Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to a convenient aquaculture tail water ecological treatment device. Background Art

[0002] Aquaculture tailwater refers to the water discharged during the aquaculture process after the water quality changes due to factors such as the metabolism of farmed animals, feed residues, drug use, and various biological activities in the water body. These tailwaters contain a large amount of organic matter, inorganic salts, nutrients such as nitrogen and phosphorus, as well as possible drug residues. If they are discharged directly without proper treatment, they will cause serious pollution to the surrounding natural waters, causing eutrophication of water bodies, ecological imbalance and other problems. Therefore, it is particularly important to carry out ecological treatment of aquaculture tailwater. Ecological treatment can not only effectively remove harmful substances in tailwater and improve water quality, but also realize the recycling of resources, reduce negative impacts on the environment, and promote the sustainable development of aquaculture.

[0003] Although there are some aquaculture tailwater ecological treatment devices on the market, these devices still have some technical defects in practical application. Specifically, the following problems are particularly prominent: First, in the existing aquaculture tailwater ecological treatment devices, the aeration box is a key component used to inject air into the water body to increase the dissolved oxygen content. However, the existing aeration box is difficult to balance the air injection and the water passing speed, resulting in the dissolved oxygen content of some water bodies being difficult to quickly meet the demand. Usually, the aeration time needs to be extended, which reduces the purification efficiency of aquaculture tailwater; In addition, during the aquaculture process, especially in the high-density aquaculture mode, the discharge of aquaculture tailwater is often large. When the water is changed in a centralized manner, a large amount of tailwater quickly enters the ecological box of the ecological treatment device, and the filtration system in the ecological box may not be able to fully purify these tailwaters in a short time.

[0004] In summary, there is an urgent need for a convenient aquaculture tailwater ecological treatment device that can overcome the above-mentioned defects, improve treatment efficiency and water purification effect. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a convenient aquaculture tail water ecological treatment device, so that the aquaculture tail water can be fully treated in the aeration box and the ecological box, so as to achieve the effect of efficient purification and recycling of the aquaculture tail water.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a convenient aquaculture tail water ecological treatment device, comprising an aeration box, a filter box and an eco-box which are fixedly connected in sequence from left to right, the aeration box, the filter box and the eco-box are interconnected, the top of the eco-box is detachably connected with a solar panel, the aeration box, the filter box and the eco-box are electrically connected to the solar panel, one side of the lower part of the aeration box is connected with a water inlet pipe, an aeration device is arranged in the aeration box, the aeration device signal is connected with a controller, a plurality of first adjustment components and a plurality of second adjustment components are respectively arranged in the aeration box and the eco-box, one side of the first adjustment component and the second adjustment component are respectively fixedly connected with a first sliding component and a second sliding component, and the first sliding component and the second sliding component are respectively fixedly connected to the side walls of the aeration box and the eco-box;

[0007] The first sliding component is used to slide along the width direction of the aeration box and along the height direction of the aeration box to drive the first adjusting component to move. The first adjusting component adjusts its own gap by sliding along the width direction of the aeration box and along the height of the aeration box. Since the gap after adjustment by the first adjusting component is reduced, and the change in the path prolongs the time for bubbles to pass through the water body, the bubbles at the bottom of the aeration box slowly rise to the top along the gap of the first adjusting component; the second sliding component is used to slide along the width direction of the eco-box to drive the second adjusting component to move. The second adjusting component adjusts its own gap by sliding along the width direction of the eco-box, so that the amount of aquaculture tail water flowing into the eco-box slowly rises from top to bottom along the gap of the second adjusting component. The first sliding component and the second sliding component are both connected to the controller signal;

[0008] Bubbles are generated by the aeration device and the dissolved oxygen concentration in the aeration box is monitored and transmitted to the controller. The controller drives the first sliding assembly to adjust the gap between the first adjustment assemblies according to the dissolved oxygen concentration.

[0009] The technical principles of the above scheme are as follows:

[0010] The aquaculture tail water to be treated is transported to the aeration box through the water inlet pipe. The aeration device adds oxygen to the aquaculture tail water by generating bubbles. In the aeration box, the first sliding component adjusts the gap of the first adjusting component sliding along the width direction of the aeration box and along the height of the aeration box, so that the bubbles generated in the aeration box move in the gap of the first adjusting component to increase the rising flow path of the bubbles. When the bubbles rise to the top of the aeration box, they flow into the filter box. The aquaculture tail water flows into the eco-box through the filter box. In the eco-box, the second sliding component adjusts its own gap by adjusting the sliding of the second adjusting component along the width direction of the eco-box, so as to control the rising speed of the aquaculture tail water, increase the contact time and contact area between the aquaculture tail water and the biological medium in the eco-box, and obtain the treated aquaculture tail water.

