Description

Technical Field

[0001] This invention relates to the field of water purification technology, and in particular to an IoT-based method and device for early warning of MBBR operation status. Background Technology

[0002] MBBR, short for Moving Bed Biofilm Reactor, is another innovative type of biofilm reactor that has received considerable attention from researchers in recent years. It was developed to solve the complex operations required by fixed bed reactors (which require periodic backwashing), fluidized beds (which require fluidizing the carrier), and submerged biofilters (which require cleaning the filter media and replacing the aerators when clogging occurs).

[0003] Patent application CN120309083A discloses an MBBR (Medium-Range Biofilm Batch) suspended packing biofilm thickness monitoring and control system. This system achieves dynamic monitoring of the suspended packing biofilm thickness through the coordinated operation of a monitoring module, an early warning module, and a control module. It immediately issues an early warning upon detecting abnormal growth or shedding and takes timely measures to control the biofilm thickness, thus comprehensively improving water treatment capacity. However, this system controls biofilm thickness by adjusting aeration intensity, which is prone to misjudgment of the overall thickness due to individual special circumstances and cannot promptly correct individual malfunctions in the packing material.

[0004] Therefore, it is necessary to propose an IoT-based MBBR operation status early warning method and device to solve the above problems. This would address the issues that traditional MBBR systems control biofilm thickness by adjusting aeration intensity, which can easily lead to misjudgments of the overall situation due to individual special circumstances and the inability to promptly correct individual malfunctioning packing materials. Summary of the Invention

[0005] This invention provides an Internet of Things-based MBBR operation status early warning method and device, which solves the problem that traditional vehicle-mounted refrigerators are prone to relative displacement between the front and the lower rear of the central control unit, and lack installation stability.

[0006] The technical problem solved by this invention is achieved by the following technical solution:

[0007] An IoT-based method for early warning of MBBR operational status includes the following steps:

[0008] a. The sampling device is used to sample the packing material in the MBBR tank to obtain packing material samples;

[0009] b. The image analysis device acquires the biofilm thickness of the filler sample and compares it with the preset standard filler. When the thickness difference exceeds the preset range, it is judged as unqualified.

[0010] c. When the analysis finds that a filler sample is unqualified, the data transmission device will send the analysis results to the remote terminal through the server;

[0011] d. The remote terminal receives the user's command to change the packing and transmits it back to the data transmission device;

[0012] e. The data transmission device sends control commands to the supplementary device;

[0013] f. The replenishment device uses an image analysis device to screen and extract new filler material that is closest to the preset standard filler material in the culture tank;

[0014] g. The replenishment device releases new packing material into the MBBR tank to replace the packing sample.

[0015] Furthermore, when several filler samples are extracted, the image analysis device obtains the number of qualified and unqualified samples.

[0016] Furthermore, the sampling device places the unqualified filler samples into the unqualified box.

[0017] Furthermore, the remote terminal allows users to select the number of packing materials to be replaced and the thickness of the biofilm.

[0018] Furthermore, the image analysis device also acquires the degree of damage to the packing sample, and judges it as unqualified when the size difference between the packing sample and the preset standard packing exceeds the preset value.

[0019] Furthermore, the dimensional difference includes the length difference in the packing length direction and the difference in the grid area corresponding to the cross section of the packing perpendicular to the length direction.

[0020] An IoT-based MBBR operation status early warning device implements the aforementioned IoT-based MBBR operation status early warning method.

[0021] The device includes:

[0022] The sampling device is used to sample the packing material in the MBBR tank to obtain packing material samples;

[0023] MBBR water tanks are used for water purification.

[0024] Packing material, used to purify water in MBBR tanks;

[0025] The image analysis device is used to acquire the biofilm thickness of the filler sample and compare it with the preset standard filler. When the thickness difference exceeds the preset range, it is judged as unqualified.

[0026] The data transmission device is used to send the analysis results to a remote terminal via a server when the analysis finds that a filler sample is unqualified; the data transmission device also sends control commands to the supplementary device.

[0027] A server is used to transmit information between a data transmission device and a remote terminal.

[0028] The remote terminal is used to receive analysis results sent by the server; to receive user commands to change the packing material and to send them back to the data transmission device.

[0029] The supplementary device is used to receive control commands sent by the data transmission device; and to screen and extract new fillers that are closest to the preset standard fillers in the culture tank using an image analysis device.

