Description

Technical Field

[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), suspended solids, etc., need to be accurately monitored and controlled to meet emission standards. Traditional wastewater treatment systems usually use static monitoring and manual adjustment of aeration volume, which is not only inefficient, but also difficult to achieve real-time control of wastewater quality.

[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 volume, according to the monitoring results. However, these systems often ignore the problem of cleaning suspended solids in the wastewater treatment process. During the aeration process, due to the rising effect of bubbles, suspended solids will be brought to the water surface to form a scum layer. These scums need to be effectively removed to prevent them from re-entering the treatment process and affecting the treatment effect.

[0004] Although some patents propose methods of using mechanical arms or rotating brushes to clean suspended solids on the water surface, these methods usually require additional electric drive, increasing the energy consumption and maintenance costs of the system.

DETAILED DESCRIPTION

[0023] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The present embodiment provides a wastewater online monitoring pretreatment device, which is mainly used to solve the problem that during the aeration process of wastewater, due to the rising effect of bubbles, suspended matter will be brought to the water surface to form a scum layer. These scum need to be effectively removed to prevent them from re-entering the treatment process and affecting the treatment effect. At present, some devices use mechanical arms or rotating brushes to clean the suspended matter on the water surface, but these methods usually require additional power drive, which increases the energy consumption and maintenance cost of the system. The following technical solutions are provided, which will be combined with Figure 1-Figure 11 Make a detailed description: Embodiment 1: A wastewater online monitoring pretreatment device comprises a wastewater pool 1, an aeration mechanism 2, a collection mechanism 3 for collecting suspended matter, and a linkage mechanism 4, wherein: An online monitoring device is installed inside the wastewater pool 1. The online monitoring device can monitor various indicators of wastewater in real time, such as chemical oxygen demand, ammonia nitrogen, etc., to ensure accurate 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 of wastewater is currently a mature technology and is used in sewage treatment plants and other places. This solution will not be described in detail. The top structure of the wastewater pool 1 is open and the bottom of the wastewater pool 1 is connected to a drain pipe 11 for draining the treated wastewater. The cross-section of the wastewater pool 1 is circular, which optimizes space utilization and treatment efficiency. 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 amount of the aeration mechanism 2 is automatically adjusted according to the real-time monitoring data of the online monitoring device. Such a design makes the aeration process more flexible and can adjust the aeration amount according to actual needs, which saves energy and improves the treatment efficiency. During the treatment process, the suspended matter inside the wastewater pool 1 needs 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 matter inside the wastewater pool 1; The linkage mechanism 4 is arranged 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 matter salvage and collection work. This process does not require additional electric drive, which greatly reduces energy consumption and maintenance costs.

[0025] See also Figure 2 , Figure 3 and Figure 8 The aeration mechanism 2 includes a blower 21 and an air box 22, which is intended to transport air into the wastewater tank 1 to promote the biodegradation of organic matter in the wastewater. The blower 21 is arranged on one side of the wastewater tank 1 for easy operation and maintenance. The air box 22 is fixed on the inner wall of the wastewater tank 1 and has a closed air cavity 23 inside the air box 22. Such a design helps to maintain the stability of the gas pressure and reduce gas leakage. An air inlet pipe 24 that runs through the wastewater tank 1 is connected between the air cavity 23 and the air outlet end of the blower 21, ensuring that the gas can be directly and efficiently transported to the aeration area. A support rod is provided on the inner wall of the wastewater tank 1, and a ring-shaped tube 25 is installed on the top of the support rod. A ventilation pipe 26 is connected between the ring-shaped tube 25 and the air cavity 23. A plurality of aeration tubes 27 distributed in an array are installed on the top of the ring-shaped tube 25. Such a structural design is conducive to uniform distribution of gas. This design enables gas to be released from multiple points, increases the gas-liquid contact area, and improves the oxygen transfer efficiency. A check assembly 28 is provided inside the aeration tube 27 to prevent wastewater from flowing into the inside of the ring-shaped tube 25, thereby ensuring the continuity and efficiency of the aeration process.

