Description

Technical Field

[0001] This invention relates to the technical field of slaughterhouse wastewater treatment, and more particularly to a slaughterhouse wastewater treatment apparatus and method. Background Technology

[0002] In the meat processing industry, slaughter wastewater treatment is a crucial step. The wastewater generated during slaughter contains a large amount of organic matter, grease, blood, hair, meat scraps, and possible microorganisms and pathogens. If it is discharged directly without proper treatment, it will not only cause serious environmental pollution but may also pose a threat to human health.

[0003] Most existing slaughterhouse wastewater treatment facilities adopt traditional biological treatment methods, such as activated sludge and biofilm processes. While these methods can effectively remove pollutants from wastewater to a certain extent, they usually require the construction of multiple tanks, including equalization tanks, primary sedimentation tanks, anaerobic tanks, aeration tanks, secondary sedimentation tanks, and disinfection tanks, which occupy a large area. In addition, due to the need to install complex mechanical equipment and a large number of pipeline systems, as well as to employ professional operators and maintenance personnel, the construction and operation costs of existing facilities are relatively high.

[0004] For small slaughterhouses, due to limited space and tight funds, existing slaughter wastewater treatment equipment is often unsuitable. Some small slaughterhouses even choose to discharge wastewater directly or after simple treatment, which not only violates environmental protection regulations but also exacerbates environmental pollution problems. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this invention is to provide a treatment device and method for slaughterhouse wastewater. This invention highly integrates the slaughtering workbench, auxiliary support components, and wastewater treatment components onto a frame, forming an integrated treatment unit. This design significantly reduces the floor space required, allowing for easy installation and use even in small slaughterhouses. Because the slaughtering workbench and wastewater treatment components are adjacent, the time from wastewater generation to entering the treatment process is greatly shortened. This not only improves wastewater treatment efficiency but also helps reduce the accumulation and diffusion of pollutants in the wastewater, thereby enhancing the overall treatment effect. Through integrated design, this invention reduces the complex piping layout and connections in traditional wastewater treatment systems, simplifying the installation process and reducing construction difficulty. This invention significantly reduces pipe material and installation costs, while also minimizing the risk of pipe leaks and improving system stability and reliability. The integrated design simplifies maintenance and operation, with all key components concentrated on a rack for easy daily inspection and troubleshooting. Furthermore, optimized layout and configuration enhance operator safety and work efficiency. While reducing floor space and costs, this invention also prioritizes environmental protection and sustainability. By efficiently treating slaughterhouse wastewater, it reduces environmental pollutant emissions, meeting current environmental regulations. This design also provides an economically viable wastewater treatment solution for small slaughterhouses, contributing to the industry's green and sustainable development.

The scraper is vertically slidably connected to the bottom of the plate frame and a return spring is fixedly connected between it and the inner wall of the plate frame. The guide shaft is fixedly connected to the top of the scraper. One end of the guide shaft extends through the top of the plate frame and is slidably connected to the inner wall of the limiting groove opened at the bottom of the fixed plate frame.

[0013] Specifically, the depth of the limiting groove gradually increases from the end near the scum and sludge collection box to the end away from the scum and sludge collection box. The height of the end of the third processing chamber near the scum and sludge collection box is lower than the height of the end away from the scum and sludge collection box.

[0016] A method of using a slaughterhouse wastewater treatment device, applied to the above-described slaughterhouse wastewater treatment device, includes the following steps: S1: Start-up and synchronous operation: First, the controller sends a start command. After receiving the command, the synchronous drive feeding component starts to run, and at the same time drives the oil-water separation treatment component and the air flotation biological treatment component to start synchronously. S2: Slaughtering operation and wastewater collection: Slaughtering personnel open the retractable water tap and intermittent spray mechanism to prepare for slaughtering operations. During the slaughtering process, the wastewater generated flows automatically into the filter oil-water separation treatment component through the drainage design of the slaughtering workbench. S3: Wastewater Treatment and Chemical Dosing: Wastewater undergoes primary solid-liquid separation and oil-water separation within the filtration and oil-water separation treatment component. The separated solids are collected in a solids collection cylinder, the separated waste oil is collected in a waste oil collection cylinder, and the separated liquid is quantitatively delivered to the air flotation biological treatment component for secondary and tertiary solid-liquid separation. The secondary solid-liquid separation removes suspended solids, grease, and various colloidal substances from the water, while the tertiary solid-liquid separation removes suspended solids, bacteria, viruses, and other microorganisms from the wastewater, ensuring stable and high-quality effluent. During the secondary and tertiary solid-liquid separation processes within the air flotation biological treatment component, the synchronous drive feeding component simultaneously dispenses appropriate amounts of corresponding wastewater treatment chemicals. The scum produced during the secondary solid-liquid separation is transported to the scum sludge collection tank for collection. S4: Water Recycling and Sludge Treatment: After slaughtering, the treated water is pumped into the storage tank by a circulation pump for reuse in subsequent slaughtering operations. After a period of use, the sludge inside the air flotation biological treatment component is pumped into the scum collection tank by the first sludge pump. When the sludge in the scum collection tank reaches a certain amount, it is pumped into an external transport vehicle by the second sludge pump for further treatment or disposal.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention highly integrates the slaughtering workbench, auxiliary support components, and wastewater treatment components onto a frame, forming a unified processing unit. This design significantly reduces the floor space required, allowing for easy installation and use even in small slaughterhouses. Because the slaughtering workbench is adjacent to the wastewater treatment components, the time from wastewater generation to entry into the treatment process is greatly shortened. This not only improves wastewater treatment efficiency but also helps reduce the accumulation and spread of pollutants in the wastewater, thereby enhancing the overall treatment effect. Through this integrated design, this invention reduces the complex piping layout and connections in traditional wastewater treatment systems. This simplifies the installation process, reduces construction difficulty, and significantly reduces piping material and installation costs. Meanwhile, it reduces the risk of pipeline leakage and improves the stability and reliability of the system. The integrated design makes the maintenance and operation of the entire processing system simpler, with all key components concentrated on the rack for easy daily inspection and troubleshooting. In addition, through optimized layout and configuration, this invention also improves the safety and work efficiency of operators. While reducing the footprint and lowering costs, this invention also focuses on environmental protection and sustainability. By efficiently treating slaughterhouse wastewater, it reduces the emission of environmental pollutants, meeting the requirements of current environmental regulations. At the same time, this design also provides an economical and feasible wastewater treatment solution for small slaughterhouses, which helps to promote the green and sustainable development of the industry.