[0030] Culture tanks are used to supply new packing material to the replenishment unit;

[0031] The non-conforming box is used to receive non-conforming filler samples captured by the sampling device;

[0032] The sampling device, image analysis device, data transmission device, and supplementary device are electrically connected to each other.

[0033] Furthermore, the sampling device includes a channel, a pumping device, a sampling conveyor belt, a sorting device, and a sorting conveyor belt. The channel extends horizontally, with one end of the channel having a downward-facing entrance. The sampling conveyor belt is located at the bottom of the channel and moves away from the channel entrance. The pumping device is located at the top of the channel and above the starting point of the sampling conveyor belt. The pumping device is used to draw the packing material from the MBBR water tank onto the sampling conveyor belt.

[0034] The sorting conveyor belts are provided in two directions and in opposite directions. One sorting conveyor belt conveys to the MBBR water tank and the other sorting conveyor belt conveys to the defective boxes. The end point of the sampling conveyor belt is adjacent to the starting point of the sorting conveyor belt. A sorting device for switching directions is provided between the two sorting conveyor belts. The sorting device is equipped with a switching baffle.

[0035] The image analysis device faces the sampling conveyor belt. When the filler is determined to be unqualified, the sorting device controls the switching baffle to allow the filler to enter the sorting conveyor belt leading to the unqualified box; when the filler is determined to be qualified, the sorting device controls the switching baffle to allow the filler to enter the sorting conveyor belt leading to the MBBR water tank.

[0036] The image analysis device, data transmission device, water pumping device, sampling conveyor belt, sorting device, and sorting conveyor belt are electrically connected to each other.

[0037] Furthermore, the supplementary device includes an electric clamp, a moving device, and a telescopic plate. The electric clamp is driven by the moving device, which is located inside the culture tank. The culture tank has an outlet leading to the MBBR water tank. The telescopic plate is located at the outlet for opening and closing the outlet. The image analysis device is located at the bottom of the electric clamp and faces the bottom surface of the culture tank, or the image analysis device is located at the bottom surface of the electric clamp in the culture tank and faces the top of the culture tank.

[0038] The data transmission device, electric clamp, moving device, and telescopic plate are electrically connected to each other.

[0039] The beneficial effects of this invention are:

[0040] This invention employs the following steps: a sampling device samples the packing material within the MBBR tank to obtain packing material samples; an image analysis device acquires the biofilm thickness of the packing material samples and compares it with a preset standard packing material; when the thickness difference exceeds a preset range, it is judged as unqualified; when the analysis reveals that a packing material sample is unqualified, a data transmission device sends the analysis conclusion to a remote terminal via a server; the remote terminal receives the user's command to replace the packing material and sends it back to the data transmission device; the data transmission device sends a control command to a replenishment device; the replenishment device releases new packing material to the MBBR tank to replace the packing material samples, and the culture tank promptly provides qualified packing material to the MBBR tank, accurately selecting new packing material to replace individual problematic packing material in a timely manner. This achieves an IoT-based early warning system for MBBR operation status, solving the problem that traditional MBBR systems control biofilm thickness by adjusting aeration intensity, which can easily lead to misjudgments of the overall situation due to individual special circumstances and cannot promptly correct individual problematic packing material.

Detailed Implementation

[0051] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0052] See Figure 1 An IoT-based method for early warning of MBBR operational status includes the following steps:

[0053] An IoT-based method for early warning of MBBR operational status includes the following steps:

[0054] a. The sampling device is used to sample the packing material in the MBBR tank to obtain packing material samples;

[0055] b. The image analysis device acquires the biofilm thickness of the filler sample and compares it with the preset standard filler. When the thickness difference exceeds the preset range, it is judged as unqualified.

[0056] c. When the analysis finds that a filler sample is unqualified, the data transmission device will send the analysis results to the remote terminal through the server;

[0057] d. The remote terminal receives the user's command to change the packing and transmits it back to the data transmission device;

[0058] e. The data transmission device sends control commands to the supplementary device;

[0059] f. The replenishment device uses an image analysis device to screen and extract new filler material that is closest to the preset standard filler material in the culture tank;

[0060] g. The replenishment device releases new packing material into the MBBR tank to replace the packing sample.

[0061] This method involves sampling and comparing the biofilm thickness of the packing material samples with preset standard packing materials to identify substandard materials. These substandard materials are then remotely sent to the user, who can issue a replacement order. The culture tank promptly supplies the MBBR tank with qualified packing materials. Furthermore, image analysis devices screen and identify new packing materials that most closely match the preset standard, allowing for precise selection and timely replacement of individual problematic materials. This enables IoT-based early warning systems for MBBR operation. It addresses the problems of traditional MBBR systems that control biofilm thickness by adjusting aeration intensity, which can lead to misjudgments of the overall system due to individual special circumstances and an inability to promptly correct specific malfunctioning packing materials.

