the biological fluidized filter pool 30 through the first water guide pipe 231; the fluidized bed filler 31 in the biological fluidized filter pool 30 performs fluidized movement above the filter tank 32 under the action of the aeration pipe 34, and further performs fluidized filtration on the water; after the fluidized filtration, the water flows back to the aquaculture pool body 10 through the sterilization of the germicidal lamp in the second water guide pipe 35 under the action of the water pressure difference, and the cycle is completed; when the pollutants deposited at the bottom of the aquaculture pool body 10 and the filter pool body 20 reach a certain degree, the electromagnetic valve is opened, so that the deposited pollutants are discharged through the first and second sewage pipes 16 and 24.

[0147] The low-energy consumption circulating water aquaculture device integrates fecal separation, biochemical filtration, physical filtration and fluidized filtration, and only needs to provide a water source drive, so that various pollutants in the water body can be quickly and efficiently removed in a limited space, the water quality is maintained, and water resource waste is reduced; the low-energy consumption circulating water aquaculture device only needs to rely on a group of water source drives to realize the overall circulation and water flow, thereby reducing energy waste; the suspended biochemical filter bag quickly and efficiently performs biochemical and physical filtration on the water in the aquaculture pool, thereby further improving the purification efficiency of the entire low-energy consumption circulating water aquaculture device.
