Description

Technical Field

[0001] This invention relates to the technical field of livestock wastewater treatment, and in particular to a poultry farm wastewater treatment device. Background Technology

[0002] Poultry farming generates wastewater that needs treatment. Chinese invention patent CN116161761B discloses a wastewater treatment device for poultry farming. This device includes a movable column, a spray pipe, and a second flexible hose. A first liquid pump draws water from the treatment tank into the spray pipe, which then sprays it out through the nozzle. The output of a first servo motor drives a first lead screw to rotate, which in turn moves the movable column. The spray pipe moves downwards, and a rack drives a transmission gear to rotate. The transmission gear then drives a second lead screw to rotate, which in turn moves a movable block, causing the spray pipe to move. The spray pipe pushes a baffle to move. When the movable column moves upwards, the second lead screw moves the spray pipe back to its original position. This reciprocating motion reduces the adhesion of flocculants to the outside of the spray pipe and ensures thorough mixing of the flocculant and wastewater inside the treatment tank.

[0003] In actual poultry farming, most wastewater comes from cleaning wastewater in chicken houses and from manure. This wastewater contains a large number of bacteria and pathogens. The wastewater treatment equipment mentioned above mainly treats poultry wastewater through flocculation and sedimentation, without special disinfection and sterilization treatment. As a result, the treated wastewater can still cause infection in poultry and easily make them sick. Therefore, improvements are needed. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a poultry farming wastewater treatment device capable of biological treatment and high-temperature disinfection and sterilization of wastewater, reducing the risks of wastewater to poultry and lowering the energy consumption of sterilization treatment.

[0005] This invention discloses a poultry farm wastewater treatment device, comprising a treatment tank and a partition. The treatment tank contains a treatment chamber, and the partition, installed in the middle of the treatment tank, divides the treatment chamber into left and right parts. It also includes a solid-liquid separation component, an outlet pipe, a solar thermal pipe assembly, a water tank, a high-temperature pipe, and a low-temperature pipe. The right side of the treatment chamber is a biological treatment chamber, and the left side is a high-temperature sterilization chamber. The high-temperature sterilization chamber is equipped with an outlet pipe. The solid-liquid separation component is installed on the upper left side of the treatment tank and is used to separate the solid and liquid phases in the wastewater. The inlet end of the outlet pipe extends into the solid-liquid separation component, and the outlet pipe outputs the wastewater. The solar thermal pipe array, equipped with multiple output heads, is installed at an angle above the treatment tank, with its lower end positioned at the upper right side of the tank. Multiple solar tubes are connected to the array, with water tanks installed between them. The multiple output heads of the outlet pipes are aligned with the upper ends of these water tanks. The input end of the high-temperature tube is connected to the outlet end of the solar thermal pipe array, and its output end extends into the high-temperature sterilization chamber of the treatment tank. The input end of the low-temperature tube extends into the biological treatment chamber of the treatment tank. A heat exchange assembly is installed between the high-temperature and low-temperature tubes, and the output end of the low-temperature tube is connected to the inlet end of the solar thermal pipe array. The multiple solar tubes of the solar thermal pipe array generate heat when exposed to sunlight. The medium inside the solar thermal pipe array is heated and then fed into the heat exchange assembly through a high-temperature pipe, and then returned to the solar thermal pipe array through a low-temperature pipe, creating a circulating heating system. Nitrifying bacteria for wastewater treatment are cultivated in the biological treatment chamber of the treatment tank. During operation, multiple solar tubes in the solar thermal pipe array generate heat from sunlight, heating multiple water tanks. Poultry farm wastewater is fed into a solid-liquid separation assembly for solid-liquid separation, separating solid impurities such as feces from the water. The wastewater is then transported through an outlet pipe to the top of multiple water tanks, flowing downwards into the biological treatment chamber of the treatment tank. During this flow, the wastewater is further aerated. The wastewater is heated and partially evaporated for initial concentration. The pre-concentrated wastewater then enters the biological treatment chamber of the treatment tank, where it is biologically decomposed by nitrifying bacteria and other microorganisms. The heat exchange components in the biological treatment chamber maintain the high activity of the nitrifying bacteria. After biological decomposition, the wastewater passes through a partition into the high-temperature sterilization chamber of the treatment tank. The heat exchange components sterilize the wastewater in the high-temperature sterilization chamber at high temperatures. The sterilized wastewater is then discharged through the effluent pipe of the treatment tank. Compared with existing technologies, this method can perform biological treatment and high-temperature sterilization of wastewater, reducing the risk of wastewater causing infectious diseases to poultry and reducing poultry diseases. By using a solar energy system, the energy consumption of the sterilization process is reduced.

