Description

Technical Field

[0001] The present application relates to the field of water treatment control technology, and in particular to a method and system for controlling water treatment pulse vibration. Background Art

[0002] Traditional sewage treatment methods, such as the activated sludge method and the biological filter method, although they can purify sewage to a certain extent, still have many problems, such as low treatment efficiency, high energy consumption, and poor adaptability to complex working conditions. In order to improve sewage treatment efficiency, reduce energy consumption, and enhance the ability to treat different sewage characteristics, some new technologies and methods have emerged in recent years. Among them, pulse vibration technology, as an emerging means, has been gradually applied to the field of sewage treatment. By introducing intermittent vibrations in the sewage pool, this technology can improve the degradability of pollutants in sewage, increase the activity of the biological treatment process, and thus enhance the treatment efficiency of sewage.

[0003] At present, the existing pulse vibration control method for sewage treatment sets fixed pulse vibration parameters based on historical sewage treatment experience, and performs pulse vibration treatment on the sewage in the sewage pool. However, in actual applications, since there are multiple sewage treatment stages in the entire sewage treatment process, the water quality of sewage in different treatment stages is different. The use of fixed pulse vibration parameters often ignores the dynamic changes of sewage in different sewage pools during the treatment process, and it is difficult to coordinate the pulse vibration work of sewage pools at different treatment stages, resulting in low efficiency in sewage treatment through pulse vibration. Summary of the invention

[0004] The present application provides a control method and system for water treatment pulse vibration, which can coordinate the pulse vibration work of sewage pools in different treatment stages by adjusting the pulse vibration frequency, thereby improving the sewage treatment efficiency of pulse vibration.

[0005] In a first aspect, the present application provides a pulse vibration regulation method for sewage treatment, comprising:

[0006] Obtaining pulse response time of multiple sewage pools when pulse vibration is applied, and water quality parameters after pulse vibration, each of the sewage pools being in a different stage;

[0007] Based on the water quality parameters and pulse response time of each of the sewage pools, determining at least one target sewage pool having a pulse response offset less than an offset threshold;

[0008] The pulse vibration frequency of each target sewage pool is adjusted according to the water quality parameters of each target sewage pool.

[0009] By adopting the above technical solution, the response time and water quality parameters of sewage pools at different stages can be obtained, so as to fully understand the treatment status and response characteristics of each sewage pool. Among these sewage pools, the target sewage pool with smaller response time deviation and more conducive to coordinated control is determined. Then, based on the water quality parameters of the target sewage pool, the vibration frequency is adjusted for each sewage pool to achieve parameter adjustment. In this way, target extraction and intelligent control are performed on the basis of multi-parameter detection, so that the treatment system can achieve closed-loop control of water quality adaptation. By setting the pulse vibration frequency according to the water quality status and the pulse vibration response time, it is beneficial for each sewage pool to maintain coordinated pulse vibration, and the dynamic optimization of parameters in the coordinated control of multiple sewage pools is realized, so that the treatment system can perform targeted control according to the specific situation of each sewage pool, coordinate the pulse vibration of sewage pools at each stage, and improve the efficiency of pulse vibration in sewage treatment.

[0010] Optionally, the target pulse vibration frequency of each target sewage pool is determined according to the pollutant purification amount, sewage temperature variable and sewage pH value variable of each target sewage pool; and the pulse vibration frequency of each target sewage pool is adjusted based on the target pulse vibration frequency of each target sewage pool.

[0011] By adopting the above technical solution, after determining the target sewage pool, the target vibration frequency of each target sewage pool is further calculated and set according to multiple parameters such as the pollutant purification amount, temperature change and pH change. Then, based on these target frequencies, the actual pulse vibration frequency of each sewage pool is accurately adjusted. In this way, the target frequency is obtained through multi-parameter calculation, and then closed-loop control adjustment is performed, which can make the frequency setting and control more accurate.

[0012] Optionally, the pollutant purification amount, sewage temperature variable and sewage pH value variable of each target sewage pool are substituted into a preset formula to calculate the target pulse vibration frequency of each target sewage pool;

[0013] Wherein, the preset formula is:

[0014] ;

[0015] In the formula, represents the target pulse vibration frequency of the i-th target sewage pool, represents the proportionality constant of the target pulse vibration frequency, The polynomial coefficients representing the amount of pollutant purification in the i-th target sewage pool, represents the pollutant purification amount of the i-th target sewage pool, Indicates the maximum pollutant purification capacity, Indicates the minimum pollutant purification amount, represents the polynomial coefficient of the sewage temperature variable in the i-th target sewage pool, represents the sewage temperature variable of the i-th target sewage pool, represents the maximum sewage temperature variable, represents the minimum sewage temperature variable, represents the polynomial coefficient of the pH value variable of the sewage in the i-th target sewage pool, represents the pH value variable of the sewage in the i-th target sewage pool, represents the maximum sewage pH value variable, represents the minimum sewage pH value variable, represents the proportion of sewage pools in the synchronous pulse mode in the pulse vibration, represents the proportion of sewage pools in asynchronous pulse mode in the pulse vibration, represents the pulse time offset of the i-th target sewage pool, represents the upper limit of the polynomial degree of the pollutant purification amount, represents the upper limit value of the polynomial degree of the sewage temperature variable, represents the upper limit of the polynomial degree of the sewage pH value variable, The polynomial upper limit value representing the pulse time offset.