[0011] The above scheme has the following beneficial effects:

[0012] 1. In this solution, the gap of the first adjusting component is adjusted by the first sliding component. The smaller the gap, the slower the bubbles rise and the longer the residence time, which can increase the contact time with organic matter in the water body and promote the oxidative decomposition of organic matter. By controlling the rising speed and path of the bubbles, it is helpful to reduce the breakage and merging of bubbles in the water body, thereby improving the utilization rate of oxygen. The disturbance effect of the bubbles generated by the gap of the first adjusting component during the rising process helps to enhance the mixing effect of the water body and make the dissolved oxygen, organic matter, etc. in the aquaculture tail water more evenly distributed. This adjustment method helps to optimize the aeration effect and improve the oxygen utilization efficiency to optimize the aeration effect.

[0013] 2. In this scheme, the rising speed of the water volume of the aquaculture tail water in the ecological box can be controlled by adjusting the gap of the second adjusting component through the second sliding component. The slow water volume speed of the aquaculture tail water allows the pollutants in the aquaculture tail water to have more time to be adsorbed and degraded by the biological medium, thereby improving the treatment efficiency of the ecological box; the suitable water volume speed and dissolved oxygen content of the aquaculture tail water in the ecological box provide a good environment for the growth and activity of microorganisms. The microorganisms can further remove organic matter, nitrogen, phosphorus and other pollutants in the aquaculture tail water through adsorption, degradation and other processes, thereby improving the water purification effect; by controlling the water volume speed of the aquaculture tail water and the contact time of the biological medium, the treatment process in the ecological box is made more stable and reliable, and the stable treatment process helps to reduce water quality fluctuations and differences in treatment effects, thereby improving the overall treatment efficiency.

[0014] 3. This solution reduces the waste of water resources by recycling the tail water of aquaculture. At the same time, by optimizing the treatment process, the utilization efficiency of biological media is improved and the treatment cost is reduced. The device adopts an ecological treatment method and does not add chemical agents to avoid secondary pollution. At the same time, by improving the treatment efficiency and resource utilization, it helps to reduce the negative impact on the environment and promote the sustainable development of the aquaculture industry.

[0015] Further, the first sliding assembly includes a driving box fixedly connected to the outer top wall of the aeration box and a first movable box fixedly connected to the inner wall of the aeration box, a servo motor is fixedly connected in the driving box, a worm is coaxially fixedly connected to the output shaft of the servo motor, and a worm wheel is provided on one side of the worm; a lead screw is fixedly connected to the worm wheel, and an end of the lead screw away from the worm wheel extends into the first movable box, a part of the lead screw located in the first movable box is threadedly connected to a nut seat, a first connecting plate arranged along the height direction of the aeration box is fixedly connected to the first nut seat, a plurality of first electric telescopic rods are fixedly connected to the first connecting plate, and the output shafts of the first electric telescopic rods all pass through the first movable box, extend into the aeration box, and are fixedly connected to the first adjustment assembly;

[0016] The servo motor and the first electric telescopic rod are both connected to the controller signal, a sliding shaft is slidably connected to the first connecting plate, and one end of the sliding shaft away from the first connecting plate is fixedly connected to the first adjustment component;

[0017] The dissolved oxygen concentration in the aeration tank is measured by an aeration device and transmitted to a controller. The controller indirectly infers the bubble rising speed and oxygen transfer efficiency by analyzing the change in dissolved oxygen concentration. When the bubble rising speed exceeds the controller threshold or the oxygen transfer efficiency is lower than the controller threshold, the controller outputs a signal to start the servo motor to drive the worm and the worm wheel to maintain a meshing state. When the worm and the worm wheel are meshed, the worm drives the turbine to rotate, thereby rotating the lead screw, and the nut seat slides along the thread direction of the lead screw to drive the first adjusting component to move along the height direction of the aeration box, and a plurality of first electric telescopic rods stretch or contract to drive the first adjusting component to move along the width direction of the aeration box.

[0018] Beneficial effects: The meshing of the worm and the worm wheel driven by the servo motor, and the threaded cooperation of the lead screw and the nut seat, can achieve precise control of the height direction of the first adjusting component in the aeration box. This control mechanism can dynamically adjust the rising path of the bubbles according to the real-time monitoring results of the dissolved oxygen concentration, thereby optimizing the transfer efficiency and utilization rate of oxygen, and the self-locking effect of the worm and the worm wheel can keep the first adjusting component stable in the aeration box; the stretching or contraction of the first electric telescopic rod can drive the movement of the first adjusting component in the width direction of the aeration box, and further adjust the channel width when the bubbles rise. This flexible adjustment method can quickly respond and adjust the rising speed of the bubbles according to actual needs, thereby ensuring the efficiency and stability of the aeration process.

