Description

Technical Field

[0001] The utility model relates to the technical field of breeding, in particular to a self-purifying ecological aquaculture pond. Background Art

[0002] In the process of large-scale aquaculture, due to the high stocking density and the large amount of feed, metabolites, organic debris and various nutrients will continue to accumulate in the water. The accumulation of these substances will affect the water quality, reduce the amount of dissolved oxygen, and may lead to the accumulation of toxic substances such as nitrite and sulfide, affecting the growth of farmed animals. Therefore, it is necessary to change the water regularly to discharge the excessive accumulation of harmful substances, improve water quality, and adjust salinity and transparency.

[0003] Water changes require a large amount of water resources and energy, increasing breeding costs. In addition, the discharged tail water contains high levels of organic matter, nutrients and other pollutants, which pose a threat to the external water environment. In order to address this problem, a Chinese invention patent with patent number "CN114436405A" and titled "A Freshwater Aquaculture System with In-situ Ecological Purification of Water Bodies" proposes an aquaculture system, which includes an aquaculture area, an ecological purification area, an inlet well and a drainage well. The aquaculture area and the ecological purification area are concentrically arranged, with the aquaculture area located in the center and the ecological purification area located around the aquaculture area; the inlet well and the drainage well are distributed in the ecological purification area; the ecological purification area is filled with granular fillers in layers, and the surface of the fillers in the ecological purification area is higher than the water level in the aquaculture area; the inlet well is connected to the aquaculture area through an inlet pipe, and a water pump is provided on the inlet pipe. The bottom of the inlet well is separated from the ecological purification area, and the surface of the inlet well is connected to the ecological purification area through a water distribution trough; the upper part of the drainage well is separated from the ecological purification area, and the bottom is connected to the ecological purification area through an outlet; the water in the drainage well is transported to the bottom mud layer at the bottom of the aquaculture area through a return pipe. The system uses a water pump to draw water from the aquaculture area to the water distribution trough on the surface of the outer ecological purification area. The water flows downward through the ecological purification area to remove pollutants such as organic matter and ammonia nitrogen in the aquaculture wastewater. The purified water flows back to the aquaculture area by gravity from the drainage area, economically solving the water purification problem in the freshwater aquaculture process. However, there are some problems with the system. The system achieves the purification effect by filling the granular filler in the ecological purification area in layers. However, after long-term use, the granular filler is prone to clogging, and the system has no way to deal with clogging. Once the problem of clogging occurs, the purification effect of the system will be greatly reduced, and the required purification needs will not be met at all. The maintenance cost of completely replacing the filler or regular cleaning and replacement is extremely high. Summary of the invention

[0031] The present application relates to a self-purifying ecological aquaculture pond. The aquaculture pond of the present application includes a breeding area and a purification area. The purification area can purify the water body, and the purified water flows back to the breeding area. After this cycle, the effect of cyclic purification treatment is achieved. The aquaculture pond has its own purification function and good self-purification effect, which greatly reduces the number of water changes and the consumption of water resources; it occupies a small area, has low construction and maintenance costs, and is easy to operate and manage. It does not require professional technicians, which greatly reduces the breeding cost. In addition, the present application is different from the existing aquaculture ponds with self-purification functions. The purification module set in the purification area of ​​the present application can be disassembled. Once a blockage problem occurs, it can be quickly disassembled for cleaning, which can effectively prevent the module from being blocked and ensure the effect of the next use. The purification area of ​​the present application can maintain a stable treatment effect under different environments, and there is no secondary pollution in the treatment process, which is more environmentally friendly and efficient.

[0032] Specifically, Figures 1-2 As shown, the aquaculture pond of the present application includes a breeding area 2, a purification area 3, a plug flow pump 6 and a plurality of purification modules 8. The breeding area 2 is a pond formed by surrounding a dam 1. The breeding area 2 formed by surrounding the dam 1 can be square or circular, or a structure of other shapes, as long as it meets the actual needs; the purification area 3 includes a diversion dam 4, and the diversion dam 4 is located in the dam 1 to divide the area inside the dam 1 into the breeding area 2 outside the diversion dam 4 and the purification area 3 inside the diversion dam 4. The inlet and outlet ends of the purification area 3 are connected to the breeding area 2. The purification area 3 is actually surrounded by the diversion dam 4 and part of the dam 1. Around the formed area, the purification area 3 and the breeding area 2 are interconnected, the water in the breeding area 2 flows into the purification area 3 for purification, and then flows out of the purification area 3, forming a cyclic process; the plug flow pump 6 is arranged in the purification area 3, which is used to drive the water body in the purification area 3 to flow, and the plug flow pump 6 is the power source for the entire water body circulation; a plurality of purification modules 8 are distributed in the purification area 3 at intervals along the flow direction of the water flow, and the purification module 8 is detachably connected between the diversion dam 4 and the dam 1 to adsorb and purify the water body in the purification area 3, and the purification module 8 is the main component for water purification in the purification area 3.

[0033] The aquaculture pond dam 1 of the present application adopts an earth slope or a hard slope with a slope ratio of no more than 1:2; the area of ​​the aquaculture zone 2 is no less than 80% of the total area of ​​the aquaculture pond, and is separated from the purification zone 3 by a diversion dam 4; the purification zone 3 is a strip channel with an average channel width of no less than 1m, a water depth of 1 to 1.2m, and an area of ​​no more than 20% of the total area of ​​the aquaculture pond.