[0006] Preferably, the heat exchange assembly includes a high-temperature heat dissipation pipe, a low-temperature heat dissipation pipe, and a connecting pipe. The high-temperature heat dissipation pipe is equipped with multiple heat exchange tubes (I), which are arranged at the bottom of the high-temperature sterilization chamber of the treatment tank. The input end of the high-temperature heat dissipation pipe is connected to the output end of the high-temperature heat dissipation pipe, and the input end of the connecting pipe is connected to the output end of the high-temperature heat dissipation pipe. The output end of the connecting pipe is connected to the input end of the low-temperature heat dissipation pipe. The low-temperature heat dissipation pipe is equipped with multiple heat exchange tubes (II), which are arranged at the bottom of the biological treatment chamber of the treatment tank. The output end of the low-temperature heat dissipation pipe is connected to the input end of the low-temperature heat dissipation pipe. The high-temperature medium at the output end of the solar heat pipe group is input into the high-temperature heat dissipation pipe through the high-temperature pipe. The multiple heat exchange tubes (I) of the high-temperature heat dissipation pipe input the heat of the high-temperature medium into the wastewater in the high-temperature sterilization chamber of the treatment tank for high-temperature sterilization. After the medium temperature decreases, it is input into the low-temperature heat dissipation pipe through the connecting pipe. The multiple heat exchange tubes (II) of the low-temperature heat dissipation pipe input the residual heat in the medium into the biological treatment chamber to heat the wastewater to a suitable temperature for bacteria. The low-temperature medium flows back to the solar heat pipe group through the low-temperature pipe for circulating heating, which has good practicality.

[0007] Preferably, it also includes multiple baffles, with multiple baffles evenly installed in multiple water tanks; the multiple baffles block the sewage flowing through the multiple water tanks, prolonging the time the sewage flows in the multiple water tanks and improving the sewage preheating effect.

[0008] Preferably, it also includes a packing layer, with the packing layer inside the partition. The packing layer includes a heat insulation material layer and a filter material layer. By setting the packing layer in the partition, the heat insulation material prevents the high-temperature sterilization chamber of the treatment tank from transferring heat to the biological treatment chamber, thus preventing the bacteria in the biological treatment chamber from being inactivated. The filter material layer intercepts impurities in the sewage and forms a bacterial bed, which is practical.

[0009] Preferably, it also includes an upper baffle, which is installed on the right side of the biological treatment chamber of the treatment tank. A gap is provided between the lower end of the upper baffle and the bottom wall of the treatment tank. The upper baffle is located on the left side of the lower end of multiple water tanks. Wastewater flowing through the multiple water tanks falls into the right side of the upper baffle. The upper baffle intercepts floating objects in the wastewater. The wastewater flows into the biological treatment chamber of the treatment tank through the gap between the lower end of the upper baffle and the treatment tank, where it collects and facilitates the cleaning of floating objects, improving convenience.

[0010] Preferably, it also includes a component analyzer, which is installed in the high-temperature sterilization chamber of the treatment tank. The component analyzer is used to detect the salt concentration in the wastewater in the high-temperature sterilization chamber of the treatment tank. When the wastewater in the high-temperature sterilization chamber of the treatment tank undergoes high-temperature sterilization, a large amount of water evaporates, which increases the concentration of salts such as nitrogen, phosphorus, and potassium in the remaining wastewater. The component analyzer detects the concentration of the salts. When the concentration reaches a set value, the wastewater is discharged and collected through the effluent pipe, which facilitates the subsequent production of fertilizer through processes such as concentration and crystallization.