[0019] Further, the first adjustment components each include a first adjustment plate respectively fixedly connected to the first electric telescopic rod, one side of the first adjustment plate is fixedly connected to a plurality of first quadrangular pyramids, the first quadrangular pyramids are arranged in a row at equal intervals on the first adjustment plate, two adjacent first adjustment plates are fixedly connected to the first quadrangular pyramids on the opposite sides thereof as a group of first adjustment components, and the spacing of each group of first adjustment plates along the length direction of the aeration box is a fixed distance, and the first adjustment plates on the adjacent first sliding components that are not provided with the first quadrangular pyramids on one side are fixedly connected;

[0020] When the first regulating plates in the same group slide along the width direction and the height direction of the aeration box, the first tetrahedral pyramids facing each other are displaced or overlapped to adjust the rising speed of the aquaculture tail water entering the ecological box.

[0021] Beneficial effects:

[0022] 1. The precise movement of the first regulating plate in the aeration box can effectively divert the rising bubbles. By adjusting the gap and position of the first tetrahedron, the flow path of the bubbles can be controlled so that the bubbles are more evenly distributed throughout the aeration box. This diversion effect not only improves the utilization rate of oxygen, but also promotes the uniform distribution of dissolved oxygen in the water body, which helps to improve water quality.

[0023] 2. When the first regulating plate moves in the aeration box, the sharp corners of the first quadrangular pyramid will cause disturbance and shearing effects on the rising bubbles. This disturbance and shearing helps to break the surface tension of the bubbles, making the bubbles smaller and more dispersed, thereby increasing the contact area between the bubbles and the water body. At the same time, the disturbance and shearing effects can also promote the mixing of organic matter and microorganisms in the water body, accelerating the oxidation and decomposition process of organic matter.

[0024] 3. The movement of the first regulating plate will also produce a wave effect in the aeration box, making the water body in a dynamic state. This wave helps to increase the turbulence intensity in the water body and improve the mass transfer efficiency. Turbulence can enhance the material exchange between the bubbles and the water body, allowing oxygen to dissolve into the water body more quickly, and also help to release harmful substances in the water body into the bubbles more quickly and discharge them with the bubbles rising.

[0025] 4. Through the combined effects of the above-mentioned diversion, disturbance shear and wave effects, this design can significantly improve the treatment effect and stability of the aeration box. The optimized bubble distribution and mass transfer efficiency allow oxygen to be more fully dissolved in the water body, providing a good environment for the growth and activity of microorganisms. The flowing water body also helps to reduce dead corners and sediments in the water body, keeping the water quality clean and stable. At the same time, since the water body will be transported to the filter box, the sediment in the water body will be deposited in the aeration box close to the filter box under the push of water, which is convenient for the subsequent recovery and treatment of the sediment in the aeration box.

[0026] Furthermore, a first water pipe is provided at the top of the aeration box, a first filter is provided at the connection point between the first water pipe and the aeration box, one end of the first water pipe away from the aeration box is connected to the filter box, a second water pipe is provided at the lower part of the filter box at the diagonal of the first water pipe, the second water pipe is connected to the lower part of the eco-box, a one-way valve is provided in the first water pipe and the second water pipe, and a Hall flowmeter connected to the controller signal is provided in the second water pipe;

[0027] The Hall flowmeter is used to monitor the amount of aquaculture tail water flowing through the second water pipe. The controller has a built-in flow threshold. When the amount of aquaculture tail water flowing through the second water pipe received by the controller is higher than the threshold, the controller outputs to the second sliding component, so that the second regulating component adjusts the rising speed of the aquaculture tail water entering the ecological box.

[0028] Beneficial effects: The first filter is used to filter out larger impurities and particulate matter when the water flows from the aeration box to the filter box, preventing them from entering the filter box and causing blockage; the one-way valve is set to prevent the aquaculture tail water from flowing back, avoiding the treated tail water and the filtered impurities from mixing again and polluting the water body; the Hall flow meter is used to monitor the water volume of the aquaculture tail water in real time, and the second regulating component adjusts the speed of the aquaculture tail water in the ecological box according to the flow change, avoiding the insufficient decomposition of organic matter caused by the excessively fast water flow rate of the aquaculture tail water in the ecological box when the water volume of the aquaculture tail water is too large.

[0029] Furthermore, a plurality of fillers for removing suspended matter are arranged in the filter box, the interior of the filter box is in an inverted terrace shape, and the diameter of the filter box gradually decreases from top to bottom.

[0030] Beneficial effects: The inverted terrace design allows the aquaculture tail water to gradually converge in the filter box, increasing the water volume and velocity of the aquaculture tail water, which is beneficial to the collision and attachment of suspended matter with the filler, thereby improving the removal efficiency of suspended matter. The filler provides a larger contact surface area, providing more attachment points for suspended matter, further enhancing the filtration effect; the inverted terrace design allows the water volume of the aquaculture tail water to be more concentrated at the bottom of the filter box, which is beneficial to push larger particles and suspended matter to the outlet, reducing their residence time in the filter box and the risk of clogging. The setting of the filler also helps to intercept suspended matter and prevent them from entering the ecological box and causing further clogging problems.

