Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an online monitoring and pretreatment device for wastewater. Background Technology

[0002] In the field of water treatment, especially in the treatment of industrial wastewater, effective online monitoring and pretreatment are crucial. Pollutants in wastewater, such as chemical oxygen demand (COD), ammonia nitrogen (NH3-N), and suspended solids, need to be accurately monitored and controlled to meet discharge standards. Traditional wastewater treatment systems typically employ static monitoring and manual adjustment of aeration rates, which is not only inefficient but also makes real-time control of wastewater quality difficult.

[0003] In recent years, with the development of automation technology, some automated wastewater treatment systems have been proposed. These systems monitor wastewater parameters in real time through online monitoring devices and automatically adjust the treatment process, such as aeration rate, based on the monitoring results. However, these systems often neglect the issue of removing suspended solids during wastewater treatment. During aeration, suspended solids are carried to the water surface by the rising of air bubbles, forming a scum layer. This scum needs to be effectively removed to prevent it from re-entering the treatment process and affecting the treatment effect.

[0004] While some patents propose methods for cleaning suspended solids from the water surface using robotic arms or rotating brushes, these methods typically require additional electricity, increasing the system's energy consumption and maintenance costs. Therefore, developing a device that utilizes the energy generated during aeration to drive the cleaning of suspended solids would be an innovative solution, not only improving wastewater treatment efficiency but also reducing energy consumption and operating costs.

[0005] To address this problem, the present invention provides a wastewater online monitoring and pretreatment device. This device can automatically adjust the aeration rate based on the online monitoring results, and use the power of rising bubbles to drive an automatic retrieval mechanism during the aeration process to achieve the removal of suspended solids. Summary of the Invention

[0006] The purpose of this invention is to provide an online monitoring and pretreatment device for wastewater in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution:

A spring connects the sealing ball to the upper baffle plate. A connecting rod is fixed to the top of the sealing ball, and a conical block with a smaller bottom diameter is fixed to the end of the connecting rod. The diameter of the top of the conical block is the same as the inner diameter of the aeration pipe. When the sealing ball is in contact with the inner wall of the lower baffle plate, the top side of the conical block is flush with the top of the aeration pipe.

[0015] Furthermore, the air inlet pipe and the vent pipe are located on opposite sides of the air box, the air chamber is cylindrical, and the linkage mechanism includes a mounting rod rotatably mounted on the top of the air box and located on the central axis of the air chamber and the central axis of the wastewater tank. The bottom end of the mounting rod movably penetrates the air box and is rotatably mounted on the inner wall of the air chamber. At least two arc-shaped blades are fixed on the mounting rod and arranged in an array. Several arc-shaped blades are located inside the air chamber. The side of the arc-shaped blades facing away from the mounting rod is in contact with the side wall of the air chamber. The collection mechanism is mounted on the mounting rod.

[0016] Furthermore, the number of collection mechanisms is not less than one and they are arranged in a rotating array around the central axis of the mounting rod. The collection mechanism includes a retrieval part and a recovery part. The retrieval part includes two horizontally arranged and vertically distributed device rods. Two conveyor wheels are fixedly sleeved on each of the two device rods. An integral conveyor belt is sleeved on the four conveyor wheels. The conveyor belt is arranged at an angle. Several evenly distributed retrieval plates are fixed on the outer periphery of the conveyor belt. A support frame is fixed at the top of the mounting rod. One end of the two device rods on the same side is rotatably mounted on the support frame. An annular face gear is fixed on the inner wall of the wastewater pool. A hobbing gear that meshes with the face gear is fixedly sleeved on the other end of the lower device rod. A bearing member erected on the top of the wastewater pool is installed on the other end of the upper device rod.

[0018] Furthermore, the recycling section includes a recycling plate fixed on the support frame and located below the top of the conveyor belt. The top side of the recycling plate is constructed with a recycling channel, which penetrates the end of the recycling plate away from the central axis of the wastewater tank. The bottom side of the recycling channel is inclined and the end penetrating the recycling plate is lower. The bottom of the recycling plate is ball-connected with a plurality of evenly distributed rolling balls, and the plurality of rolling balls roll inside the limiting groove.