[0019] 2. The present invention also includes a filter oil-water separation treatment component. The filter oil-water separation treatment component can not only achieve initial fixed separation and oil-water separation, but also store excess sewage and release it at a set rate to stabilize its flow rate. This ensures the stable operation of subsequent treatment equipment and avoids low treatment efficiency caused by sudden changes in flow rate. After a short period of residence, the stored wastewater reaches a relatively uniform state, which helps to reduce water quality fluctuations during subsequent treatment and improve the overall treatment effect. 3. The present invention also includes an air flotation biological treatment component, which can perform secondary solid-liquid separation, tertiary solidification separation and sterilization on the liquid after oil-water separation. The secondary solid-liquid separation is used to remove suspended solids, oils and various colloidal substances in the water, and the tertiary solid-liquid separation and sterilization are used to remove suspended solids, bacteria, viruses and other microorganisms in the sewage, ensuring that the effluent water quality is stable and of high quality. 4. This invention also includes a synchronous transmission feeding component, which can precisely control the amount of reagent added, ensuring that the amount of reagent added each time is within a predetermined range. This helps maintain the chemical balance in the wastewater treatment process and improves the treatment effect. At the same time, since no manual addition is required, it greatly reduces the labor intensity of workers and reduces reagent waste, further reducing costs. Secondly, through the synchronous transmission mechanism, the feeding component can also operate synchronously with other key components. This synchronization ensures the coordination and efficiency of the entire wastewater treatment system. The single power source design also reduces production costs and is easier to control during use, reducing the difficulty of operation. 5. The present invention also includes a solar panel power supply component. Solar energy is free. Once the solar panel is installed and put into operation, it can continuously provide power to the equipment, effectively saving energy and avoiding the cost of purchasing electricity. On the other hand, the solar panel usually has a long service life and relatively low maintenance costs, which further reduces long-term production costs. 6. This invention also includes a water storage tank. The main function of the water storage tank is to store high-quality water that has been treated to meet usage standards. By storing this high-quality water, this invention ensures the sustainable use of water resources and avoids unnecessary waste. The stored high-quality water can be directly used in subsequent slaughtering operations, such as animal cleaning and equipment rinsing, thereby reducing the demand for fresh water. This recycling method not only simplifies the water resource management process but also improves the efficiency of slaughtering operations. After introducing the water storage tank, slaughterhouses can significantly reduce their dependence on external water sources, especially in water-scarce areas, where this advantage is particularly obvious. By recycling water resources, this invention helps alleviate the problem of water shortage and is also in line with the concept of sustainable development. Less use of fresh water means lower water bills, which is a significant cost saving for slaughterhouses. In addition, due to the existence of the water storage tank, slaughterhouses can also reduce fines or losses caused by poor water resource management, further reducing operating costs. 7. The present invention also includes a collection component that can efficiently collect various types of waste generated during the slaughtering process, including but not limited to solid waste, waste oil, scum, and sludge. This comprehensive collection method helps reduce waste pollution to the environment and also facilitates resource recycling. By centrally treating waste through the collection component, pollution of slaughter wastewater, exhaust gas, and solid waste to the environment can be effectively reduced. This not only helps protect the ecological environment around the slaughterhouse but also meets the requirements of current environmental protection policies. By reducing the accumulation and discharge of waste, it also helps maintain the cleanliness and hygiene of the slaughterhouse and reduces fines or losses caused by improper waste disposal.

Detailed Implementation

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0023] The following description, in conjunction with the accompanying drawings, describes an apparatus and method for treating slaughterhouse wastewater according to an embodiment of the present invention.

[0024] like Figures 1-9 As shown, an embodiment of the present invention provides a treatment device for slaughterhouse wastewater, comprising: Main unit frame 1: Set on the ground, with a first mounting slot 11 and a second mounting slot 12 respectively opened on its top, and a controller 13 is provided on its surface; Water storage tank 2: Installed in the first mounting slot 11, with a solar panel power supply component 21 on its top for powering the controller 13. A retractable faucet 22 and an intermittent spray mechanism 23 are symmetrically arranged on its surface and are connected to the inside of the water storage tank 2. Slaughtering component 3: includes a slaughtering workbench 31 and an auxiliary support assembly 32. The slaughtering workbench 31 is installed on the top of the second mounting slot 12, and the auxiliary support assembly 32 is installed on the water storage tank 2, the main frame 1 and the slaughtering workbench 31 respectively. Wastewater treatment component 4 includes a truncated pyramid frame 41, an oil-water separation and filtration component 42, a synchronous drive feeding component 43, and an air flotation biological treatment component 44. The truncated pyramid frame 41 is installed in the second mounting slot 12. The oil-water separation and filtration component 42, the synchronous drive feeding component 43, and the air flotation biological treatment component 44 are arranged vertically on the truncated pyramid frame 41. The synchronous drive feeding component 43 and the air flotation biological treatment component 44 are connected to the controller 13 via a bus system to transmit data and receive control commands. The top of the oil-water separation and filtration component 42 is connected to the bottom of the slaughtering workbench 31. The synchronous drive feeding component 43 is connected to both the oil-water separation and filtration component 42 and the air flotation biological treatment component 44. The air flotation biological treatment component 44 is connected to the water storage tank 2 via a water delivery hose. Collection component 5 includes a solid collection cylinder 51, a waste oil collection cylinder 52, and a scum and sludge collection box 53. The solid collection cylinder 51 and the waste oil collection cylinder 52 are respectively installed on the surface of the main frame 1 and connected to the oil-water separation treatment component 42. The scum and sludge collection box 53 is installed inside the main frame 1 and connected to the air flotation biological treatment component 44.

