Description

Technical Field

[0002] Wastewater treatment refers to the process of removing pollutants from wastewater through physical, chemical, or biological methods to ensure that it meets discharge standards or reusable water quality requirements. For wastewater treatment plants, biological methods have become the mainstream technology for efficient wastewater treatment and improved environmental performance, as they utilize microorganisms to degrade organic matter. However, biological methods require oxygenation in aeration tanks to promote microbial metabolism. Traditional aeration equipment is costly and energy-intensive, significantly increasing the overall cost of wastewater treatment.

[0003] Chinese invention patent CN118420012A discloses an aeration control system and method for urban sewage treatment. To address the issue of optimizing the aeration process, sensors and cameras are used to collaboratively collect oxygen content data and aeration images, deep learning technology is used to extract dynamic feature vectors, and classifiers are used to determine the need for adjusting the working parameters of the aeration equipment in real time. Through intelligent regulation, the operation of aeration equipment is optimized, which significantly improves treatment efficiency and reduces energy consumption, solving the problems of delayed response and energy waste in traditional aeration modes. Chinese invention patent CN118239628A discloses a sewage treatment operation control system that constructs a multi-module collaborative control system, including modules such as nitrification reaction control, internal / external reflux control, intelligent dosing, COD control, precise aeration and carbon source addition.

[0004] While existing technologies have made progress in energy conservation and automated control of aeration equipment, the following technical bottlenecks remain: While microporous aeration can improve oxygen transfer efficiency, long-term operation can easily lead to contaminant adhesion leading to aeration tube blockage, which in turn can increase aeration resistance, reduce sealing performance, and damage the blower, ultimately reducing oxygen transfer efficiency and increasing maintenance costs.

[0020] The following describes three implementation methods of the present application in detail with reference to the accompanying drawings.

[0021] The first implementation method: Figure 1 - Figure 10The sewage treatment coordinated control system is shown, comprising an aeration tank 1, an aeration pipe group installed at the bottom of the aeration tank 1, an aeration pump coordinated with the aeration pipe group and arranged on the bank of the aeration tank 1, and a control box arranged on the rear side of the aeration pump.

A backflow sensing component 4 is installed at the upper end of the backflow sensing component 4, a check valve 31 is installed at the upper end of the check valve 31, and a microporous aeration disk 3 is installed at the upper end of the check valve 31. The microporous aeration disk 3 is connected to the aeration branch pipe 23 through the check valve 31 and the backflow sensing component 4. The aeration pipe group also includes a bottom annular pipe 21 fixedly installed at the bottom of the aeration tank 1, and a plurality of bottom branch pipes 22 are evenly distributed in the bottom annular pipe 21 and are sealed and connected with the bottom annular pipe 21. The upper end of the bottom annular pipe 21 is fixedly connected to the aeration pump pipe 2 in a sealed connection therewith. The upper end of the aeration pump pipe 2 extends to the outside of the aeration tank 1 and cooperates with the aeration pump. The aeration pipe group is arranged as an integral part in an inclined manner at the bottom of the aeration tank 1. When the aeration pump pipe 2 is arranged at the rear side of the annular pipe 21 at the bottom of the tank, the overall aeration pipe group is arranged at the bottom of the aeration tank 1 with the front lower and the rear higher. The lower end of the front side of the aeration pump pipe 2 is fixedly connected to a drainage pipe connected thereto, and an electric control valve is provided on the drainage pipe. When a backflow abnormality occurs in the microporous aeration disk 3, while being able to reversely flush the sewage therein, the sewage entering the aeration pipe group can also be discharged by opening the drainage pipe on the electric control valve, thereby avoiding corrosion damage to the aeration pipe group caused by the retention of sewage in the pipe. The electric control valve and the drainage function can be controlled by technical personnel, or can be implemented by setting a drainage control unit in conjunction with a balancing treatment unit in the aeration pipe. Users can select according to actual needs, and in the normal application stage, the electric control valve remains in a constant closed state to ensure the sealing of the aeration pipe group. The control box is equipped with an aeration tube balancing processing unit, the input end of the aeration tube balancing processing unit is connected to the aeration balance state acquisition unit, the output end of the aeration tube balancing processing unit is connected to the aeration coordinated control unit, the input end of the aeration balance state acquisition unit is connected to the backflow sensing component 4 signal, and the output end of the aeration coordinated control unit is connected to the aeration pump signal. Through the cooperation of the aeration balance state acquisition unit, the aeration tube balancing processing unit, the aeration coordinated control unit and the backflow sensing component 4, the intelligent coordinated control of the aeration pressure balance in the sewage treatment process can be effectively realized, and the microporous aeration disk 3 and the aeration tube can be controlled. The internal pressure state of the group is monitored in real time. According to the analysis of dual data during aeration operation and static state, the backflow abnormality data and sealing abnormality data are effectively obtained, and the abnormality is responded and fed back in time to avoid damage and blockage of the microporous aeration disk 3, thereby ensuring the safety and effectiveness of the aeration tube group application and reducing the difficulty of maintenance and inspection, thereby effectively forming a collaborative control system for real-time monitoring and dynamic regulation of the aeration tube group and the microporous aeration disk 3. While ensuring the oxygen transfer efficiency and reducing energy loss in the sewage treatment process, it can also effectively reduce the damage to each aeration structure, reduce the difficulty and cost of operation and maintenance, and promote the economic benefits of sewage treatment.

