Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a wastewater recycling treatment device based on intelligent sensing and dynamic adjustment. Background Technology

[0002] With increasingly stringent environmental protection requirements, wastewater recycling technology is being applied more and more widely in industrial, agricultural, and residential sectors.

[0003] Traditional wastewater treatment equipment typically includes multiple independent units such as sedimentation, biological reaction, and filtration. Each unit relies on an independent power source and control unit. For example, flocculant dosing requires an independent dosing pump and control system, while biological aeration requires an independent blower or aeration pump.

[0004] This modular, independently operating mode leads to the following significant drawbacks in the entire device:

[0005] (1) The equipment has high energy consumption and complex structure. Multiple power sources not only increase the manufacturing cost of the equipment itself, but also lead to a sharp increase in operating energy consumption.

[0006] (2) The level of automation and intelligence is low. The various process parameters of the existing equipment (such as dosage and aeration) often need to be set and adjusted manually based on experience. It is difficult to achieve dynamic and coordinated precise adjustment based on the real-time changes in the influent water quality and quantity. Problems such as excessive or insufficient dosage and mismatch between aeration and stirring often occur, affecting the treatment effect.

[0007] Therefore, there is an urgent need for an integrated wastewater recycling treatment equipment that can integrate multiple processing units, reduce energy consumption, and perform intelligent linkage adjustment based on real-time operating conditions. Summary of the Invention

[0008] This application aims to at least partially solve one of the technical problems in the aforementioned technologies.

[0016] As a further description of the above technical solution: a baffle is provided in the middle of the filter box, the baffle is provided with filter holes, a multi-layer filter screen is provided above the baffle, and the bottom of the baffle is connected to an external disinfectant feeding pipe.

[0017] As a further description of the above technical solution: the upper part of the sedimentation tank is connected to the bottom of the bioreactor via a sedimentation outlet pipe, the upper part of the bioreactor is connected to the upper part of the filter tank via a filter inlet pipe, and the lower part of the filter tank is connected to a filter outlet pipe.

[0018] As a further description of the above technical solution: the wastewater recycling treatment equipment based on intelligent sensing and dynamic adjustment of this application also includes an adjustment structure.

[0020] According to the wastewater recycling equipment based on intelligent sensing and dynamic adjustment disclosed in this application, the single rotational power of the stirring structure can be converted into two synchronous actions—driving flocculant feeding and aeration—through the linkage structure. Only one drive motor is needed to simultaneously complete biological stirring, chemical dosing, and gas supply, greatly simplifying the mechanical structure, reducing the number of independent power sources, and lowering the equipment's manufacturing cost and operating energy consumption. Through the cooperation of a flow sensor and controller installed at the inlet, the treatment intensity and influent load are linked. When the influent flow rate increases, the controller increases the stirring speed, which not only strengthens the biological stirring intensity but also synchronously accelerates the flocculant dosing frequency and aeration frequency through the linkage structure, thus achieving precise control over the dosage and aeration rate. Automatic matching of multiple parameters, such as the volume of water to be treated, ensures stable and efficient treatment results. Inside the sedimentation tank, a conductivity probe monitors the sludge level in real time, automatically opening an electronic valve to discharge sludge when the level reaches a set value. This achieves precise and automated sludge discharge, replacing the imprecise traditional methods that rely on experience or timed control. This ensures the sedimentation tank is always in optimal working condition, preventing sludge accumulation or ineffective discharge, and further enhancing the overall system's intelligence. Furthermore, the added adjustment structure allows for easy adjustment of the reciprocating rod's stroke, flexibly adjusting the dosage of flocculant and the aeration rate per cycle. This enables fine-tuning according to different water quality treatment needs, enhancing the equipment's applicability and the reliability of its treatment effects.

[0038] The embodiments of this application are described in detail below. Examples of these embodiments are shown 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 this application, and should not be construed as limiting this application.

[0039] The following description, in conjunction with the accompanying drawings, describes a wastewater recycling treatment device based on intelligent sensing and dynamic adjustment, according to an embodiment of this application.

