Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present invention.

[0022] Embodiment 1, as Figure 1 As shown, the embodiment of the present invention provides a sewage treatment dosing control method for a magnetic coagulation sedimentation tank, which specifically includes the following steps:

[0023] A100: Obtain a target sewage category of target sewage to be treated, and obtain a treatment standard of the target sewage category by index, wherein the treatment standard includes multiple indicator standards of multiple treatment indicators.

[0024] Furthermore, the present invention A100 also includes:

[0025] A110: Obtain a target sewage category of target sewage to be treated; A120: According to the target sewage category, obtain a treatment standard of the target sewage category by indexing, wherein the treatment standard includes multiple indicator standards of multiple treatment indicators.

[0026] Specifically, first, the target sewage category of the target sewage to be treated is obtained, wherein the target sewage category includes domestic sewage (kitchen wastewater, toilet wastewater, etc.), industrial sewage (chemical sewage, food processing sewage, pharmaceutical sewage, etc.), municipal comprehensive sewage (mixed with domestic sewage and part of industrial sewage), agricultural sewage, etc. Then, the treatment standard index is performed according to the target sewage category to obtain the treatment standard of the target sewage category, such as by querying information through a sewage treatment database; wherein the treatment standard includes multiple indicator standards of multiple treatment indicators, such as chemical oxygen demand, biochemical oxygen demand, suspended solids concentration, ammonia nitrogen concentration, etc. For example, the chemical oxygen demand of domestic sewage is less than or equal to 50 mg / L, and the chemical oxygen demand of industrial sewage is less than or equal to 100 mg / L; the ammonia nitrogen concentration of domestic sewage is less than or equal to 1 mg / L, and the ammonia nitrogen concentration of industrial sewage is less than or equal to 5 mg / L.

[0027] By obtaining the treatment standards of the target sewage categories through indexing, the specific requirements for sewage treatment can be clarified, providing a scientific basis for parameter optimization and precise control of subsequent sewage treatment processes, ensuring comprehensive improvement in sewage treatment efficiency and quality.

[0028] A200: Detect the target sewage for the multiple treatment indicators to obtain multiple treatment indicator parameters, calculate and obtain multiple treatment indicator parameter deviations in combination with the indicator standards, and comprehensively rank the multiple treatment indicators according to the multiple treatment indicator parameter deviations and the target sewage category to obtain multiple indicator rankings.

[0029] Furthermore, the present invention A200 also includes:

[0030] A210: Detect the multiple treatment indicators of the target sewage to obtain multiple treatment indicator parameters, wherein the multiple treatment indicators include chemical oxygen demand, biochemical oxygen demand, suspended solids, and ammonia nitrogen; A220: Calculate the ratio of the difference between the multiple treatment indicator parameters and the multiple indicator standards to the multiple indicator standards to obtain multiple treatment indicator parameter deviations.

[0031] Specifically, first, a plurality of treatment indicators are obtained, wherein the plurality of treatment indicators include chemical oxygen demand, biochemical oxygen demand, suspended solids and ammonia nitrogen; then, the target sewage is tested according to the plurality of treatment indicators to obtain specific values ​​of key pollution indicators (chemical oxygen demand, biochemical oxygen demand, suspended solids, ammonia nitrogen), wherein the indicator detection method can be selected according to actual conditions, for example, chemical oxygen demand is detected by the dichromate method, and biochemical oxygen demand is determined by the dilution and seed mud method; a plurality of treatment indicator parameters are obtained, wherein the treatment indicator parameters refer to specific values ​​of indicators, such as chemical oxygen demand of 80 mg / L, biochemical oxygen demand of 15 mg / L, suspended solids concentration of 20 mg / L, ammonia nitrogen concentration of 3 mg / L, etc.

[0032] Next, the difference between the multiple processing index parameters and the multiple index standards is calculated to obtain multiple index parameter deviations; the ratio of the index parameter deviation to the index standard is further calculated, and the ratio is set as the processing index parameter deviation to obtain multiple processing index parameter deviations, wherein the larger the processing index parameter deviation is, the more serious the degree of exceeding the standard of the characterization index is, and priority treatment is required; for example, assuming that the processing index parameter is 80 mg / L of chemical oxygen demand and the corresponding index standard is 50 mg / L, the index parameter deviation is 30 mg / L, and the processing index parameter deviation corresponding to the chemical oxygen demand is 30 / 50, i.e., 0.6.