[0019] Furthermore, an annular collection tank is fixedly fitted on the outside of the wastewater tank, a collection trough is constructed on the top of the collection tank, a discharge channel connected to the collection trough is fixed on the outer periphery of the collection tank, a connecting plate is fixed on the bearing block, and a scraper that fits against the inner wall of the collection trough is fixed at the bottom end of the connecting plate.

[0020] Furthermore, several evenly distributed baffles are fixed on the mounting rod. The baffles are located above the aeration pipe and below the collection mechanism. The baffles are inclined and have a blade-like outer surface.

[0021] Furthermore, both the conveyor belt and the salvage plate are constructed with a number of water seepage holes.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This solution uses an online monitoring device to monitor the concentration of pollutants in wastewater in real time and automatically adjusts the aeration rate, enabling more precise control of the wastewater treatment process and improving treatment efficiency. The energy generated during aeration is used to drive the suspended solids collection mechanism, eliminating the need for additional electricity and thus reducing the overall system's energy consumption. By reducing energy consumption and maintenance costs and improving treatment efficiency, the economic benefits of the wastewater treatment facility are enhanced.

[0024] This invention automates the removal of suspended solids, reduces manual intervention, and improves the convenience and safety of operation.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] This embodiment provides a wastewater online monitoring and pretreatment device, mainly used to address the issue that during wastewater aeration, suspended solids are carried to the water surface by the rising of air bubbles, forming a scum layer. This scum needs to be effectively removed to prevent it from re-entering the treatment process and affecting the treatment effect. Current devices use robotic arms or rotating brushes to clean the suspended solids on the water surface, but these methods typically require additional electricity, increasing the system's energy consumption and maintenance costs. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-11 Please provide a detailed explanation:

[0041] Example 1: A wastewater online monitoring and pretreatment device, comprising a wastewater tank 1, an aeration mechanism 2, a collection mechanism 3 for collecting suspended solids, and a linkage mechanism 4, wherein:

[0042] The wastewater tank 1 is equipped with an online monitoring device that can monitor various indicators of the wastewater in real time, such as chemical oxygen demand and ammonia nitrogen, to ensure precise control of the wastewater treatment process. The online monitoring device is based on sensor technology and automatically samples and analyzes wastewater samples. It should be noted that the online monitoring technology for wastewater is a mature technology and is used in sewage treatment plants and other places. This solution will not go into too much detail. The top of the wastewater tank 1 is open and the bottom of the wastewater tank 1 is connected to a drain pipe 11 for the discharge of treated wastewater. The cross-section of the wastewater tank 1 is circular, which optimizes space utilization and treatment efficiency.

[0043] The aeration mechanism 2 is installed on the wastewater tank 1 and is used to aerate the interior of the wastewater tank 1. The aeration rate of the aeration mechanism 2 is automatically adjusted according to the real-time monitoring data of the online monitoring device. This design makes the aeration process more flexible and can adjust the aeration rate according to actual needs, which saves energy and improves treatment efficiency.

[0044] During the treatment process, the suspended solids inside the wastewater tank 1 need to be effectively removed to prevent them from re-entering the treatment process and affecting the treatment effect. For this purpose, the device is equipped with a collection mechanism 3, which is specifically used to salvage and collect the suspended solids inside the wastewater tank 1.

[0045] The linkage mechanism 4 is located inside the wastewater tank 1 and is used to transfer the energy generated during aeration to the collection mechanism 3, thereby driving the collection mechanism 3 to perform suspended solids collection work. This process does not require additional electric drive, which greatly reduces energy consumption and maintenance costs.