[0025] It should be noted that the solar panel power supply assembly 21 described in this embodiment includes a bracket, a solar panel, a transformer, and a battery. The solar panel, the transformer, and the battery are connected in sequence by wires. The battery is used to supply power to the controller 13. One end of the bracket extends out of the top of the water tank 2 and covers the slaughtering workbench 31. A fan and a light are also provided at the bottom of the end of the bracket that extends out of the top of the water tank 2. They are electrically connected to the controller 13, and the fan and the light are used for heat dissipation and lighting, respectively.

[0026] It should also be noted that the intermittent spray mechanism 23 includes a support, a spray pipe, a solenoid valve, and a high-pressure nozzle. The solenoid valve is electrically connected to the controller 13, and intermittent spraying is achieved by the solenoid valve opening and closing at timed intervals. The high-pressure nozzle is precisely installed facing the recessed part 313, and the strong water flow it sprays directly impacts the inner wall of the filter cylinder 426. This design aims to effectively assist solid matter in separating from the inner wall of the filter cylinder 426, thereby improving filtration efficiency and cleaning effect.

[0027] Understandably, the auxiliary support assembly 32 includes a cutting board, hooks, and a knife basket.

[0028] Specifically, this invention highly integrates the slaughtering workbench 31, auxiliary support assembly 32, and wastewater treatment assembly 4 onto a frame, forming an integrated processing unit. This design significantly reduces the floor space required, allowing for easy installation and use even in small slaughterhouses. Because the slaughtering workbench 31 is adjacent to the wastewater treatment assembly 4, the time from wastewater generation to entry into the treatment process is greatly shortened. This not only improves wastewater treatment efficiency but also helps reduce the accumulation and diffusion of pollutants in the wastewater, thereby enhancing the overall treatment effect. Through integrated design, this invention reduces the complex pipe layout and connections in traditional wastewater treatment systems. This not only simplifies the installation process and reduces construction difficulty but also significantly reduces pipe material and installation costs. Simultaneously, it reduces pipe leakage. This invention reduces the risk of leakage, improves system stability and reliability, and simplifies maintenance and operation by integrating the entire processing system. All key components are concentrated on the rack, facilitating daily inspections and troubleshooting. Furthermore, optimized layout and configuration enhance operator safety and work efficiency. While reducing floor space and costs, this invention also prioritizes environmental protection and sustainability. By efficiently treating slaughterhouse wastewater, it reduces environmental pollutant emissions, meeting current environmental regulations. This design also provides an economical and feasible wastewater treatment solution for small slaughterhouses, contributing to the industry's green and sustainable development. The invention also includes a filtration oil-water separation treatment component 42. This invention not only achieves primary solid-liquid separation and oil-water separation, but also stores excess wastewater, allowing it to be released at a set rate to stabilize the flow and ensure stable operation of subsequent treatment equipment. This avoids low treatment efficiency due to sudden flow changes. After a short period of residence, the stored wastewater reaches a relatively uniform state, which helps reduce water quality fluctuations during subsequent treatment and improves the overall treatment effect. The invention also includes an air flotation biological treatment component 44, which can perform secondary solid-liquid separation, tertiary solid-liquid separation, and sterilization on the liquid after oil-water separation. The secondary solid-liquid separation removes suspended solids, oils, and various colloidal substances from the water, while the tertiary solid-liquid separation and sterilization treatment... To remove suspended solids, bacteria, viruses, and other microorganisms from wastewater and ensure stable and high-quality effluent, this invention also includes a synchronous transmission feeding assembly 43. This assembly precisely controls the dosage of the reagent, ensuring that each dose is within a predetermined range. This helps maintain the chemical balance during wastewater treatment, improving treatment efficiency. Furthermore, since manual feeding is eliminated, it significantly reduces labor intensity and reagent waste, further lowering costs. Secondly, through the synchronous transmission mechanism, the synchronous transmission feeding assembly 43 can operate synchronously with other key components. This synchronization ensures the coordination and efficiency of the entire wastewater treatment system. The single power source design also correspondingly reduces production costs.The invention is easy to control and reduces operational difficulty. It also includes a solar panel power supply component 21. Solar energy is free; once installed and operational, it continuously provides power to the equipment, effectively saving energy and avoiding the cost of purchasing electricity. Furthermore, solar panels typically have a long lifespan and relatively low maintenance costs, further reducing long-term production costs. The invention also includes a water storage tank 2. The main function of the water storage tank 2 is to store high-quality water that has been treated to meet usage standards. By storing this high-quality water, the invention ensures the sustainable use of water resources and avoids unnecessary waste. The stored high-quality water can be directly used in subsequent slaughtering operations, such as animal cleaning and equipment rinsing, thereby reducing the demand for fresh water. This recycling method not only simplifies water resource management but also improves the efficiency of slaughtering operations. With the introduction of the water storage tank 2, slaughterhouses can significantly reduce their dependence on external water sources, especially in water-scarce areas, where this advantage is particularly pronounced. By utilizing water resources, this invention helps alleviate water shortages and aligns with the concept of sustainable development. Reduced use of fresh water means lower water bills, resulting in significant cost savings for slaughterhouses. Furthermore, the presence of the water storage tank 2 reduces fines and losses due to poor water management, further lowering operating costs. The invention also includes a collection component 5, which efficiently collects various wastes generated during the slaughtering process, including but not limited to solid waste, waste oil, scum, and sludge. This comprehensive collection method helps reduce waste pollution and promotes resource recycling. Centralized waste treatment via the collection component 5 effectively reduces pollution from slaughterhouse wastewater, exhaust gas, and solid waste. This not only helps protect the surrounding environment but also complies with current environmental policies. Reducing waste accumulation and discharge also helps maintain cleanliness and hygiene at the slaughterhouse, minimizing fines and losses due to improper waste disposal.

