Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment equipment, and more specifically, it relates to a manure treatment pond for livestock farms and a method for treating laying hen manure. Background Technology

[0002] Livestock manure mainly refers to the mixture of excrement and sewage from poultry and livestock raised by people. Since livestock manure contains a large amount of sewage, solid-liquid separation is required during treatment. The solid manure after separation can be used for fermentation and composting, while the sewage after separation needs to be treated by static sedimentation, anaerobic and aerobic processes to purify and remove pollutants such as ammonia nitrogen.

[0003] For example, Chinese patent CN111977934B discloses a livestock manure treatment device, which can effectively improve the dryness of manure by separating sewage and manure in the manure, making it easier to compost it, shortening the composting time, and improving work efficiency. At the same time, it can also make it easy to treat the separated sewage separately, preventing sewage from flowing randomly and causing damage to the environment. This facilitates comprehensive treatment of manure and improves its practicality and reliability.

[0004] In existing technologies, aerobic wastewater treatment requires an aeration system to provide oxygen to the activated sludge in the tank, supplying dissolved oxygen for the aerobic bacteria within the sludge to metabolize and efficiently decompose organic matter in the wastewater. However, due to the limited aeration range of the aeration system, the delivered oxygen cannot fully contact and mix with the activated sludge, thus reducing the oxygen supply effect on the aerobic bacteria. Summary of the Invention

[0005] To address the problems in related technologies, this invention proposes a manure treatment pond for livestock farms and a method for treating laying hen manure, in order to overcome the technical problem in existing related technologies where the limited aeration range of the aeration system prevents the delivered oxygen from fully contacting and mixing with the activated sludge, thereby reducing the oxygen supply effect and aerobic purification effect for aerobic bacteria.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a manure treatment pond for livestock farms, comprising an aeration tank and an aerator disposed on one side of the aeration tank. An air distribution mechanism is installed inside the aeration tank, comprising an air distribution network, multiple rotating air distribution pipes, and multiple oscillating drive components. The air distribution network is laid within the activated sludge layer in the aeration tank, with one end connected to the aerator. Multiple rotating air distribution pipes are connected to the air distribution network, allowing the aerator to simultaneously supply air to each rotating air distribution pipe via the network. The rotating air distribution pipes rotate under the pressure of the supplied air, delivering oxygen in a circular pattern into the aeration tank. Simultaneously, the rotating air distribution pipes agitate the activated sludge layer within the aeration tank. The oscillating drive components drive the rotating air distribution pipes to oscillate up and down during air distribution.

[0008] An adjustment mechanism is also installed on the air distribution pipeline, located on one side of the rotating air distribution component and the swing drive component. The adjustment mechanism can rotate and adjust the swing drive component to adjust the swing path when the swing drive component drives the rotating air distribution component to swing.

[0009] Furthermore, the air distribution network includes an air guide pipe and multiple air guide branches. One end of the air guide pipe is connected to the aerator. The multiple air guide branches are evenly distributed and laid in the activated sludge layer of the aeration tank, and one end of each air guide branch extends to the outside of the aeration tank and is connected to the air guide pipe. The multiple rotating air distribution components are evenly arranged and installed on each air guide branch.

[0010] Furthermore, the rotating air distribution assembly includes a connecting pipe, which is rotatably mounted on the air distribution network. An air distribution pipe is fixedly installed at the top end of the connecting pipe, and multiple nozzles are provided at both ends of the air distribution pipe, with the nozzles at both ends of the air distribution pipe arranged in opposite directions.

[0011] Furthermore, the swing drive assembly includes a universal ball connector, a connecting sleeve, and a guide sleeve. The universal ball connector is fixedly installed on the air distribution pipe network, and the bottom end of the connecting pipe is movably connected to the universal ball connector. The guide sleeve is rotatably installed on the outer ring of the universal ball connector, and a wave guide groove is provided on the guide sleeve. The connecting sleeve is fixedly installed on the outer ring of the connecting pipe, and a guide head is fixedly installed on the outer ring of the connecting sleeve. The guide head is slidably engaged in the wave guide groove.

