Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and in particular to a device for deep degradation of livestock and poultry breeding wastewater. Background Technology

[0002] Pollutants in livestock and poultry wastewater mainly originate from manure and urine generated during the flushing process. These pollutants include organic matter (such as residual antibiotics used to prevent livestock diseases), nitrogen, phosphorus, and heavy metals such as zinc and copper. Currently, wastewater treatment processes for livestock and poultry farming are mainly divided into two categories: physicochemical methods and biological methods. Initially, wastewater treatment relied on various physical and chemical technologies, including adsorption, membrane treatment, and electrochemical technologies. Subsequently, biotechnology developed, including anaerobic and aerobic biological treatment. Common treatment processes include upflow anaerobic sludge blanket (UASB) processes, anoxic / aerobic (A / O) processes, and sequencing batch reactors (SBRs). Biological methods are relatively inexpensive, have good treatment effects, and cause less environmental pollution. They can effectively remove nutrients from wastewater and have been widely used domestically and internationally for the treatment of livestock and poultry wastewater. However, biological treatment methods have stringent requirements for treatment conditions, and antibiotics have inhibitory and inactivating effects on microorganisms, affecting their survival or function and resulting in poor antibiotic biodegradability. Therefore, developing effective technologies for treating antibiotic-containing livestock and poultry wastewater is of great significance for reducing the spread of antibiotic-resistant animals (ARGs) in the natural environment.

[0003] Currently, livestock wastewater is mostly degraded using ozone catalytic towers. However, blockage of the effluent pipes during the degradation process can cause the liquid level inside the tower to rise, making it easy for wastewater to enter the ozone destructor and cause it to malfunction. Moreover, continuous aeration at the bottom of the tower can cause the liquid surface to churn and surge, leading to false triggering of the water immersion sensor due to wave impact, resulting in frequent and ineffective start-stop of the overflow mechanism. Therefore, a deep degradation device for livestock and poultry breeding wastewater is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the blockage of the effluent pipe during the degradation process causing the liquid level inside the tower to rise, which makes it easy for wastewater inside the tower to invade the ozone destroyer, thus causing it to malfunction. Furthermore, the continuous aeration at the bottom of the tower can easily cause the liquid surface to churn and surge, leading to false triggering of the water immersion sensor due to wave impact, resulting in frequent and ineffective start-stop of the overflow mechanism. Therefore, this invention proposes a deep degradation device for livestock and poultry breeding wastewater.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A deep degradation device for livestock and poultry breeding wastewater includes a degradation tower. An anti-accidental contact housing is fixedly connected to the top of the inner cavity of the degradation tower. A water immersion sensor is installed inside the anti-accidental contact housing. Two baffles are hinged to the lower part of the inner cavity of the anti-accidental contact housing, and the two baffles are inclined and facing each other. A spring is fixedly connected to the upper surface of the baffle, and the end of the spring away from the baffle is fixedly connected to the inner wall of the anti-accidental contact housing. An overflow cavity is fixedly connected to the top of the degradation tower. Two second electric actuators are installed inside the overflow cavity, and overflow baffles are fixedly connected to the output ends of the two second electric actuators. The overflow baffles are slidably connected to the overflow cavity. An overflow pipe is fixedly connected to the bottom of the overflow cavity. The bottom probe of the water immersion sensor is located inside the degradation tower at a height higher than the drain pipe, and the highest point of the drain pipe is a certain distance from the bottom probe of the water immersion sensor. The overflow cavity communicates with the interior of the degradation tower, and the connection between the overflow cavity and the degradation tower is sealed to prevent leakage of liquid and air.

[0006] The above technical solution further includes: An ozone recovery chamber is fixedly connected to the top of the degradation tower. A baffle plate is fixedly connected inside the ozone recovery chamber. An ozone recovery pipe is fixedly connected to the top of the ozone recovery chamber. The ozone recovery pipe is connected to the ozone recovery chamber, and the connection between the ozone recovery pipe and the ozone recovery chamber is sealed. There are three baffle plates arranged alternately inside the ozone recovery chamber, and several fine holes are opened on the baffle plates.

[0007] An ozone concentration sensor is installed inside the ozone recovery chamber. An excess recovery chamber is fixedly connected to the upper part of the ozone recovery chamber. A sliding chamber is fixedly connected inside the excess recovery chamber. A first electric actuator is fixedly connected inside the sliding chamber. A movable baffle is fixedly connected to the output end of the first electric actuator. The movable baffle is slidably connected to the first electric actuator. An ozone destroyer is connected to the end of the excess recovery chamber away from the ozone recovery chamber. The ozone destroyer is installed on the upper part of the degradation tower. The excess recovery chamber and the ozone recovery chamber are connected. A slot is opened on the side wall of the sliding chamber. The movable baffle slides along the sliding chamber so that the ozone recovery chamber and the excess recovery chamber are connected through the slot. Gas can enter the excess recovery chamber through the slot. In the initial state, the movable baffle is in contact with the side wall of the ozone recovery chamber.

