Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to an industrialized fishpond aquaculture system. Background Art

[0002] Currently, aquatic products such as fish, shrimps, and crabs are generally cultured in natural waters or fishponds, adopting a static closed aquaculture method, which belongs to the traditional extensive aquaculture mode and is a production method relying on the weather. With the development of technology and the progress of the aquaculture industry, the traditional fishpond aquaculture mode can no longer meet the needs of the modern market, mainly reflected in several aspects such as low production efficiency, serious water pollution, and high aquaculture costs.

[0003] The main reason for the low production efficiency is that the fishpond aquaculture output has approached the ceiling. Facing limited water resources, the space to increase output by expanding the aquaculture area is getting smaller and smaller; the sizes of aquatic products are different, and it is difficult to screen them in large - area fishponds, so it is impossible to ensure fishing and sales at any time; generally, only one type of aquatic product can be cultured in one fishpond, with a single variety, which is not conducive to increasing production and income. The main reason for the serious water pollution lies in the discharge of aquaculture tail water, the abuse of fish drugs, etc., and it is difficult to regulate the water quality in large - area fishponds. The main reason for the high aquaculture cost is that the complex aquaculture environment makes aquatic products prone to diseases, and the cost of animal protection is high; the cost of fishing and pond cleaning of aquatic products is relatively high; a large number of equipment are required to maintain balanced oxygen supply as much as possible, with high energy consumption and high cost.

[0004] Therefore, there is an urgent need to provide a new aquaculture system to improve production efficiency and water quality and reduce aquaculture costs. Summary of the Invention

[0005] To solve the above - mentioned defects in the prior art, the purpose of the present invention is to provide an industrialized fishpond aquaculture system, which can improve production efficiency and water quality, reduce aquaculture costs, and meet the market's demand for high - quality aquatic products.

[0007] An aquaculture unit for aquaculture and separating circulating water and feces;

[0008] An ecological purification unit for purifying circulating water and increasing oxygen. The ecological purification unit is connected to the aquaculture unit to form a water circulation loop, so as to discharge the circulating water separated by the aquaculture unit to the ecological purification unit for purification and oxygenation and then return it to the aquaculture unit;

[0009] A precipitation unit for precipitating and concentrating feces. The precipitation unit is connected to the aquaculture unit to discharge the feces separated by the aquaculture unit to the precipitation unit for precipitation and concentration;

[0010] A resource utilization unit for resource utilization of manure sewage, the resource utilization unit is connected to the precipitation unit to discharge the manure sewage precipitated and concentrated by the precipitation unit to the resource utilization unit for resource utilization;

[0011] Both the aquaculture unit and the ecological purification unit are located in the water area, and the precipitation unit is located in the water area or outside the water area.

[0014] As a preferred embodiment, in the present invention, the precipitation unit is connected to the ecological purification unit to purify the circulating water after the manure sewage is precipitated and concentrated through the ecological purification unit.

[0015] As a preferred embodiment, in the present invention, the resource utilization unit includes an anaerobic fermentation device and / or an ecological ditch and / or a biological filter and / or a fertilizer production device and / or a biological decomposition device.

[0020] As a preferred embodiment, in the present invention, the water area includes a pond water area, a river water area, a lake water area or a reservoir water area.

[0021] The factory aquaculture system in the fishpond provided by the present invention has the following technical effects:

[0022] The water circulation loop formed by the aquaculture unit and the ecological purification unit can discharge the circulating water with low water quality and low oxygen content separated by the aquaculture unit to the ecological purification unit, so as to utilize the ecological purification unit to purify and oxygenate the circulating water to obtain return water with high water quality and high oxygen content, and then return it to the aquaculture unit for aquaculture; the manure treatment unit composed of the aquaculture unit, the sedimentation unit and the resource utilization unit can realize the separation, sedimentation and resource utilization treatment of manure.

Detailed implementation manners

[0033] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] Refer to Figure 4 , the present invention provides a factory aquaculture system for fish ponds, including a breeding unit 1 for aquaculture and separating circulating water and manure, an ecological purification unit 2 for purifying circulating water and increasing oxygen, a sedimentation unit 3 for sedimenting and concentrating manure, and a resource utilization unit 4 for resource treatment of manure. The breeding unit 1 and the ecological purification unit 2 are both arranged in the water area 100, the sedimentation unit 3 is arranged in the water area 100, or the sedimentation unit 3 is arranged outside the water area 100 such as on the shore base.

[0037] Combined with Figures 1-3 , the breeding unit 1 includes at least one breeding pond 11. The number of breeding ponds 11 is one, two or more, and its quantity is determined according to the area of the water area 100 and the breeding requirements. The breeding pond 11 is arranged in the water area 100, and can draw water from the water area 100 for aquaculture, and feed can be put into the breeding pond 11 during the breeding process.