[0011] Preferably, the solid-liquid separation assembly includes a separation tank, an inlet pipe, a slag discharge pipe, a spiral guide plate, and a slag receiving pool. The separation tank has an internal separation chamber. The lower part of the separation tank is cylindrical. The inlet pipe is installed on the left side of the separation tank and connects to the upper part of the separation chamber. The inlet end of the slag discharge pipe connects to the bottom of the separation chamber. The spiral guide plate is installed in the separation chamber and has a spiral cross-section. The outer end of the spiral guide plate connects to the inner left wall of the separation tank and is located below the inlet pipe. The inlet end of the outlet pipe connects to the inner left wall of the separation tank. The end extends into the middle of the volute-shaped guide plate, and the slag receiving pool is installed below the separation box. The volute-shaped guide plate divides the separation chamber of the separation box from the outside to the inside, creating a volute-shaped rotating channel for sewage flow. Sewage is input into the separation chamber of the separation box through the inlet pipe. The sewage flows along the volute-shaped guide plate, causing the sewage to flow in a volute shape. This causes solid impurities in the sewage to separate from the water phase under the action of centrifugal force and accumulate at the bottom of the separation chamber of the separation box. After working for a period of time, the slag discharge pipe is opened to discharge the solid impurities into the slag receiving pool for recycling, facilitating subsequent treatment.

[0012] Preferably, it also includes a filter cartridge, which is installed at the inlet end of the outlet pipe and located in the middle of the spiral guide plate. Multiple filter holes are provided on the outer wall of the filter cartridge. The sewage collected in the middle of the spiral guide plate is input into the outlet pipe through the multiple filter holes of the filter cartridge, thereby filtering and intercepting the residual solid impurities in the sewage and improving the solid-liquid separation efficiency of the sewage.

[0013] Preferably, it also includes a gas collection hood, a gas pipe, a fan, fins, a gas-liquid separator, a water outlet pipe, and a gas outlet pipe. The gas collection hood is fitted over the upper port of the treatment tank. The inlet end of the gas pipe is connected to the gas collection hood, and the middle part of the gas pipe extends into the separation chamber of the separation box. The fan is installed in the inlet end of the gas pipe, and the fins are installed on the outer wall of the middle part of the gas pipe. The outlet end of the gas pipe is connected to the middle part of the gas-liquid separator, the inlet end of the water outlet pipe is connected to the lower end of the gas-liquid separator, and the inlet end of the gas outlet pipe is connected to the upper end of the gas-liquid separator. The gas collection hood gathers the evaporated water vapor and volatile gases in the treatment tank. The system collects water vapor and volatile gases, which are then extracted by the fan and transported outward through the gas pipe. As the water vapor and volatile gases pass through the middle of the gas pipe, they are cooled by the wastewater in the separation chamber of the separator. The cooling effect of the gas pipe is improved by the addition of fins. After cooling, the water vapor condenses into water, and the mixture of water, water vapor, and volatile gases is fed into the gas-liquid separator. The water accumulates at the bottom of the gas-liquid separator and is discharged through the water outlet pipe, while the water vapor and volatile gases accumulate at the top of the gas-liquid separator and are discharged through the gas outlet pipe. This facilitates subsequent treatment of the volatile gases and is highly practical.

[0014] Preferably, the system also includes multiple catalytic tubes, multiple catalyst mesh plates, and multiple ultraviolet lamps. The multiple catalytic tubes are arranged in the high-temperature sterilization chamber of the treatment tank. The output end of the gas outlet pipe is connected to the input end of the multiple catalytic tubes, and the output ends of the multiple catalytic tubes extend outside the treatment tank. Multiple catalyst mesh plates are installed in the multiple catalytic tubes, and multiple ultraviolet lamps are installed in the multiple catalytic tubes respectively. The gas outlet pipe introduces water vapor and volatile gases into the multiple catalytic tubes. As the volatile gases flow through the multiple catalytic tubes, they are irradiated by the ultraviolet rays emitted by the multiple ultraviolet lamps. This, combined with the catalytic oxidation and decomposition of the volatile gases by the multiple catalyst mesh plates, allows the multiple catalyst mesh plates to maintain high-efficiency catalysis, thereby improving the treatment effect of the volatile gases.