[0008] An ozone connection pipe is fixedly connected to the lower part of the degradation tower. Several ozone nozzles are fixedly connected to the part of the ozone connection pipe located inside the degradation tower. An ozone generator is installed at the end of the ozone connection pipe away from the degradation tower. The ozone nozzles are arranged in a circular pattern, so that the ozone can be evenly distributed during the ozone delivery process. The ozone generator is connected to the end of the ozone connection pipe away from the degradation tower. The connection between the ozone connection pipe and the degradation tower is sealed to prevent leakage.

[0009] The bottom of the degradation tower is fixedly connected to a waste collection tank, and the bottom of the waste collection tank is fixedly connected to a waste discharge pipe. The waste discharge pipe passes through the bottom of the degradation tower and extends outward. The waste collection tank has an inverted conical structure. The top of the waste collection tank is sealed and fixedly connected to the inner wall of the degradation tower. The precipitated impurities that fall during the degradation process can eventually fall into the waste collection tank. A valve (not shown in the figure) is installed at the top of the waste discharge pipe.

[0010] The lower part of the degradation tower is fixedly connected to a wastewater inlet pipe, and the upper part of the degradation tower away from the overflow chamber is fixedly connected to a drain pipe. The inner cavity of the degradation tower is fixedly connected to a lower support filter plate above the wastewater inlet pipe, and the lower part of the drain pipe is fixedly connected to an upper limit filter plate. The part between the lower support filter plate and the upper limit filter plate is the catalytic reaction zone, and the catalyst is placed in this zone. The connection between the drain pipe and the wastewater inlet pipe and the degradation tower is sealed.

[0011] A catalyst discharge port is fixedly connected to the outer wall of the degradation tower at the upper part of the lower support filter plate, and a catalyst loading port is fixedly connected to the outer wall of the degradation tower at the lower part of the drain pipe. Both the catalyst discharge port and the catalyst loading port are connected to the interior of the degradation tower. Both the catalyst discharge port and the catalyst loading port are equipped with sealing caps on the side away from the degradation tower. The sealing caps are fixed to the catalyst discharge port and the catalyst loading port by bolts, and the connection part is provided with a sealing structure to effectively prevent leakage.

[0012] The present invention has the following beneficial effects: 1. In this invention, the anti-accidental triggering structure formed by the spring-hinged inclined baffle can effectively eliminate the impact of liquid surface surging. It can not only eliminate the false triggering of liquid level detection and avoid the false start of overflow structure, but also protect the water immersion sensor probe and ensure stable and reliable detection. Combined with the protective structure of the second electric push rod in the overflow cavity and the movable baffle, it can effectively avoid the risk of wastewater rushing to the top of the tower.

[0013] 2. In this invention, the degradation tower is defined by a lower support filter plate and an upper limit filter plate to define the catalytic reaction zone, which can stably support the spherical catalyst and effectively prevent the loss of packing material. The ozone nozzle at the bottom of the degradation tower evenly distributes gas to ensure that ozone reacts evenly in the catalytic zone. The waste generated during the degradation process falls and is collected in the collection tank for regular discharge. At the same time, it is equipped with an emergency bypass with a drive movable baffle with a first electric actuator. In case of excessive ozone concentration, some ozone can be sent to the ozone destroyer to reduce the safety risk of ozone leakage. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1, as Figure 4 , Figure 5 and Figure 7As shown, the system includes a degradation tower 1. An anti-accidental contact housing 24 is fixedly connected to the top of the inner cavity of the degradation tower 1. A water immersion sensor 26 is installed inside the anti-accidental contact housing 24. Two baffles 27 are hinged to the lower part of the inner cavity of the anti-accidental contact housing 24. The two baffles 27 are inclined and facing each other. A spring 29 is fixedly connected to the upper surface of the baffles 27. The end of the spring 29 away from the baffles 27 is fixedly connected to the inner wall of the anti-accidental contact housing 24. An overflow chamber 13 is fixedly connected to the top of the degradation tower 1. Two second electric actuators 23 are installed inside the overflow chamber 13. An overflow baffle 22 is fixedly connected to the output end of the two second electric actuators 23. The overflow baffle 22 and... The overflow chambers 13 are slidably connected, and an overflow pipe 14 is fixedly connected to the bottom of the overflow chambers 13. The bottom probe of the water immersion sensor 26 is located in the inner cavity of the degradation tower 1 at a height higher than the drain pipe 7, and the highest point of the drain pipe 7 is a certain distance away from the bottom probe of the water immersion sensor 26. The overflow chambers 13 are connected to the interior of the degradation tower 1, and the connection between the overflow chambers 13 and the degradation tower 1 is sealed to prevent leakage of liquid and gas. A wastewater inlet pipe 12 is fixedly connected to the lower part of the degradation tower 1, and a drain pipe 7 is fixedly connected to the upper part of the degradation tower 1 on the side away from the overflow chambers 13. The connection between the drain pipe 7 and the wastewater inlet pipe 12 and the degradation tower 1 is sealed.