[0022] Figure 1 and Figure 3 It is shown that the input end of the balancing treatment unit in the aeration tube is also connected to the sewage treatment parameter acquisition unit, and the output end of the balancing treatment unit in the aeration tube is also connected to the in-tube balancing transmission unit. The input end of the sewage treatment parameter acquisition unit is connected to the data port signal set on the control box, and the output end of the in-tube balancing transmission unit is connected to the data port signal set on the control box. The data port can be connected to the sewage control management platform and the PC end signal, thereby realizing the input of parameters and the output of data feedback by the balancing treatment unit in the aeration tube. Through the cooperation of the sewage treatment parameter acquisition unit and the in-tube balancing transmission unit, the reception of treatment data and the transmission and feedback of monitoring data can be realized, effectively realizing the synergy of sewage treatment collaborative control and technical personnel, ensuring human participation, promoting the controllability of the sewage treatment process and the modifiable function of parameters, thereby ensuring the accuracy and effectiveness of the subsequent collaborative control data.

[0023] Figure 4 - Figure 10 The backflow sensing assembly 4 is shown to include a lower connector 42 fixedly installed in the aeration branch pipe 23, an upper end of the lower connector 42 is fixedly connected to a balance sensing sleeve 41, and an upper end of the balance sensing sleeve 41 is fixedly connected to an upper connector 43; A guide inner tube 5 disposed inside the balance sensing sleeve 41 is fixedly connected between the lower connector 42 and the upper connector 43. A plurality of embedded branch tubes 47 connected thereto are fixedly connected to the inner wall of the balance sensing sleeve 41, and the inner ends of the embedded branch tubes 47 extend to the inner side of the guide inner tube 5. An imbalance sensing chamber is provided in the balance sensing sleeve 41, and the upper and lower inner walls of the imbalance sensing chamber are connected to the backflow touch rod 6. The input end of the aeration balance state acquisition unit is connected to the backflow touch rod 6 signal. Through the cooperation of the backflow sensing component 4, the guide embedded tube 5, the backflow touch rod 6 and the aeration balance state acquisition unit, the internal pressure data of the aeration tube group and the sewage pressure can be balanced, and the dual data sensing of the aeration state during operation and the pressure state at rest can be realized. In this way, the sealing data of the aeration tube group and the backflow data of the microporous aeration disk 3 can be effectively judged and obtained, which can effectively reduce the difficulty of monitoring the status of the aeration tube group, promote the timeliness and effectiveness of maintenance, and can also effectively realize the dynamic regulation of the aeration pressure balance through subsequent regulation. In this way, while promoting the aeration effect and reducing the aeration energy consumption, it can effectively avoid damage to each aeration structure and promote its durability.