[0016] By adopting the above technical solution, when calculating the target frequency, various water quality parameters are substituted into the preset formula for calculation to obtain the target vibration frequency of each target sewage pool. The target frequency is calculated by the preset formula to achieve quantitative determination of the target frequency. The preset formula comprehensively considers the influence of multiple water quality parameters, and the errors of subjective decision-making can be eliminated through quantitative calculation. Using the preset formula to calculate the target frequency can make the frequency setting more accurate.

[0017] Optionally, obtain the first pollutant concentration, first sewage temperature, first sewage pH value and initial pulse vibration parameters of each sewage pool before pulse vibration; perform the pulse vibration on each sewage pool based on the initial pulse vibration frequency, initial pulse vibration amplitude and pulse interval time of each sewage pool to obtain the second pollutant concentration, second sewage temperature and second sewage pH value of each sewage pool; determine the pollutant purification amount according to the first pollutant concentration and the second pollutant concentration of each sewage pool, determine the sewage temperature variable according to the first sewage temperature and the second sewage temperature of each sewage pool, and determine the sewage pH value variable according to the first sewage pH value and the second sewage pH value of each sewage pool; use the pollutant purification amount, sewage temperature variable and sewage pH value variable of each sewage pool as the water quality parameters.

[0018] By adopting the above technical scheme, the pollutant concentration, temperature and pH value of the sewage pool before and after vibration are obtained, and the purification amount, temperature variable and pH variable are determined as water quality parameters according to the difference between the two tests. This can directly reflect the actual purification effect and water quality changes of the sewage under the action of pulse vibration. The water quality parameters are obtained through comparative tests and optimized control. In this way, closed-loop feedback and adaptive adjustment between the water quality state and the control parameters can be formed. The parameter configuration can be updated and iterated as the sewage treatment effect changes, thereby realizing precise control of the sewage treatment process.

[0019] Optionally, a synchronized pulse sewage pool group is determined based on the pulse response time of each sewage pool; the sewage treatment efficiency of each sewage pool in the synchronized pulse sewage pool group within a preset period is determined based on the pollutant purification amount, sewage temperature variable and sewage pH value variable of each sewage pool in the synchronized pulse sewage pool group; and all sewage pools in the synchronized pulse sewage pool group whose sewage treatment efficiency is greater than the preset sewage treatment efficiency are taken as the target sewage pools.

[0020] By adopting the above technical solution, a synchronous pulse sewage pool group is formed based on the response time, and then the sewage pool with a treatment efficiency higher than the preset value calculated according to the water quality parameters is screened out from the group and determined as the target sewage pool. This multi-stage screening can make the selection of the target sewage pool more accurate and effective. The sewage pools in the synchronous group have synergistic conditions, and extracting the sewage pool with high efficiency from them can improve the overall treatment efficiency.

[0021] Optionally, the pulse start time and pulse end time of each sewage pool are determined according to the pulse response time of each sewage pool; each pulse start time and each pulse end time are compared with a preset standard pulse time period to obtain the pulse time offset of each sewage pool; all sewage pools whose pulse time offset is less than the preset pulse time offset are taken as the synchronous pulse sewage pool group.

[0022] By adopting the above technical solution, the response time is analyzed to determine the pulse start and end time of each sewage pool, and the time offset between it and the standard time period is calculated. The offset is used to determine whether it is included in the synchronization group. This technical means based on response time analysis and offset calculation can achieve accurate quantitative judgment of the sewage pool pulse timing. The offset is a quantitative standard for judging synchronization. By setting the offset threshold, the synchronous sewage pool can be effectively extracted. The response time analysis and offset calculation are used to determine the synchronization group. This can avoid the errors caused by subjective division, making the judgment of the synchronous sewage pool more scientific and objective, thereby improving the coordination of subsequent control.

[0023] Optionally, among the pulse response times of each of the target sewage pools, a minimum pulse response time is determined; based on the pulse signal corresponding to the minimum pulse response time, a pulse vibration interval duration and a pulse vibration duration are determined; based on the pulse vibration interval duration and the pulse vibration duration, a target pulse vibration period is determined; and based on the target pulse vibration period, the pulse vibration period of each of the sewage pools is adjusted.

[0024] By adopting the above technical solution, the technical means of setting the global target cycle based on the minimum response time can ensure the rationality of the cycle parameters. The minimum response time represents the fastest responding sewage pool, and its waveform analysis cycle can make all sewage pools adapt. The signal with the minimum response time is used as the standard to set the cycle, and then adjust and control it. This can effectively avoid the synchronization of individual sewage pools due to insufficient response, and the unified configuration of the cycle can achieve coordinated control of the overall sewage pool.

[0028] The pulse vibration adjustment module is used to adjust the pulse vibration frequency of each of the target sewage pools according to the water quality parameters of each of the target sewage pools.