[0062] When multiple packing samples are extracted, the image analysis device obtains the number of qualified and unqualified samples. This provides the user with a clearer picture of the packing condition.

[0063] The sampling device places the unqualified packing material samples into the unqualified box 10. This allows for the timely collection of unqualified packing material for separate processing and prevents unqualified packing material from accidentally flowing into the MBBR water tank.

[0064] The remote terminal allows users to select the number of packing materials to replace. This allows users to replace the required number of packing materials as needed.

[0065] The remote terminal allows users to select the biofilm thickness for changing the packing material. This allows users to change the packing material to the desired biofilm thickness as needed.

[0066] The image analysis device also acquires information on the degree of damage to the packing sample. If the size difference between the packing sample and the preset standard packing exceeds a preset value, it is considered unqualified. This adds a damage level indicator to the biofilm thickness indicator, making the MBBR tank operate more stably.

[0067] The dimensional differences include the length difference along the length of the packing material and the difference in mesh area corresponding to the cross-section of the packing material perpendicular to its length. This allows for more accurate identification of the degree of damage.

[0068] See Figure 2 An IoT-based MBBR operation status early warning device is provided to implement the aforementioned IoT-based MBBR operation status early warning method.

[0069] The device includes:

[0070] Sampling device 1 is used to sample the packing material in the MBBR tank to obtain a packing material sample;

[0071] MBBR Pool 2 is used for water purification;

[0072] Packing material 3 is used to purify water in MBBR tank 2;

[0073] Image analysis device 4 is used to acquire the biofilm thickness of the filler sample and compare it with the preset standard filler. When the thickness difference exceeds the preset range, it is judged as unqualified.

[0074] Data transmission device 5 is used to send the analysis conclusions to remote terminal 7 via server 6 when the analysis finds that a filler sample is unqualified; data transmission device 5 sends control commands to supplementary device 8;

[0075] Server 6 is used to transmit information between data transmission device 5 and remote terminal 7;

[0076] Remote terminal 7 is used to receive analysis conclusions sent by server 6; receive user commands to change packing material and transmit them back to data transmission device 5;

[0077] Supplementing device 8 is used to receive control commands sent by data transmission device 5; and to screen and extract new fillers that are closest to the preset standard fillers in the culture tank using an image analysis device.

[0078] Culture tank 9 is used to provide new packing material for replenishment device 8;

[0079] The non-conforming box 10 is used to receive non-conforming filler samples grabbed by the sampling device 1;

[0080] The sampling device 1, image analysis device 4, data transmission device 5, and supplementary device 8 are electrically connected to each other.

[0081] In operation, packing material 3 is placed in the MBBR water tank 2 for water purification, and packing material is also placed in the cultivation tank 9 to cultivate and replace the old packing material 3. The image analysis device 4 periodically samples the packing material 3. When a packing material sample is deemed unqualified, the data transmission device 5 sends the analysis results to the remote terminal 7 via the server 6. The user can view the analysis status through the remote terminal 7 and issue control commands as needed. The replenishment device 8, based on the control commands sent by the data transmission device 5, uses the image analysis device to screen and extract new packing material in the cultivation tank that is closest to the preset standard packing material. This IoT-based MBBR operation status early warning device provides qualified packing material to the MBBR water tank in a timely manner through the cultivation tank, accurately screens new packing material, and thus promptly replaces individual problematic packing material. This achieves IoT-based MBBR operation status early warning, solving the problem of traditional MBBR systems controlling biofilm thickness by adjusting aeration intensity, which is prone to misjudgment of the overall situation due to individual special circumstances and cannot promptly correct individual malfunctioning packing material.

[0082] See Figures 3 to 5 The sampling device 1 includes a channel 11, a pumping device 12, a sampling conveyor belt 13, a sorting device 14, and a sorting conveyor belt 15. The channel 11 extends horizontally, with one end of the channel 11 having a downward-facing inlet. The sampling conveyor belt 13 is located at the bottom of the channel 11 and moves away from the inlet of the channel 11. The pumping device 12 is located at the top of the channel 11 and above the starting point of the sampling conveyor belt 13. The pumping device 12 is used to draw the packing material 3 from the MBBR pool 2 onto the sampling conveyor belt 13.