[0046] Please see Figure 2 , Figure 3 and Figure 8 The aeration mechanism 2 includes a blower 21 and an air box 22, which is designed to deliver air into the wastewater tank 1 to promote the biodegradation of organic matter in the wastewater. The blower 21 is located on one side of the wastewater tank 1 for easy operation and maintenance. The air box 22 is fixed to the inner wall of the wastewater tank 1 and the internal structure of the air box 22 has a sealed air chamber 23. This design helps to maintain stable gas pressure and reduce gas leakage.

[0047] An air inlet pipe 24, which runs through the wastewater tank 1, connects the air chamber 23 to the air outlet of the blower 21, ensuring that the gas can be directly and efficiently delivered to the aeration area. A support rod is installed on the inner wall of the wastewater tank 1, and an annular pipe 25 is installed on the top of the support rod. An air vent pipe 26 connects the annular pipe 25 to the air chamber 23. Several aeration pipes 27 arranged in an array are installed on the top of the annular pipe 25. This structural design helps to evenly distribute the gas. This design allows the gas to be released from multiple points, increasing the gas-liquid contact area and improving the oxygen transfer efficiency. A check valve component 28 is installed inside the aeration pipe 27 to prevent wastewater from flowing into the annular pipe 25, ensuring the continuity and efficiency of the aeration process.

[0048] The backflow prevention component 28 is a key part of the aeration mechanism 2. Its ingenious design and crucial function are primarily to prevent wastewater from flowing back into the aeration pipe 27. (See also...) Figure 3 The check valve assembly 28 includes two baffle plates 281 fixed on the inner wall of the aeration pipe 27. A sealing ball 282 is movably disposed between the two baffle plates 281. The diameter of the sealing ball 282 is larger than the inner diameter of the baffle plates 281 and smaller than the inner diameter of the aeration pipe 27. This size selection ensures that the sealing ball 282 can move flexibly between the baffle plates 281 without slipping out of the aeration pipe 27.

[0049] A spring 283 connects the blocking ball 282 to the upper baffle plate 281. The spring 283 provides elasticity to the blocking ball 282, ensuring that it fits against the inner wall of the lower baffle plate 281 when not aerating, preventing wastewater from flowing into the annular pipe 25. During aeration, the air pressure lifts the blocking ball 282, ensuring aeration. A connecting rod 284 is fixed to the top of the blocking ball 282, and a conical block 285 with a smaller bottom diameter is fixed to the end of the connecting rod 284. The diameter of the top of the conical block 285 is the same as the inner diameter of the aeration pipe 27. When the blocking ball 282 fits against the inner wall of the lower baffle plate 281, the top side of the conical block 285 is flush with the top of the aeration pipe 27. This design prevents wastewater from entering the interior of the aeration pipe 27, reduces maintenance requirements, and improves the reliability and efficiency of the entire aeration mechanism 2.

[0050] The ingenious design of the linkage mechanism 4 ensures that the energy generated during aeration is effectively transferred to the collection mechanism 3, thereby driving it to collect suspended solids. Please refer to [link / reference needed] for details. Figure 2 , Figure 8 and Figure 9 The air inlet pipe 24 and the air outlet pipe 26 are located on opposite sides of the air box 22. This layout allows the gas to be evenly distributed into the air chamber 23. The air chamber 23 is cylindrical, which is conducive to the flow and distribution of gas.