[0029] In practical use, firstly, the controller 13 sends a start command. Upon receiving the command, the synchronous transmission feeding component 43 starts operating, simultaneously driving the oil-water separation treatment component 42 and the air flotation biological treatment component 44 to start synchronously. Slaughterers open the retractable faucet 22 and the intermittent spray mechanism 23 to prepare for slaughtering operations. During the slaughtering process, the wastewater generated flows automatically into the oil-water separation treatment component 42 through the drainage design of the slaughtering workbench 31. Inside the oil-water separation treatment component 42, the wastewater undergoes primary solid-liquid separation and oil-water separation. The separated solids are transported to the solids collection cylinder 51 for collection, the separated waste oil is transported to the waste oil collection cylinder 52 for collection, and the separated liquid is quantitatively transported to the air flotation biological treatment component 44 for secondary and tertiary solid-liquid separation. Used to remove suspended solids, grease, and various colloidal substances from water, the three-stage solid-liquid separation removes suspended solids, bacteria, viruses, and other microorganisms from wastewater, ensuring stable and high-quality effluent. During the secondary and tertiary solid-liquid separation processes of the air flotation biological treatment component 44, the synchronous drive feeding component 43 simultaneously adds appropriate amounts of wastewater treatment agents. The scum produced during the secondary solid-liquid separation is transported to the scum and sludge collection tank 53 for collection. After slaughter, the treated water is pumped to the storage tank 2 by the circulation pump 4413 for subsequent slaughter operations. After a period of use, the sludge inside the air flotation biological treatment component 44 is pumped to the scum and sludge collection tank 53 by the first sludge pump 531. When the sludge in the scum and sludge collection tank 53 reaches a certain amount, it is pumped to an external transport vehicle by the second sludge pump 532 for further treatment or disposal.

[0030] In one embodiment of the present invention, such as Figure 3 As shown, the slaughtering workbench 31 includes a work surface 310, which is fixedly connected to the top of the second mounting groove 12. A water trough 311 is provided on the top of the work surface 310. A partition 312 is provided in the middle of the water trough 311. Recesses 313 are provided at both ends of the water trough 311 and are connected to the inside of the water trough 311. The top of the oil-water separation treatment component 42 is connected to the bottom of the recesses 313.

[0031] Specifically, the structure and connection relationship of the slaughtering workbench 31 will be further explained. This invention ingeniously integrates the slaughtering workbench 31 directly into the wastewater treatment equipment. This innovative design not only significantly reduces the floor space occupied but also greatly shortens the time from wastewater generation to treatment. Simultaneously, by reducing the use of pipes, production costs are further reduced. The slaughtering workbench 31 consists of a tabletop 310, which is securely installed on top of the second mounting slot 12. A water trough 311 is designed above the tabletop 310 to guide water flow. A partition 312 is cleverly placed in the middle of the water trough 311. To achieve effective separation of water flow, the water tank 311 is divided into two workstations by a partition 312, allowing two people to operate simultaneously without interfering with each other, thus effectively improving slaughtering efficiency. The two ends of the water tank 311 are respectively provided with recesses 313, which are interconnected with the interior of the water tank 311 to ensure smooth water flow. It is particularly worth mentioning that the top of the oil-water separation treatment component 42 is cleverly connected to the bottom of the recesses 313, allowing wastewater to directly enter the interior of the oil-water separation treatment component 42 through the recesses 313, accelerating wastewater treatment efficiency and reducing the corresponding pipeline usage costs.

[0032] In one embodiment of the present invention, such as Figure 4 As shown, the oil-water separation treatment assembly 42 includes a separator frame 421, a first separation chamber 422, a second separation chamber 423, a third separation chamber 424, a liquid storage chamber 425, a filter cylinder 426, a first spiral auger 427, an oil drain pipe 428, an oil drain valve 429, and a quantitative liquid draining roller 4210. The separator frame 421 is fixedly connected to the top of the truncated pyramid frame 41. The first separation chamber 422, the second separation chamber 423, the third separation chamber 424, and the liquid storage chamber 425 are symmetrically arranged from the outside to the inside on the top of the separator frame 421 and are connected to each other. The filter cylinder 426 is symmetrically fixedly connected to the top of the separator frame 421 and is located on one side of the top of the first separation chamber 422. The top of the filter cylinder 426 is connected to the top of the first separation chamber 422. The bottom of the recessed part 313 corresponds to and is connected to it. One end of the filter cylinder 426 extends through the outside of the main frame 1 and is connected to the inside of the solid collection cylinder 51. The first spiral auger 427 is rotatably connected to the inner wall of the filter cylinder 426 and is connected to the synchronous transmission feeding assembly 43. One end of the oil drain pipe 428 is connected to the inside of the second separation chamber 423 and the third separation chamber 424 respectively. The other end of the oil drain pipe 428 extends through the outside of the main frame 1 and is connected to the inside of the waste oil collection cylinder 52. The oil drain valve 429 is set on the surface of the end of the oil drain pipe 428 that extends through the outside of the main frame 1. The quantitative liquid discharge roller 4210 is rotatably connected to the bottom of the liquid storage chamber 425 and is connected to the synchronous transmission feeding assembly 43.

[0033] It should be noted that the first separation chamber 422, the second separation chamber 423, and the third separation chamber 424 described in this embodiment are used to achieve three-stage oil-water separation, and the storage chamber 425 is used to regulate the amount and quality of wastewater to achieve a stable state. By setting up the storage chamber 425, excess wastewater can be stored and released at a set rate to stabilize its flow rate, thereby ensuring the stable operation of subsequent treatment equipment and avoiding low treatment efficiency caused by sudden changes in flow rate. The storage chamber 425 can also mix wastewater of different concentrations and masses to achieve a relatively uniform state, which helps to reduce water quality fluctuations during subsequent treatment and improve the overall treatment effect.

[0034] It should also be noted that the filter cylinder 426 described in this embodiment is a single-opening design. The opening of the filter cylinder 426 is connected to the interior of the solid collection cylinder 51. The bottom of the filter cylinder 426 is provided with filter holes. The shape of the first spiral auger 427 is adapted to the internal dimensions of the filter cylinder 426. The liquid entering the filter cylinder 426 is discharged into the first separation chamber 422 through the filter holes. The solids entering the filter cylinder 426 are pushed into the solid collection cylinder 51 by the first spiral auger 427. In order to prevent too much liquid from entering the solid collection cylinder 51, the filter cylinder 426 and the first spiral auger 427 can be tilted at a preset angle to prevent too much liquid from entering the solid collection cylinder 51 by the first spiral auger 427.