[0031] Further, the second sliding assembly includes a second movable box fixedly connected to the inner wall of the aeration box, a second connecting plate arranged along the height direction of the aeration box is fixedly connected in the second movable box, a plurality of second electric telescopic rods are fixedly connected to the second connecting plate, and the output shafts of the second electric telescopic rods all pass through the second movable box, extend into the aeration box, and are fixedly connected to the second adjustment assembly;

[0032] The second electric telescopic rod is connected to the controller signal;

[0033] The plurality of second electric telescopic rods are stretched or contracted to drive the second adjustment assembly to move along the width direction of the aeration box.

[0034] Beneficial effect: The second electric telescopic rod is connected to the controller signal, and the extension or contraction degree of the electric telescopic rod can be accurately controlled by the Hall flow meter data received by the controller, so that the second adjustment component can accurately move along the width direction of the aeration box, thereby adjusting the rising speed of the aquaculture tail water entering the ecological box.

[0035] Furthermore, an ecological frame is detachably connected to the eco-box, which divides the eco-box into an emergent layer, an attached layer and a submerged layer which are fixedly connected from top to bottom. The submerged layer is provided with a first planting box detachably connected to the ecological frame, and submerged plants are planted in the first planting box.

[0036] Beneficial effects: When aquaculture tail water passes through the submerged layer, it will come into contact with the roots and leaves of submerged plants. Submerged plants have a strong ability to absorb and transform pollutants: first, they can absorb nutrients such as nitrogen and phosphorus in the water through their roots, and transform them into organic matter through photosynthesis, thereby reducing the concentration of nutrient salts in the water. In addition, submerged plants can also absorb and accumulate salt in the tail water, reducing the adverse effects of salt on the ecological environment; secondly, submerged plants can slow down the flow of water, fix sediments through their roots, inhibit resuspension, and at the same time act as a trap for suspended matter to promote sedimentation, thereby improving the transparency of the water body. The increase in transparency helps to increase light intensity and further promote the growth and photosynthesis of submerged plants; at the same time, submerged plants can inhibit the growth of algae by competing for resources such as light, nutrients and space. Submerged plants can also secrete allelopathic substances, which can affect the physiological effects of algae, such as inhibiting the activity of antioxidant enzymes and alkaline phosphatase, thereby promoting the death and sedimentation of algae. Therefore, in the ecological treatment of aquaculture effluent, submerged plants can promote the ecological restoration process. They achieve the purpose of ecological treatment of aquaculture effluent by absorbing pollutants, improving water transparency, inhibiting algae growth and improving the underwater ecological environment.

[0037] Further, the second adjustment components are located in the attachment layer, and the second adjustment components include second adjustment plates respectively fixedly connected to the second electric telescopic rods, and a plurality of second quadrangular pyramids are fixedly connected to one side of the second adjustment plates, and the second quadrangular pyramids are arranged in a row at equal intervals on the second adjustment plates, and the opposite sides of two adjacent second adjustment plates fixedly connected to the second quadrangular pyramids constitute a group of second adjustment components, and the spacing of each group of second adjustment plates along the length direction of the eco-box is a fixed distance, and the second adjustment plates on the adjacent second sliding components that are not provided with the second quadrangular pyramids are fixedly connected on one side;

[0038] When the second adjustment plates of the same group slide along the width direction of the aeration box, the second quadrangular pyramids facing each other are displaced or overlapped;

[0039] A plurality of brushes are arranged between the second adjustment plates, and the top and bottom of the brushes are fixedly connected to the ecological frames at the top and bottom of the attachment layer respectively.

[0040] Beneficial effects:

[0041] 1. By controlling the degree of misalignment or overlap of the second tetrahedron, the width of the channel through which water flows through the attachment layer can be accurately adjusted. When the water flow velocity entering the eco-box is low, the degree of misalignment of the second tetrahedron can be reduced to widen the channel and allow the water to pass quickly. Conversely, when the water flow velocity entering the eco-box is high, the degree of misalignment of the second tetrahedron can be increased to narrow the channel, lengthen the path through which water flows, and increase the residence time of water in the attachment layer.

[0042] 2. The regulation of water flow velocity directly affects the residence time and contact of pollutants in the attachment layer. With the continuous flushing of water flow, microorganisms can gradually accumulate on the brushes and form biofilms. The biofilms can further decompose organic and inorganic matter in the water body and improve the water purification effect. The brushes will produce a certain resistance when water flows through. This resistance will cause the water flow to form more eddies and disturbances in the attachment layer. This disturbance helps to increase the contact opportunities between the water flow and the microorganisms and biofilms in the attachment layer, thereby improving the removal efficiency of pollutants.

