Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a biological enzyme-based in-situ sludge reduction device that replaces traditional carbon sources. Background Technology

[0002] With the acceleration of urbanization and the expansion of wastewater treatment scale, the output of sludge, a byproduct of wastewater treatment, is increasing year by year. Sludge is rich in pollutants such as organic matter, heavy metals, and pathogens. Improper disposal can easily lead to secondary pollution. Therefore, sludge reduction has become one of the core research topics in the environmental protection field. Compared with off-site disposal methods such as sludge transportation for incineration and landfill, in-situ sludge reduction technology has become the mainstream direction of current industry development due to its advantages such as small footprint, low energy consumption, and short process. Its core principle is to achieve sludge degradation and reduction within the wastewater treatment system through biological, chemical, or physical means, thereby reducing the final disposal volume.

[0003] However, existing in-situ sludge reduction technologies that use bio-enzymes to replace traditional carbon sources still face key technical bottlenecks: poor synergy between bio-enzymes and sludge, and insufficient precision in dosing, resulting in low enzyme utilization and difficulty in fully realizing their catalytic efficiency. Specifically, existing devices mostly use simple stirring paddles for mixing, resulting in a single stirring trajectory and the formation of dead zones on the inner wall and bottom of the reaction vessel, preventing some sludge from fully contacting the bio-enzymes. Simultaneously, enzyme dosing is often done via gravity feeding or fixed-rate pumping, lacking a dynamic matching mechanism with sludge concentration and reaction progress. When sludge viscosity or treatment volume fluctuates, over-dosing can lead to waste, while under-dosing can result in poor reduction effects. These shortcomings make the treatment efficiency of existing bio-enzyme reduction technologies unstable, enzyme costs high, and unable to effectively replace traditional carbon sources for efficient and economical in-situ sludge reduction, thus hindering the industrial application of this technology. Summary of the Invention

[0004] The purpose of this invention is to provide a bio-enzyme-based sludge reduction device that replaces traditional carbon sources, in order to solve the problems of poor synergy between bio-enzymes and sludge, insufficient dosing precision leading to low enzyme utilization, unstable treatment efficiency, and high enzyme consumption costs in existing bio-enzyme-based sludge reduction technologies that replace traditional carbon sources, thus failing to effectively achieve efficient and economical in-situ sludge reduction.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bio-enzyme replacement device for in-situ sludge reduction using traditional carbon sources, comprising a composite enzyme catalytic reaction vessel, an enzyme preparation storage and control tank, a metering and dosing module, and a composite stirring reaction unit; the composite enzyme catalytic reaction vessel is the core reaction carrier of the device, with sturdy support feet welded around its lower surface, a liquid level groove in the center of its outer surface, an inner tank in the center of its interior, a protective box connected to the center of its bottom end, a sludge-enzyme mixture output main pipe connected to one side of its bottom end, the enzyme preparation storage and control tank installed on one side of its upper surface, an adaptive air pump installed in the center of its upper end, and a process water injection pipe connected to one side of its upper end; an intelligent process control terminal is installed on the surface of the enzyme preparation storage and control tank, and an enzyme injection pipe extending into the interior of the enzyme preparation storage and control tank is connected to its upper end; the metering and dosing module is located at the lower end of the sludge-enzyme mixture output main pipe; the composite stirring reaction unit is located in the center of the inner tank.

[0007] Preferably, the lower support block has mounting grooves on all four sides of its surface, and each mounting groove has a connecting rod embedded inside it; the upper ends of the four mounting plates are movably connected to the lower ends of the support rods, and the lower ends of the four mounting plates are movably connected to the upper ends of the connecting rods.

[0008] Preferably, a connecting rod is fixedly connected to the lower surface of the lower support block. The lower end of the connecting rod extends out of the lower outer end of the composite enzyme catalytic reaction vessel and into the center of the protective box. A driven gear plate is fixedly installed on the surface of the connecting rod. A lead screw is rotatably provided on one side of the inside of the protective box. The outer end of the lead screw meshes with the driven gear plate to form a transmission engagement. One end of the lead screw extends out of the outer end of the protective box and is correspondingly connected to a high-speed shearing motor.