[0024] Figure 7 - Figure 9 The upper end of the upper connector 43 is connected to the check valve 31 , and the check valve 31 is connected to the aeration branch pipe 23 through the upper connector 43 , the guide embedded pipe 5 and the lower connector 42 ; The inner diameter of the guide embedded tube 5 is 5 to 8 times the inner diameter of the embedded branch tube 47. The stiffness coefficient of the balance sensing sleeve 41 is smaller than the stiffness coefficient of the guide embedded tube 5, and the guide embedded tube 5 produces a deformation effect along its axial direction. While ensuring the normal circulation of the airflow, the guide embedded tube 5 can also generate deformation feedback, and through the cooperation of the embedded branch tube 47 and the backflow sensing component 4, accurate sensing and triggering of deformation data are achieved, so as to promote the sensitivity and accuracy of pressure balance data monitoring.

[0025] Figure 6 - Figure 10It is shown that the upper end of the lower connecting head 42 is fixedly connected to a plurality of guide limit rods 44 arranged on the outside of the balance sensing sleeve 41, and the upper end of the guide limit rod 44 extends to the outside of the upper connecting head 43 and is in sliding cooperation with the upper connecting head 43. The lower connecting head 42 and the upper connecting head 43 are fixedly connected to a guide sleeve 46 that is slidably sleeved on the outside of the guide limit rod 44 at one end, and a protective elastic sleeve 45 that is slidably sleeved on the outside of the guide limit rod 44 is fixedly connected between the upper and lower guide sleeves 46. The cooperation of the guide limit rod 44, the protective elastic sleeve 45 and the guide sleeve 46 can further guide and position limit the deformation of the balance sensing sleeve 41 and the diversion embedded tube 5 through the upper connecting head 43, thereby ensuring the accuracy and effectiveness of data triggering, and can also effectively reduce the damage to the corresponding structure during deformation, promote the durability of the backflow sensing component 4 and the diversion embedded tube 5, and ensure the effectiveness of the aeration effect.

[0026] Figure 6 - Figure 10 It is shown that the inner diameter of the protective elastic sleeve 45 is 1.5 to 3 times the outer diameter of the guide limit rod 44. A pressure sensing probe is fixedly installed on the inner wall of the protective elastic sleeve 45. The input end of the aeration balance state acquisition unit is also connected to the pressure sensing probe signal. The cooperation between the pressure sensing probe and the aeration balance state acquisition unit can increase the data reference for pressure balance judgment, promote the reliability of subsequent control data, promote the accuracy of pressure balance compensation control and subsequent abnormal response, fully ensure the aeration effect, reduce damage to each aeration structure, and achieve effective coordinated control.

[0027] Figure 7 - Figure 9 It is shown that the upper and lower inner walls of the imbalance sensing chamber are fixedly connected with support auxiliary electromagnetic rings 7, and the backflow touch rod 6 is fixedly arranged on the side close to each other of the two support auxiliary electromagnetic rings 7. The output end of the balance processing unit in the aeration pipe is also connected to the balance monitoring and compensation unit. The output end of the balance monitoring and compensation unit is connected to the support auxiliary electromagnetic ring 7 signal. The cooperation between the balance monitoring and compensation unit and the support auxiliary electromagnetic ring 7 can compensate and regulate the deformation state of the backflow sensing component 4, thereby realizing the adaptability regulation of the distance between the two backflow touch rods 6. It can regulate the accuracy of abnormal triggering according to different aeration requirements, and promote the applicability of the sewage collaborative control system.

[0028] Figure 1 - Figure 10 The check valve 31 is shown to be a spring mechanical check valve, which is in a conductive state in which the aeration branch pipe 23 flows toward the microporous aeration disk 3, and the microporous aeration disk 3 is in a blocked state in the direction of the aeration branch pipe 23. The check valve 31 can effectively protect the aeration pipe group and prevent sewage backflow in a static state, which may cause damage to the aeration pipe group and the aeration pump.