[0035] Understandably, a U-shaped groove is provided on the surface of the main frame 1 to facilitate the installation of the filter cartridge 426.

[0036] It is also understandable that, in order to facilitate the precise docking of the solid collection cylinder 51 and the waste oil collection cylinder 52 with the filter cylinder 426 and the oil drain pipe 428, a base platform is provided at the bottom of the main frame 1. A guide groove is provided on the base platform. The rollers at the bottom of the solid collection cylinder 51 and the waste oil collection cylinder 52 enter the guide groove and can be precisely docked with the filter cylinder 426 and the oil drain pipe 428. In order to prevent the solid collection cylinder 51 and the waste oil collection cylinder 52 from moving, an elastic clip is provided on the surface of the main frame 1. The elastic clip is engaged and fixed with the clip ring on the surface of the solid collection cylinder 51 and the waste oil collection cylinder 52, so that the position of the solid collection cylinder 51 and the waste oil collection cylinder 52 can be fixed.

[0037] It is also understandable that the bottom of the liquid storage chamber 425 is designed in a conical shape. This design cleverly solves several problems. First, the conical bottom facilitates the smooth discharge of liquid. Due to the angle of the cone, the liquid can flow more easily to the position of the metering discharge roller 4210 under the action of gravity, thereby achieving effective liquid discharge. Second, the conical design also takes into account the treatment of sediment. During the liquid storage process, some solid particles or sediments may be generated and deposited at the bottom of the chamber. The traditional flat bottom design may cause these sediments to gradually accumulate, thereby occupying valuable liquid storage space and even affecting the normal operation of the equipment. The conical bottom can guide these sediments to the position of the metering discharge roller 4210 and be discharged together with the liquid, thereby avoiding the accumulation of sediments inside the liquid storage chamber 425.

[0038] Specifically, the structure and connection relationship of the oil-water separation treatment component 42 will be further explained. The oil-water separation treatment component 42 is mainly used for the initial solid-liquid separation and oil-water separation of waste liquid, and to store the separated liquid. Finally, it is discharged at a set speed to ensure the stability of subsequent sewage treatment.

[0039] In practical use, the wastewater inside the recessed portion 313 flows directly into the filter cylinder 426. The liquid entering the filter cylinder 426 is discharged into the first separation chamber 422 through the filter holes. The solids entering the filter cylinder 426 are pushed into the solid collection cylinder 51 by the first auger 427, achieving initial solid-liquid separation. Then, the mixed liquid inside the first separation chamber 422 enters the second separation chamber 423 from the bottom of the first separation chamber 422. After the flow rate is reduced by the baffle plate, it then enters the third separation chamber 424 from the bottom of the second separation chamber 423. After the flow rate is reduced by the baffle plate, it finally enters the storage chamber 425 from the third separation chamber 424. Due to the difference in density between oil and water, the waste oil floats above the water during the flow process and remains in the second and third separation chambers 423 and 424. When the waste oil level corresponds to the height of the drain pipe 428, the waste oil is directly discharged from the drain pipe 428 into the waste oil collection cylinder 52 for collection. A drain valve 429 is provided at the end of the drain pipe 428 that extends outside the main frame 1. This valve can be closed when cleaning the waste oil collection cylinder 52 to prevent waste oil from continuing to flow into the cleaning waste oil collection cylinder 52. The liquid after oil-water separation enters the storage chamber 425 for unified storage. The liquid inside the storage chamber 425 will reach a relatively uniform state after staying for a period of time. This helps to reduce water quality fluctuations in subsequent treatment processes and improve the overall treatment effect. A quantitative discharge roller 4210 is provided at the bottom of the storage chamber 425. When the quantitative discharge roller 4210 rotates, it can quantitatively discharge the waste liquid. By quantitatively discharging the liquid, the flow rate is stabilized to ensure the stability of subsequent sewage treatment.

[0040] In one embodiment of the present invention, such as Figure 5 As shown, the air flotation biological treatment component 44 includes a treatment frame 441, a first treatment chamber 442, a second treatment chamber 443, a third treatment chamber 444, a fourth treatment chamber 445, a fifth treatment chamber 446, and a sixth treatment chamber 447. The treatment frame 441 is symmetrically and oppositely fixed to the surface of the truncated pyramid frame 41 and is located on one side of the bottom of the synchronous transmission feeding component 43. The first treatment chamber 442, the second treatment chamber 443, the third treatment chamber 444, the fourth treatment chamber 445, the fifth treatment chamber 446, and the sixth treatment chamber 447 are sequentially opened from the inside to the outside on the top of the treatment frame 441 and are connected. The inner wall of the first treatment chamber 442 is provided with a horizontal stirring mechanism 448, which is connected to the synchronous transmission feeding component 447. The second and fifth treatment chambers 443 and 446 are connected in three phases. The bottom walls of the second and fifth treatment chambers 443 and 446 are respectively equipped with aeration mechanisms, which are connected to the air pump 4410 installed on the surface of the truncated frame 41 through the air guide pipe 449. The inner wall of the fifth treatment chamber 446 is equipped with an MBR membrane module 4411, which is located on the top side of the aeration mechanism. The MBR membrane module 4411 uses the water pump 4412 and water delivery hose installed on the truncated frame 41 to efficiently pump the treated water inside the MBR membrane module 4411 to the sixth treatment chamber 447. Then, the water in the sixth treatment chamber 447 is successfully pumped to the water storage tank 2 for storage through the circulation pump 4413 and water delivery hose also installed on the truncated frame 41. Among them, the air pump 4410, the water pump 4412 and the circulating pump 4413 are connected to the controller 13 through a bus system to realize data transmission and control command reception.

[0041] It should be noted that the first processing chamber 442, the second processing chamber 443 and the third processing chamber 444 described in this embodiment are used for air flotation treatment, the fourth processing chamber 445 and the fifth processing chamber 446 are used for MBR treatment, and the sixth processing chamber 447 is used for sterilization and disinfection treatment.