[0051] The linkage mechanism 4 includes a mounting rod 41 rotatably mounted on the top of the gas box 22 and located on the central axis of the gas cavity 23 and the central axis of the wastewater tank 1, ensuring the directness and efficiency of energy transfer. The bottom end of the mounting rod 41 movably passes through the gas box 22 and is rotatably mounted on the inner wall of the gas cavity 23. At least two arc-shaped blades 42 are fixed on the mounting rod 41 in an array. These arc-shaped blades 42 are all located inside the gas cavity 23. Their design helps to capture and convert the energy generated by the gas flow. The side of the arc-shaped blades 42 facing away from the mounting rod 41 is in contact with the side wall of the gas cavity 23. This layout not only stabilizes the blades but also maximizes the efficiency of energy conversion. The collection mechanism 3 is mounted on the mounting rod. On 41, this design allows the collection mechanism 3 to receive power directly from the linkage mechanism 4, realizing automated retrieval operations. The entire linkage mechanism 4 cleverly utilizes the airflow energy during the aeration process, converting the airflow energy into mechanical energy through the arc-shaped blade 42, thereby driving the collection mechanism 3 to perform suspended solids retrieval work without additional energy input. Specifically, the blower 21 vents air into the air chamber 23 through the air inlet pipe 24, and the gas pushes the arc-shaped blade 42 to rotate, thereby causing the mounting rod 41 to rotate. Then, the gas enters the interior of the annular pipe 25 from the vent pipe 26, and finally sprays out from the aeration pipe 27. While aerating the wastewater, it can also drive the mounting rod 41 to rotate.

[0052] In this embodiment, please refer to Figure 2 , Figure 4 , Figure 7 , Figure 9 and Figure 10 The collection mechanism 3, as the core part of the device, consists of at least one unit. These units are arranged in a rotating array around the central axis of the mounting rod 41 to ensure that the entire surface of the wastewater pool 1 is effectively covered. Each collection mechanism 3 includes a retrieval section 31 and a recovery section 32, which work together to achieve the retrieval and recovery of suspended solids.

[0053] The salvage unit 31 includes two horizontally arranged and vertically distributed device rods 311. Two conveyor wheels 312 are fixedly mounted on each of the two device rods 311. An integrated conveyor belt 313 is mounted on the four conveyor wheels 312. The conveyor belt 313 is arranged at an angle, which is conducive to the collection and transfer of suspended objects during the salvage process. Several evenly distributed salvage plates 314 are fixed on the outer periphery of the conveyor belt 313. These salvage plates 314 are responsible for directly contacting the water surface to salvage suspended objects. It should be noted that the bottom end of the conveyor belt 313 is below the water surface, which can ensure the salvage efficiency of suspended objects.

[0054] To ensure the stability and operational flexibility of the retrieval unit 31, a support frame 43 is fixed to the top of the mounting rod 41. One end of each of the two mounting rods 311 is rotatably mounted on the support frame 43 on the same side. A ring-shaped face gear 315 is fixed to the inner wall of the wastewater tank 1. A hobbing gear 316, meshing with the face gear 315, is fixedly fitted onto the other end of the lower mounting rod 311. This gear combination ensures that the movement of the retrieval unit 31 is synchronized with the rotation of the wastewater tank 1, improving retrieval efficiency. Specifically, when the mounting rod 41 drives the support frame 43 to rotate, the mounting rod 311 and the conveyor belt 313... The device will rotate accordingly. At the same time, when the device rod 311 rotates around the mounting rod 41, the hobbing gear 316 at one end of the lower device rod 311 will roll on the face gear 315, thereby causing the device rod 311 to rotate. Driven by the transmission wheel 312, the transmission belt 313 will rotate, and the retrieval plate 314 will perform the retrieval of suspended objects. It should be noted that in order to ensure the transmission efficiency, teeth are evenly arranged on the outer periphery of the transmission wheel 312, and evenly distributed tooth grooves are opened through the transmission belt 313. The teeth are movably inserted into the tooth grooves, which can ensure the transmission efficiency of the transmission wheel 312.

[0055] A support member 317 is installed on the other end of the upper device rod 311 and is erected on the top of the wastewater tank 1. The setting of the support member 317 can ensure the stability of the collection mechanism 3 when it rotates with the mounting rod 41.