[0040] like Figures 1 to 3 As shown in the figure, the wastewater recycling treatment equipment based on intelligent sensing and dynamic adjustment in this application embodiment may include a sedimentation tank 100, a flocculation feeding structure 200, a biological reaction tank 300, a filter tank 400, an aeration structure 500, and a linkage structure 600.

[0041] The flocculation feeding structure 200, which can be flexibly extruded and fed, is connected to the top of the sedimentation tank 100. The sedimentation tank 100, the bioreactor 300, and the filter tank 400 are connected in sequence. The air outlet of the aeration structure 500, which can be pushed to release air, is connected to the bottom of the bioreactor 300.

[0042] The bioreactor 300 is equipped with a stirring structure 310. The drive end of the linkage structure 600 is connected to the output end of the stirring structure 310. The linkage structure 600 includes a reciprocating rod 650 that can move linearly back and forth. One end of the reciprocating rod 650 intermittently squeezes the flocculation feeding structure 200 so that the flocculant is periodically added into the sedimentation tank 100. The other end of the reciprocating rod 650 is slidably sealed in the aeration chamber 510 of the aeration structure 500 so as to periodically push the gas from the aeration chamber 510 into the bioreactor 300.

[0043] A flow sensor 1011 is installed at the liquid inlet of the sedimentation tank 100. The flow sensor 1011 is connected to the stirring structure 310 through a controller.

[0044] To clearly illustrate the previous embodiment, in one embodiment of this application, as follows: Figure 3 and Figure 4 As shown, the linkage structure 600 also includes a rotating disk 610, an eccentric rod 620, a rotating arm 630, and a shift fork head 640.

[0045] The rotating disk 610 is located on the output end of the stirring structure 310. The eccentric rod 620 is rotatably and eccentrically mounted on the rotating disk 610. One end of the rotatable rotating arm 630 is pivotally connected to the eccentric rod 620, and the other end is connected to the shift fork head 640. The reciprocating rod 650 is provided with a protrusion 651, which is embedded in the shift fork head 640. The bottom of the reciprocating rod 650 is provided with a support seat 654 for limiting support.

[0046] As one possible scenario, such as Figure 5 As shown, the flocculation feeding structure 200 includes a flocculation chamber 210, a drug delivery tube 220, a first one-way valve 230, an extension chamber 240, and a second one-way valve 250.

[0047] The flocculation chamber 210 is connected to the top of the sedimentation tank 100, and the administration tube 220 is connected to the side wall of the flocculation chamber 210. The first one-way valve 230 is installed in the administration tube 220, which only allows the flocculant to be transferred from the administration tube 220 to the flocculation chamber 210. The second one-way valve 250 is installed at the top of the flocculation chamber 210, which only allows air to be transferred from the outside to the flocculation chamber 210.

[0048] The extension chamber 240 is connected to the flocculation chamber 210, and a deformable elastic diaphragm 211 is provided at the connection. One end of the reciprocating rod 650 is slidably disposed in the extension chamber 240, and the end is provided with a compression head 652 for compressing the elastic diaphragm 211. A discharge check valve 260 is provided at the connection between the flocculation chamber 210 and the top of the sedimentation tank 100, which only allows the flocculant to be transferred from the flocculation chamber 210 to the sedimentation tank 100.

[0049] In addition, such as Figure 6As shown, the aeration structure 500 includes an aeration chamber 510, an air supply pipe 520, a third one-way valve 530, and a fourth one-way valve 540.

[0050] The reciprocating rod 650 has a piston head 653 at its end. The piston head 653 is slidably sealed in the aeration chamber 510. The end of the aeration chamber 510 away from the reciprocating rod 650 is connected to the air supply pipe 520. The third one-way valve 530 is located in the air supply pipe 520, allowing gas to be transmitted from the aeration chamber 510 to the air supply pipe 520. The fourth one-way valve 540 is located on the aeration chamber 510 near the air supply pipe 520, allowing gas to enter the aeration chamber 510 from the outside.