[0030] An electronic device comprises a memory, a processor and a program stored in the memory and executable on the processor. The program can realize a pulse vibration regulating method for sewage treatment when loaded and executed by the processor.

[0032] A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the processor implements a pulse vibration regulation method for sewage treatment.

[0034] By adopting the technical solution of the present application, the response time and water quality parameters of sewage pools at different stages are obtained, and the treatment status and response characteristics of each sewage pool can be fully understood. Among these sewage pools, a target sewage pool with a smaller response time deviation and more conducive to coordinated control is determined. Then, based on the water quality parameters of the target sewage pool, the vibration frequency is adjusted for each sewage pool to achieve parameter adjustment. In this way, target extraction and intelligent control are performed on the basis of multi-parameter detection, so that the treatment system can achieve closed-loop control of water quality adaptation. By setting the pulse vibration frequency according to the water quality status and the pulse vibration response time, it is beneficial for each sewage pool to maintain coordinated pulse vibration, and the dynamic optimization of parameters in the coordinated control of multiple sewage pools is realized, so that the treatment system can perform targeted control according to the specific situation of each sewage pool, coordinate the pulse vibration of sewage pools at each stage, and improve the efficiency of pulse vibration in sewage treatment.

[0042] The present application embodiment provides a pulse vibration control method for sewage treatment. In one embodiment, please refer to Figure 1 , Figure 1 This is a flow chart of the pulse vibration control method for sewage treatment provided by the embodiment of the present application. The method can be implemented by a computer program, which can be integrated in an application or run as an independent tool application. The method can also be implemented by a single-chip microcomputer or run on a pulse vibration control system for sewage treatment based on the von Neumann system. Specifically, the method can include the following steps:

[0043] Step 101: Obtain the pulse response time of multiple sewage pools during pulse vibration, as well as the water quality parameters after the pulse vibration, and each sewage pool is in a different stage.

[0044] Among them, pulse vibration refers to the process of applying vibration or vibration to the sewage pool in the form of pulses through the pulse vibration equipment in the sewage pool. In the embodiment of the present application, pulse vibration can be understood as intermittently applying mechanical vibration or vibration of a certain intensity to the sewage pool. The purpose of pulse vibration is to use the physical effect of vibration to improve the degradation performance of pollutants in sewage, enhance the biological reaction process of the sewage treatment system, and thus improve the efficiency of sewage treatment.

[0045] Water quality parameters refer to various indicators for evaluating water quality conditions. In the embodiments of the present application, water quality parameters can be understood as various parameters that need to be monitored and controlled during sewage treatment, mainly including pollutant concentration, temperature, pH value, etc.

[0046] Stage refers to the sewage treatment stage, which means a treatment unit in the entire treatment process from the sewage entering the treatment system to the final discharge. A sewage treatment system usually includes multiple treatment stages, and each stage treats the sewage with a specific treatment process.

[0047] The pulse response time refers to the time interval from the sewage pool receiving the pulse vibration signal to the time when the water quality parameters change significantly. In the embodiment of the present application, the pulse response time can be understood as the time it takes for the sewage pool in each sewage treatment stage to receive the pulse vibration and the pollutant concentration, temperature and other parameters to change significantly.

[0048] Specifically, according to the initial vibration frequency, amplitude and other parameters of each sewage pool, the pulse vibration device of the sewage pool is started to intermittently vibrate the sewage in the sewage pool. Using online detection instruments, water quality parameters such as the concentration of chemical oxygen demand producing substances, the concentration of biological oxygen demand producing substances, the concentration of suspended solids, temperature, pH value, etc. are continuously monitored during the vibration process. When the water quality parameters are significantly improved, the response time from the start of vibration to the change of water quality parameters is recorded. The purpose of the initial parameter pulse vibration is to test the impact of parameters on the sewage treatment effect at each stage, and to evaluate the differences in treatment responses between different sewage pools through response time. These data will provide a basis for the subsequent determination of the optimal parameters and the coordination of each sewage pool to achieve synchronous pulses.

[0049] Based on the above embodiment, as an optional embodiment, in step 101: obtaining the pulse response time of multiple sewage pools when pulse vibration is performed, and the water quality parameters after the pulse vibration, before this step, the following steps may also be included:

[0050] Step 201: Obtain the first pollutant concentration, the first sewage temperature, the first sewage pH value and the initial pulse vibration parameters of each sewage pool before pulse vibration.

[0051] The first pollutant concentration refers to the initial concentration level of pollutants contained in the sewage before the sewage pool is subjected to pulse vibration treatment. In the embodiment of the present application, the first pollutant concentration can be understood as the measured values ​​of pollution index parameters such as COD concentration, i.e., chemical oxygen demand producing substance concentration, BOD concentration, i.e., biological oxygen demand producing substance, in the sewage before pulse vibration.

[0052] The first sewage temperature refers to the initial temperature value of the sewage before the sewage pool is subjected to pulse vibration treatment. In the embodiment of the present application, the first sewage temperature can be understood as the temperature reading of the sewage in the sewage pool obtained by measuring with a thermometer before the pulse vibration.