[0033] A230: According to the deviations of the multiple treatment index parameters, multiple first index ranking values ​​are obtained by sorting, and multiple second index ranking values ​​are obtained according to the target sewage category. Combined with the multiple first index ranking values, multiple comprehensive index ranking values ​​are obtained by processing, and multiple index rankings are obtained by sorting.

[0034] Further, the present invention A230 also includes:

[0035] A231: Sort the multiple treatment indicators in order from large to small according to the deviations of the multiple treatment indicator parameters to obtain multiple first indicator ranking values; A232: Obtain multiple second indicator ranking values ​​of the multiple treatment indicators corresponding to the target sewage category, wherein the second indicator ranking values ​​of the multiple treatment indicators of different sewage categories are different; A233: Calculate the mean of the multiple first indicator ranking values ​​and the multiple second indicator ranking values ​​to obtain multiple comprehensive indicator ranking values, and sort them in order from small to large to obtain multiple indicator rankings.

[0036] Specifically, the multiple treatment indicators are arranged in descending order according to the corresponding multiple treatment indicator parameter deviations to obtain multiple first indicator ranking values. For example, assuming that the multiple treatment indicator parameter deviations are chemical oxygen demand 0.6, biochemical oxygen demand 0.8, suspended solids 0.4, and ammonia nitrogen 0.2, the multiple first indicator ranking values ​​are biological oxygen demand 1, chemical oxygen demand 2, suspended solids 3, and ammonia nitrogen 4. Through the ranking, the key indicators that need to be treated first can be clarified, and resources can be concentrated to solve the most serious pollution problems.

[0037] Next, obtain multiple second indicator ranking values ​​of the multiple treatment indicators corresponding to the target sewage category, wherein the second indicator ranking value refers to the indicator priority preset according to the typical characteristics of the sewage category and the concentration of the main pollutants, which can be obtained through historical sewage treatment data statistics. The second indicator ranking values ​​of the multiple treatment indicators of different sewage categories are different; for example, domestic sewage usually pays more attention to organic pollutants and nitrogen and phosphorus pollutants; while industrial sewage pays more attention to suspended matter or pollutants in specific industries. Assuming that according to historical sewage treatment data statistics, the chemical oxygen demand concentration in domestic sewage in this area is relatively high and accounts for the largest proportion, the second indicator ranking of chemical oxygen demand is 1.

[0038] Then, based on the multiple first index ranking values ​​and the multiple second index ranking values, the first index ranking value and the second index ranking value of each same treatment index are averaged to obtain multiple comprehensive index ranking values. For example, assuming that the first index ranking of chemical oxygen demand is 2 and the second index ranking is 1, the comprehensive index ranking value is 1.5. Then, the multiple treatment indexes are arranged in order from small to large according to the corresponding multiple comprehensive index ranking values ​​to obtain multiple index rankings corresponding to the multiple treatment indexes. For example, assuming that the multiple comprehensive index ranking values ​​are chemical oxygen demand 1.5, biochemical oxygen demand 2, suspended solids 2.5, and ammonia nitrogen 4, the multiple index rankings are chemical oxygen demand 1, biochemical oxygen demand 2, suspended solids 3, and ammonia nitrogen 4. By calculating and obtaining multiple index rankings corresponding to multiple treatment indexes, the importance of each treatment index can be scientifically evaluated, and the treatment indexes with higher rankings can be treated preferentially, thereby improving the scientificity and efficiency of sewage treatment.

[0039] A300: Obtain the dosing control parameter space of the magnetic coagulation sedimentation tank, optimize the dosing control parameters within the dosing control parameter space according to the multiple treatment index parameters and multiple index rankings, and obtain the optimal dosing control parameters, wherein, during the optimization process, optimization is performed according to the multiple index rankings and the inferiority avoidance strategy.

[0040] Furthermore, the present invention A300 also includes:

[0041] A310: Obtaining the dosing control parameter space of the magnetic coagulation sedimentation tank, wherein the dosing control parameters include dosing agent ratio and dosing amount; A320: Randomly generating multiple first dosing control parameters in the dosing control parameter space; A330: Performing sewage treatment prediction based on the multiple first dosing control parameters and the multiple treatment index parameters, and obtaining multiple first prediction treatment index parameter sets, wherein a sample dosing control parameter set, multiple sample treatment index parameter sets and multiple sample prediction treatment index parameter sets are collected, and a coagulation treatment predictor is trained to perform sewage treatment prediction.