[0038] The residual bait feed and excreted feces in aquaculture are collectively referred to as fecal sewage. The accumulation of fecal sewage in the aquaculture pond 11 will pollute the water quality. The oxygen consumption during the aquaculture process leads to a decrease in the oxygen content in the aquaculture pond 11, thus deteriorating the aquaculture environment. Therefore, the aquaculture pond 11 has the function of separating fecal sewage and circulating water to facilitate the separate treatment of fecal sewage and circulating water with low water quality and low oxygen content after separation.

[0039] The ecological purification unit 2 is connected to the aquaculture unit 1 to form a water circulation loop, so as to discharge the circulating water separated by the aquaculture unit 1 to the ecological purification unit 2 for purification and oxygenation and then return it to the aquaculture unit 1. The ecological purification unit 2 can be arranged in the entire water area 100 around the aquaculture unit 1 for purifying water quality and oxygenation. The circulating water outlet of the aquaculture unit 1 is connected to the ecological purification unit 2 through a circulating water pipe 12 to discharge the circulating water with low water quality and low oxygen content into the ecological purification unit 2 for purification and oxygenation. A return water pipe 14 is also connected between the ecological purification unit 2 and the aquaculture unit 1 to facilitate the return of the high-quality and high-oxygen-content return water purified and oxygenated by the ecological purification unit 2 to the aquaculture unit 1. In this cycle, a good aquaculture environment for aquatic products is achieved through the aquaculture method of circulating aquaculture.

[0040] The precipitation unit 3 is connected to the aquaculture unit 1 to discharge the fecal sewage separated by the aquaculture unit 1 to the precipitation unit 3 for precipitation and concentration. The aquaculture unit 1 is connected to the precipitation unit 3 through a fecal sewage pipe 13 to discharge the fecal sewage separated by the aquaculture unit 1 to the precipitation unit 3 for precipitation and concentration. The precipitation unit 3 includes at least one sedimentation tank 31, and the number of sedimentation tanks 31 is determined according to the precipitation and concentration requirements.

[0041] The resource utilization unit 4 is connected to the precipitation unit 3 to discharge the fecal sewage precipitated and concentrated by the precipitation unit 3 to the resource utilization unit 4 for resource utilization treatment. The precipitation unit 3 can be connected to the resource utilization unit 4 through a fecal sewage discharge pipe 32 to carry out resource utilization treatment on the precipitated and concentrated fecal sewage through the resource utilization unit 4, thus avoiding the impact of fecal sewage discharge on the environment.

[0042] Based on this, the water circulation loop composed of the aquaculture unit 1 and the ecological purification unit 2 can discharge the circulating water with low water quality and low oxygen content separated by the aquaculture unit 1 to the ecological purification unit 2 to purify and oxygenate the circulating water by using the ecological purification unit 2 to obtain high-quality and high-oxygen-content return water, and then return it to the aquaculture unit 1 for aquaculture; the fecal sewage treatment unit composed of the aquaculture unit 1, the precipitation unit 3 and the resource utilization unit 4 can realize the separation, precipitation and resource utilization treatment of fecal sewage. In this way, the combination of the water circulation loop and the fecal sewage resource utilization treatment can realize the factoryization of fish ponds, improve the production efficiency and water quality of aquaculture, and reduce the aquaculture cost. Specifically:

[0043] In terms of water quality, the setting of the water circulation loop can achieve water quality purification and recirculating aquaculture within the water area 100. It can not only achieve water quality regulation on its own, but also realize zero discharge of aquaculture water without pond cleaning. At the same time, fecal sewage will not be discharged into the environment, effectively avoiding the pollution of aquaculture water and the environment. In addition, the self-purification and oxygenation of the aquaculture water inside provides a good aquaculture environment for aquatic products, eliminating the need for excessive use of fish drugs and further ensuring the cleanliness and hygiene of the water quality.

[0044] In terms of aquaculture cost, a good aquaculture environment can ensure the healthy aquaculture of aquatic products, significantly reducing the cost of animal health protection; recirculating aquaculture can regulate water quality and oxygenate on its own to maintain balanced oxygen supply, eliminating the need for pond cleaning and significantly reducing equipment costs; the aquaculture is carried out in aquaculture unit 1 instead of the entire water area 100, facilitating fishing and helping to reduce fishing costs.