[0034] In actual operation, the plug flow pump 6 is turned on, and the plug flow pump 6 drives the water flow in the purification area 3 to flow from the inlet end to the outlet end. The water flows in the purification area 3, and the water flowing through the purification module 8 is adsorbed and purified by the purification module 8. Then the purified water flows into the breeding area 2 through the outlet end of the purification area 3. The turbid or seriously polluted water in the breeding area 2 enters the purification area 3 from the inlet end of the purification area 3 for purification, and the cycle is repeated. This is a treatment measure when the water pollution in the breeding area 2 is serious;

[0035] When the water pollution in the breeding area 2 is not serious, that is, the water is relatively clean, the purification module 8 can be removed and the flow pump 6 can be started to automatically circulate the water in the breeding area 2 and the purification area 3, so that the entire breeding pond can be oxygenated and circulated, the dissolved oxygen and water fluidity of the water can be increased, and the aquatic living environment can be improved;

[0036] When the purification module 8 is used for a long time and there is a problem of clogging, the purification module 8 can be removed after purification is completed and cleaned and dried, which can effectively prevent the purification module 8 from being blocked and ensure the effect of the next use.

[0037] In some embodiments of the present application, the present embodiment optimizes the above-mentioned purification module 8, specifically, Figure 2 As shown, the purification module 8 of this embodiment includes a side net 11 and a skeleton 10. The side net 11 is filled with a lightweight ceramsite filler 12. The side net 11 wraps the lightweight ceramsite filler 12 to form a purification module 8 for adsorbing and purifying water. The side net 11 wraps the lightweight ceramsite filler 12, which does not affect the flow of water through the lightweight ceramsite filler 12, and the side net 11 is also convenient for cleaning. When the lightweight ceramsite filler 12 is blocked, it only needs to be flushed to complete the cleaning. For more serious blockages, the side net 11 can be directly disassembled for cleaning, and the cleaning effect is excellent; the skeleton 10 is arranged in the side net 11 to support the side net 11 and the side net 11 and the lightweight ceramsite filler 12 to form a block structure. The purpose of setting the skeleton 10 is to allow the purification module 8 to form a block structure for easy installation and disassembly.

[0038] The side net 11, the frame 10 and the lightweight ceramsite filler 12 of this embodiment form a conical block structure with a large top and a small bottom, which is clamped between the diversion dam 4 and the dam 1. The conical structure with a large top and a small bottom is convenient for installation, and the purification module 8 will not be stuck between the dam 1 and the diversion dam 4. At the same time, the purification module 8 with a large top and a small bottom can just fit tightly with the dam 1 and the diversion dam 4 on both sides.

[0039] The side net 11 completely wraps the entire frame 10, and is made of high-strength polyethylene net with a mesh size of 8 to 10 mm. The frame 10 is a stainless steel frame. The light ceramsite filler 12 has a bulk density of less than 0.3 g / cm 3 Lightweight shale water purification ceramsite, particle size is 15 ~ 30mm.

[0040] In this embodiment, there are multiple purification modules 8 which are fixed in the purification zone 3 at equal intervals. The distance between adjacent purification modules 8 is 5 to 10 m. The cross-sectional shape of a single purification module 8 is the same as that of the purification zone, and the thickness is 0.4 to 0.6 m.

[0041] In other embodiments of the present application, the above-mentioned purification zone 3 is further optimized. Figure 1 As shown, in the present embodiment, a plurality of aerators 9 are arranged in the purification area 3, and the aerators 9 are located between adjacent purification modules 8. In fact, 1 to 2 aerators 9 can be installed between adjacent purification modules 8, and the aerators 9 are water-lifting aerators.

[0042] In some preferred embodiments of the present application, the above-mentioned purification zone 3 is further optimized, such as Figure 1As shown, the purification area 3 of this embodiment is provided with a partition wall 7 on the side close to the inlet end, the two ends of the partition wall 7 are respectively fixed on the diversion dam 4 and the dam 1, and the plug flow pump 6 is installed on the partition wall 7. The purification area 3 is provided with a fish intercepting net 5 on the side of the inlet end, and the fish intercepting net 5 is a flexible fishing net with a mesh aperture of no more than 5 mm.

[0043] In actual use, when the water pollution in the breeding area 2 is serious, the plug flow pump 6 and the aerator 9 are turned on to drive the water in the purification area 3 to flow. The polluted water in the breeding area 2 enters the purification area 3 from the inlet end of the purification area 3, flows through the fish intercepting net 5 and the plug flow pump 6 in turn, passes through the purification module 8, and the polluted impurities in the water are adsorbed by the lightweight ceramsite filler 12 in the purification module 8. Under the aeration action of the aerator 9, it flows through the water for further purification treatment, passes through all the purification modules 8 and aerators, and flows out from the outlet end of the purification area 3 into the breeding area 2, and the cycle is repeated until the water purification reaches the required level.

[0044] When the purification module 8 is used for a long time, there is a problem of clogging. After the purification is completed, the purification module 8 can be removed and cleaned and dried, which can effectively prevent the purification module 8 from being blocked and ensure the effect of the next use;

[0045] When the water pollution in the breeding area 2 is not serious, that is, the water is relatively clean, the purification module 8 can be removed, and the flow pump 6 and the aerator 9 can be started to make the water in the breeding area 2 and the purification area 3 circulate automatically. In this way, the entire breeding pond can be oxygenated and circulated, the dissolved oxygen and water fluidity of the water can be increased, and the water living environment can be improved.