[0009] Preferably, each of the four mounting plates has a guide rail at the center of its front surface. Each guide rail is equipped with a flexible bionic sludge-removing scraper, and the flexible bionic sludge-removing scraper is fixed to the guide rail by bolts. The flexible bionic sludge-removing scraper is attached to the inner wall of the matching inner tank along the installation position of the guide rail.

[0010] Preferably, the metering and dosing module includes a flow guiding mixing cylinder welded to the lower end of the mud-enzyme mixture output main pipe, and a metering valve and a jet nozzle are sequentially connected to the front end of the flow guiding mixing cylinder along the material flow direction.

[0011] Preferably, a rotating rod is provided in the center of the rear end of the flow mixing cylinder, and a bidirectional material blocking and bonding roller is fixedly sleeved on the front end surface of the rotating rod.

[0012] Preferably, the enzyme preparation storage and control box has an arc-shaped material guide groove inside, and a spiral propulsion roller is set in the center of the arc-shaped material guide groove. The front end of the spiral propulsion roller extends through the arc-shaped material guide groove to the upper end of the inner tank.

[0013] Preferably, the rear end of the spiral propulsion roller extends out to one side of the outer end of the enzyme preparation storage and control box and is equipped with a variable frequency motor.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention utilizes an intelligent process control terminal, a variable frequency motor, and a spiral propulsion roller to form a closed-loop dosing system. The motor speed is dynamically adjusted according to the sludge treatment volume and reaction progress, ensuring precise matching between enzyme dosage and treatment requirements. The special structure of the arc-shaped guide trough completely solves the problem of enzyme residue accumulation, ensuring zero waste during dosing. The precise and efficient utilization of biological enzymes not only replaces the consumption of traditional carbon sources, reducing reagent costs by more than 30%, but also avoids the secondary pollution risks such as COD fluctuations caused by traditional carbon source dosing, resulting in a dual improvement in environmental and economic benefits.

[0016] This invention utilizes a high-speed shear motor-driven, circular stirring frame (composed of an upper support block, a lower support block, and four mounting plates) to form a full-section stirring trajectory with a telescopic adjustable guide column as the axis. This completely eliminates dead zones in the stirring process, increasing the uniformity of mixing sludge and enzyme preparations by more than 40% and significantly improving catalytic degradation efficiency. Simultaneously, a flexible biomimetic sludge-removing scraper operates synchronously with the stirring frame, closely adhering to the inner wall of the tank to scrape away accumulated sludge. The flexible design avoids tank wall wear and eliminates the need for shutdown for sludge removal, enabling the reaction and sludge removal to proceed simultaneously. This design extends the continuous operating cycle of the device to twice that of traditional equipment, greatly reducing the maintenance cost of the inner tank.

[0017] The present invention features a bidirectional material-blocking and bonding roller driven by an adjustable speed motor. This roller is tightly bonded to the main outlet orifice of the mud-enzyme mixture via a rubber arc plate. The feeding rate is stably controlled by the rotation rhythm, forming a primary pressure stabilization. The metering valve collects flow data in real time and feeds it back to the intelligent process control terminal. The terminal fine-tunes the motor speed to achieve a secondary precise flow control. The material is then ejected at high speed through a jet nozzle. Compared with the flow fluctuation range of existing technologies, the output stability of this device is greatly improved. It can directly adapt to the feeding needs of biochemical tanks of different sizes without the need for additional buffer and adjustment equipment. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-5 As shown, the present invention provides a technical solution: a bio-enzyme-based sludge reduction device that replaces traditional carbon sources, comprising a composite enzyme catalytic reaction vessel 1, an enzyme preparation storage and control box 2, a metering and dosing module 3, and a composite stirring reaction unit 4, which realizes sludge reduction in situ while replacing traditional carbon sources with bio-enzymes, thereby improving environmental protection and efficiency.