[0012] Furthermore, the guide sleeve includes a chassis, which is rotatably mounted on the outer ring of the universal ball joint. A lower guide sleeve is fixedly mounted on the inner ring of the top surface of the chassis, and a plurality of connecting posts are fixedly mounted on the outer ring of the top surface of the chassis. An upper guide sleeve is fixedly mounted on the top of each connecting post. A wave groove is provided at the top of the lower guide sleeve and the bottom of the upper guide sleeve. The wave groove forms the wave guide channel between the lower guide sleeve and the upper guide sleeve.

[0013] Furthermore, the outer ring of the connecting sleeve is fixedly installed with multiple guide heads, which are symmetrically arranged in pairs. The wave guide groove is formed by connecting multiple V-shaped inclined grooves in sequence, and the multiple V-shaped inclined grooves are symmetrically arranged in pairs.

[0014] Furthermore, the adjustment mechanism includes a pneumatic pipe and a transmission assembly. The pneumatic pipe is connected and installed on the air distribution network and located on one side of the corresponding connecting pipe. An actuation rotation assembly is installed inside the pneumatic pipe. The pneumatic rotation assembly is connected to the chassis via the transmission assembly, so that the pneumatic rotation assembly can drive the chassis to rotate under the action of air pressure during aeration.

[0015] Furthermore, the pneumatic rotating assembly includes a bracket and a turbine, the bracket being fixedly installed inside the pneumatic pipe, and the turbine being rotatably installed on the front side of the bracket.

[0016] Furthermore, the transmission assembly includes a rotating shaft, a gear ring, and a transmission bevel gear. The transmission bevel gear is fixedly installed at the end of the turbine. The rotating shaft is rotatably installed at the upper end of the air pressure pipe. A driven bevel gear that meshes and drives with the transmission bevel gear is fixedly installed at the bottom end of the rotating shaft. A transmission gear is fixedly installed at the top end of the rotating shaft. The gear ring is fixedly installed on the outer ring of the chassis, and the gear ring meshes and drives with the transmission gear.

[0017] This invention discloses a method for treating laying hen manure, the specific steps of which are as follows:

[0018] The egg-laying hen manure is separated into solid and liquid components using a solid-liquid separator to obtain solid manure and wastewater. Carbon and fermentation agents are then added to the solid manure for composting.

[0019] Meanwhile, the separated wastewater is first fed into a sedimentation tank for settling, and then fed into an anaerobic tank where anaerobic bacteria decompose and purify the pollutants in the wastewater.

[0020] The wastewater is then transported to the aeration tank and aerated by an aerator. The aerator supplies air to the rotating aeration pipes within the activated sludge layer of the aeration tank through an air distribution network. Driven by the supplied air pressure, the rotating aeration pipes rotate, delivering oxygen in a circular pattern to the activated sludge layer. Simultaneously, the rotating aeration pipes agitate the activated sludge layer within the aeration tank. A swing drive component drives the rotating aeration pipes to swing up and down repeatedly, while an adjustment mechanism can rotate and adjust the swing path of the swing drive component. Through aeration and agitation of the activated sludge layer, the aerobic bacteria within the activated sludge layer come into full contact with the oxygen supplied by the aeration, thereby enabling the aerobic bacteria to decompose and purify the pollutants in the wastewater.

[0021] The present invention has the following beneficial effects:

[0022] 1. In this invention, multiple evenly arranged rotating air distribution pipes are installed within the sludge layer of the aeration tank via an air distribution network. When the aerator supplies air to each rotating air distribution pipe within the activated sludge layer of the aeration tank through the air distribution network, the rotating air distribution pipes rotate under the drive of the supplied air pressure, delivering oxygen in a circular pattern to the activated sludge layer. This increases the oxygen delivery range, allowing oxygen to fully contact and mix with the activated sludge, thus improving the oxygen supply effect on the aerobic bacteria within the activated sludge. Furthermore, the rotating air distribution pipes agitate the activated sludge layer within the aeration tank, improving the uniformity of mixing between the activated sludge and oxygen, thereby enhancing the wastewater purification treatment effect.