[0053] The first sewage pH value refers to the initial pH value of the sewage before the sewage pool is subjected to pulse vibration treatment. In this embodiment of the present application, the first sewage pH value can be understood as the pH reading of the sewage in the sewage pool obtained by measuring with a pH meter before pulse vibration.

[0054] The initial pulse vibration parameters refer to a combination of a set of pulse vibration control parameters given based on experience or pre-setting before the sewage pool is pulsed and vibrated. In the embodiment of the present application, the initial pulse vibration parameters can be understood as the pulse vibration frequency, amplitude, interval time and other parameters pre-set according to the process conditions and historical data of each sewage treatment stage before the response test.

[0055] Specifically, by connecting the sewage quality online monitoring equipment, before applying vibration to the sewage pool, after judging that the monitoring equipment is operating normally, the sewage quality parameters are continuously monitored. The average or stable value of the pollutant concentration, temperature and pH over a period of time is recorded as the first pollutant concentration, the first sewage temperature and the first sewage pH value. These initial water quality parameters can also be obtained by manual sampling and testing. The purpose of measuring these initial water quality parameters is to determine the pre-treatment condition of the sewage and obtain a set of benchmark data.

[0056] Step 202: Based on the initial pulse vibration frequency, initial pulse vibration amplitude and pulse interval time of each sewage pool, pulse vibration is performed on each sewage pool to obtain the second pollutant concentration, second sewage temperature and second sewage pH value of each sewage pool.

[0057] Among them, the initial pulse vibration frequency refers to the frequency parameter of the pulse oscillation determined based on experience or preliminary testing before the sewage pool is subjected to pulse vibration treatment. In the embodiment of the present application, the initial pulse vibration frequency can be understood as the frequency level of pulse oscillation applied to the sewage pool, which is pre-set according to process conditions before the parameters of the specific sewage pool are optimized.

[0058] The initial pulse vibration amplitude refers to the intensity parameter of the pulse oscillation determined based on experience or pre-testing before the sewage pool is subjected to pulse vibration treatment. In the embodiment of the present application, the initial pulse vibration amplitude can be understood as the intensity level of the pulse oscillation applied to the sewage pool, which is pre-set according to the process conditions before the parameters of the specific sewage pool are optimized.

[0059] The pulse interval time refers to the time interval between two pulse vibrations when applying pulse vibration to the sewage pool. In the embodiment of the present application, the pulse interval time can be understood as the time interval between the end of one pulse vibration and the beginning of the next pulse vibration when the sewage pool is subjected to pulse vibration treatment.

[0060] Specifically, according to the initial vibration frequency, initial vibration amplitude and pulse interval time pre-set for each sewage pool, the control system sends a control signal to start the pulse vibration device, and applies intermittent vibration to the sewage pool according to the set time sequence. The online detection instrument monitors the COD concentration, BOD concentration and other pollutant concentrations, temperature, and pH values ​​in the sewage. When stable, they are recorded as the second pollutant concentration, the second sewage temperature and the second sewage pH value. The purpose of initial parameter vibration is to verify the treatment effect of these parameters on each sewage. By comparing the changes in sewage quality before and after vibration, the rationality of the initial parameters can be judged, providing a basis for subsequent parameter optimization.

[0061] Step 203: Determine the pollutant purification amount according to the first pollutant concentration and the second pollutant concentration of each sewage pool, determine the sewage temperature variable according to the first sewage temperature and the second sewage temperature of each sewage pool, and determine the sewage pH value variable according to the first sewage pH value and the second sewage pH value of each sewage pool; use the pollutant purification amount, sewage temperature variable and sewage pH value variable of each sewage pool as water quality parameters.

[0062] The second pollutant concentration refers to the pollutant concentration level of the sewage pool after the pulse vibration treatment. The second sewage temperature refers to the sewage temperature value of the sewage pool after the pulse vibration treatment. The second sewage pH value refers to the sewage pH value of the sewage pool after the pulse vibration treatment.

[0063] The pollutant purification amount refers to the reduction in pollutant concentration after the sewage is treated with pulse vibration. In the embodiment of the present application, the pollutant purification amount can be understood as the change in the concentration of pollution indicators such as COD and BOD in the sewage before and after pulse vibration.

[0064] The sewage temperature variable refers to the change in sewage temperature after the sewage is treated with pulse vibration. In the embodiment of the present application, the sewage temperature variable can be understood as the magnitude of the change in the temperature value of the sewage before and after the pulse vibration.

[0065] The pH value variable of sewage refers to the change in the pH value of sewage after the sewage is treated with pulse vibration. In the embodiment of the present application, the pH value variable of sewage can be understood as the magnitude of the change in the pH value of sewage before and after pulse vibration.

[0066] Specifically, the COD concentration of the sewage before and after the initial parameter vibration of each sewage pool is called, and the difference between the two is calculated as the pollutant purification amount; then the sewage temperature before and after the vibration is called, and the difference between the two is calculated as the sewage temperature variable; finally, the pH value is called, and the pH change is calculated as the sewage pH value variable, and the calculated pollutant purification amount, sewage temperature variable and sewage pH value variable are used as the water quality parameters of each sewage pool after pulse vibration. The purpose of the calculation is to obtain three quantitative indicators to judge the effect of the initial parameter pulse vibration. The size of these variables can compare the treatment effects of different sewage pools.