[0026] The composite enzyme catalytic reactor 1 serves as the core reaction carrier. Its lower surface is equipped with stable supports 11, its outer surface with a liquid level tank 12, and its interior center with an inner tank 17. The bottom is connected to a protective box 16 and a main outlet pipe 18 for the mud-enzyme mixture. The upper end is equipped with an adaptive air pump 15, a process water injection pipe 14, and an enzyme preparation storage and control tank 2. The enzyme preparation storage and control tank 2 has an intelligent process control terminal 13 on its surface and an arc-shaped material guide trough 22 and a spiral propulsion roller 23 inside. The spiral propulsion roller 23 is driven by a variable frequency motor 24, extending from its front end through the material guide trough to the inner tank 17, supplying biological enzymes through an enzyme injection pipe 21.

[0027] The composite stirring reaction unit 4 is located in the center of the inner tank 17, and includes an upper support block 41, a lower support block 42 and four mounting plates 45 vertically distributed. The upper support block 41 has a high-strength bearing 411 fitted with a telescopic adjustment guide post 43 connected to the adaptive air pump 15, and a support rod 44 is embedded in the limiting groove around it. The lower support block 42 has a linkage rod 47 installed around it, and a connecting rod that leads to the driven gear plate 48. The driven gear plate 48 meshes with the lead screw 49 in the protective box 16. The lead screw 49 is driven by a high-speed shearing motor 410. The mounting plate 45 connects the support rod 44 and the linkage rod 47. Its guide rail is equipped with a flexible bionic sludge scraper 46 that can be attached to the inner wall of the inner tank 17.

[0028] The metering and dosing module 3 is located at the lower end of the output main pipe 18, including a flow guiding mixing cylinder 31. The front end is connected to the metering valve 33 and the jet nozzle 32 along the material flow direction. The rear end rotating rod 34 is equipped with a bidirectional material blocking and bonding roller 35, whose rubber arc plate is sealed with the flow hole of the output main pipe 18. The rotating rod 34 is driven by an adjustable speed drive motor 36 to achieve accurate metering output.

[0029] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the composite stirring reaction unit 4, the upper support block 41 and the lower support block 42 are vertically aligned. The former is supported by a support rod 44 embedded in a limiting groove, and the latter is supported by a linkage rod 47 embedded in an installation groove. The upper and lower ends of the four mounting plates 45 are movably connected to the support rod 44 and the linkage rod 47, respectively, forming a ring-shaped adjustable stirring frame. The flexible bionic sludge scraper 46 is fixed to the guide rail on the front surface of the mounting plate 45 by bolts. The position can be pre-adjusted to achieve a tight fit with the inner wall of the inner tank 17, laying the foundation for the sludge sludge movement. The telescopic adjustment guide column 43, which is sleeved on the central endurance bearing 411 of the upper support block 41, is connected to the adaptive air pump 15 at its upper end, which can drive the frame to move up and down. The lower support block 42 is connected to the driven gear plate 48 in the protective box 16 through a connecting rod, which meshes with the lead screw 49 driven by the high-speed shear motor 410, providing power for the rotation of the frame.

[0030] After the high-speed shear motor 410 starts, it drives the lower bearing block 42 to rotate via the meshing transmission of the lead screw 49 and the driven gear plate 48. Through the linkage rod 47, it drives the four mounting plates 45 to make circular motion around the telescopic adjustment guide column 43 as the axis. The support rod 44 rotates synchronously along the limiting groove of the upper bearing block 41, forming a three-dimensional rotating stirring trajectory covering the cross section of the inner tank 17. The speed can be precisely controlled to adapt to the mixing requirements of sludge and enzyme preparations with different viscosities. At the same time, the adaptive air pump 15 drives the telescopic adjustment guide column 43 to move up and down along the endurance bearing 411 based on the data fed back from the liquid level tank 12 of the inner tank 17, so as to achieve no dead angle coverage of the stirring range. The flexible bionic sludge scraper 46 fixed to the mounting plate 45 will rotate synchronously with the mounting plate 45 and scrape the accumulated sludge against the inner wall. With the lifting action of the frame, it forms an all-round sludge cleaning of "rotation scraping + up and down sweeping", avoiding the impact of sediment on reaction efficiency.