[0015] Compared with the prior art, the beneficial effects of the present invention are: it can perform biological treatment and high-temperature disinfection and sterilization of sewage, reduce the risk of sewage causing infection to poultry, reduce poultry diseases, and reduce the energy consumption of sterilization treatment by using a solar energy system.

Detailed Implementation

[0025] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0026] Example 1

[0027] like Figures 1 to 4 , Figure 6 and Figure 7As shown, a poultry farm wastewater treatment device includes a treatment tank 1 and a partition 2. The treatment tank 1 has a treatment chamber inside, and the partition 2 is installed in the middle of the treatment tank 1, dividing the treatment chamber into left and right parts. It also includes a solid-liquid separation component 3, an outlet pipe 4, a solar heat pipe assembly 5, a water tank 6, a high-temperature pipe 7, and a low-temperature pipe 8. The right side of the treatment chamber in the treatment tank 1 is a biological treatment chamber, and the left side is a high-temperature sterilization chamber. The high-temperature sterilization chamber in the treatment tank 1 has an outlet pipe. The solid-liquid separation component 3 is installed on the upper left side of the treatment tank 1 and is used to separate the solid and liquid phases in the wastewater. The inlet end of the outlet pipe 4 extends into the solid-liquid separation chamber. In the separation component 3, the effluent pipe 4 outputs wastewater. The effluent pipe 4 is equipped with multiple output heads. The solar thermal pipe assembly 5 is installed at an angle above the treatment tank 1, with its lower end located on the upper right side of the treatment tank 1. The solar thermal pipe assembly 5 is equipped with multiple solar tubes, and water tanks 6 are installed between each of the solar tubes. The multiple output heads of the effluent pipe 4 are aligned with the upper ends of the multiple water tanks 6. The input end of the high-temperature pipe 7 is connected to the outlet end of the solar thermal pipe assembly 5. The output end of the high-temperature pipe 7 extends into the high-temperature sterilization chamber of the treatment tank 1. The input end of the low-temperature pipe 8 extends into the biological treatment chamber of the treatment tank 1. A heat exchange assembly is installed between the high-temperature pipe 7 and the low-temperature pipe 8. The output end of pipe 8 is connected to the inlet end of solar heat pipe assembly 5; the heat exchange component includes a high-temperature heat dissipation pipe 9, a low-temperature heat dissipation pipe 10, and a connecting pipe 11. The high-temperature heat dissipation pipe 9 is equipped with multiple heat exchange tubes (first type), which are arranged at the bottom of the high-temperature sterilization chamber of the treatment tank 1. The input end of the high-temperature heat dissipation pipe 9 is connected to the output end of high-temperature pipe 7. The input end of the connecting pipe 11 is connected to the output end of high-temperature heat dissipation pipe 9, and the output end of the connecting pipe 11 is connected to the input end of low-temperature heat dissipation pipe 10. The low-temperature heat dissipation pipe 10 is equipped with multiple heat exchange tubes (second type), which are arranged at the bottom of the biological treatment chamber of the treatment tank 1. The output end of the low-temperature heat dissipation pipe 10 is connected to the inlet end of low-temperature pipe 8. The system includes an inlet connection; multiple baffles 12 are evenly installed in multiple water tanks 6; a packing layer 13 is provided inside the partition 2, the packing layer 13 includes a heat insulation material layer and a filter material layer; an upper baffle 14 is installed on the right side of the biological treatment chamber of the treatment tank 1, a gap is provided between the lower end of the upper baffle 14 and the bottom wall of the treatment tank 1, and the upper baffle 14 is located on the left side of the lower end of the multiple water tanks 6; and a component analyzer 15 is installed in the high-temperature sterilization chamber of the treatment tank 1, the component analyzer 15 is used to detect the salt concentration in the wastewater in the high-temperature sterilization chamber of the treatment tank 1.