[0056] The construction and function of the support component 317 are crucial to the smooth operation of the entire system. For details, please refer to [link to relevant documentation]. Figure 5 , Figure 6 and Figure 9 The carrier 317 includes a carrier block 3171 hinged to the other end of the device rod 311. The hinged connection does not affect the rotation of the device rod 311. The bottom of the carrier block 3171 is spherically connected to several evenly distributed rolling balls 3172. The top of the wastewater pool 1 is constructed with an annular limiting groove 12. The rolling balls 3172 roll inside the limiting groove 12. The limiting groove 12 not only provides a stable moving path for the carrier block 3171, but also limits its moving range, preventing the carrier 317 from deviating or derailing during operation. This design allows the carrier 317 to move smoothly and continuously along the edge of the wastewater pool 1 to perform the salvage task.

[0057] Furthermore, the recovery unit 32 is a key component of the device responsible for recovering and processing the salvaged suspended solids. Please refer to [link to relevant documentation]. Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11The recycling unit 32 includes a recycling plate 321 fixed on the support frame 43 and located below the top of the conveyor belt 313. This layout allows the recycling unit 32 to directly receive suspended matter transported from the conveyor belt 313, which facilitates the next step of processing.

[0058] The top side of the recycling plate 321 is constructed with a recycling channel 322, which runs through the end of the recycling plate 321 away from the central axis of the wastewater tank 1. The bottom side of the recycling channel 322 is inclined and the end that runs through the recycling plate 321 is lower. This design facilitates the smooth sliding of suspended solids along the recycling channel 322 and finally discharges them from the lower end of the recycling plate 321, ensuring the continuity and efficiency of the recycling process.

[0059] To ensure the stability and mobility of the recycling plate 321, several evenly distributed rolling balls 323 are connected to the bottom ball of the recycling plate 321. The rolling balls 323 roll inside the limiting groove 12. The limiting groove 12 not only provides a stable rolling path for the rolling balls 323, but also limits the range of movement of the recycling plate 321, preventing it from deviating or derailing during operation.

[0060] Example 2: Example 2 is a further optimization of Example 1, enhancing the device's collection and discharge functions. For details, please refer to... Figure 7 An annular collection pool 13 is fixedly fitted on the outside of the wastewater pool 1. This design expands the collection capacity of the device and provides a dedicated storage area for the suspended solids that are retrieved. A collection trough 14 is constructed on the top of the collection pool 13. This is a space for temporarily storing the suspended solids retrieved from the wastewater pool 1. This design allows the suspended solids to be centrally stored before being further processed or removed, which is convenient for management.

[0061] In order to discharge suspended solids in the collection tank 14, a discharge channel 15 connected to the collection tank 14 is fixed on the outer periphery of the collection tank 13. A connecting plate 3173 is fixed on the bearing block 3171. A scraper 3174 that fits against the inner wall of the collection tank 14 is fixed at the bottom end of the connecting plate 3173. The function of the scraper 3174 is to scrape the suspended solids into the discharge channel 15 and discharge them as the mounting rod 41 continues to rotate when they are transferred to the collection tank 14, thus ensuring the thoroughness and efficiency of the collection process.

[0062] In summary, Embodiment 2 achieves effective collection and discharge of suspended solids by adding an annular collection tank 13 outside the wastewater tank 1, along with a corresponding collection trough 14 and discharge channel 15. Simultaneously, the design of the connecting plate 3173 and scraper 3174 ensures that suspended solids can be smoothly transferred from the collection trough 14 to the discharge channel 15. This optimization not only improves the collection efficiency of the device but also makes the entire discharge process smoother and more controllable, further enhancing the automation level and overall performance of wastewater treatment.

[0063] Example 3: Please refer to Figure 9 and Figure 11 Example 3 is a further optimization of Example 1. Several evenly distributed baffles 411 are fixed on the mounting rod 41. The main function of the baffles 411 is to disrupt the airflow, increase the contact area and contact time between the bubbles and the wastewater during aeration, thereby improving the oxygen transfer efficiency and aeration uniformity. The baffles 411 are all located above the aeration pipe 27 and below the collection mechanism 3. The baffles 411 are inclined and have a blade-like outer structure. This layout can effectively disrupt the straight flow of the bubbles when they rise, making the distribution of bubbles in the wastewater more uniform and enhancing the mixing effect between the bubbles and the wastewater. In addition, the blade-like outer structure of the baffles 411 helps to cut the bubbles and form smaller bubbles, further improving the oxygen transfer efficiency.