[0029] Figure 1 - Figure 10 It shows that when the sewage treatment coordinated control system is applied, the technician transmits the sewage treatment parameter data in the aeration tank 1 to the sewage treatment parameter acquisition unit through the data port of the control box. The parameter data includes but is not limited to the sewage properties, aeration cycle, aeration volume, aeration pressure, aeration tube group laying data and aeration pump working parameter range and other related data. The data transmitted by the sewage treatment data acquisition unit of the balancing treatment unit in the aeration tube is analyzed, processed and applied; The balancing processing unit in the aeration pipe selects whether to regulate the triggering distance of the backflow touch rod 6 in the balancing induction sleeve 41 according to the set parameters. When higher triggering accuracy is required, the balancing monitoring compensation unit is regulated to pass current into the supporting auxiliary electromagnetic ring 7, causing the upper and lower supporting auxiliary electromagnetic rings 7 to produce a certain magnetic attraction effect, thereby reducing the triggering distance between the upper and lower side backflow touch rods 6, and being able to resist the elastic elongation of the balancing induction sleeve 41 and the guide embedded tube 5 and the airflow pressure in the pipe to a certain extent, so that the balancing induction sleeve 41 and the guide embedded tube 5 can timely deform and display the abnormality of sealing leakage or sewage backflow, thereby promoting the triggering of the backflow touch rod 6. Precision, to achieve high-precision monitoring and control requirements; when lower triggering precision is required, by regulating the balance monitoring compensation unit, it causes current to flow into the supporting auxiliary electromagnetic ring 7, causing the upper and lower supporting auxiliary electromagnetic rings 7 to produce a certain magnetic repulsion effect, increasing the triggering distance between the upper and lower side reverse flow touch rods 6, and being able to compensate for the elastic elongation of the balance sensing sleeve 41 and the guide embedded tube 5 and the airflow pressure in the tube to a certain extent, increasing the resistance of the balance sensing sleeve 41 and the guide embedded tube 5 to the reverse pressure of sewage, thereby slowing down their deformation image, reducing triggering precision, and avoiding false triggering and false alarms due to sewage fluctuations. It is effectively suitable for treating conditions with large sewage fluctuations; In addition, technical personnel can send sewage parameter data to the in-pipe balancing treatment unit in real time through the application of data ports and sewage treatment parameter collection units, so that the in-pipe balancing treatment unit can dynamically adjust the balance monitoring and compensation unit according to the actual fluctuation data of the sewage, so that it can effectively coordinate with the actual situation of the sewage and adjust the accuracy of the monitoring trigger appropriately. It can not only effectively ensure the effectiveness of monitoring and regulation, but also reduce false alarms and false triggers. While increasing the automation and intelligence level of the sewage treatment process, it can also effectively promote the efficiency and effectiveness of sewage treatment and ensure the economy of sewage treatment.

[0030] In the aeration state, the balance treatment unit in the aeration pipe controls the operation of the aeration pump through the aeration coordinated control unit, so that the airflow is input into the annular pipe 21 and the bottom branch pipe 22 of the pool through the aeration pump pipe 2. The airflow passes through the aeration branch pipe 23 and the guide embedded pipe 5 to open the check valve 31, and is discharged from the microporous aeration disk 3 to form microporous aeration, enter the aeration tank 1, mix with the sewage, and promote its treatment. When the airflow enters the guide embedded pipe 5 through the aeration branch pipe 23, part of the airflow will pass through the embedded branch pipe 47 enters the balance sensing sleeve 41, and stretches the balance sensing sleeve 41 and the guide embedded tube 5, causing the balance sensing sleeve 41 and the guide embedded tube 5 to drive the check valve 31 and the microporous aeration plate 3 to move upward for a certain distance through the upper connecting head 43, causing the upper connecting head 43 to move to the limit position of the guide limit rod 44 and stop. At this time, due to the upward movement of the upper connecting head 43, the protective elastic sleeve 45 will be released upward through the guide sleeve 46 connected thereto, causing the protective elastic sleeve 45 to produce a deformation. The balance sensing sleeve 41 is stretched and deformed, and the pressure in the space formed between the balance sensing sleeve 41 and the guide limit rod 44 is restored, and the pressure sensing probe synchronizes the sensed pressure data to the aeration balance state acquisition unit in real time. In addition, since the balance sensing sleeve 41 stretches and recovers the deformation, the upper and lower side backflow touch rods 6 located in the balance sensing sleeve 41 do not generate conflict triggering data. The aeration balance state acquisition unit can receive the disconnection signal, and then convert the pressure data and the disconnection data, and transmit the status data to the balance processing unit in the aeration pipe. The balance processing unit in the aeration pipe obtains the state of the microporous aeration at this time according to the status data. When it is judged that the balance sensing sleeve 41 and the guide embedded pipe 5 have not completely stretched and recovered the deformation according to the pressure data, the aeration coordinated control unit is used to compensate and control the aeration pump to increase its efficacy and increase the pressure of the airflow in the pipe, effectively promoting the aeration amount according to the actual application situation, achieving the oxygen increase target and effectively reaching the set value, reducing the aeration error, and ensuring the efficiency of sewage treatment. After aeration has continued for a period of time and the set cycle duration has been reached, the balancing treatment unit in the aeration pipe will control the aeration pump to stop through the aeration coordinated control unit to avoid damage caused by the continuous operation of the aeration pump. While ensuring that the aeration volume can effectively act on sewage treatment, it will reduce aeration energy consumption and promote the environmental friendliness of the sewage treatment process. In addition, during the aeration treatment process, the balancing treatment unit in the aeration pipe can display the data it controls and monitors to the technical staff through the data port in real time through the balancing transmission unit in the pipe, so that the technical staff can obtain the aeration status and sewage treatment efficiency. When the parameters need to be adjusted, manual intervention can be carried out in time to avoid errors in automatic operation and promote the reliability of sewage treatment.