[0042] Specifically, the structure and connection relationship of the air flotation biological treatment component 44 are further explained. The air flotation biological treatment component 44 can perform secondary solid-liquid separation, tertiary solidification separation and sterilization treatment on the liquid after oil-water separation. The secondary solid-liquid separation is used to remove suspended solids, oils and various colloidal substances in the water. The tertiary solid-liquid separation and sterilization treatment are used to remove suspended solids, bacteria, viruses and other microorganisms in the sewage, ensuring that the effluent water quality is stable and of high quality.

[0043] In practical use, the liquid discharged by the metering discharge roller 4210 falls directly into the first treatment chamber 442. The first treatment chamber 442 is equipped with a horizontal stirring mechanism 448. During the operation of the horizontal stirring mechanism 448, the corresponding material cylinder 436 in the synchronous transmission feeding assembly 43 is simultaneously added with appropriate amounts of wastewater treatment agents. The wastewater treatment agents corresponding to the first treatment chamber 442 are flocculants, acids, or alkalis. The flocculant reacts with the waste liquid after being stirred by the horizontal stirring mechanism 448, forming flocculents. The acid or alkali is used to adjust the pH value of the waste liquid. Then, the liquid passes through the first... The waste liquid enters the second treatment chamber 443 from the bottom of the first treatment chamber 442. An aeration mechanism is installed on the bottom wall of the second treatment chamber 443, releasing air in the form of numerous microbubbles. These microbubbles quickly adhere to the particles, emulsified oil, and flocs that have undergone coagulation in the water. The waste liquid is then transported to the third treatment chamber 444. Due to the adhesion of the bubbles, the overall specific gravity of these particles or flocs becomes less than that of water, thus forcing them to rise rapidly to the surface. At this time, the scum scraping mechanism 4310 in the synchronous drive feeding assembly 43, corresponding to the position in the third treatment chamber 444, simultaneously scrapes the scum that has risen to the surface. Sludge is collected inside the sludge collection tank 53. This step removes suspended solids, grease, and various colloidal substances from the water. The wastewater then enters the fourth treatment chamber 445. Simultaneously, the feed cylinder 436 in the synchronous drive feeding assembly 43, corresponding to the position in the fourth treatment chamber 445, dispenses an appropriate amount of wastewater treatment agent. The wastewater treatment agent corresponding to the fourth treatment chamber 445 is activated sludge. After the activated sludge is mixed with the wastewater, it is transported to the fifth treatment chamber 446. The fifth treatment chamber 446 is equipped with an aeration mechanism and an MBR membrane module 4411. Through the cooperation of the aeration mechanism and the MBR membrane module 4411, suspended solids, grease, and various colloidal substances in the wastewater are removed. Suspended solids, bacteria, viruses, and other microorganisms are removed. Then, the water inside the MBR membrane module 4411 is pumped to the sixth treatment chamber 447 through the cooperation of the water pump 4412 and the water delivery hose. At the same time, the appropriate amount of wastewater treatment agent is simultaneously added to the feed cylinder 436 in the synchronous drive feeding component 43, which corresponds to the position of the sixth treatment chamber 447. The wastewater treatment agent corresponding to the sixth treatment chamber 447 is bleaching powder. The water treated with bleaching powder has been purified into high-quality water that can be recycled. Then, the water in the sixth treatment chamber 447 is successfully pumped to the water storage tank 2 for storage through the cooperation of the circulation pump 4413 and the water delivery hose.

[0044] In one embodiment of the present invention, such as Figure 6As shown, the synchronous transmission feeding assembly 43 includes a fixed plate frame 431, an upper reciprocating screw 432, a lower transmission rod 433, a synchronous gear 434, a toothed slide block 435, a material cylinder 436, a gear ring 437, a second spiral auger 438, a first transmission bevel gear 439, a scraping mechanism 4310, a second transmission bevel gear 4311, and a synchronous drive mechanism 4312. The fixed plate frame 431 is symmetrically fixedly connected to the surface of the zigzag frame 41 and is located on one side of the top of the processing frame 441. The upper reciprocating screw 432 and the lower transmission rod 433 rotate respectively. The upper reciprocating screw 432 and the lower transmission rod 433 are connected to the top and bottom of the fixed plate frame 431. Synchronous gears 434 are respectively installed at corresponding positions on the surface of the upper reciprocating screw 432 and the surface of the lower transmission rod 433, and they mesh with each other. A toothed slide block 435 is threaded to the outer surface of the upper reciprocating screw 432 and horizontally slidably connected to the top of the fixed plate frame 431. Three sets of material cylinders 436 are provided, each fixedly connected to the top of the fixed plate frame 431 and located on one side of the upper reciprocating screw 432. The bottoms of the three sets of material cylinders 436 extend through the fixed plate frame 431. The bottom of the cylinder 436 is aligned with the positions of the first processing chamber 442, the fourth processing chamber 445, and the sixth processing chamber 447. A gear ring 437 is rotatably connected to the inner wall of the cylinder 436 and meshes with the teeth on the surface of the toothed slide block 435. A second auger 438 is fixedly connected to the surface of the gear ring 437 and located inside the cylinder 436. A scraping mechanism 4310 is located at the bottom of the fixed plate frame 431 and corresponds to the position of the third processing chamber 444. One end of the scraping mechanism 4310 is fixedly connected to the first transmission bevel tooth on the surface of the lower transmission rod 433. The gears 439 mesh with each other, and the second transmission bevel gear 4311 is fixedly connected to one end of the upper reciprocating screw 432. The synchronous drive mechanism 4312 is set on the inner wall of the main frame 1. The synchronous drive mechanism 4312 is connected to one end of the central shaft of the first spiral auger 427, one end of the central shaft of the quantitative discharge roller 4210, one end of the central shaft of the horizontal stirring mechanism 448, and the second transmission bevel gear 4311. The synchronous drive mechanism 4312 is connected to the controller 13 through the bus system to realize data transmission and control command reception.