[0043] 3. The brush will also generate a certain amount of resistance when water flows through. Under the synergistic effect of the brush and the second tetrahedron, this resistance will prompt the water flow to form more eddies and disturbances in the attachment layer. This disturbance helps to increase the contact opportunities between the water flow and the microorganisms and biofilms in the attachment layer, thereby improving the removal efficiency of pollutants.

[0044] Furthermore, the emergent layer is provided with a second planting box detachably connected to the top of the ecological frame, the second planting box is detachably connected to an air bag in a circumferential direction, a number of elastic parts are detachably connected between the second planting box and the ecological frame, a soil-raising board is fixedly connected to the second planting box, a number of emergent plants are planted on the soil-raising board, a number of root holes are opened at the bottom of the soil-raising board and the second planting box, the roots of the emergent plants are all located in the root holes, and the second planting box is located on the root side of the emergent plants and is provided with a number of water outlet holes connected to the ecological box.

[0045] Beneficial effects: Emergent plants absorb and transform nutrients (such as nitrogen, phosphorus, etc.) in the water body through their roots, effectively reducing the eutrophication of the water body. The root hole design on the soil plate enables the roots of the emergent plants to fully contact the water body, thereby improving the root absorption efficiency of pollutants. The setting of the airbag and the elastic part enables the second planting box to adaptively adjust according to the water level changes, maintain the appropriate position of the emergent plants in the water body, and avoid the leaves and stems of the emergent plants being soaked in water and dying due to water level fluctuations.

[0046] Further, the eco-box is connected with a water outlet pipe at the diagonal of the second water delivery pipe, a second filter is provided at the connection between the water outlet pipe and the eco-box, a multi-parameter water quality sensor is provided in the water outlet pipe, a circulation pipe is connected to the water outlet pipe, one end of the circulation pipe away from the water outlet pipe is connected with the circulation pipe and the water inlet pipe, a first valve is provided at the connection of the water outlet pipe, and a second valve is provided at one end of the water outlet pipe away from the circulation pipe, and the multi-parameter water quality sensor, the first valve and the second valve are all connected with the controller signal;

[0047] The multi-parameter water quality sensor can monitor the effluent quality in real time, including key indicators such as dissolved oxygen, pH value, temperature, turbidity, and nutrient concentration. The controller monitors whether the aquaculture tail water output from the eco-box meets the recycling standards based on the data fed back by the sensor. If it meets the standards, the second valve is opened to output the treated and purified aquaculture tail water for secondary utilization; if it does not meet the standards, the controller opens the first valve to allow the aquaculture tail water to enter the aeration box again from the circulation pipe for secondary treatment until it meets the recycling standards.

[0048] Beneficial effects: The controller makes intelligent judgments based on the data fed back by the multi-parameter water quality sensor, automatically controls the switch status of the first valve and the second valve, and realizes the recycling or secondary treatment of aquaculture tail water without human intervention, thereby improving the treatment efficiency. By recycling the aquaculture tail water that meets the standards, the consumption of fresh water sources can be reduced and water resources can be saved. At the same time, this design avoids the direct discharge of substandard tail water into the environment, thereby reducing the cost of environmental governance.

[0049] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The first sliding component is used to slide along the width direction and the height direction of the aeration box 3 to drive the movement of the first adjusting component. The first adjusting component adjusts its own gap by sliding along the width direction and the height direction of the aeration box 3. Since the gap after adjustment by the first adjusting component is reduced and the change in the path prolongs the time for the bubbles to pass through the water body, the bubbles at the bottom of the aeration box 3 slowly rise to the top along the gap of the first adjusting component; the second sliding component is used to slide along the width direction of the eco-box 1 to drive the movement of the second adjusting component. The second adjusting component adjusts its own gap by sliding along the width direction of the eco-box 1, so that the amount of aquaculture tail water flowing into the eco-box 1 slowly rises from top to bottom along the gap of the second adjusting component. The first sliding component and the second sliding component are both connected to the controller signal.

[0062] Bubbles are generated by the aeration device and the dissolved oxygen concentration in the aeration box 3 is monitored and transmitted to the controller. The controller drives the first sliding assembly to adjust the gap between the first adjusting assemblies according to the dissolved oxygen concentration.

[0064] The dissolved oxygen concentration in the aeration tank is measured by the aeration device and transmitted to the controller. The controller indirectly infers the bubble rising speed and oxygen transfer efficiency by analyzing the change in dissolved oxygen concentration. When the bubble rising speed exceeds the controller threshold or the oxygen transfer efficiency is lower than the controller threshold, the controller outputs a signal to start the servo motor to drive the worm 7 and the worm wheel 8 to maintain a meshing state. When the worm 7 and the worm wheel 8 are meshed, the worm 7 drives the turbine to rotate, thereby rotating the screw 10, and the nut seat 11 slides along the thread direction of the screw 10 to drive the first adjustment component to move along the height direction of the aeration box 3, and the first electric telescopic rods 13 stretch or contract to drive the first adjustment component to move along the width direction of the aeration box 3.