[0026] The check assembly 28 is a key part of the aeration mechanism 2. It is delicately designed and has important functions. It is mainly used to prevent wastewater from flowing back into the aeration pipe 27. Figure 3 The check assembly 28 includes two baffle plates 281 fixed on the inner wall of the aeration tube 27, and a blocking ball 282 is movably arranged between the two baffle plates 281. The diameter of the blocking ball 282 is larger than the inner diameter of the baffle plates 281 and smaller than the inner diameter of the aeration tube 27. Such a size selection ensures that the blocking ball 282 can move flexibly between the baffle plates 281 and will not slip out of the aeration tube 27; A spring 283 is connected between the sealing ball 282 and the baffle plate 281 located above. The design of the spring 283 can provide elasticity for the sealing ball 282. When there is no aeration, the sealing ball 282 is ensured to fit against the inner wall of the baffle plate 281 below to prevent wastewater from flowing into the annular tube 25. During aeration, the air pressure can lift up the sealing ball 282 to ensure aeration. A connecting rod 284 is fixed to the top of the sealing ball 282. 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 tube 27. When the sealing ball 282 fits against the inner wall of the baffle plate 281 located below, the top side of the conical block 285 is flush with the top of the aeration tube 27. This design can prevent wastewater from entering the interior of the aeration tube 27, reduces the need for maintenance, and improves the reliability and efficiency of the entire aeration mechanism 2.

[0027] The ingenious design of the linkage mechanism 4 ensures that the energy generated during the aeration process can be effectively transferred to the collection mechanism 3, thereby driving it to salvage and collect suspended matter. For details, please refer to Figure 2 , Figure 8 and Fig. 9 The air inlet pipe 24 and the vent pipe 26 are respectively located on opposite sides of the air box 22. This layout allows the gas to be evenly distributed into the air cavity 23. The air cavity 23 is cylindrical, which is conducive to the flow and distribution of the gas; The linkage mechanism 4 includes a mounting rod 41 which is rotatably mounted on the top of the gas box 22 and is 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 penetrates the gas box 22 and is rotatably mounted on the inner wall of the gas cavity 23. No less than two arc-shaped blades 42 distributed in an array are fixed on the mounting rod 41. Several arc-shaped blades 42 are 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 blade 42 facing away from the mounting rod 41 is in contact with the side wall of the gas cavity 23. Such a layout not only stabilizes the blade, but also maximizes the efficiency of energy conversion. The collecting mechanism 3 is mounted on the mounting rod 41, this design enables the collecting mechanism 3 to directly receive power from the linkage mechanism 4 to realize automatic salvaging operations. The design of the entire linkage mechanism 4 cleverly utilizes the airflow energy during the aeration process, and converts the airflow energy into mechanical energy through the arc-shaped blades 42, thereby driving the collecting mechanism 3 to salvage the suspended matter without the need for additional energy input. Specifically, the blower 21 ventilates the interior of the air cavity 23 through the air inlet pipe 24, and the gas will push the arc-shaped blades 42 to rotate, thereby rotating the mounting rod 41, and then the gas enters the interior of the annular tube 25 from the ventilation pipe 26, and finally is ejected from the aeration pipe 27. While aerating the wastewater, it can also drive the mounting rod 41 to rotate.

[0028] In this example, see Figure 2 , Figure 4 , Figure 7 , Fig. 9 and Fig.10 The collecting mechanism 3, as the core part of the device, is composed of no less than one unit, which is distributed in a rotating array with the central axis of the mounting rod 41 as the center, ensuring that the water surface of the entire wastewater pool 1 can be effectively covered. Each collecting mechanism 3 includes a salvaging part 31 and a recovery part 32, which work together to achieve the salvage and recovery of suspended matter, wherein: The salvage part 31 includes two horizontally arranged device rods 311 distributed up and down, two transmission wheels 312 are fixedly sleeved on the two device rods 311, and an integrated conveyor belt 313 is sleeved on the four transmission wheels 312. The conveyor belt 313 is arranged in an inclined direction. Such a layout is conducive to the collection and transfer of suspended matter during the salvage process. A number of evenly distributed salvage plates 314 are fixed on the outer peripheral side of the conveyor belt 313. These salvage plates 314 are responsible for directly contacting the water surface to salvage the suspended matter. It should be noted that the bottom end of the conveyor belt 313 is located below the water surface, which can ensure the salvage efficiency of the suspended matter. In order to ensure the stability and operational flexibility of the salvage part 31, a support frame 43 is fixed to the top of the installation rod 41, and one end of the same side of the two device rods 311 is rotatably mounted on the support frame 43. An annular face gear 315 is fixed to the inner wall of the wastewater tank 1, and a roller gear 316 meshing with the face gear 315 is fixedly sleeved on the other end of the device rod 311 located below. This gear combination ensures that the movement of the salvage part 31 is synchronized with the rotation of the wastewater tank 1, thereby improving the salvage efficiency. That is, when the installation rod 41 drives the support frame 43 to rotate, the device rod 311 and the transmission belt 313 are in a state of being ... The conveyor belt 313 is driven by the conveyor wheel 312, and the conveyor belt 313 is driven by the conveyor wheel 312. .... The conveyor belt 313 is driven by the conveyor wheel 312. The conveyor belt 313 is driven by the conveyor wheel 312. A bearing member 317 mounted on the top of the wastewater pool 1 is installed on the other end of the upper device rod 311 . The arrangement of the bearing member 317 can ensure the stability of the collection mechanism 3 when it rotates with the installation rod 41 .