[0028] Multiple solar tubes in the solar heat pipe array 5 generate heat when exposed to sunlight. The high-temperature medium at the output end of the solar heat pipe array 5 is input into the high-temperature heat dissipation pipe 9 through the high-temperature pipe 7. Multiple heat exchange tubes of the high-temperature heat dissipation pipe 9 transfer the heat from the high-temperature medium to the wastewater in the high-temperature sterilization chamber of the treatment tank 1 for high-temperature sterilization. After the medium temperature decreases, it is input into the low-temperature heat dissipation pipe 10 through the connecting pipe 11. Multiple heat exchange tubes of the low-temperature heat dissipation pipe 10 transfer the residual heat from the medium to the biological treatment chamber, heating the wastewater to a suitable temperature for bacteria. The low-temperature medium flows back to the solar heat pipe array 5 through the low-temperature pipe 8 for circulating heating, where it is cultivated in the biological treatment chamber of the treatment tank 1. In wastewater treatment, nitrifying bacteria and other components work by using solar thermal pipe array 5. Multiple solar tubes in the solar thermal pipe array 5 generate heat from sunlight, which in turn heats multiple water tanks 6. Poultry farm wastewater is fed into solid-liquid separation component 3 for solid-liquid separation, separating solid impurities such as feces from water. The wastewater is then transported through outlet pipe 4 to the upper part of the multiple water tanks 6. The wastewater flows downwards along the multiple water tanks 6 into the biological treatment chamber of treatment tank 1. Multiple baffles 12 obstruct the flow of wastewater through the multiple water tanks 6, prolonging the flow time and improving the preheating effect. During the wastewater flow, the wastewater is heated and some water evaporates, undergoing preliminary treatment. The concentrated wastewater falls to the right side of the upper baffle 14, which intercepts floating debris. The wastewater flows through the gap between the lower end of the upper baffle 14 and the treatment tank 1 into the biological treatment chamber of the treatment tank 1. In the biological treatment chamber, it is biologically decomposed by nitrifying bacteria and other microorganisms. The heat exchange components in the biological treatment chamber maintain the high activity of the nitrifying bacteria. The biologically decomposed wastewater then passes through the partition 2 into the high-temperature sterilization chamber of the treatment tank 1. By setting a packing layer 13 in the partition 2, the heat insulation material prevents heat transfer from the high-temperature sterilization chamber of the treatment tank 1 to the biological treatment chamber, thus preventing the inactivation of bacteria in the biological treatment chamber. The filter material... The system intercepts impurities in the wastewater and forms a bacterial bed. The heat exchange component sterilizes the wastewater in the high-temperature sterilization chamber at high temperature. During the high-temperature sterilization process, a large amount of water evaporates from the wastewater in the high-temperature sterilization chamber of treatment tank 1, which increases the concentration of nitrogen, phosphorus, potassium and other salts in the remaining wastewater. The component detector 15 detects the concentration of the salts. When the concentration reaches the set value, the wastewater is discharged and collected through the outlet pipe, which facilitates the subsequent production of fertilizer through processes such as concentration and crystallization. Compared with the existing technology, this system can perform biological treatment and high-temperature sterilization of wastewater, reduce the risk of wastewater causing infection to poultry, reduce poultry diseases, and reduce the energy consumption of sterilization treatment by using a solar energy system.