[0023] 2. In this invention, when the rotating gas distribution pipe rotates to distribute gas, the swaying drive component can drive the rotating gas distribution pipe to sway up and down repeatedly, thereby improving the gas distribution range and rotational stirring effect of the rotating gas distribution pipe, thus improving the uniformity of mixing of activated sludge and oxygen, and further improving the sewage purification treatment effect; and the swaying drive component can be rotated and adjusted by the adjustment mechanism to adjust the swaying path when the swaying drive component drives the rotating gas distribution component to sway, thereby further improving the gas distribution range and rotational stirring effect of the rotating gas distribution pipe.

Detailed Implementation

[0037] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0038] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0039] Example 1

[0040] Please see Figures 1-3As shown, this invention is a manure treatment pond for a livestock farm, including an aeration tank 1 and an aerator 2 installed on one side of the aeration tank 1. An air distribution mechanism 3 is installed inside the aeration tank 1. The air distribution mechanism 3 includes an air distribution network, multiple rotating air distribution pipes, and multiple oscillating drive components. The air distribution network is laid in the activated sludge layer inside the aeration tank 1. One end of the air distribution network is connected to the aerator 2. Multiple rotating air distribution pipes are all connected and installed on the air distribution network, so that the aerator 2 can simultaneously supply air to each rotating air distribution pipe through the air distribution network, and the rotating air distribution... The pipeline can rotate under the pressure of the supplied air, delivering oxygen in a circular pattern into the aeration tank 1. At the same time, the rotating air distribution pipeline can agitate the activated sludge layer in the aeration tank 1. The swing drive component can drive the rotating air distribution pipeline to swing up and down repeatedly when the rotating air distribution pipeline rotates to distribute air. An adjustment mechanism 4 is also installed on the air distribution pipeline on one side of the rotating air distribution component and the swing drive component. The adjustment mechanism 4 can rotate and adjust the swing drive component to adjust the swing path when the swing drive component drives the rotating air distribution component to swing.

[0041] When treating aquaculture wastewater, the wastewater is transported to aeration tank 1 and aerated by aerator 2. At this time, aerator 2 supplies air to each rotating air distribution pipe in the activated sludge layer of aeration tank 1 through the air distribution network. The rotating air distribution pipe can rotate under the drive of the supplied air pressure, delivering oxygen in a circular range into the activated sludge layer. The rotating air distribution pipe can also agitate the activated sludge layer in aeration tank 1. At the same time, the swing drive component drives the rotating air distribution pipe to swing up and down, and the adjustment mechanism 4 can rotate and adjust the swing drive component to adjust the swing path when the swing drive component drives the rotating air distribution component to swing. Through aeration and rotational agitation of the activated sludge layer, the aerobic bacteria in the activated sludge layer can fully contact the oxygen delivered by aeration, thereby enabling the aerobic bacteria to decompose and purify the pollutants in the wastewater.

[0042] The rotating aeration pipe delivers oxygen in a circular pattern to the activated sludge layer, increasing the oxygen delivery range and ensuring thorough mixing between the oxygen and activated sludge. This enhances the oxygen supply to the aerobic bacteria within the activated sludge. Furthermore, the rotating aeration pipe agitates the activated sludge layer in aeration tank 1, improving the uniformity of the mixing between the activated sludge and oxygen, thereby improving wastewater treatment efficiency. When the rotating aeration pipe rotates, the oscillating drive component drives it to oscillate up and down, increasing the aeration range and rotational mixing effect. The oscillating drive component can be adjusted via the regulating mechanism 4 to change its oscillation path, further enhancing the aeration range and rotational mixing effect, ultimately improving the uniformity of the mixing between activated sludge and oxygen and the wastewater treatment efficiency.