[0065] The first adjustment components all include first adjustment plates 12 respectively connected to the first electric telescopic rod 13 by screws, and a plurality of first quadrangular pyramids 14 are welded on one side of the first adjustment plate 12. The first quadrangular pyramids 14 are arranged in a row at equal intervals on the first adjustment plate 12. The opposite sides of two adjacent first adjustment plates 12 welded with the first quadrangular pyramids 14 constitute a group of first adjustment components, and the spacing of each group of first adjustment plates 12 along the length direction of the aeration box 3 is a fixed distance, and the first adjustment plates 12 on the adjacent first sliding components, where the side without the first quadrangular pyramids 14 is not provided, are welded.

[0066] When the first regulating plates 12 of the same group slide along the width direction and the height direction of the aeration box 3 , the first quadrangular pyramids 14 facing each other are displaced or overlapped to adjust the rising speed of the aquaculture tail water entering the ecological box 1 .

[0067] The specific implementation process is as follows: the aquaculture tail water to be treated is transported into the aeration box 3 through the water inlet pipe 5, and the aeration device adds oxygen to the aquaculture tail water by generating bubbles. In the aeration box 3, the dissolved oxygen concentration in the aeration tank is measured by the aeration device and transmitted to the controller. The controller indirectly infers the bubble rising speed and oxygen transfer efficiency by analyzing the change of dissolved oxygen concentration. When the bubble rising speed exceeds the controller threshold or the oxygen transfer efficiency is lower than the controller threshold, the controller outputs a signal to start the servo motor. The servo motor drives the meshing of the worm 7 and the worm wheel 8, and the threaded cooperation of the screw 10 and the nut seat 11 to achieve precise control of the height direction of the first adjustment plate 12 in the aeration box 3. In the process of the first quadrangular pyramid 14 moving in the height direction, the path of the bubbles between the first adjustment plates 12 is increased, and fluctuations are generated in the aeration box 3 to keep the water body dynamic. This fluctuation helps to increase the turbulence intensity in the water body and improve the mass transfer efficiency. The turbulence can enhance the material exchange between the bubbles and the water body, so that oxygen is dissolved into the water body more quickly, and also helps to release harmful substances in the water body into the bubbles more quickly and discharge them with the rising bubbles.

[0068] The three first electric telescopic rods 13 stretch or contract to drive the first adjustment plate 12 to move along the width direction of the aeration box 3. At this time, the first tetrahedrons 14 are mutually dislocated, and the gap through which the bubbles can pass in the water body becomes smaller. The pointed corners of the first tetrahedrons 14 facing each other will produce disturbance and shearing effects on the rising bubbles. Such disturbance and shearing help to break the tension on the surface of the bubbles, making the bubbles smaller and more dispersed, thereby increasing the contact area between the bubbles and the water body. At the same time, the disturbance and shearing effects can also promote the mixing of organic matter and microorganisms in the water body, accelerating the oxidation and decomposition process of organic matter.

[0069] When the first regulating plate 12 moves simultaneously along the width direction and the height direction of the aeration box 3, the first quadrangular pyramids 14 are mutually offset, which can effectively divert the rising bubbles, thereby controlling the flow path of the bubbles and making the bubbles more evenly distributed in the entire aeration box 3. This diversion effect not only improves the utilization rate of oxygen, but also promotes the uniform distribution of dissolved oxygen in the water body, which helps to improve the water quality. The water flowing in the aeration box 3 also helps to reduce dead corners and sediments in the water body, thereby keeping the water quality clean and stable.

[0070] Furthermore, since the aquaculture tail water flows from the aeration box 3 into the filter box 2 , the sediment in the water body will be deposited in the aeration box 3 close to the filter box 2 under the push of the water, which is convenient for the subsequent recovery and treatment of the sediment in the aeration box 3 .

[0071] Embodiment 2:

[0072] As attached Figure 1 and Figure 2As shown, the difference from Example 1 is that a first water pipe 25 is provided at the top of the aeration box 3, a first filter is provided at the connection point between the first water pipe 25 and the aeration box 3, the end of the first water pipe 25 away from the aeration box 3 is connected to the filter box 2, a plurality of fillers for removing suspended matter are provided in the filter box 2, the interior of the filter box 2 is in an inverted terrace shape, the inner diameter of the filter box 2 gradually decreases from top to bottom, a second water pipe 16 is provided at the diagonal of the first water pipe 25 at the lower part of the filter box 2, the second water pipe 16 is connected to the bottom of the eco-box 1, a one-way valve is provided in both the first water pipe 25 and the second water pipe 16, the setting of the one-way valve prevents the aquaculture tail water from flowing back, and avoids the treated tail water and the filtered impurities from mixing and polluting the water body again, and a Hall flowmeter connected to the controller signal is provided in the second water pipe 16.