[0045] Specifically, the structure and connection relationship of the synchronous transmission feeding component 43 will be further explained. The synchronous transmission feeding component 43 can accurately control the amount of agent added, ensuring that the agent added each time is within the predetermined range. This helps to maintain the chemical balance in the sewage treatment process and improve the treatment effect. At the same time, since no manual addition is required, it greatly reduces the labor intensity of workers and reduces the waste of agents, further reducing costs. Secondly, through the synchronous transmission mechanism, the feeding component can also achieve synchronous operation with other key components. This synchronization ensures the coordination and efficiency of the entire sewage treatment system. The design of a single power source also reduces production costs and is easier to control during use, reducing the difficulty of operation.

[0046] In practical use, the synchronous drive mechanism 4312 operates according to instructions, synchronously driving the first spiral auger 427, the quantitative discharge roller 4210, and the horizontal stirring mechanism 448 to rotate. The rotation of the first spiral auger 427 achieves solid conveying, the rotation of the quantitative discharge roller 4210 achieves quantitative liquid discharge, and the horizontal stirring mechanism 448 achieves mixing. The synchronous drive mechanism 4312 also synchronously drives the second transmission bevel gear 4311 to rotate, which in turn synchronously drives the upper reciprocating screw 432 to rotate. The rotation of the upper reciprocating screw 432, through the synchronous gear 434, synchronously drives the lower... As the transmission rod 433 rotates and the upper reciprocating screw 432 rotates, the toothed slide 435 moves horizontally back and forth and contacts and meshes with the toothed rings 437 on the three sets of material cylinders 436. It also drives the toothed rings 437 to rotate synchronously. The rotation of the toothed rings 437 synchronously drives the second spiral auger 438 to rotate synchronously. The rotation of the second spiral auger 438 synchronously realizes the discharge of the agent. The rotation of the lower transmission rod 433 synchronously drives the first transmission bevel gear 439 to rotate synchronously. The rotation of the first transmission bevel gear 439 synchronously drives the slag scraping mechanism 4310 to operate. The operation of the slag scraping mechanism 4310 scrapes the scum in the third processing chamber 444 into the scum and sludge collection box 53 for collection.

[0047] In one embodiment of the present invention, such as Figure 7 As shown, the slag scraping mechanism 4310 includes a scraper 43101, a lower reciprocating screw 43102, a driven bevel gear 43103, a plate frame 43104, a scraper 43105, a guide shaft 43106, and a limiting groove 43107. The scraper 43101 is fixedly connected to the bottom of the fixed plate frame 431 and corresponds to the position of the third processing chamber 444. The lower reciprocating screw 43102 is rotatably connected to the inner wall of the plate frame 43104. One end of the lower reciprocating screw 43102 extends through the outside of the plate frame 43104 and is fixedly connected to the driven bevel gear 43103. 43103 meshes with the first transmission bevel gear 439. The plate frame 43104 is threaded to the outer surface of the lower reciprocating screw 43102 and is horizontally slidably connected to the inner wall of the scraper 43101. The scraper 43105 is vertically slidably connected to the bottom of the plate frame 43104 and a return spring is fixedly connected between it and the inner wall of the plate frame 43104. The guide shaft 43106 is fixedly connected to the top of the scraper 43105. One end of the guide shaft 43106 passes through the top of the plate frame 43104 and is slidably connected to the inner wall of the limiting groove 43107 opened at the bottom of the fixed plate frame 431.

[0048] Specifically, the structure and connection relationship of the scum scraping mechanism 4310 are further explained. The scum scraping mechanism 4310 is used to scrape the scum in the third processing chamber 444 into the scum and sludge collection box 53 for collection. In use, the first transmission bevel gear 439 rotates synchronously, driving the passive bevel gear 43103 and the lower reciprocating screw 43102 to rotate. The rotation of the lower reciprocating screw 43102 synchronously drives the plate frame 43104 to move horizontally and reciprocally. During the movement of the plate frame 43104, the scraper 43105 and the guide shaft 43106 move synchronously. During the movement, the guide shaft 43106 is squeezed by the inner wall of the limiting groove 43107, and its height changes, which synchronously drives the height of the scraper 43105 to change. During the movement, the scraper 43105 contacts the scum and synchronously scrapes the scum into the scum and sludge collection box 53 for collection.

[0049] In one embodiment of the present invention, such as Figure 7 As shown, the depth of the limiting groove 43107 gradually increases from the end near the scum and sludge collection box 53 to the end away from the scum and sludge collection box 53. The height of the end of the third processing chamber 444 near the scum and sludge collection box 53 is lower than the height of the end away from the scum and sludge collection box 53. A guide plate is provided on the surface of the end of the third processing chamber 444 near the scum and sludge collection box 53. The guide plate is used to transport the scum inside the third processing chamber 444 to the inside of the scum and sludge collection box 53.

[0050] Specifically, the limiting groove 43107 is further limited. The depth of the limiting groove 43107 gradually increases from the end near the scum and sludge collection box 53 to the end away from the scum and sludge collection box 53. This helps the scraper 43105 to decrease in height and contact the scum as it moves towards the scum and sludge collection box 53, and push the scum into the scum and sludge collection box 53. The height of the end of the third processing chamber 444 near the scum and sludge collection box 53 is lower than the height of the end away from the scum and sludge collection box 53. This helps the scum to flow easily towards the scum and sludge collection box 53. The function of the guide plate is to further guide the flow direction of the scum and ensure that the scum can smoothly enter the scum and sludge collection box 53.

[0051] In one embodiment of the present invention, such as Figure 8As shown, the synchronous drive mechanism 4312 includes a gear carrier 43121, a drive motor 43122, a transmission gear 43123, a synchronous toothed belt 43124, and a side bevel gear 43125. The gear carrier 43121 is rotatably connected to the inner wall of the main frame 1, and the drive motor 43122 is fixedly connected to the inner wall of the main frame 1 and fixedly connected to one end of the gear carrier 43121. The drive motor 43122 is connected to the controller 13 through a bus system to realize data transmission and control command reception. One end of the central shaft of the spiral auger 427, one end of the central shaft of the metering discharge roller 4210, and one end of the central shaft of the horizontal stirring mechanism 448 respectively penetrate into the interior of the main frame 1 and are fixedly connected to the transmission gear 43123. Multiple sets of transmission gears 43123 are respectively connected to the fixed gear on the gear frame 43121 through the synchronous toothed belt 43124. Among them, the surface of the central shaft of the metering discharge roller 4210 is fixedly connected to the side bevel gear 43125, which meshes with the second transmission bevel gear 4311.