[0067] Step 102: Based on the water quality parameters and pulse response time of each sewage pool, determine at least one target sewage pool whose pulse response offset is less than an offset threshold.

[0068] The target sewage pool refers to a representative sewage pool selected from multiple sewage pools and suitable for parameter optimization test. In the embodiment of the present application, the target sewage pool can be understood as a sewage pool sample with better treatment effect and shorter response time to pulse vibration selected based on the comparison of water quality parameters and response time of each sewage pool.

[0069] Specifically, the second pollutant concentration, second sewage temperature, and second sewage pH value of each sewage pool after the initial parameter vibration are retrieved, and the pollutant purification amount, sewage temperature variable, and sewage pH value variable are calculated. Then the pulse response time of each sewage pool is retrieved. The system compares and analyzes the water quality parameters and response time of each sewage pool, and selects the sewage pool with good treatment effect and short response time as the target sewage pool. The purpose of determining the target sewage pool is to select a sewage pool sample with good representativeness and good control effect. Parameter optimization experiments can be efficiently carried out on this sample without the need to test all sewage pools one by one in detail, thereby shortening the experimental cycle and improving control efficiency.

[0070] Based on the above embodiment, as an optional embodiment, in step 102: based on the water quality parameters and pulse response time of each sewage pool, determining at least one target sewage pool whose pulse response offset is less than the offset threshold, this step may also include the following steps:

[0071] Step 301: Determine a synchronous pulse sewage pool group according to the pulse response time of each sewage pool.

[0072] Among them, the synchronous pulse sewage pool group refers to a group that groups sewage pools with similar response times according to the pulse response time of the sewage pool. In the embodiment of the present application, the synchronous pulse sewage pool group can be understood as a group of sewage pools with pulse response time differences within an acceptable range, as a sewage pool group that can use the same or similar control parameters.

[0073] Specifically, the pulse response time data of each sewage pool after the initial parameter vibration is retrieved. Then the response time of different sewage pools is compared and analyzed, and sewage pools with similar response times are selected to be divided into a synchronous pulse sewage pool group. The purpose of dividing the synchronous group is to make sewage pools with similar response times use the same vibration control frequency and rhythm, which can achieve collaborative optimization. If the same control strategy is used for sewage pools with large differences in response time, it will lead to uneven treatment effects. By grouping sewage pools according to response time, the sewage in each group can be in a synchronous pulse state, and the optimal control parameters can be formulated for each group, so that the overall treatment system can achieve optimal coordinated operation.

[0074] Based on the above embodiment, as an optional embodiment, in step 301: determining a synchronous pulse sewage pool group according to the pulse response time of each sewage pool, this step may also include the following steps:

[0075] Step 311: Determine the pulse start time and pulse end time of each sewage pool according to the pulse response time of each sewage pool.

[0076] Among them, the pulse start time refers to the starting time point for applying pulse vibration to the sewage pool. In the embodiment of the present application, the pulse start time can be understood as the moment when the control system sends a control signal to a sewage pool and starts the pulse generating device to apply vibration to the sewage pool.

[0077] The pulse end time refers to the end time point of applying pulse vibration to the sewage pool. In the embodiment of the present application, the pulse end time can be understood as the moment when the control system sends a control signal to a sewage pool to stop the pulse generating device from applying vibration to the sewage pool.

[0078] Specifically, the pulse response time data of each sewage pool after the initial parameter vibration is retrieved, and each sewage pool is sorted according to the length of the response time. The sewage pool with a short response time starts the pulse first, and the sewage pool with a long response time starts later. After calculating the response time of each sewage pool from the start of the pulse to stability, its start and end time are determined. The purpose of this arrangement is to make sewage pools with different response times achieve the effect of sequential vibration, rather than starting the pulse at the same time. The sewage pool with a fast response vibrates first, and the sewage pool with a slow response vibrates later, which can improve the overall treatment efficiency.

[0079] Step 321: Compare the start time of each pulse and the end time of each pulse with the preset standard pulse period to obtain the pulse time offset of each sewage pool.

[0080] Among them, the preset standard pulse period refers to a reasonable time range for pulse vibration treatment of a single sewage pool. In the embodiment of the present application, the preset standard pulse period can be understood as the appropriate pulse vibration duration range for the sewage pool determined based on experience.

[0081] The pulse time offset refers to the difference between the actual pulse vibration duration of the sewage pool and the preset standard pulse period. In the embodiment of the present application, the pulse time offset can be understood as the time difference between the total pulse duration calculated at the pulse start and end time of the sewage pool and the standard period.

[0082] Specifically, a standard pulse period is preset, for example, 30 minutes. Then the pulse start and end times of each sewage pool are taken in turn, and compared with the upper and lower limits of the standard period. If the limit is exceeded, the offset time is calculated. Finally, the pulse time offset data of each sewage pool is obtained. The purpose of this calculation is to determine whether the pulse time of each sewage pool meets expectations, whether the time is too long or too short. If the offset is too large, the timing needs to be adjusted. By comparing with the standard period to determine the offset, the pulse time imbalance of the abnormal sewage pool can be found, and targeted adjustments can be made to optimize the vibration time control of each sewage pool in the system to avoid the problem of too long or too short vibration time in a single sewage pool.