[0029] Example 2

[0030] like Figure 5As shown, based on Embodiment 1, the solid-liquid separation assembly 3 includes a separation tank 16, an inlet pipe 17, a slag discharge pipe 18, a spiral guide plate 19, and a slag receiving pool 31. The separation tank 16 has an internal separation chamber. The lower part of the separation tank 16 is cylindrical. The inlet pipe 17 is installed on the left side of the separation tank 16 and communicates with the upper part of the separation chamber. The input end of the slag discharge pipe 18 communicates with the bottom of the separation chamber. The spiral guide plate 19 is installed on the left side of the separation tank 16. In the separation chamber, the volute guide plate 19 has a spiral volute cross-section. The outer end of the volute guide plate 19 is connected to the inner left wall of the separation box 16. The outer end of the volute guide plate 19 is located below the inlet pipe 17. The inlet end of the outlet pipe 4 extends into the middle of the volute guide plate 19. The slag receiving pool 31 is installed below the separation box 16. The chamber also includes a filter cartridge 20, which is installed at the inlet end of the outlet pipe 4. The filter cartridge 20 is located in the middle of the volute guide plate 19. Multiple filter holes are provided on the outer wall of the filter cartridge 20.

[0031] The volute guide plate 19 divides the separation chamber of the separation box 16 from the outside to the inside, creating a volute-shaped rotating channel for sewage flow. Sewage is input into the separation chamber of the separation box 16 through the inlet pipe 17. The sewage flows along the volute guide plate 19, causing the sewage to flow in a volute shape. This allows solid impurities in the sewage to separate from the water phase under the action of centrifugal force and accumulate at the bottom of the separation chamber of the separation box 16. After working for a period of time, the slag discharge pipe 18 is opened to discharge the solid impurities into the slag receiving pool 31 for recycling and subsequent treatment. The sewage accumulated in the middle of the volute guide plate 19 is input into the outlet pipe 4 through multiple filter holes of the filter cartridge 20, filtering and intercepting the residual solid impurities in the sewage and improving the solid-liquid separation efficiency of the sewage.

[0032] Example 3

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 8As shown, based on Embodiment 2, it further includes a gas collection hood 21, a gas pipe 22, a fan 23, fins 24, a gas-liquid separator 25, a water outlet pipe 26, and a gas outlet pipe 27. The gas collection hood 21 covers the upper port of the treatment tank 1. The input end of the gas pipe 22 is connected to the gas collection hood 21, and the middle part of the gas pipe 22 extends into the separation chamber of the separation box 16. The fan 23 is installed in the input end of the gas pipe 22. The fins 24 are installed on the outer wall of the middle part of the gas pipe 22. The output end of the gas pipe 22 is connected to the middle part of the gas-liquid separator 25. The water outlet pipe 26... The input end of the gas-liquid separator 25 is connected to the lower end of the gas-liquid separator 25, and the input end of the gas outlet pipe 27 is connected to the upper end of the gas-liquid separator 25. It also includes multiple catalytic tubes 28, multiple catalyst mesh plates 29, and multiple ultraviolet lamps 30. The multiple catalytic tubes 28 are arranged in the high-temperature sterilization chamber of the treatment tank 1. The output end of the gas outlet pipe 27 is connected to the input end of the multiple catalytic tubes 28. The output ends of the multiple catalytic tubes 28 extend out of the outside of the treatment tank 1. The multiple catalyst mesh plates 29 are installed in the multiple catalytic tubes 28, and the multiple ultraviolet lamps 30 are respectively installed in the multiple catalytic tubes 28.

[0034] The gas collection hood 21 gathers and collects the water vapor and volatile gases evaporated in the treatment tank 1. The blower 23 operates to extract the water vapor and volatile gases and transport them outward through the gas pipe 22. When the water vapor and volatile gases pass through the middle of the gas pipe 22, they are cooled by the sewage cooling zone in the separation chamber of the separation box 16. The cooling effect of the gas pipe 22 is improved by setting fins 24. After cooling, the water vapor condenses into water, and the mixture of water, water vapor and volatile gases is input into the gas-liquid separator 25. The water accumulates at the bottom of the gas-liquid separator 25 and is discharged through the water outlet pipe 26. Water vapor and volatile gases accumulate at the top of the gas-liquid separator 25 and are discharged through the outlet pipe 27. The outlet pipe 27 inputs water vapor and volatile gases into multiple catalytic tubes 28. As the volatile gases flow through the multiple catalytic tubes 28, they are irradiated by ultraviolet rays emitted by multiple ultraviolet lamps 30. This, combined with the catalytic oxidation and decomposition of the volatile gases by multiple catalyst mesh plates 29, ensures that the multiple catalyst mesh plates 29 maintain high-efficiency catalysis and improves the treatment effect of volatile gases.