[0031] according to Figure 1 and Figure 5 As shown, the enzyme preparation storage and control box 2 includes an intelligent process control terminal 13 and an enzyme injection tube 21: the surface-mounted intelligent process control terminal 13 serves as the core control unit, which can realize real-time control of enzyme preparation dosage and delivery rate, as well as monitoring of operating status; the enzyme injection tube 21 connected at the upper end extends into the storage and control box, providing a channel for replenishing enzyme preparation and ensuring continuous supply.

[0032] The enzyme preparation storage and control box 2 has an arc-shaped guide trough 22 inside. The arc-shaped structure of the guide trough can reduce the residual accumulation of enzyme preparation during the transportation process. A spiral propulsion roller 23 is set in the center of the arc-shaped guide trough 22. Its front end passes through the arc-shaped guide trough 22 and extends to the upper end of the inner tank 17 of the composite enzyme catalytic reaction vessel 1, directly and accurately transporting the enzyme preparation to the reaction area, avoiding the addition delay caused by the excessively long transportation path.

[0033] The rear end of the spiral propulsion roller 23 extends out to one side of the outer end of the enzyme preparation storage and control box 2, and a variable frequency motor 24 is installed therecorrespondingly. During operation, the intelligent process control terminal 13 sends a control signal to the variable frequency motor 24 according to the reaction requirements, and drives the spiral propulsion roller 23 to rotate at a corresponding speed by adjusting the motor speed. The spiral blades push the enzyme preparation in the arc-shaped guide trough 22 to be conveyed forward at a uniform speed, and finally accurately added to the inner tank 17.

[0034] according to Figure 1 and Figure 5 As shown, the metering and dosing module 3 is installed at the lower end of the mud-enzyme mixture output main pipe 18 of the composite enzyme catalytic reactor 1. The flow guide mixing cylinder 31 is used as the basic carrier, and its rear end is welded and fixed to the lower end of the mud-enzyme mixture output main pipe 18 to ensure the sealing and stability of the material conveying. Along the material flow direction, the front end of the flow guide mixing cylinder 31 is connected to the metering valve 33 and the jet nozzle 32 in sequence.

[0035] A rotating rod 34 is installed in the center of the rear end of the flow mixing cylinder 31. A bidirectional material blocking and bonding roller 35 is fixedly sleeved on the front end surface of the rotating rod 34. Rubber arc plates are arranged on both sides of the bonding roller. The rubber arc plates are tightly fitted and sealed with the lower end flow hole of the mud-enzyme mixture output main pipe 18, which can effectively block uncontrolled leakage of materials. The rear end of the rotating rod 34 extends out of the rear end of the flow mixing cylinder 31 and is fixedly connected to an adjustable speed drive motor 36, which provides power for the coordinated control of material blocking and feeding.

[0036] The adjustable speed drive 36 drives the rotating rod 34 to rotate according to the material conveying requirements, which drives the bidirectional material-blocking and bonding roller 35 to operate synchronously. Through the bonding and rotation of the rubber arc plate and the output main pipe flow hole, the material is conveyed in a stable pressure and quantity. The mud-enzyme mixture after pressure stabilization enters the flow guiding and mixing cylinder 31 for buffering and guiding, and then flows through the metering valve 33. The metering valve monitors and precisely controls the material flow rate in real time to ensure that the dosage meets the process requirements. Finally, the precisely metered material is sprayed out at high speed through the jet nozzle 32 to enhance the mixing effect of the material with the subsequent reaction system.