[0029] The construction and function of the bearing 317 is critical to the smooth operation of the entire system. For details, see Figure 5 , Figure 6 and Fig. 9The supporting member 317 includes a supporting block 3171 hinged on the other end of the device rod 311. The hinged manner can not affect the rotation of the device rod 311. The bottom ball of the supporting block 3171 is connected with a plurality of evenly distributed rolling balls 3172. The top of the wastewater tank 1 is constructed with an annular limiting groove 12. The plurality of rolling balls 3172 roll inside the limiting groove 12. The limiting groove 12 not only provides a stable moving path for the supporting block 3171, but also limits its moving range to prevent the supporting member 317 from being offset or derailed during operation. Such a design enables the supporting member 317 to move smoothly and continuously along the edge of the wastewater tank 1 to perform salvage tasks.

[0030] Furthermore, the recovery unit 32 is a key part of the device responsible for recovering and processing the salvaged suspended matter. Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 The recovery part 32 includes a recovery plate 321 fixed on the support frame 43 and located below the top of the conveyor belt 313. Such a layout enables the recovery part 32 to directly receive the suspended matter transported from the conveyor belt 313, which provides convenience for the next step of processing; The top side of the recovery plate 321 is configured with a recovery channel 322, which penetrates one end of the recovery plate 321 away from the central axis of the wastewater tank 1, and the bottom side of the recovery channel 322 is inclined and the end penetrating the recovery plate 321 is lower. This design is conducive to the suspended matter sliding down the recovery channel 322 smoothly, and finally discharged from a lower position at one end of the recovery plate 321, thereby ensuring the continuity and efficiency of the recovery process; In order to ensure the stability and flexibility of the recovery plate 321, the bottom ball of the recovery plate 321 is connected to a number of evenly distributed rolling balls 323, and the several rolling balls 323 roll inside the limiting slide groove 12. The limiting slide groove 12 not only provides a stable rolling path for the rolling balls 323, but also limits the moving range of the recovery plate 321 to prevent it from deviating or derailing during operation.

[0031] Embodiment 2: Embodiment 2 is a further optimization of Embodiment 1, which enhances the collection and discharge functions of the device. For details, please refer to Figure 7 The outer fixed sleeve of the wastewater tank 1 is provided with an annular collection tank 13. This design expands the collection capacity of the device, so that the salvaged suspended matter has a special storage area. The top of the collection tank 13 is constructed with a collection tank 14, which is a space for temporarily storing the suspended matter salvaged from the wastewater tank 1. This design allows the suspended matter to be centrally stored before being further processed or removed, which is convenient for management; In order to discharge the suspended matter in the collecting tank 14, a discharge channel 15 connected to the collecting tank 14 is fixed on the outer peripheral side of the collecting pool 13, a connecting plate 3173 is fixed on the supporting block 3171, and a scraper 3174 that fits the inner wall of the collecting tank 14 is fixed to the bottom end of the connecting plate 3173. The function of the scraper 3174 is that when the suspended matter is transmitted to the collecting tank 14, as the mounting rod 41 continues to rotate, the scraper 3174 scrapes it into the discharge channel 15 for discharge, thereby ensuring the thoroughness and efficiency of the collection process.

[0032] In summary, in the second embodiment, an annular collection tank 13, as well as a matching collection tank 14 and a discharge channel 15 are added to the outside of the wastewater tank 1 to achieve effective collection and discharge of suspended matter. At the same time, through the design of the connecting plate 3173 and the scraper 3174, it is ensured that the suspended matter can be smoothly transferred from the collection tank 14 to the discharge channel 15 and discharged. This optimization not only improves the collection efficiency of the device, but also makes the entire discharge process smoother and more controllable, further improving the automation level and overall performance of wastewater treatment.