[0052] Specifically, the structure and connection relationship of the synchronous drive mechanism 4312 will be further explained. The synchronous drive mechanism 4312 is used to synchronously drive other key components to achieve synchronous operation. This synchronicity ensures the coordination and efficiency of the entire sewage treatment system. In use, the drive motor 43122 runs according to the command. The operation of the drive motor 43122 synchronously drives the gear frame 43121 to rotate. The rotation of the gear frame 43121 synchronously drives the transmission gear 43123 to rotate through the synchronous toothed belt 43124. The rotation of the transmission gear 43123 drives the first spiral auger 427, the quantitative discharge roller 4210 and the horizontal stirring mechanism 448 to rotate respectively. A side bevel gear 43125 is provided on the central shaft of the quantitative discharge roller 4210. The rotation of the side bevel gear 43125 also synchronously drives the second transmission bevel gear 4311 to rotate.

[0053] In one embodiment of the present invention, such as Figure 9 As shown, the scum and sludge collection box 53 also includes a first sludge pump 531 and a second sludge pump 532. The first sludge pump 531 and the second sludge pump 532 are respectively fixedly connected to the surface of the scum and sludge collection box 53. The first sludge pump 531 and the second sludge pump 532 are respectively connected to the controller 13 through a bus system to realize data transmission and control command reception. The first sludge pump 531 is used to pump the sludge at the bottom of the fifth processing chamber 446 into the scum and sludge collection box 53. The second sludge pump 532 is used to pump the sludge inside the scum and sludge collection box 53 into the external transport vehicle.

[0054] Specifically, by integrating the first sludge pump 531 and the second sludge pump 532, effective management and transportation of sludge are achieved. The first sludge pump 531 is used to pump the sludge at the bottom of the fifth treatment chamber 446 into the scum and sludge collection box 53 to ensure that the sludge can be centrally treated. The second sludge pump 532 is used to pump the sludge inside the scum and sludge collection box 53 into an external transport vehicle. This achieves effective transfer of sludge from the treatment system to the final disposal site.

[0055] A method of using a slaughterhouse wastewater treatment device, applied to the above-mentioned slaughterhouse wastewater treatment device, includes the following steps: S1: Start-up and synchronous operation: First, the controller 13 sends a start command. After receiving the command, the synchronous transmission feeding component 43 starts to run, and at the same time drives the oil-water separation treatment component 42 and the air flotation biological treatment component 44 to start synchronously. S2: Slaughtering operation and wastewater collection: Slaughtering personnel open the retractable water tap 22 and intermittent spray mechanism 23 to prepare for slaughtering operation. During the slaughtering process, the wastewater generated flows into the filter oil-water separation treatment component 42 automatically through the diversion design of the slaughtering workbench 31. S3: Wastewater Treatment and Chemical Dosing: Wastewater undergoes primary solid-liquid separation and oil-water separation within the filtration oil-water separation treatment component 42. The separated solids are transported to the solids collection cylinder 51 for collection, the separated waste oil is transported to the waste oil collection cylinder 52 for collection, and the separated liquid is quantitatively transported to the air flotation biological treatment component 44 for secondary and tertiary solid-liquid separation. The secondary solid-liquid separation is used to remove suspended solids, grease, and various colloidal substances from the water, while the tertiary solid-liquid separation is used to remove suspended solids, bacteria, viruses, and other microorganisms from the wastewater, ensuring stable and high-quality effluent. During the secondary and tertiary solid-liquid separation processes in the air flotation biological treatment component 44, the synchronous drive feeding component 43 simultaneously adds appropriate amounts of corresponding wastewater treatment chemicals. The scum generated during the secondary solid-liquid separation is transported to the scum sludge collection box 53 for collection. S4: Water Recycling and Sludge Treatment: After slaughtering, the treated water is pumped into the water storage tank 2 by the circulation pump 4413 for recycling in subsequent slaughtering operations. After a period of use, the sludge inside the air flotation biological treatment component 44 is pumped into the scum and sludge collection tank 53 by the first sludge pump 531. When the sludge in the scum and sludge collection tank 53 reaches a certain amount, it is pumped into an external transport vehicle by the second sludge pump 532 for further treatment or disposal.

[0056] In summary, the slaughterhouse wastewater treatment device and method of this invention integrates the slaughtering workbench 31, auxiliary support assembly 32, and wastewater treatment assembly 4 onto a frame, forming an integrated treatment unit. This design significantly reduces the floor space required, making it easy to install and use even in small slaughterhouses. Because the slaughtering workbench 31 is adjacent to the wastewater treatment assembly 4, the time from wastewater generation to entering the treatment process is greatly shortened. This not only improves wastewater treatment efficiency but also helps reduce the accumulation and diffusion of pollutants in the wastewater, thereby enhancing the overall treatment effect. Through the integrated design, this invention reduces the complex pipe layout and connections in traditional wastewater treatment systems. This simplifies the installation process, reduces construction difficulty, and significantly reduces pipe materials and installation costs. Simultaneously, it reduces the risk of pipe leakage and improves system stability and reliability. The integrated design makes the maintenance and operation of the entire treatment system simpler, as all key components are concentrated on the frame, facilitating daily inspection and troubleshooting. Furthermore, through optimized layout and configuration, this invention also improves operator safety and work efficiency. While reducing floor space and costs, this invention also emphasizes environmental protection and sustainability. By efficiently treating slaughterhouse wastewater, the emission of environmental pollutants is reduced, meeting current environmental regulations. At the same time, this design provides an economical and feasible wastewater treatment solution for small-scale slaughterhouses, contributing to the industry's green and sustainable development.