[0045] In terms of production efficiency, a good aquaculture environment can achieve high-density and low-carbon aquaculture of aquatic products, which is conducive to improving the proximity of the growth specifications of aquatic products, facilitating fishing and sales. Moreover, the setting of aquaculture unit 1 in the water area 100 enables the simultaneous aquaculture of multiple varieties of aquatic products, contributing to increased production and income.

[0046] Combined Figure 5 , the ecological purification unit 2 includes a waterweed cultivation area and a microorganism cultivation area. Several waterweeds are planted in the waterweed cultivation area, and several microorganisms are cultivated in the microorganism cultivation area. The waterweed cultivation area and the microorganism cultivation area can be set to overlap, intersect, or be separated. Waterweeds, microorganisms, algae, etc. can be cultivated in any area of the water area outside aquaculture unit 1. They can purify the suspended matter in the circulating water, reduce the ammonia nitrogen content, and increase the oxygen content through photosynthesis, so that the return water with high water quality and high oxygen content can be refluxed to aquaculture unit 1 to ensure a good aquaculture environment.

[0047] The ecological purification unit 2 also includes an aquaculture area, which is set in the waterweed cultivation area. The aquaculture area can appropriately breed aquatic products such as fish and shrimp to make full use of the water body with high water quality and high oxygen content in the ecological purification unit 2, and can also increase the variety of aquatic products to achieve increased production and income.

[0048] It should be noted that the setting of the aquaculture area needs to ensure that it does not affect the purification and oxygenation ability of waterweeds, microorganisms, etc. on the circulating water, so as not to affect the normal aquaculture in aquaculture unit 1. Based on this, aquaculture unit 1 can also be equipped with an oxygenation device and a dissolved oxygen detection device to detect the oxygen content in aquaculture unit 1 in real time, and use the oxygenation device to increase oxygen when the oxygenation ability of the ecological purification unit 2 is insufficient, so as to ensure sufficient oxygen content in aquaculture unit 1. At the same time, aquaculture unit 1 can also be equipped with a pH detection device and a temperature detection device to ensure the appropriate pH and temperature of the aquaculture water, thus ensuring a good aquaculture environment.

[0049] The aquaculture system further includes an ecological polyculture unit, which is arranged on the return water path between the aquaculture unit 1 and the ecological purification unit 2. Aquatic products are cultured in the ecological polyculture unit. The ecological purification unit 2 can be distributed around the aquaculture unit 1 or set at a distance from the aquaculture unit 1. Thus, an ecological polyculture unit can be set between the ecological purification unit 2 and the aquaculture unit 1 to make full use of the return water after purification and oxygenation to increase the types and quantities of aquaculture, and further achieve increased production and income.

[0050] Moreover, shrimps, crabs and filter-feeding fish are cultured in the ecological polyculture unit to purify the circulating water and improve the aquaculture benefits. Filter-feeding aquatic products such as filter-feeding fish include silver carp, bighead carp, etc., which feed on planktonic animals and plants and can further purify the water quality, so as to greatly improve the quality of the return water.

[0051] On this basis, the sedimentation unit 3 is connected to the ecological purification unit 2 to purify the circulating water after the fecal sewage is sedimented and concentrated through the ecological purification unit 2. After the sedimentation unit 3 sedimentes and concentrates the fecal sewage, the separated circulating water can be discharged to the ecological purification unit 2 through the circulating water discharge pipe 33 for purification and oxygenation, and then flows back to the aquaculture unit 1 for recycling. This enables the sedimentation unit 3 not to perform resource treatment on the circulating water after the fecal sewage is sedimented and concentrated, which is beneficial to reducing the aquaculture cost.

[0052] The aquaculture system further includes a sewage collection and transfer unit 5, which is arranged between the aquaculture unit 1 and the sedimentation unit 3. The fecal sewage separated from the aquaculture unit 1 has a high water content and is first discharged into the sewage collection and transfer unit 5 for preliminary concentration, so as to more efficiently and centrally send the fecal sewage into the sedimentation unit 3, thereby accelerating the sedimentation and concentration of the fecal sewage by the sedimentation unit 3 and reducing the energy consumption.

[0053] The fecal sewage after sedimentation and concentration by the sedimentation unit 3 is subjected to resource treatment. The resource unit 4 includes an anaerobic fermentation device 41 and / or an ecological ditch 42 and / or a biological filter tank and / or a fertilizer production device and / or a biological decomposition device.