[0018] In this embodiment, as Figure 7 As shown, after pretreatment, livestock and poultry breeding wastewater is sent into the degradation tower 1 through wastewater inlet pipe 12. During normal operation, continuous aeration at the bottom of the degradation tower 1 causes the water at the top to surge continuously. The splashing water droplets and undulating liquid surface will hit the bottom surface of the baffle 27. The two inclined baffles 27 can effectively intercept the surging waves and large-diameter splashing water. When the waves hit the bottom surface of the baffle 27, the baffle 27 will swing slightly around the hinge axis. Through the compression deformation of the spring 29 fixedly connected to the upper surface of the baffle 27, the impact kinetic energy is absorbed, effectively preventing the rigid baffle from rebounding and causing secondary impact. The fine water mist ensures that the water level will only rise steadily to the bottom probe position of the water immersion sensor 26 when the actual water level inside the tower continues to rise. This effectively eliminates aeration fluctuations and avoids the problem of false triggering of the water immersion sensor 26 caused by liquid surface turbulence. Moreover, most of the water contains impurities, which will adhere to the bottom surface of the baffle plate 27 as it is washed by the waves. The spring 29 set on the upper part of the baffle plate 27 can drive it to vibrate during the resetting process. Under the vibration effect, the water droplets and impurities attached to the bottom surface of the baffle plate 27 can be effectively shaken off, thereby preventing impurities from continuously adhering to the bottom surface of the baffle plate 27 and affecting the subsequent use effect.

[0019] like Figure 4 and Figure 5As shown, when the drain pipe 7 becomes blocked, the drainage volume decreases, causing the water level inside the degradation tower 1 to rise abnormally, posing a risk of overflow. During the water level rise, the water immersion sensor 26 detects that the actual water level has reached the threshold, and the second electric actuator 23 installed inside the overflow chamber 13 is immediately activated. The movement of the second electric actuator 23 drives the fixedly connected overflow baffle 22 to retract inward. The retraction of the overflow baffle 22 connects the inner cavity of the degradation tower 1 with the overflow chamber 13. At this time, excess water can quickly overflow into the overflow chamber 13 and finally be discharged outside the tower and collected through the overflow pipe 14 fixedly connected to the bottom of the overflow chamber 13. This quickly lowers the water level inside the degradation tower 1, preventing wastewater from continuously rising and invading the top ozone recovery chamber 8, effectively protecting components such as the water immersion sensor 26 and the ozone destroyer 10, and avoiding equipment failure caused by overflow. Under normal conditions, the overflow baffle 22 remains closed, effectively isolating the inner cavity of the degradation tower 1 from the overflow chamber 13, preventing ozone gas from seeping into the overflow chamber 13 and leaking out.

[0020] Example 2, as Figure 6 As shown, an ozone recovery chamber 8 is fixedly connected to the top of the degradation tower 1. A baffle plate 18 is fixedly connected inside the ozone recovery chamber 8. An ozone recovery pipe 11 is fixedly connected to the top of the ozone recovery chamber 8, and the ozone recovery pipe 11 communicates with the ozone recovery chamber 8. The connection between the ozone recovery pipe 11 and the ozone recovery chamber 8 is sealed. Three baffle plates 18 are staggered inside the ozone recovery chamber 8, and several fine holes are opened on the baffle plates 18. An ozone concentration sensor 25 is installed inside the ozone recovery chamber 8. An excess recovery chamber 9 is fixedly connected to the upper part of the ozone recovery chamber 8. A sliding chamber 20 is fixedly connected inside the excess recovery chamber 9. A fixed... A first electric actuator 21 is connected, and a movable baffle 19 is fixedly connected to the output end of the first electric actuator 21. The movable baffle 19 is slidably connected to the first electric actuator 21. An ozone destroyer 10 is connected to the end of the excess recovery chamber 9 away from the ozone recovery chamber 8. The ozone destroyer 10 is installed on the upper part of the degradation tower 1. The excess recovery chamber 9 is connected to the ozone recovery chamber 8. A slot is opened on the side wall of the sliding chamber 20. The movable baffle 19 slides along the sliding chamber 20 so that the ozone recovery chamber 8 and the excess recovery chamber 9 are connected through the slot. Gas can enter the excess recovery chamber 9 through the slot. In the initial state, the movable baffle 19 is in contact with the side wall of the ozone recovery chamber 8.