[0051] Specifically, after the equipment is started, the stirring structure 310 inside the bioreactor 300 begins to operate. Its rotation speed is dynamically controlled by the flow sensor 1011 at the liquid inlet of the sedimentation tank 100 through the controller. The output end of the stirring structure 310 drives the rotating disk 610 of the linkage structure 600 to rotate synchronously. The eccentric rod 620 moves with the rotating disk 610, which in turn pushes the rotating arm 630, which is pivotally connected to it, to swing back and forth around its own pivot axis. The fork head 640 at the other end of the rotating arm 630 pushes the protrusion 651 of the reciprocating rod 650, so that the reciprocating rod 650 moves back and forth in a straight line. The support seat 654 provides a limiting support for the reciprocating rod 650 to prevent deviation during the reciprocating process and ensure the stability of the movement direction.

[0052] Wastewater flows into the sedimentation tank 100 through the inlet. During the inflow process, the flow sensor 1011 collects wastewater flow data in real time and transmits the data to the controller. The controller adjusts the rotation speed of the stirring structure 310 according to the flow signal. If the wastewater flow increases,

[0053] The controller increases the stirring speed, and the power transmission frequency of the linkage structure 600 increases synchronously, and the reciprocating frequency of the reciprocating rod 650 increases accordingly, ensuring that the flocculant dosage matches the wastewater volume; if the flow rate decreases, the stirring speed and reciprocating frequency decrease synchronously to avoid flocculant waste.

[0054] When the flocculant is fed, the reciprocating rod 650 slides into the extension cavity 240 with the reciprocating motion. The extrusion head 652 at its end gradually approaches and squeezes the elastic diaphragm 211. The elastic diaphragm 211 is deformed by the extrusion, which in turn compresses the internal space of the flocculant cavity 210, causing the pressure inside the flocculant cavity 210 to rise rapidly.

[0055] At this time, the first one-way valve 230 automatically closes because the pressure inside the flocculation chamber 210 is greater than the pressure on the dosing pipe 220 side, preventing the flocculant from flowing back into the dosing pipe 220. The second one-way valve 250 automatically closes because the pressure inside the flocculation chamber 210 is greater than the external atmospheric pressure. The discharge one-way valve 260 opens because the pressure inside the flocculation chamber 210 is greater than the pressure on the sedimentation tank 100 side, driven by the positive pressure difference, squeezing the flocculant in the flocculation chamber 210 into the sedimentation tank 100, where it is fully mixed with the sewage to form flocs, completing one flocculant addition.

[0056] When the reciprocating rod 650 drives the extrusion head 652 to retract to the outside of the extension chamber 240, the elastic diaphragm 211 returns to its original shape due to its own elasticity, and the internal space of the flocculation chamber 210 gradually expands, forming a negative pressure environment. At this time, the discharge check valve 260 automatically closes, the first check valve 230 automatically opens due to the negative pressure in the flocculation chamber 210, and the second check valve 250 opens at the same time due to the negative pressure in the flocculation chamber 210. Outside air enters the flocculation chamber 210, quickly balancing the negative pressure in the chamber and preparing for the next round of extrusion.

[0057] After the wastewater in the sedimentation tank 100 is mixed with the flocculant, the flocs gradually settle, and the clarified wastewater in the upper layer flows into the biological reactor 300.

[0058] The stirring structure 310 inside the bioreactor 300 rotates continuously, which fully stirs the sewage, so that the sewage comes into uniform contact with the degrading microorganisms inside the bioreactor 300, thereby accelerating the biodegradation reaction of organic matter in the sewage.

[0059] During aeration, the reciprocating rod 650 moves away from the aeration chamber 510 with the reciprocating motion, and the piston head 653 at its end slides outward from the aeration chamber 510 at the same time, so that a negative pressure is formed inside the aeration chamber 510. The third one-way valve 530 closes and the fourth one-way valve 540 opens, and outside air enters the aeration chamber 510 along the air intake channel.

[0060] When the reciprocating rod 650 drives the piston head 653 to slide into the aeration chamber 510, the internal space of the aeration chamber 510 is compressed, the pressure inside the chamber increases, the fourth one-way valve 540 automatically closes, and the third one-way valve 530 opens. The air inside the chamber is transported to the bottom of the bioreactor 300 along the air supply pipe 520 and diffuses into the sewage in the form of tiny bubbles, providing sufficient oxygen for the degrading microorganisms and ensuring the efficient progress of the biodegradation reaction.