[0054] The sedimentation unit 3 is connected to the ecological ditch 42 and / or the biological filter tank. Aquatic plants, aquatic products and microorganisms are cultivated in the ecological ditch 42 and the biological filter tank to purify the tail water. If there is more fecal sewage, it can be discharged to the anaerobic fermentation device 41, and anaerobic microorganisms are used to decompose organic substances to produce biogas, which can be used for power generation or directly as an energy source. The remaining biogas slurry and biogas residue can be further processed into organic fertilizer. If there is less fecal sewage, it can be directly discharged into the ecological ditch 42. By cultivating aquatic plants, aquatic products, microorganisms, etc. in the ecological ditch 42, the nutrient substances in the fecal sewage can be fully utilized, so that by-products such as aquatic plants and aquatic products can be produced and sold to achieve increased production and income. Moreover, by consuming the nutrient substances, the contents of ammonia nitrogen, nitrite, etc. in the ecological ditch 42 can be reduced to achieve the purpose of purification and avoid environmental pollution.

[0055] Of course, the manure and sewage precipitated and concentrated by the precipitation unit 3 can also be used in the following aspects:

[0056] The manure and sewage precipitated and concentrated by the precipitation unit 3 are mixed with conditioning agents such as straw and wood chips to adjust the carbon-nitrogen ratio and moisture content, and then the mixture is piled into strips or heaps and regularly turned over to ensure sufficient oxygen, so that aerobic microorganisms can be used to decompose organic substances to form organic fertilizers rich in organic matter, nitrogen, phosphorus, potassium and other nutrient elements for agricultural planting.

[0057] The manure and sewage precipitated and concentrated in the precipitation unit 3 can be introduced into a biological filter. Microorganisms and plant roots in the biological filter absorb and decompose the nutrients in the manure and sewage to obtain purified water for recycling.

[0058] The manure and sewage precipitated and concentrated by the precipitation unit 3 can be mixed with appropriate amounts of humus soil, straw and other conditioning agents to form an environment suitable for the growth of insects. The mixture is placed in an insect composting box, so that insects can be used to decompose the manure and sewage to generate insect feed rich in organic matter.

[0059] The manure and sewage precipitated and concentrated by the precipitation unit 3 are introduced into an algae cultivation pond to utilize algae to absorb nutrients such as nitrogen and phosphorus for photosynthesis, which can not only reduce the pollution of manure sewage to the environment, but also harvest the algae as high-protein feed or raw materials for bioenergy.

[0060] Two or more of the above-mentioned resource treatment methods can be used simultaneously to make full use of manure sewage for resource utilization, which not only protects the environment, but also can be used for the production and sales of by-products to increase income.

[0061] It can be seen from this that the present invention provides a high-density low-carbon cycle aquaculture system for industrial aquaculture in the water area 100. By placing a high-density low-carbon aquaculture unit 1 in the water area 100, realizing plug-flow high-density aquaculture in the aquaculture unit 1, automatically collecting manure and sewage to achieve sewage cleaning and diversion, realizing the water circulation between the aquaculture unit 1 and the ecological purification unit 2 through a circulation loop, and cultivating aquatic plants, aquatic products, etc. in the ecological purification unit 2 for ecological digestion, effectively degrading ammonia nitrogen, nitrite, etc. to purify the water quality; the separated manure and sewage are subjected to resource treatment such as anaerobic fermentation after precipitation and concentration, so as to be able to prepare biogas, organic fertilizers, insect feed, etc., and realize the increase of income from the sales of by-products.

[0062] It should be noted that the factory aquaculture system of this fish pond realizes industrialization of traditional fish pond aquaculture technology with the help of the aquaculture unit 1, the ecological purification unit 2, the precipitation unit 3 and the resource utilization unit 4. It is not necessary to carry out large-scale transformation of the fish pond. It only needs to set the aquaculture unit 1 and the precipitation unit 3 in a small area of the fish pond, and use the fish pond to set up the ecological purification unit 2 to achieve it. It can not only greatly increase the aquatic product output, but also solve the environmental protection problems brought by the discharge of tail water and manure and sewage, and is suitable for large-scale promotion.

[0063] It should be noted that the aquaculture system is not limited to fish farming, but can be applied to various aquaculture such as fish, shrimps, and crabs. Moreover, multiple aquaculture ponds 11 are provided in the aquaculture pond to enable the aquaculture of multiple varieties of aquatic products, which is conducive to increasing the types of aquaculture and achieving large-scale production, thereby increasing production and income.

[0064] Furthermore, the water area 100 includes pond water areas, river water areas, lake water areas, or reservoir water areas. That is to say, although the aquaculture system is named "factory-style fishpond", it is not limited to the transformation of fishponds and aquaculture within fishponds. Factory-style aquaculture can be realized in any water area 100. For example, large water surfaces such as rivers, lakes, reservoirs, river channels, tidal flats, low-lying subsidence areas, and haizi, or fishponds, pools, etc.

[0065] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