[0083] The sorting conveyor belt 15 is provided in two directions with opposite directions. One sorting conveyor belt 15 conveys to the MBBR pool 2, and the other sorting conveyor belt 15 conveys to the defective box 10. The end point of the sampling conveyor belt 13 is adjacent to the starting point of the sorting conveyor belt 15. A sorting device 14 for switching directions is provided between the two sorting conveyor belts 15. The sorting device 14 is provided with a switching baffle.

[0084] The image analysis device 4 is directed toward the sampling conveyor belt 13. When the filler 3 is determined to be unqualified, the sorting device 14 controls the switching baffle to allow the filler 3 to enter the sorting conveyor belt 15 leading to the unqualified box 10. When the filler 3 is determined to be qualified, the sorting device 14 controls the switching baffle to allow the filler 3 to enter the sorting conveyor belt 15 leading to the MBBR pool 2.

[0085] The image analysis device 4, data transmission device 5, water pumping device 12, sampling conveyor belt 13, sorting device 14, and sorting conveyor belt 15 are electrically connected to each other.

[0086] When sampling device 1 is running, pumping device 12 starts, randomly sucking the packing material 3 located in MBBR water tank 2 into channel 11. The pumped water is discharged back into MBBR water tank, and pumping device 12 stops operating at regular intervals, with the packing material 3 falling onto sampling conveyor belt 13. The inlet of channel 11 faces downwards to prevent the packing material 3 from accidentally entering channel 11 and affecting purification. Sampling conveyor belt 13 operates, conveying the packing material 3 to the image analysis device 4 for identification. Image analysis device 4 identifies and analyzes the packing material 3. When image analysis device 4 determines that packing material 3 is unqualified, sorting device 14 controls a switching baffle, causing packing material 3 to enter the sorting conveyor belt 15 leading to the unqualified box 10; when packing material 3 is determined to be qualified, sorting device 14 controls a switching baffle, causing packing material 3 to enter the sorting conveyor belt 15 leading to MBBR water tank 2. When the image analysis device 4 completes the preset number of samples, the sampling conveyor belt 13 stops conveying the packing material 3 to the sorting conveyor belt 15 and reverses to return the packing material 3 from the channel 11 back to the MBBR water tank 2. This allows the packing material 3 to enter the sampling device 1 only when sampling is needed, ensuring accurate sampling of the required quantity; it also allows qualified packing material 3 to be returned to the MBBR water tank 2, preventing waste during sampling; and it places unqualified packing material 3 into the unqualified box 10, promptly eliminating adverse factors to purification and contributing to the continuous and effective purification of the MBBR water tank 2.

[0087] See Figures 6 to 8 The supplementary device 8 includes an electric clamp 81, a moving device 82, and a telescopic plate 83. The electric clamp 81 is driven by the moving device 82, which is located inside the culture tank 9. The culture tank 9 has an outlet leading to the MBBR water tank 2. The telescopic plate 83 is located at the outlet for opening and closing the outlet. The image analysis device 4 is located at the bottom of the electric clamp 81 and faces the bottom surface of the culture tank 9, or the image analysis device 4 is located at the bottom surface of the electric clamp in the culture tank 9 and faces the top of the culture tank 9.

[0088] The data transmission device 5, electric clamp 81, moving device 82, and telescopic plate 83 are electrically connected to each other.

[0089] When the replenishment device 8 is running, the image analysis device 4 is activated. If the new packing material identified by the image analysis device 4 does not meet the requirements, the moving device 82 moves until it reaches the new packing material that meets the requirements and then stops moving. The electric clamp 81 picks up the target new packing material, and the moving device 82 moves the electric clamp 81 above the telescopic plate 83 and releases the new packing material. The telescopic plate 83 retracts, thereby opening the outlet of the cultivation tank 9, allowing the new packing material to enter the MBBR water tank 2, realizing the replenishment of the packing material in the MBBR water tank 2. The bottom surface of the cultivation tank 9 is divided into several squares, and the electric clamp 81 pre-places the new packing material one in each square. Each square on the bottom surface of the cultivation tank 9 corresponds to an image analysis device 4. The image analysis devices 4 work simultaneously and can quickly respond to control the moving device 82 to move the electric clamp 81 and pick up the new packing material. This allows for the rapid replacement of the corresponding quality of packing material 3, accurately dispensing the required quantity, and ensuring the continuous and effective purification of the MBBR water tank 2.