[0061] Wastewater that has undergone organic degradation in the bioreactor 300 flows into the filter tank 400, where it undergoes deep purification (such as intercepting residual microscopic suspended solids and microbial metabolic products) to finally obtain water that meets treatment standards. This water can be discharged or recycled according to actual needs, completing the entire wastewater recycling process.

[0062] It should be noted that the reciprocating motion of the reciprocating rod 650 synchronously drives the flocculant addition and aeration actions. Each time the flocculant is squeezed and added, an aeration push and oxygen supply is completed simultaneously; each time the flocculant is reset and replenished, an aeration intake and storage is completed simultaneously, thus avoiding asynchronous operation of each link.

[0063] In one embodiment of this application, such as Figure 7 As shown, a sedimentation tank 100 is connected to a sedimentation inlet pipe 101, a flow sensor 1011 is installed inside the sedimentation inlet pipe 101, a guide plate 102 is installed inside the sedimentation tank 100, an electronic valve 103 is installed at the drain port at the bottom of the sedimentation tank 100, and a conductivity probe 104 is installed on the side wall of the sedimentation tank 100 below the guide plate 102. The conductivity probe 104 is connected to the electronic valve 103 through a controller, so that after the flocculation layer in the sedimentation tank 100 rises to the level of the conductivity probe 104, the controller controls the electronic valve 103 to open for drainage.

[0064] It should be noted that the guide plate 102 is an inclined or baffle plate to stabilize the flow of sewage and ensure flocculation and sedimentation.

[0065] It is understandable that, since the conductivity of the flocculated layer at the bottom is different from that of the supernatant at the top, the conductivity of the flocculated layer at the bottom changes significantly when it accumulates to the position of the conductivity probe 104. Therefore, the controller can control the opening of the electronic valve 103 according to the changing conductivity signal and discharge the flocculated layer at the bottom by setting the discharge time.

[0066] In one embodiment of this application, such as Figure 8 As shown, the stirring structure 310 includes a first drive motor 311, a rotating shaft 312, and stirring blades 313.

[0067] The first drive motor 311 is located at the bottom of the bioreactor 300, and the rotating shaft 312 is connected to the output end of the first drive motor 311. Multiple sets of stirring blades 313 are arranged from top to bottom on the rotating shaft 312. The rotating shaft 312 extends outside the bioreactor 300, and the rotating disk 610 is coaxially connected to the rotating shaft 312.

[0068] It should be noted that when the stirring structure 310 is working, the first drive motor 311 drives the rotating shaft 312 to rotate, thereby causing the stirring blades 313 to rotate, so as to achieve uniform mixing of sewage and microorganisms in the biological reaction tank 300.

[0069] In one embodiment of this application, such as Figure 9As shown, a baffle 403 is provided in the middle of the filter box 400. Filter holes 4031 are provided on the baffle 403. A multi-layered filter screen plate 404 is provided above the baffle 403. The lower part of the baffle 403 is connected to an external disinfectant feeding pipe.

[0070] It should be noted that the wastewater enters the filter box 400 from the biological reactor 300 and enters the upper part of the filter box 400 through the filter inlet pipe 401. The wastewater first penetrates the multi-layer filter screen 404 from top to bottom. During this process, residual solid impurities in the wastewater are intercepted layer by layer, achieving deep physical purification. The filtered water collects on the upper surface of the baffle 403 and flows into the area below the baffle 403 through the filter holes 4031. Disinfectant is continuously or quantitatively injected through the disinfectant feed pipe to fully mix the wastewater and disinfectant, killing residual bacteria, viruses and other pathogenic microorganisms in the water, completing the final disinfection treatment. Finally, the filtered and disinfected water that meets the standards is discharged from the system through the filter outlet pipe 402 located at the bottom of the box, and can be reused or safely discharged.

[0071] In one embodiment of this application, the upper part of the sedimentation tank 100 is connected to the bottom of the bioreactor 300 through a sedimentation outlet pipe 301, the upper part of the bioreactor 300 is connected to the upper part of the filter tank 400 through a filter inlet pipe 401, and the lower part of the filter tank 400 is connected to a filter outlet pipe 402.