[0073] The Hall flowmeter is used to monitor the amount of aquaculture tail water flowing through the second water pipe 16. The controller has a built-in flow threshold. When the amount of aquaculture tail water flowing through the second water pipe 16 received by the controller is higher than the threshold, the controller outputs to the second sliding component, so that the second regulating component adjusts the rising speed of the aquaculture tail water entering the eco-box 1.

[0074] The specific implementation process is as follows: when the aquaculture tail water treated by the aeration box 3 is transported to the filter box 2 through the first water pipe 25, it passes through the first filter screen to filter out larger impurities and particles when flowing from the aeration box 3 to the filter box 2, to prevent impurities and particles from entering the filter box 2 and causing blockage.

[0075] When the aquaculture tail water enters the filter box 2, the inverted terrace design in the filter box 2 makes the aquaculture tail water gradually converge in the filter box 2, increasing the water volume and velocity of the aquaculture tail water, which is beneficial to the collision and adhesion of suspended matter with the filler, thereby improving the removal efficiency of the suspended matter, providing a larger contact surface area for the filler, and thus providing more attachment points for the suspended matter in the aquaculture tail water, further enhancing the filtering effect; and the inverted terrace design makes the water volume of the aquaculture tail water more concentrated at the bottom of the filter box 2, which is beneficial to push larger particles and suspended matter to the outlet, reducing their residence time and clogging risk in the filter box 2, and the setting of the filler also helps to intercept suspended matter and prevent them from entering the ecological box 1 and causing further clogging problems.

[0076] When the aquaculture tail water filtered by the filter box 2 flows through the second water pipe 16 into the eco-box 1, the water volume of the aquaculture tail water is monitored in real time by a Hall flow meter, and the second regulating component adjusts the speed of the aquaculture tail water in the eco-box 1 according to the flow change, thereby avoiding the problem of insufficient decomposition of organic matter caused by excessively fast water flow rate of the aquaculture tail water in the eco-box 1 when the water volume of the aquaculture tail water is too large.

[0077] Embodiment 3:

[0078] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the difference from Example 2 is that the second sliding assembly includes a second movable box 20 welded to the inner wall of the aeration box 3, a second connecting plate 19 arranged along the height direction of the aeration box 3 is welded in the second movable box 20, and a plurality of second electric telescopic rods 21 are screwed to the second connecting plate 19, the output shafts of the second electric telescopic rods 21 all pass through the second movable box 20 and extend into the aeration box 3 and are screwed to the second adjustment assembly, and the second electric telescopic rods 21 are connected to the controller signal.

[0079] The plurality of second electric telescopic rods 21 are stretched or contracted to drive the second adjustment assembly to move along the width direction of the aeration box 3 .

[0080] An ecological frame 31 is detachably connected to the eco-box 1, and the ecological frame 31 divides the eco-box 1 into an emergent layer 26, an attachment layer 24 and a submerged layer 18 welded in sequence from top to bottom. The submerged layer 18 is provided with a first planting box 17 detachably connected to the ecological frame 31, and submerged plants are planted in the first planting box 17.

[0081] The second adjustment components are located in the attachment layer 24, and the second adjustment components include second adjustment plates 22 respectively screwed to the second electric telescopic rod 21, and one side of the second adjustment plate 22 is fixedly connected to a plurality of second quadrangular pyramids, and the second quadrangular pyramids are arranged in a row at equal intervals on the second adjustment plate 22. Two adjacent second adjustment plates 22 are fixedly connected to the opposite sides of the second quadrangular pyramids to form a group of second adjustment components, and the spacing between each group of second adjustment plates 22 along the length direction of the eco-box 1 is a fixed distance, and the second adjustment plates 22 on the adjacent second sliding components that are not provided with the second quadrangular pyramids are fixedly connected on one side.

[0082] When the second adjustment plates 22 of the same group slide along the width direction of the aeration box 3, the second quadrangular pyramids facing each other are displaced or overlapped.

[0083] A plurality of brushes 23 are disposed between the second adjustment plates 22 , and the top and bottom of the brushes 23 are welded to the ecological frames 31 at the top and bottom of the attachment layer 24 respectively.

[0084] The emergent layer 26 is provided with a second planting box 27 detachably connected to the top of the ecological frame 31, and the second planting box 27 is detachably connected to the air bag 29 on the outer circumference, and a plurality of elastic parts 30 are detachably connected between the second planting box 27 and the ecological frame 31. The elastic parts 30 drive the second planting box 27 to reset when the ecological box 1 does not perform aquaculture tail water treatment, and provide a support effect for the second planting box 27. A soil-raising plate 28 is welded inside the second planting box 27, and a plurality of emergent plants are planted on the soil-raising plate 28. A plurality of root holes are opened at the bottom of the soil-raising plate 28 and the second planting box 27, and the roots of the emergent plants are all located in the root holes. The second planting box 27 is located on the root side of the emergent plants and is provided with a plurality of water outlet holes connected to the ecological box 1.