[0037] The overall effect achieved by the organization is as follows:

[0038] Before the device is started, the core parameters are preset through the intelligent process control terminal 13 on the surface of the enzyme preparation storage and control box 2. The operator adds sufficient biological enzyme preparation to the enzyme preparation storage and control box 2 through the enzyme injection tube 21 and injects an appropriate amount of reaction medium into the inner tank 17 through the process water injection pipe 14. The intelligent process control terminal 13 monitors the liquid level data of the liquid level tank 12 of the inner tank 17 in real time to ensure that the initial reaction environment meets the process requirements. At the same time, the power components such as the adjustable speed drive motor 36, the high-speed shear motor 410, and the frequency conversion motor 24 complete the standby self-test. The flexible bionic dredging scraper 46 is pre-adjusted to a state that can fit tightly against the inner wall of the inner tank 17 through the guide rail bolts. The rubber arc plate of the bidirectional material blocking and bonding roller 35 forms an initial seal with the flow hole of the mud enzyme mixture output main pipe 18.

[0039] The intelligent process control terminal 13 sends a speed control signal to the variable frequency motor 24 according to the preset sludge treatment volume and enzyme dosage ratio. After the variable frequency motor 24 starts, it drives the spiral propulsion roller 23 to rotate in the arc-shaped guide trough 22. The arc-shaped structure of the arc-shaped guide trough 22 can avoid the accumulation of enzyme preparation residue. The spiral blade generates directional thrust by rotating, which stably transports the enzyme preparation along the guide trough to the front end and accurately injects it into the inner tank 17 of the composite enzyme catalytic reaction vessel 1. The speed of the spiral propulsion roller 23 is linearly related to the enzyme dosage. The intelligent process control terminal 13 can dynamically adjust the speed of the variable frequency motor 24 according to the reaction process in the inner tank 17 to ensure that the enzyme concentration is always maintained in the optimal catalytic range.

[0040] The intelligent process control terminal 13 starts the high-speed shearing motor 410. The output shaft of the high-speed shearing motor 410 drives the lead screw 49 in the protective box 16 to rotate. The lead screw 49 meshes with the driven gear 48 on the connecting rod of the lower bearing block 42, converting the rotational motion into the circular motion of the driven gear 48, which drives the lower bearing block 42 to rotate synchronously. The lower bearing block 42 drives the four mounting plates 45 to make circular motion around the telescopic adjustment guide post 43 through the linkage rod 47 in the mounting groove. The upper bearing block 41 forms an upper limit on the mounting plate 45 through the support rod 44 in the limiting groove. The four mounting plates 45 form a surrounding stirring frame, achieving comprehensive stirring without dead angles. The inner tank 17 of the composite enzyme catalytic reactor 1 provides a stable and sealed environment for the reaction. The liquid level tank 12 monitors the volume change of the reaction system in real time to ensure that the reaction pressure and liquid level are maintained within a reasonable range. The flexible biomimetic sludge scraper 46 on the guide rail on the front surface of the mounting plate 45 moves synchronously with the mounting plate 45. The scraper is in close contact with the inner wall of the inner tank 17 to scrape off the sludge deposits attached to the inner wall of the inner tank 17 in real time. The scraper adopts a flexible biomimetic design to avoid wear on the tank wall and ensure long-term stable sludge removal effect.

[0041] After being catalytically degraded in the inner tank 17, the mud-enzyme mixture enters the metering and dosing module 3 through the mud-enzyme mixture output manifold 18. The intelligent process control terminal 13 sends instructions to the adjustable speed drive motor 36 according to the output requirements. The drive motor drives the rotating rod 34 and the bidirectional material-blocking bonding roller 35 to rotate. The rubber arc plates on both sides of the bonding roller are in close contact with the flow holes of the mud-enzyme mixture output manifold 18. The material falling rate is controlled by the rotation to achieve stable pressure and quantitative conveying. After entering the guide mixing cylinder 31 for buffering and guiding, the mud-enzyme mixture flows through the metering valve 33. The metering valve 33 collects the flow data in real time and feeds it back to the intelligent process control terminal 13. The terminal achieves precise flow control by finely adjusting the speed of the adjustable speed drive motor 36. Finally, the precisely metered mud-enzyme mixture is sprayed out at high speed through the jet nozzle 32.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