[0043] Example 2

[0044] Please see Figures 1-6 As shown, the difference between this embodiment and the above embodiment is that the air distribution network includes an air guide pipe 31 and multiple air guide branch pipes 32. One end of the air guide pipe 31 is connected to the aerator 2. The multiple air guide branch pipes 32 are evenly distributed and laid in the activated sludge layer of the aeration tank 1, and one end of each air guide branch pipe 32 extends to the outside of the aeration tank 1 and is connected to the air guide pipe 31. Multiple rotating air distribution components are evenly arranged and installed on each air guide branch pipe 32. The rotating air distribution component includes a connecting pipe 34, which is rotatably installed on the air distribution network. An air distribution pipe 33 is fixedly installed at the top end of the connecting pipe 34. Multiple nozzles 35 are provided at both ends of the air distribution pipe 33, and the nozzles 35 at both ends of the air distribution pipe 33 are arranged in opposite directions.

[0045] During aeration, the aerator 2 supplies air to each air branch pipe 32 through the air guide pipe 31. Then, the oxygen in the air branch pipe 32 is transported to the air distribution pipe 33 through the connecting pipe 34, and sprayed into the aeration tank 1 by the nozzles 35 at both ends of the air distribution pipe 33, supplying oxygen to the activated sludge layer in the aeration tank 1. Since the nozzles 35 at both ends of the air distribution pipe 33 are set in opposite directions, the air distribution pipe 33 can rotate under the pressure thrust of the oxygen output at both ends, thereby rotating the air distribution pipe 33 to distribute air, thereby increasing the air distribution range of the air distribution pipe 33. At the same time, the rotation of the air distribution pipe 33 can stir the activated sludge layer, so that the oxygen transported by the air distribution pipe 33 can be mixed more evenly with the activated sludge layer.

[0046] Example 3

[0047] Please see Figures 5-8 As shown, the difference between this embodiment and the above embodiments is that the swing drive assembly includes a universal ball connector 312, a connecting sleeve 313, and a guide sleeve. The universal ball connector 312 is fixedly installed on the air distribution network, and the bottom end of the connecting pipe 34 is movably connected to the universal ball connector 312. The guide sleeve is rotatably installed on the outer ring of the universal ball connector 312, and a wave guide groove 310 is provided on the guide sleeve. The connecting sleeve 313 is fixedly installed on the outer ring of the connecting pipe 34, and a guide head 311 is fixedly installed on the outer ring of the connecting sleeve 313. The head 311 slides and engages with the wave guide groove 310; the guide sleeve includes a chassis 36, which is rotatably mounted on the outer ring of the universal ball connector 312. A lower guide sleeve 37 is fixedly mounted on the inner ring of the top surface of the chassis 36, and a plurality of connecting posts 39 are fixedly mounted on the outer ring of the top surface of the chassis 36. An upper guide sleeve 38 is fixedly mounted on the top of the connecting posts 39. Wave grooves are provided at the top of the lower guide sleeve 37 and the bottom of the upper guide sleeve 38. The lower guide sleeve 37 and the upper guide sleeve 38 are surrounded by the wave grooves to form a wave guide groove 310.

[0048] When the air distribution pipe 33 rotates, it drives the connecting pipe 34 and the connecting sleeve 313 to rotate synchronously. At this time, the connecting sleeve 313 drives the outer ring guide head 311 to rotate in a circular motion along the wave guide groove 310. During the circular motion, the guide head 311 swings up and down under the guidance of the wave guide groove 310, thereby driving the air distribution pipe 33 to swing back and forth, so as to improve the air distribution range and mixing effect of the air distribution pipe 33, thereby improving the uniformity of the mixing of activated sludge and oxygen and the sewage purification treatment effect.

[0049] Furthermore, the outer ring of the connecting sleeve 313 is fixedly equipped with multiple guide heads 311, which are symmetrically arranged in pairs. The wave guide groove 310 is formed by multiple V-shaped inclined grooves connected in sequence, and the multiple V-shaped inclined grooves are symmetrically arranged in pairs. By setting multiple sets of symmetrically distributed guide heads 311 on the outer ring of the connecting sleeve 313, the connecting pipe 34 and the air distribution pipe 33 can be limited by the cooperation of multiple guide heads 311, thereby improving the stability of the air distribution pipe 33 when it swings and distributes air.