[0085] The specific implementation process is as follows: when the aquaculture tail water enters the ecological box 1 from the filter box 2, it will first come into contact with the roots and leaves of submerged plants through the submerged layer 18 at the bottom. The submerged plants can absorb nutrients such as nitrogen and phosphorus in the water through their roots and convert them into organic matter through photosynthesis, thereby reducing the nutrient concentration in the water.

[0086] At the same time, submerged plants capture suspended matter and promote its sedimentation to improve the transparency of the water body. When the transparency increases, it helps to increase the light intensity, further promoting the growth and photosynthesis of submerged plants. The photosynthesis of submerged plants will increase the amount of oxygen contained in the aquaculture tail water. When the aquaculture tail water enters the attachment layer 24, the microorganisms can gradually accumulate on the brush 23 and form a biofilm. The oxygen released by the submerged plants through photosynthesis acts on the microorganisms on the brush 23. The microorganisms accelerate their metabolism in the presence of sufficient oxygen, thereby accelerating the decomposition of organic matter and improving the effect of water purification.

[0087] Furthermore, in the attachment layer 24, by controlling the degree of misalignment or overlap of the second tetrahedron, the width of the channel through which the water flows through the attachment layer 24 can be precisely adjusted. When the water flow velocity entering the eco-box 1 is low, the degree of misalignment of the second tetrahedron can be reduced to widen the channel and allow the water to pass quickly. On the contrary, when the water flow velocity entering the eco-box 1 is high, the degree of misalignment of the second tetrahedron can be increased to narrow the channel, lengthen the path through which the water flows, and increase the water flow resistance, thereby increasing the residence time of the water flow in the attachment layer 24. The brush 23 will also generate a certain amount of resistance when the water flows through. Under the synergistic effect of the brush 23 and the second tetrahedron, this resistance will prompt the water flow to form more eddies and disturbances in the attachment layer 24. This disturbance helps to increase the contact opportunities between the water flow and the microorganisms and biofilms in the attachment layer 24, thereby improving the removal efficiency of pollutants.

[0088] The air bag 29 can make the upper part of the second planting box 27 located on the soil plate 28 float on the water level line, preventing the leaves and stems of the emergent plants from being soaked and killed by water due to water level fluctuations; and the emergent plants absorb and transform nutrients in the water body through the roots immersed below the water level line, effectively reducing the eutrophication degree of the water body.

[0089] Embodiment 4:

[0090] As attached Figure 1 and Figure 2 As shown, the difference from Example 3 is that the eco-box 1 is connected to the outlet pipe 6 at the diagonal of the second water supply pipe 16, a second filter is provided at the connection between the outlet pipe 6 and the eco-box 1, a multi-parameter water quality sensor is provided in the outlet pipe 6, a circulation pipe is connected to the outlet pipe 6, the end of the circulation pipe away from the outlet pipe 6 is connected to the circulation pipe and the water inlet pipe 5, a first valve is provided at the connection of the outlet pipe 6, a second valve is provided at the end of the outlet pipe 6 away from the circulation pipe, and the multi-parameter water quality sensor, the first valve and the second valve are all connected to the controller signal.

[0091] The multi-parameter water quality sensor can monitor the effluent quality in real time, including key indicators such as dissolved oxygen, pH value, temperature, turbidity, and nutrient concentration. The controller monitors whether the aquaculture tail water output from the eco-box 1 meets the recycling standard based on the data fed back by the sensor. If it meets the standard, the second valve is opened to output the treated and purified aquaculture tail water for secondary utilization; if it does not meet the standard, the controller opens the first valve to allow the aquaculture tail water to enter the aeration box 3 again from the circulation pipe for secondary treatment until it meets the recycling standard.

[0092] The specific implementation process is as follows: when the treated aquaculture tail water discharged from the upper part of the ecological box 1 enters the second water pipe 16, the second filter screen is filtered again, and according to the monitoring of the water quality by the multi-parameter water quality sensor, the controller receives the monitoring data and standardizes it to determine whether the treated aquaculture tail water meets the recycling standard. If it meets the standard, the controller opens the second valve to output the treated and purified aquaculture tail water for secondary utilization; if it does not meet the standard, the controller opens the first valve to allow the aquaculture tail water to enter the aeration box 3 again from the circulation pipe for secondary treatment. The aquaculture tail water after secondary treatment passes through the outlet pipe 6 again and is monitored in real time by the multi-parameter water quality sensor. The controller repeats the above steps according to the new water quality data until the water quality meets the standard and is output.

[0093] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