[0072] like Figures 10 to 13 As shown, the wastewater recycling treatment equipment based on intelligent sensing and dynamic adjustment in this application embodiment also includes an adjustment structure 700. The sedimentation tank 100, the biological reaction tank 300 and the filter tank 400 are connected by a support frame 105. The adjustment structure 700 is set on the support frame 105, and the pivot shaft of the rotating arm 630 is set on the moving end of the adjustment structure 700.

[0073] To clearly illustrate the previous embodiment, in one embodiment of this application, the adjustment structure 700 includes a bidirectional lead screw 710, a lead screw slider 720, a second drive motor 730, a sliding rod 740, and a sliding sleeve 750.

[0074] The bidirectional lead screw 710 and the sliding rod 740 are arranged in parallel. The lead screw slider 720 is set on the bidirectional lead screw 710. The sliding sleeve 750 is slidably set on the sliding rod 740. The lead screw slider 720 and the sliding sleeve 750 are connected by a connecting plate. The rotating arm 630 is pivotally set on the connecting plate. The output end of the second drive motor 730 is connected to the bidirectional lead screw 710.

[0075] Specifically, under normal conditions, the reciprocating rod 650 performs a fixed-stroke reciprocating motion, and the dosage and aeration rate are fixed. When it is necessary to adjust the treatment parameters (for example, when the concentration of pollutants in the influent increases and the dosage of chemicals needs to be increased), the controller starts the second drive motor 730, which drives the bidirectional lead screw 710 to rotate. The lead screw slider 720 moves axially along the bidirectional lead screw 710 and drives the sliding sleeve 750 to slide synchronously on the sliding rod 740 through the connecting plate, thereby changing the position of the pivot axis of the rotating arm 630 installed on it.

[0076] When the pivot axis moves closer to the rotating disk 610, the effective lever arm of the rotating arm 630 becomes shorter. Under the same rotation amplitude of the eccentric rod 620, the swing amplitude of the fork head 640 will increase, resulting in a larger stroke of the reciprocating rod 650, thereby increasing the amount of flocculant added per cycle and the amount of aeration per cycle.

[0077] When the pivot axis moves away from the rotating disk 610, the effective lever arm of the rotating arm 630 becomes longer, the swing amplitude of the fork head 640 decreases, resulting in a smaller stroke of the reciprocating rod 650, thereby reducing the amount of flocculant added and the amount of aeration per cycle.

[0078] In summary, the wastewater recycling treatment equipment based on intelligent sensing and dynamic adjustment according to the embodiments of this application, through the setting of the linkage structure 600, can convert the single rotational power of the stirring structure 310 into two synchronous actions of driving flocculant feeding and aeration. Only one drive motor is needed to simultaneously complete biological stirring, chemical dosing, and gas supply, which greatly simplifies the mechanical structure, reduces the number of independent power sources, and lowers the manufacturing cost and operating energy consumption of the equipment. Through the cooperation of the flow sensor 1011 and the controller, the treatment intensity and influent load are linked. When the influent flow increases, the controller increases the stirring speed, which not only strengthens the biological stirring intensity, but also synchronously accelerates the frequency of flocculant dosing and aeration through the linkage structure 600, realizing the control of chemical dosage and aeration volume. Automatic matching of multiple parameters, such as the volume of water to be treated, ensures stable and efficient treatment results. Inside the sedimentation tank 100, a conductivity probe 104 monitors the sludge level in real time, automatically opening the electronic valve 103 to discharge sludge when the level reaches a set value. This achieves precise and automated sludge discharge, replacing the imprecise traditional methods that rely on experience or timed control. This ensures the sedimentation tank is always in optimal working condition, preventing sludge accumulation or ineffective discharge, and further enhancing the overall system's intelligence. Furthermore, the added adjustment structure 700 allows for convenient adjustment of the reciprocating rod 650's stroke, flexibly adjusting the dosage of flocculant and the aeration rate per cycle. This enables fine-tuning according to different water quality treatment needs, enhancing the equipment's applicability and the reliability of its treatment effect.