[0031] In the static state, the balancing treatment unit in the aeration pipe controls the aeration pump to stop running through the aeration coordinated control unit. At this time, the pressure in the aeration pump pipe 2, the pool bottom annular pipe 21 and the pool bottom branch pipe 22 is kept in a static state, and due to the internal pressure, the balancing induction sleeve 41 and the diversion embedded pipe 5 can be deformed to maintain support, and when there is sewage fluctuation, the electromagnetic repulsion of the supporting auxiliary electromagnetic ring 7 can be cooperated to further maintain the supporting role of the balancing induction sleeve 41 and the diversion embedded pipe 5. At this time, under the reverse pressure generated by the sewage on the microporous aeration disk 3, the balancing induction sleeve 41 and the diversion embedded pipe 5 are The embedded tube 5 in the flow will produce a certain contraction deformation. At this time, the pressure in the protective elastic sleeve 45 will produce an increasing data change. Then, after the change is completed, a basically constant pressure value is generated. At the same time, the backflow touch rods 6 on the upper and lower sides are still in the disconnected state. The aeration balance state acquisition unit can collect the pressure data and continuous disconnection data at this time and transmit them to the balance processing unit in the aeration pipe. The balance processing unit in the aeration pipe determines the status of the aeration pipe group and the microporous aeration disk 3 based on the acquired data. At this time, they are in a good and stable state. Then, the data is displayed to the technicians through the balance transmission unit in the pipe and the data port. When a poor seal occurs at the pipe connection of the aeration pipe group, the pressure in the aeration pipe group will leak in a static state, and then continue to decrease. The reduced pressure in the pipe cannot effectively resist the reverse pressure of the sewage outside the microporous aeration plate 3, which will cause the upper connector 43 to compress the balancing sensor sleeve 41 and the guide embedded pipe 5 under the action of the external sewage reverse pressure; or when the microporous aeration plate 3 generates sewage backflow, causing the sewage to flow through the microporous aeration plate 3 to the check valve 31, the external reverse pressure of the sewage on the microporous aeration plate 3 combined with the pressure on the check valve 31 after entering the microporous aeration plate 3, will cause the upper connector 43 to compress the balancing sensor sleeve 41 and the guide embedded pipe 5. Then, the guide sleeve 46 on the upper connector 43 squeezes the protective elastic sleeve 45. The compression of the protective elastic sleeve 45 enables the pressure sensing probe to monitor a larger pressure data. The aeration balance state acquisition unit can receive the pressure data. Under the action of the continuous contraction and deformation of the balance sensing sleeve 41, the backflow touch rods 6 on the upper and lower sides will be triggered. While resisting the contraction and deformation of the balance sensing sleeve 41 and the guide embedded tube 5, it can also transmit a trigger signal to the aeration balance state acquisition unit. The aeration balance state acquisition unit transmits the pressure data and the trigger data to the balance processing unit in the aeration pipe. The balance processing unit in the aeration pipe determines that the monitoring data is abnormal at this time and needs to judge and troubleshoot the cause of the abnormality. At the same time, the abnormal data is displayed to the technicians through the balance transmission unit in the pipe and the data port, so that the technicians can check the abnormality in time. After determining that there is abnormal data, the balancing processing unit in the aeration pipe controls the aeration pump through the aeration coordinated control unit to generate a single aeration operation. The single aeration operation will input instantaneous boost data into the aeration pipe group, and the air flow will push the check valve 31 through the aeration branch pipe 23 and the guide embedded pipe 5 to be discharged from the microporous aeration disk 3, generating a single microporous aeration effect or aerating and flushing the sewage in the microporous aeration disk 3. At the same time, the single aeration effect will also act on the balancing sensing sleeve 41 through the embedded branch pipe 47, causing the balancing sensing sleeve 41 and the guide embedded pipe 5 to produce accompanying deformation. The pressure sensing probe and the backflow feeler rod 6 generate corresponding data changes and transmit them to the balance monitoring and compensation unit. At this time, the balancing processing unit in the aeration pipe determines the cause of the abnormality based on the monitoring data. When the pressure data decreases but does not reach the pressure data of the aeration state, and the difference is large, it is determined that the aeration tube group has a poor seal. The balance processing unit in the aeration tube will feed back the cause judgment result to the technician through the balance transmission unit in the tube and the data port, so that the technician can respond to the abnormality and perform maintenance on the aeration tube group to avoid problems such as poor aeration caused by continuous damage to the seal and damage to the aeration pump, thereby ensuring the effectiveness of aeration operation and the effectiveness of sewage treatment; When it is judged that the pressure data is basically the same as the pressure data in the aeration state and the difference is not large, it is judged that sewage backflow occurs in the microporous aeration disk 3. While the aeration coordinated control unit is used to perform a single control on the aeration pump to backflush the sewage in the microporous aeration disk 3, the balancing processing unit in the aeration pipe can also feed back the cause judgment result to the technician through the in-pipe balancing transmission unit and the data port, so that the technician can respond to the abnormality and maintain the microporous aeration disk 3 in time. The technician controls the electric control valve on the drain pipe, or the balancing processing unit in the aeration pipe controls the electric control valve through the discharge control unit, and the sewage that may enter the aeration pipe group when the cause is judged is discharged through the drainage pipe, thereby avoiding the retention of sewage in the pipe and ensuring the durability of the aeration pipe group.