[0033] Example 3: Please refer to Fig. 9 and Fig.11 , Embodiment 3 is a further optimization of Embodiment 1. A plurality of evenly distributed spoilers 411 are fixed on the mounting rod 41. The main function of the spoiler 411 is to disrupt the airflow and increase the contact area and contact time between the bubbles and the wastewater during the aeration process, thereby improving the oxygen transfer efficiency and the aeration uniformity. The plurality of spoilers 411 are located above the aeration tube 27 and below the collecting mechanism 3. The spoiler 411 is inclined and the outer side is configured as a knife surface. Such a layout can effectively destroy the linear flow of the bubbles when they rise, so that the distribution of the bubbles in the wastewater is more even, and the mixing effect of the bubbles and the wastewater is enhanced. In addition, the outer side of the spoiler 411 is configured as a knife surface. This design helps to cut the bubbles and form smaller bubbles, further improving the oxygen transfer efficiency.

[0034] Through this optimized design, spoiler 411 not only improves aeration efficiency, but also helps to reduce energy consumption and improve the performance of the entire wastewater treatment system. This design cleverly utilizes the principles of fluid mechanics. Through the setting of spoiler 411, the interaction between bubbles and wastewater is enhanced, achieving more efficient oxygen transfer and mixing of suspended matter, and providing better conditions for subsequent suspended matter salvage work.

[0035] Embodiment 4: Embodiment 4 is a further optimization of Embodiment 1. Please refer to Figure 4 and Figure 8A plurality of seepage holes 318 are formed through the conveyor belt 313 and the salvage plate 314. The seepage holes 318 are introduced to improve the water discharge efficiency during the salvage process and ensure that the water in the salvaged suspended matter can be effectively removed. When the conveyor belt 313 is running and carrying the suspended matter salvaged by the salvage plate 314, the seepage holes 318 allow the water to gradually seep out during the process of the suspended matter being transported to the collection area, thereby reducing the water content of the salvaged matter. In this way, the suspended matter reaching the recovery part 32 is drier, which is convenient for subsequent processing and disposal, such as compression, incineration or use as fertilizer.

[0036] In addition, the design of the water seepage holes 318 also helps to reduce the load on the conveyor belt 313 and reduce its running resistance, thereby reducing energy consumption and improving the efficiency of the entire device. This design also reduces corrosion problems that may be caused by residual moisture and extends the service life of the equipment.

[0037] The operation of this device starts with the online monitoring devices inside the wastewater pool 1. They monitor the key indicators such as chemical oxygen demand and ammonia nitrogen in the wastewater in real time to ensure accurate control of the treatment process. These monitoring data are used to automatically adjust the aeration volume of the aeration mechanism 2, making the aeration process more flexible. The aeration volume can be adjusted according to actual needs, which saves energy and improves treatment efficiency. The specific operation method is as follows: During the aeration process, the blower 21 ventilates the interior of the air cavity 23 through the air inlet pipe 24, and the gas drives the arc-shaped blade 42 to rotate, thereby rotating the mounting rod 41, driving the entire collecting mechanism 3 to work. At the same time, the gas enters the interior of the annular tube 25 from the ventilation 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, realizing the function of the linkage mechanism 4. At the same time, the suspended matter inside the wastewater pool 1 is salvaged by the collection mechanism 3. The salvage part 31 includes two device rods 311, on which a transmission wheel 312 and a transmission belt 313 are arranged. A salvage plate 314 is fixed on the outer peripheral side of the transmission belt 313, which is responsible for directly contacting the water surface to salvage the suspended matter. The recovery part 32 includes a recovery plate 321, a recovery flow channel 322 is provided on the top side, and a bottom ball is connected to a rolling ball 323, which rolls inside the limiting slide groove 12 to ensure the stability and movement flexibility of the recovery plate 321; When the suspended matter is transported to the recovery part 32 by the conveyor belt 313, the design of the recovery channel 322 enables the suspended matter to slide down and be discharged smoothly, completing the recovery process. The scraper 3174 at the bottom of the connecting plate 3173 fits with the inner wall of the collecting tank 14, ensuring that the suspended matter can be smoothly transferred from the collecting tank 14 to the discharge channel 15 for discharge; In addition, the design of the spoiler 411 disrupts the airflow, increases the contact area and contact time between the bubbles and the wastewater, and improves the oxygen transfer efficiency and aeration uniformity. The water seepage holes 318 are arranged on the conveyor belt 313 and the salvage plate 314, which improves the water discharge efficiency and ensures that the moisture in the salvaged suspended matter can be effectively removed.

[0038] It should be noted that the specific model specifications of the online monitoring device and the blower 21 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. The principles of these components are clear to technical personnel in this field and do not need to be described in detail here.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