[0021] In this embodiment, the ozone exhaust gas generated in the degradation tower 1 enters the ozone recovery chamber 8 from the top, passing through three layers of baffles 18 in sequence. The staggered openings of the baffles 18 repeatedly deflect the airflow, causing water mist and sludge droplets carried in the exhaust gas to collide with the baffle surface and agglomerate into droplets. These droplets then fall back into the degradation tower 1 under their own weight, thus preventing liquid water and suspended matter from contaminating the detection probe of the ozone concentration sensor 25 and ensuring the long-term stability of the concentration detection within the ozone recovery chamber 8. When the ozone concentration in the ozone recovery chamber 8 is within the threshold range, the first electric actuator 21 remains extended, effectively sealing the chamber. The connection between the ozone recovery chamber 8 and the excess recovery chamber 9 is blocked, and all exhaust gas is transported to an external process for recycling via the ozone recovery pipe 11, effectively improving the utilization rate of ozone resources. When the ozone concentration in the ozone recovery chamber 8 exceeds the threshold, the movable baffle 19 can be retracted by the first electric push rod 21. The movable baffle 19 slides inward along the sliding chamber 20. The movement of the movable baffle 19 can connect the ozone recovery chamber 8 and the excess recovery chamber 9, allowing excess ozone to be diverted into the excess recovery chamber 9 and finally transported to the ozone destroyer 10 for harmless decomposition, effectively ensuring the safe operation of the device.

[0022] Example 3, as Figure 1 — Figure 3 As shown, an ozone connecting pipe 2 is fixedly connected to the lower part of the degradation tower 1. Several ozone nozzles 28 are fixedly connected to the part of the ozone connecting pipe 2 located inside the degradation tower 1. An ozone generator 3 is installed at the end of the ozone connecting pipe 2 away from the degradation tower 1. The ozone nozzles 28 are arranged in a circular pattern, so that the ozone can be evenly distributed during the ozone delivery process. The end of the ozone connecting pipe 2 away from the degradation tower 1 is connected to the ozone generator 3. The connection between the ozone connecting pipe 2 and the degradation tower 1 is sealed to prevent leakage.

[0023] In this embodiment, ozone generator 3 serves as the source of fresh ozone. The outlet of ozone generator 3 is connected to ozone connecting pipe 2. Ozone connecting pipe 2 is arranged in a branched layout with multiple ozone nozzles 28 arrayed on it. The ozone nozzles 28 have a porous aeration structure and are evenly distributed. When the device is running, ozone generator 3 starts up and produces fresh ozone, which is delivered to the inside of ozone connecting pipe 2. The ozone is evenly distributed in ozone connecting pipe 2 and between each branch, and then released outward from the micropores on the upper surface of each ozone nozzle 28. The fresh ozone is distributed into the catalytic reaction zone in the degradation tower 1 in the form of fine bubbles. The porous ozone nozzles 28 can effectively reduce the ozone bubble particle size, improve the gas-liquid contact interface, and avoid local aeration concentration that could lead to short-circuiting. This effectively ensures that the catalytic reaction in the degradation tower 1 proceeds uniformly, and works together with the recycled residual ozone to complete the deep degradation of pollutants in the wastewater.

[0024] like Figure 3As shown, a waste collection tank 15 is fixedly connected to the bottom of the degradation tower 1, and a waste discharge pipe 4 is fixedly connected to the bottom of the waste collection tank 15. The waste discharge pipe 4 passes through the bottom of the degradation tower 1 and extends out. The waste collection tank 15 has an inverted conical structure. The top of the waste collection tank 15 is sealed and fixedly connected to the inner wall of the degradation tower 1. The precipitated impurities that fall during the degradation process can finally fall into the waste collection tank 15. A valve (not shown in the figure) is installed on the upper part of the waste discharge pipe 4.