[0064] Through this optimized design, the baffle 411 not only improves aeration efficiency but also helps reduce energy consumption and improve the performance of the entire wastewater treatment system. This design cleverly utilizes the principles of fluid mechanics. By setting up the baffle 411, the interaction between bubbles and wastewater is enhanced, achieving more efficient oxygen transfer and mixing of suspended solids, thus providing better conditions for subsequent suspended solids removal.

[0065] Example 4: Example 4 is a further optimization of Example 1. Please refer to [link / reference]. Figure 4 and Figure 8 Both the conveyor belt 313 and the retrieval plate 314 have several perforation holes 318. The perforation holes 318 are introduced to improve the water discharge efficiency during the retrieval process and ensure that the water in the retrieved suspended matter can be effectively removed. When the conveyor belt 313 is running and carrying the suspended matter retrieved by the retrieval plate 314, the perforation holes 318 allow water to gradually seep out during the process of transporting the suspended matter to the collection area, reducing the water content of the retrieved matter. In this way, the suspended matter that arrives at the recycling section 32 is drier and easier to process and dispose of, such as compression, incineration or use as fertilizer.

[0066] In addition, the design of the drainage hole 318 helps to reduce the load on the conveyor belt 313, reduce its operating resistance, thereby reducing energy consumption and improving the efficiency of the entire device. This design also reduces corrosion problems that may be caused by moisture residue and extends the service life of the equipment.

[0067] The operation of this device begins with the online monitoring system inside wastewater tank 1. This system monitors key indicators in the wastewater, such as chemical oxygen demand (COD) and ammonia nitrogen, in real time to ensure precise control of the treatment process. This monitoring data is used to automatically adjust the aeration rate of the aeration mechanism 2, making the aeration process more flexible. The aeration rate can be adjusted according to actual needs, saving energy and improving treatment efficiency. The specific operating method is as follows:

[0068] During the aeration process, the blower 21 vents air into the air chamber 23 through the air inlet pipe 24. The gas drives the arc-shaped blade 42 to rotate, thereby causing the mounting rod 41 to rotate and drive the entire collection mechanism 3 to work. At the same time, the gas enters the interior of the annular pipe 25 from the air inlet pipe 26 and is finally sprayed out from the aeration pipe 27. While aerating the wastewater, it can also drive the mounting rod 41 to rotate, realizing the function of the linkage mechanism 4.

[0069] Meanwhile, suspended solids inside wastewater pool 1 are collected by collection mechanism 3. The collection part 31 includes two device rods 311, with a conveyor wheel 312 and a conveyor belt 313 on them. A collection plate 314 is fixed on the outer periphery of the conveyor belt 313, which is responsible for directly contacting the water surface to collect suspended solids. The recovery part 32 includes a recovery plate 321, a recovery channel 322 on the top side, and a ball connected to a rolling ball 323 at the bottom, all of which roll inside the limiting slide groove 12 to ensure the stability and flexibility of the recovery plate 321.

[0070] When suspended matter is transported to the recycling section 32 by the conveyor belt 313, the design of the recycling channel 322 allows the suspended matter to slide down smoothly and be discharged, completing the recycling process. The scraper 3174 at the bottom of the connecting plate 3173 fits against the inner wall of the collection tank 14, ensuring that the suspended matter can be smoothly transferred from the collection tank 14 to the discharge channel 15 for discharge.

[0071] In addition, the design of the baffle plate 411 disrupts the airflow, increases the contact area and contact time between the bubbles and the wastewater, improves the oxygen transfer efficiency and aeration uniformity, and the permeation holes 318 are set on the conveyor belt 313 and the scooping plate 314 to improve the water discharge efficiency and ensure that the water in the scooped suspended solids can be effectively removed.