[0083] Step 331: All sewage pools whose pulse time offset is less than a preset pulse time offset are regarded as a synchronous pulse sewage pool group.

[0084] Specifically, the pulse time offset data of each sewage pool is counted, and a maximum allowable offset value is set as a threshold, and then the offset of each sewage pool is compared to see if it is lower than the threshold. The sewage pool with an offset lower than the threshold will be selected into the synchronous pulse sewage pool group. The purpose of this screening is to concentrate sewage pools with basically consistent pulse times in one group, and then formulate a unified synchronous control strategy for this group. By setting the offset threshold to extract the synchronous sewage pool, the pulse timing of each sewage pool in the synchronous group can be coordinated and consistent, providing support for group optimization of control parameters and improving system processing efficiency.

[0085] Step 302: Determine the sewage treatment efficiency of each sewage pool in the synchronous pulse sewage pool group within a preset period according to the pollutant purification amount, sewage temperature variable and sewage pH value variable of each sewage pool in the synchronous pulse sewage pool group.

[0086] Specifically, the pollutant purification amount, sewage temperature variable, and sewage pH value variable data of each sewage pool after the initial parameter vibration are retrieved. Then, according to the set evaluation period, such as 1 day, the average pollutant removal amount, average temperature change, and average pH change of each sewage pool during this period are calculated. Finally, the three indicators are combined to evaluate the sewage treatment efficiency of each sewage pool in a given period. The purpose of calculating the efficiency is to judge the differences in the response to the initial vibration parameters between the pools in the same group and to find the inefficient sewage pools. If the efficiency within the group is uneven, it is necessary to check the initial parameter settings and sewage characteristics. By evaluating the treatment efficiency of each sewage pool in the group, the parameters can be adjusted in a targeted manner so that the sewage pools in the group can achieve a consistent response and resonance synergy state, so as to improve the pulse vibration control effect of the group and the overall system.

[0087] Step 303: All sewage pools in the synchronous pulse sewage pool group whose sewage treatment efficiency is greater than the preset sewage treatment efficiency are taken as target sewage pools.

[0088] Specifically, the sewage treatment efficiency data of each sewage pool in the synchronization group is called, and an expected sewage treatment efficiency value is set as a threshold. The system then determines whether the efficiency of each sewage pool is greater than or equal to the threshold. If it is, the sewage pool is added to the target sewage pool set. Finally, a target sewage pool set with higher efficiency is obtained. The purpose of such screening is to select sewage pools with better treatment effects from the same group as samples for optimization tests. The parameter optimization results are also representative and can be extended to other sewage pools in the group. By pre-screening the target sewage pool based on efficiency, the subsequent parameter optimization test can be more targeted, avoiding detailed testing of all sewage pools in the group, improving test efficiency, and providing a reference for the coordinated control of the entire synchronization group.

[0089] Step 103: Adjust the pulse vibration frequency of each sewage pool according to the water quality parameters of each target sewage pool.

[0090] Among them, the pulse vibration frequency refers to the number of times pulse vibration is applied to the sewage pool per unit time. In the embodiment of the present application, the pulse vibration frequency can be understood as the frequency of pulse vibration of the sewage pool within a certain period of time, such as the number of vibrations per hour.

[0091] Specifically, retrieve the water quality parameter data of each target sewage pool, such as COD concentration, ammonia nitrogen content, etc. Set a higher or lower vibration frequency according to the parameter level. Then retrieve the pulse response time data of each target sewage pool, and set different vibration cycles according to the length of time. The purpose of adjusting the parameters is to enable each target sewage pool to reach a synchronous pulse state and ensure stable and efficient operation of the treatment system. If the pulses of any sewage pool are not synchronized, the synergy of the system will be reduced. By setting the frequency and period according to the water quality parameters and response time respectively, the individual characteristics of each sewage pool can be accurately matched, and personalized optimization of parameters can be achieved, so that the target sewage pool group forms a coordinated synchronous pulse vibration, thereby improving the sewage treatment efficiency through pulse vibration.

[0092] Based on the above embodiment, as an optional embodiment, in step 104: adjusting the pulse vibration frequency of each sewage pool according to the water quality parameters of each target sewage pool, this step may also include the following steps:

[0093] Step 401: Determine the target pulse vibration frequency of each target sewage pool according to the pollutant purification amount, sewage temperature variable and sewage pH value variable of each target sewage pool.

[0094] Specifically, the purification volume, temperature change, and pH change data of each target sewage pool are retrieved. Then, the three indicators are combined. If the purification volume is larger, the temperature change is smaller, and the pH change is smaller, a higher target vibration frequency is set; otherwise, a lower target frequency is set. The purpose of this determination is to link the target frequency with the water quality parameters, adjust the frequency according to the parameters, and achieve adaptive control. By intelligently matching the frequency according to the pollutant reduction, temperature stability, and pH stability, parameter adaptation can be achieved, so that the vibration frequency of each sewage pool is truly suitable for its water quality conditions, which not only ensures the treatment effect, but also avoids system overload.