[0025] Solid impurities, catalyst debris, and suspended sediments from aquaculture wastewater generated during the degradation reaction can fall downwards under gravity and collect inside the waste collection tank 15. A valve is installed at the top of the waste discharge pipe 4. By periodically opening the valve, the sediments accumulated in the waste collection tank 15 can be discharged, completing the slag removal operation. At the same time, the inverted conical structure of the waste collection tank 15 also facilitates the collection of sediments towards the center, making it less likely for impurities to accumulate and effectively reducing the risk of clogging inside the degradation tower 1.

[0026] like Figure 3 As shown, a wastewater inlet pipe 12 is fixedly connected to the lower part of the degradation tower 1, and a drain pipe 7 is fixedly connected to the upper part of the degradation tower 1 on the side away from the overflow chamber 13. A lower support filter plate 16 is fixedly connected to the inner cavity of the degradation tower 1 above the wastewater inlet pipe 12, while an upper limit filter plate 17 is fixedly connected to the lower part of the drain pipe 7. The part between the lower support filter plate 16 and the upper limit filter plate 17 is the catalytic reaction zone, in which the catalyst is placed. The connection between the drain pipe 7 and the wastewater inlet pipe 12 and the degradation tower 1 is sealed. A catalyst discharge port 5 is fixedly connected to the outer wall of the degradation tower 1 at the upper part of the lower support filter plate 16, and a catalyst loading port 6 is fixedly connected to the outer wall of the degradation tower 1 at the lower part of the drain pipe 7. Both the catalyst discharge port 5 and the catalyst loading port 6 are connected to the interior of the degradation tower 1. Both the catalyst discharge port 5 and the catalyst loading port 6 are equipped with a sealing cap on the side away from the degradation tower 1. The sealing cap is fixed to the catalyst discharge port 5 and the catalyst loading port 6 by bolts, and the connection part is provided with a sealing structure to effectively prevent leakage.

[0027] The device can add catalyst to the catalytic reaction zone through the catalyst loading port 6, and discharge the spent catalyst through the catalyst discharge port 5 at the bottom, which facilitates the regular replacement and maintenance of the catalyst. The lower support filter plate 16 installed inside the degradation tower 1 can support the catalyst particles and prevent the catalyst from falling and clogging the lower pipeline and gas distribution structure. The upper limit filter plate 17 can limit the catalyst and prevent the catalyst from floating under the water flow, so that it can be discharged from the drain pipe 7 with the water flow. After the wastewater to be treated and ozone enter the catalytic reaction zone, they complete the deep oxidation and degradation under the action of the catalyst. The treated water passes through the space above the upper limit filter plate 17 and is discharged out through the drain pipe 7.

[0028] Example 4, as Figure 1 — Figure 7As shown, in this embodiment, under normal degradation conditions, livestock and poultry breeding wastewater is sent into the degradation tower 1 through the wastewater inlet pipe 12, flows upward through the catalytic zone composed of the lower support filter plate 16 and the upper limit filter plate 17, and the ozone generated by the ozone generator 3 is transported to the bottom of the inner cavity of the degradation tower 1 through the ozone connecting pipe 2 and sprayed upward evenly from the ozone nozzle 28, so as to fully contact the wastewater and complete the deep oxidation degradation under the action of the catalyst. The degraded wastewater can be discharged out of the tower through the drain pipe 7, while the ozone tail gas that did not participate in the reaction during the degradation process enters the ozone recovery chamber 8 upward through the ozone recovery pipe 11. The ozone is transported to an external process for recycling. When the ozone concentration sensor 25 detects that the ozone concentration in the ozone recovery chamber 8 exceeds the set threshold, the first electric actuator 21 is activated, which drives the movable baffle 19 to retract inward along the sliding chamber 20. At this time, the ozone recovery chamber 8 is connected to the excess recovery chamber 9, and the excess ozone exhaust gas can enter the excess recovery chamber 9 and finally be transported to the ozone destroyer 10 for decomposition. When the drain pipe 7 is blocked, the water level in the degradation tower 1 rises, posing a risk of overflow. When the actual liquid level continues to rise and comes into contact with the water immersion sensor... When the probe at the bottom of sensor 26 is activated, the second electric actuator 23 is activated and drives the overflow baffle 22 to retract inward, so that the inner cavity of the degradation tower 1 is connected to the overflow cavity 13. Wastewater overflows into the overflow cavity 13 and is discharged outside the tower through the overflow pipe 14 for collection, which quickly reduces the liquid level inside the tower and prevents water from rushing to the top. During the degradation process, catalyst wear debris and settled sludge can fall downward into the waste collection tank 15 for collection and are periodically discharged outside the tower through the waste discharge pipe 4. The catalyst packing can be replenished and replaced through the catalyst loading port 6 and the catalyst unloading port 5.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