[0032] Furthermore, by dual monitoring of the aeration state and the static state, and generating appropriate dynamic control compensation, it is possible to effectively realize real-time monitoring of the status of the microporous aeration disk 3 and the aeration tube group and dynamic control of the application effectiveness, avoid damage and blockage of the microporous aeration disk 3, ensure the safety and effectiveness of the application of the aeration tube group, reduce the difficulty of maintenance and inspection, and effectively form a collaborative control system for real-time monitoring and dynamic control of the aeration tube group and the microporous aeration disk 3. While ensuring the oxygen transfer efficiency and reducing energy loss in the sewage treatment process, it can also effectively reduce damage to each aeration structure, reduce the difficulty and cost of operation and maintenance, and promote the economic benefits of sewage treatment.

[0033] Second implementation method: Figure 1 - Figure 10 The sewage treatment coordinated control system is shown. As a replacement for the spring mechanical check valve in the first embodiment, the check valve 31 is a pneumatic check valve. A matching cylinder structure is installed on the right side of the pneumatic check valve. The lower end of the cylinder structure is sealed and connected to an air pressure pipe. The other end of the air pressure pipe is connected to the pneumatic controller through a pipeline diverter. The output end of the balancing processing unit in the aeration pipe is also connected to a one-way top-opening air pressure control unit. The output end of the one-way top-opening air pressure control unit is connected to the pneumatic controller signal, and can regulate the one-way top-opening pressure of the pneumatic check valve. The setting of the one-way top-opening air pressure control unit can realize the intelligent regulation of the top-opening pressure of the microporous aeration disk 3. When the aeration is in operation, it can quickly regulate and reduce its ventilation resistance, reduce energy loss during aeration and mechanical damage to the aeration pump, and restore the top-opening pressure of the microporous aeration disk 3 when it is stationary, so as to avoid sewage backflow, ensure the effectiveness of subsequent data monitoring of the backflow sensing component 4 and the backflow touch rod 6, further ensure the safety of the operation of each aeration structure during sewage treatment, reduce operational damage, and promote durability.