[0095] Based on the above embodiment, as an optional embodiment, in step 401: according to the pollutant purification amount, sewage temperature variable and sewage pH value variable of each target sewage pool, the target pulse vibration frequency of each target sewage pool is determined. This step may also include the following steps:

[0096] Step 411: Substitute the pollutant purification amount, sewage temperature variable, and sewage pH value variable of each target sewage pool into a preset formula to calculate the target pulse vibration frequency of each target sewage pool;

[0097] The preset formula is:

[0098] ;

[0099] In the formula, represents the target pulse vibration frequency of the i-th target sewage pool, The proportionality constant representing the target pulse vibration frequency, The polynomial coefficients representing the amount of pollutant purification in the i-th target sewage pool, represents the pollutant purification amount of the i-th target sewage pool, Indicates the maximum pollutant purification capacity, Indicates the minimum pollutant purification amount, represents the polynomial coefficient of the sewage temperature variable in the i-th target sewage pool, represents the sewage temperature variable of the i-th target sewage pool, represents the maximum sewage temperature variable, represents the minimum sewage temperature variable, represents the polynomial coefficient of the pH value variable of the sewage in the i-th target sewage pool, represents the pH value variable of the sewage in the i-th target sewage pool, represents the maximum sewage pH value variable, represents the minimum sewage pH value variable, Indicates the proportion of sewage pools in the synchronous pulse mode in the pulse vibration, Indicates the proportion of sewage pools in asynchronous pulse mode in pulse vibration, represents the pulse time offset of the i-th target sewage pool, The upper limit of the polynomial degree representing the amount of pollutant purification, The upper limit of the polynomial degree representing the sewage temperature variable, The upper limit of the polynomial degree representing the wastewater pH value variable, The upper limit of the polynomial degree representing the pulse time offset.

[0100] The preset formula refers to a mathematical model formula for calculating the target pulse vibration frequency of each target sewage pool. In the embodiment of the present application, the preset formula can be understood as a multivariate analysis model including factors such as the amount of pollutant purification, sewage temperature variables, and sewage pH value variables. The preset formula is used to quantitatively calculate and evaluate the target pulse vibration frequency of each sewage pool. By substituting the actual detection data, the target pulse vibration frequency of each sewage pool can be calculated.

[0101] Specifically, a formula model for calculating the target frequency is established in advance, and the formula includes multiple parameters such as the amount of pollutant purification, temperature change, and pH change. Then, the three water quality parameter data of each target sewage pool are retrieved and substituted into the formula for calculation, and finally the target vibration frequency value corresponding to the target sewage pool is obtained. The purpose of this calculation is to make the frequency setting have a unified calculation standard to avoid subjective guesswork or experience setting. The formula combines the influence of multiple parameters on the frequency to calculate a more accurate target frequency. By substituting into the preset frequency calculation formula, the frequency setting can be made scientific and quantitative. The target frequency of each sewage pool has been calculated and reviewed by parameters, which can make the control more precise.

[0102] The formula consists of five parts. The first part This function represents the effect of the pollutant purification amount on the target pulse vibration frequency. This part of the function takes into account the pollutant purification amount in the sewage pool. The influence of , reflects the contribution of different pollutant purification amounts to the target pulse vibration frequency, the coefficient and pollutant purification The product of the sum and then normalized, and according to the maximum pollutant purification and minimum pollutant purification The difference between the values ​​of the pulse frequency and the value of the pulse frequency can be adjusted within the range of pollutant concentration. If a pollutant is determined to be more harmful to the environment through historical data and experiments, then The coefficient will be higher, the pollutant concentration The improvement of A positive coefficient will cause the value of this function to increase, indicating that the pulse vibration frequency needs to be increased to enhance the processing capacity, thus having a positive impact on the processing process.

[0103] Part 2 It represents the influence function of sewage temperature variable on target pulse vibration frequency. In this influence function, The coefficient usually reflects the effect of temperature on the treatment efficiency in different ranges. If the microbial activity in the treatment process is very sensitive to temperature, then within the ideal temperature range, the high temperature variable It can positively affect the metabolic activity of microorganisms, thereby increasing the efficiency of sewage treatment. However, if the temperature exceeds the activity range of microorganisms, it will have a negative impact. and minimum pollutant purification The difference ensures that the temperature is within the ideal range. The increase in temperature usually accelerates the reaction rate, which is conducive to the rapid treatment of pollutants in sewage. This is a positive effect. If the temperature is too high or too low, it may inhibit the activity of microorganisms or make certain chemical reactions unfavorable. This is a negative effect.

[0104] Part 3 Represents the influence function of sewage pH value variable on target pulse vibration frequency, The coefficient indicates the pH value of sewage at the maximum sewage pH value variable Variable with minimum wastewater pH The effect of pH on treatment efficiency within a certain range. Microorganisms have a relatively fixed pH activity range. When the pH value is within this range, it has a positive effect on sewage treatment. If the pH value deviates from this range, the treatment efficiency will decrease, which is a negative impact. Therefore, this function can adjust the pulse vibration frequency to adapt to the change of pH value to maintain treatment efficiency.