[0035] like Figures 1 to 8As shown, this invention discloses a poultry farm wastewater treatment device. During operation, multiple solar tubes of the solar heat pipe assembly 5 generate heat through sunlight. The high-temperature medium at the output end of the solar heat pipe assembly 5 is input into the high-temperature heat dissipation pipe 9 via the high-temperature pipe 7. Multiple heat exchange tubes of the high-temperature heat dissipation pipe 9 transfer the heat from the high-temperature medium to the wastewater in the high-temperature sterilization chamber of the treatment tank 1 for high-temperature sterilization. After the medium temperature decreases, it is input into the low-temperature heat dissipation pipe 10 via the connecting pipe 11. Multiple heat exchange tubes of the low-temperature heat dissipation pipe 10 transfer the residual heat from the medium into the biological treatment chamber, heating the wastewater to a suitable temperature for bacteria. The low-temperature medium flows back to the solar thermal pipe assembly 5 through the low-temperature pipe 8 for circulating heating. Then, multiple solar tubes in the solar thermal pipe assembly 5 heat multiple water tanks 6. Poultry farm wastewater is fed into the solid-liquid separation component 3 for solid-liquid separation, separating solid impurities such as feces from water. The wastewater is then transported through the outlet pipe 4 to the upper end of the multiple water tanks 6. The wastewater flows downwards along the multiple water tanks 6 into the biological treatment chamber of the treatment tank 1. During the wastewater flow, it is heated and some water evaporates for preliminary concentration. The preliminarily concentrated wastewater then enters the biological treatment chamber of the treatment tank 1. The wastewater undergoes biological decomposition by nitrifying bacteria and other microorganisms in the treatment tank. After biological decomposition, the wastewater passes through partition 2 and enters the high-temperature sterilization chamber of treatment tank 1. The high-temperature heat dissipation pipe 9 sterilizes and concentrates the wastewater in the high-temperature sterilization chamber. When the salt concentration in the wastewater reaches the set value, it is discharged and collected through the effluent pipe. Finally, the gas collection hood 21 gathers and collects the water vapor and volatile gases evaporated in treatment tank 1. The blower 23 operates to extract the water vapor and volatile gases and transport them outward through the gas pipe 22. When the water vapor and volatile gases pass through the middle of the gas pipe 22, they are cooled by the wastewater in the separation chamber of the separation box 16. After cooling, the water vapor condenses into water, and the mixture of water, water vapor, and volatile gases is fed into the gas-liquid separator 25. The water accumulates at the bottom of the gas-liquid separator 25 and is discharged through the water outlet pipe 26. The water vapor and volatile gases accumulate at the top of the gas-liquid separator 25 and are discharged through the gas outlet pipe 27. The gas outlet pipe 27 feeds the water vapor and volatile gases into multiple catalytic tubes 28. As the volatile gases flow through the multiple catalytic tubes 28, they are irradiated by ultraviolet light emitted by multiple ultraviolet lamps 30. This, combined with the catalytic oxidation and decomposition of the volatile gases by multiple catalyst mesh plates 29, allows for catalytic oxidation and decomposition.

[0036] The main functions achieved by this invention are:

[0037] 1. It can perform biological treatment and high-temperature disinfection and sterilization of sewage, reducing the risk of sewage causing infection to poultry and reducing poultry diseases;

[0038] 2. A solar heating system is used to reduce the energy consumption of the sterilization process;

[0039] 3. Solid-liquid separation of wastewater is achieved through a spiral channel, facilitating subsequent treatment of solid impurities;

[0040] 4. It can perform efficient catalytic oxidation treatment on volatile gases.

[0041] The poultry farming wastewater treatment device of the present invention uses common mechanical methods for installation, connection, or setup, and can be implemented as long as it can achieve its beneficial effects.