[0034] Figure 1 - Figure 10 It is shown that when the check valve 31 is a pneumatic check valve, its opening pressure can be changed by regulating the pressure in the cylinder structure, and then in the aeration state, the balancing processing unit in the aeration pipe regulates the pneumatic controller through the one-way opening pressure regulating unit, so that the air pressure in the cylinder structure is regulated, and the opening pressure of the pneumatic check valve is reduced, thereby promoting the efficiency of the airflow to open the check valve 31, promoting the working efficiency of the aeration pump, reducing the kinetic energy loss of the airflow, and thereby promoting the microporous aeration effect of the microporous aeration plate 3, and in the static state, in the aeration state, the balancing processing unit in the aeration pipe regulates the pneumatic controller through the one-way opening pressure regulating unit, so that the air pressure in the cylinder structure is regulated, and the opening pressure of the pneumatic check valve is increased, thereby ensuring its sealing effect, avoiding the subsequent backflow of the microporous aeration plate 3 causing sewage to enter the aeration pipe group, causing corrosion damage to the aeration pipe group, and fully ensuring the safety of the continuous use of the aeration pipe group. It can then effectively play a dynamic regulatory role in applicability, effectively coordinate and regulate different sewage treatment states, and while promoting sewage treatment efficiency, ensure the safety of each aeration structure and increase its durability.

[0035] The third implementation method: Figure 1 - Figure 10 A sewage treatment method is shown, which is based on the sewage treatment coordinated control system in the above embodiment and includes the following steps: S1. Aeration treatment, According to the sewage status and sewage treatment parameters in the aeration tank 1, the aeration coordinated control unit controls the operation of the aeration pump so that it aerates the aeration tank 1 through the aeration pipe group, generates microporous aeration, and increases the oxygen content in the aeration tank 1; When the aeration coordinated control unit controls the aeration pump to operate, the airflow entering the aeration pipe group can pass through the top-open check valve 31, and the airflow passes through the microporous aeration disk 3 to produce microporous aeration; S2. Monitoring and control of aeration pressure, The aeration balance state acquisition unit and the backflow sensing component 4 can collect real-time data on the pressure state of the aeration effect at this time. After the balance processing unit in the aeration pipe processes and judges the collected data, the aeration coordinated control unit controls and compensates the aeration pump; S3. Aeration and static, According to the sewage status and sewage treatment parameters in the aeration tank 1, the aeration coordinated control unit controls the aeration pump to stop and generate an aeration static effect; When the aeration is static, the air flow in the aeration pipe group stops flowing, and the check valve 31 is closed, preventing the sewage from flowing back through the microporous aeration disk 3; S4. Monitoring and control of static pressure, The aeration balance state acquisition unit and the backflow sensing component 4 can collect real-time data on the pressure state of the static effect at this time. After the balance processing unit in the aeration pipe processes and judges the collected data, it can generate data feedback on the judgment result in a timely manner. S5. Reflux regulation, When the balance treatment unit in the aeration pipe determines that a backflow anomaly occurs, the aeration coordinated control unit performs a single control on the aeration pump, so that it blows air to the check valve 31 and the microporous aeration disk 3 through the aeration pipe group to discharge the backflow sewage. By collecting and judging the pressure balance data of the aeration operation state and the static state during the sewage treatment process, the state of the aeration pipe group and the microporous aeration disk 3 can be effectively obtained, and then the subsequent coordinated control of the aeration pressure and the dynamic control of the pressure balance can be realized. In this way, while promoting the aeration effect, increasing the oxygen concentration in the aeration tank 1, and promoting the sewage treatment efficiency, the sealing and blockage data can also be collected, fed back, and regulated and suppressed, reducing the damage of each aeration structure, effectively reducing the difficulty of operation and maintenance monitoring of the aeration pipe group and the microporous aeration disk 3, reducing its operation damage, promoting durability, and promoting the economy of sewage treatment.

Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