[0105] Proportional constant of target pulse vibration frequency , used to adjust the influence of the pollutant purification amount, sewage temperature variable and sewage pH value variable on the target pulse vibration frequency in the first part, the second part and the third part, and the proportional constant of the target pulse vibration frequency It is obtained by analyzing the mapping relationship between the pollutant purification amount, sewage temperature variable, sewage pH value variable and the target pulse vibration frequency in the experimental data.

[0106] Part 4 It represents the influence function of the proportion of synchronous pulse mode and asynchronous pulse mode sewage pool on the target pulse frequency, where is the percentage of sewage pools in synchronous pulse mode, and It is the proportion of sewage pools in asynchronous pulse mode. This factor helps adjust the vibration frequency to adapt to the dynamics of the entire treatment system. During the entire pulse vibration process, the more sewage pools in synchronous pulse mode, the larger the target pulse frequency needs to be adjusted, and the more sewage pools in asynchronous pulse mode, the smaller the target pulse frequency needs to be adjusted.

[0107] Part 5 Indicates the possible pulse time offset for each target cesspool The influence function of the target pulse vibration frequency takes into account the pulse time error of each sewage pool due to actual operation deviation, which causes the incoordination of pulse vibration in different sewage pools. The larger the pulse time offset, the larger the target pulse vibration frequency that needs to be adjusted, and the smaller the pulse time offset, the smaller the target pulse vibration frequency that needs to be adjusted.

[0108] In summary, at high pollutant concentrations, a higher pulse vibration frequency may be required to accelerate the decomposition or removal of pollutants, because more frequent vibrations can increase the contact frequency between the treatment medium and pollutants. When the sewage temperature variable is too low, the pulse vibration frequency needs to be increased to help activate microorganisms or accelerate certain slow chemical reactions. If the sewage temperature variable is too high, the frequency needs to be reduced to avoid heat stress on microorganisms. At extreme pH values, the pulse vibration frequency may need to be adjusted to optimize the treatment effect. For example, in an acidic or alkaline environment, the activity of microorganisms may decrease, so it may be necessary to adjust the pulse vibration frequency to compensate for the decrease in treatment efficiency. When a large pulse vibration deviation occurs in the sewage pool, the target pulse vibration frequency should be adjusted. When treating sewage through pulse vibration, the synergy between sewage pools should be improved to achieve efficient and stable sewage treatment effects.

[0109] Step 402: Based on the target pulse vibration frequency of each target sewage pool, adjust the pulse vibration frequency of each sewage pool.

[0110] Specifically, the target vibration frequency value determined by each target sewage pool is called. Then, it is compared with the current vibration frequency of each sewage pool to determine whether the current frequency meets the target frequency. If not, the vibration system of the corresponding sewage pool is controlled to operate at the target frequency according to the target frequency setting instruction. The purpose of such adjustment is to achieve closed-loop control of parameters, so that the actual vibration frequency of the sewage pool can adapt to the changes in its water quality state and achieve dynamic adjustment that matches the water quality.

[0111] Based on the above embodiment, as an optional embodiment, in step 103: according to the water quality parameters of each target sewage pool, the pulse vibration frequency of each sewage pool is adjusted. After this step, the following steps may also be included:

[0112] Step 501: Determine the minimum pulse response time among the pulse response times of the target sewage pools.

[0113] Specifically, the initial parameter vibration of each target sewage pool is called to reach stable pulse response time data. Then compare the response time of each sewage pool, and select the response time of the sewage pool with the shortest time and the fastest response as the minimum response time. The purpose of this determination is to find the fastest response time value among all sewage pools, and use it as a benchmark to set the overall vibration cycle, so as to ensure that all sewage pools can adapt to this cycle vibration. After finding the minimum response time, the global cycle can be set based on this standard, so that all sewage pools can achieve synchronous vibration with this cycle.

[0114] Step 502: Determine the pulse vibration interval duration and the pulse vibration duration according to the pulse signal corresponding to the minimum pulse response time; determine the target pulse vibration period based on the pulse vibration interval duration and the pulse vibration duration.

[0115] Among them, the pulse vibration cycle refers to the time interval for pulse vibration of the sewage pool. In the embodiment of the present application, the pulse vibration cycle can be understood as the time period between one pulse vibration of the sewage pool and the next pulse vibration.

[0116] Specifically, the complete pulse signal curve corresponding to the minimum response time is retrieved, the curve waveform is analyzed, and the interval and duration of a pulse are measured. Then the two are added together to obtain the duration of a complete pulse cycle, which is used as the target pulse vibration cycle for all sewage pools. The purpose of setting the cycle in this way is to obtain the exact timing parameters by analyzing the vibration curve of the minimum response time, so that the target cycle setting is accurate and feasible. By analyzing the signal curve to obtain the interval and duration, the cycle duration can be calculated accurately to ensure that it meets the minimum response time, and each sewage pool can be adjusted to adapt to the cycle vibration to achieve pulse vibration synchronization.