[0050] Example 4

[0051] Please see Figures 5-10 As shown, the difference between this embodiment and the above embodiment is that the adjusting mechanism 4 includes a pneumatic pipe 41 and a transmission assembly. The pneumatic pipe 41 is connected and installed on the air distribution network and is located on one side of the corresponding connecting pipe 34. A starting rotation assembly is installed inside the pneumatic pipe 41. The pneumatic rotation assembly is connected to the chassis 36 through the transmission assembly, so that the pneumatic rotation assembly can drive the chassis 36 to rotate under the action of air pressure during aeration. The pneumatic rotation assembly includes a bracket 46 and a turbine 45. The bracket 46 is fixedly installed on the pneumatic pipe 41. Inside 1, turbine 45 is rotatably mounted on the front side of bracket 46; the transmission assembly includes shaft 42, gear ring 44 and transmission bevel gear 47. Transmission bevel gear 47 is fixedly mounted on the end of turbine 45. Shaft 42 is rotatably mounted on the upper end of air pressure pipe 41. Driven bevel gear 48, which meshes and is connected to transmission bevel gear 47, is fixedly mounted on the bottom end of shaft 42. Transmission gear 43 is fixedly mounted on the top end of shaft 42. Gear ring 44 is fixedly mounted on the outer ring of chassis 36 and meshes and is connected to transmission gear 43.

[0052] When oxygen flows through the gas pipe 41 via the gas guide branch pipe 32, the turbine 45 starts to rotate under the drive of air pressure, and drives the transmission bevel gear 47 to rotate synchronously. Then, the transmission bevel gear 47 meshes and drives the driven bevel gear 48 to rotate, which in turn drives the rotating shaft 42 and the transmission gear 43 to rotate. The transmission gear 43 then meshes and drives the gear ring 44 to rotate, which in turn drives the chassis 36 to rotate. The chassis 36 then drives the lower guide sleeve 37, the upper guide sleeve 38 and the connecting column 39 to rotate synchronously, which in turn drives the wave guide groove 310 to rotate. Adjusting the position of the wave crests and troughs of the wave guide groove 310 adjusts the swaying trajectory of the gas distribution pipe 33. By adjusting the swaying trajectory of the gas distribution pipe 33, the gas distribution range and mixing effect of the gas distribution pipe 33 can be improved, thereby further improving the mixing uniformity of activated sludge and oxygen and the sewage purification treatment effect.

[0053] Example 5

[0054] This embodiment discloses a method for treating laying hen manure, the specific steps of which are as follows:

[0055] The egg-laying hen manure is separated into solid and liquid components using a solid-liquid separator to obtain solid manure and wastewater. Carbon and fermentation agents are then added to the solid manure for composting.

[0056] Meanwhile, the separated wastewater is first fed into a sedimentation tank for settling, and then fed into an anaerobic tank. Anaerobic bacteria decompose and purify the pollutants in the wastewater. The anaerobic bacteria decompose large organic molecules (such as proteins and fats) to generate small molecule acids and alcohols, which are eventually converted into methane (biogas) and carbon dioxide. The COD removal rate can reach more than 80%.

[0057] The wastewater is then transported to aeration tank 1 and aerated by aerator 2. Aerator 2 supplies air to the rotating air distribution pipes in the activated sludge layer of aeration tank 1 through the air distribution network. The rotating air distribution pipes rotate under the pressure of the supplied air, delivering oxygen in a circular pattern to the activated sludge layer. The rotating air distribution pipes also agitate the activated sludge layer in aeration tank 1. At the same time, the swing drive component drives the rotating air distribution pipes to swing up and down repeatedly, and the adjustment mechanism 4 can adjust the swing drive component to adjust the swing path of the rotating air distribution component. Through aeration and rotational agitation of the activated sludge layer, the aerobic bacteria in the activated sludge layer come into full contact with the oxygen supplied by the aeration, thereby enabling the aerobic bacteria to decompose and purify the pollutants in the wastewater. The aerobic bacteria efficiently degrade small molecule organic matter through aerobic respiration, further removing residual organic matter and nutrients (nitrogen and phosphorus), so that the water quality meets the discharge standards.