[0042] Specifically, first, the dosing control parameters of the magnetic coagulation sedimentation tank are obtained, wherein the dosing control parameters include the dosing agent ratio (referring to the ratio of flocculants, coagulants and magnetic powder) and the dosing amount (the specific amount of each agent required in a unit of sewage); and the dosing control parameter space is obtained, and the dosing control parameter space refers to the combination range of all possible dosing parameters. Then, multiple dosing control parameters are randomly selected in the dosing control parameter space as the first dosing control parameters, and multiple first dosing control parameters are obtained.

[0043] On the other hand, a coagulation treatment predictor is constructed based on a BP neural network. The coagulation treatment predictor is a BP neural network model that can be iteratively optimized in machine learning and is used for sewage treatment prediction. The coagulation treatment predictor includes an input layer, multiple hidden layers and an output layer, wherein the input data of the input layer are dosing control parameters and multiple treatment index parameters, and the output data of the output layer are multiple prediction treatment index parameters (i.e., index parameter values ​​after processing); then a set of sample dosing control parameters, a set of multiple sample treatment index parameters and a set of multiple sample prediction treatment index parameters are collected as training data, and the sample dosing control parameters and multiple sample treatment index parameters are used as inputs, and multiple sample prediction treatment index parameters are used as outputs to perform supervised training on the coagulation treatment predictor. First, the sample input data is propagated layer by layer through the input layer and the hidden layer to the output layer to calculate the predicted value; then, the error between the predicted value and the actual value is calculated using a loss function, and the gradient of each layer is calculated using an error back propagation algorithm to update the weight and bias; then forward propagation, error calculation, and back propagation are repeated, and the model parameters are iteratively updated until the value of the loss function is less than the set threshold, and the coagulation treatment predictor converges.

[0044] Then, each first dosing control parameter and a plurality of treatment index parameters are combined and input into the coagulation treatment predictor to perform sewage treatment prediction, and a plurality of first prediction treatment index parameter sets corresponding to the plurality of first dosing control parameters are output. By constructing a coagulation treatment predictor to perform sewage treatment prediction, the intelligence and scientificity of sewage treatment prediction can be improved, thereby improving the accuracy and efficiency of the predicted treatment index parameter set.

[0045] A340: Calculate and obtain multiple first dosage fitnesses according to the multiple first prediction processing indicator parameter sets.

[0046] Further, the present invention A340 also includes:

[0047] A341: Calculate and obtain multiple first dosing fitnesses according to the multiple first prediction processing index parameter sets, as shown in the following formula: ; Among them, AFIT is the dosage fitness, M is the number of multiple treatment indicators, K i is the predicted processing index parameter of the ith processing index in the predicted processing index parameter set, K y is the indicator standard of the i-th processing indicator.

[0048] Specifically, construct the fitness calculation function: ; In the dosing fitness calculation function, AFIT is the dosing fitness. The larger the dosing fitness, the smaller the comprehensive concentration of pollutants representing multiple treatment indicators after the predicted treatment. For example, if it is smaller than the corresponding pollutant concentration index standard, the better the sewage treatment effect; M is the number of multiple treatment indicators, K i is the predicted processing index parameter of the ith processing index in the predicted processing index parameter set, K y is the index standard of the i-th treatment index. By constructing the dosing fitness calculation function, the sewage treatment effect can be scientifically evaluated, providing a basis for the subsequent optimization of dosing control parameters, and at the same time improving the accuracy and reliability of the optimization of dosing control parameters.

[0049] A350: According to the multiple first dosage fitnesses, screen and obtain the inferior first dosage control parameters, and based on the inferior first prediction processing index parameter set of the inferior first dosage control parameters and based on the inferior avoidance strategy, adjust and optimize the other multiple first dosage control parameters to obtain multiple second dosage control parameters.

[0050] Furthermore, the present invention A350 also includes:

[0051] A351: Filter the smallest first dosing fitness among the multiple first dosing fitnesses, and set the first dosing control parameter corresponding to the smallest first dosing fitness as the inferior first dosing control parameter; A352: Obtain a preset adjustment step for adjusting the dosing control parameter; A353: Obtain a set of inferior first prediction processing index parameters of the inferior first dosing control parameter, sort the multiple indexes, and calculate and configure multiple optimized adjustment steps for adjusting the other multiple first dosing control parameters, as shown in the following formula: ; Among them, SL t To optimize the adjustment step size, SL y is the preset adjustment step, M is the number of multiple processing indicators, and wi is the weight assigned according to the indicator ranking of the i-th processing indicator, is the first predicted processing index parameter of the i-th processing index in the first predicted processing index parameter set of other first dosing control parameters, A354: adopting the multiple optimization adjustment steps, adjusting and optimizing the other multiple first dosing control parameters in the direction away from the inferior first dosing control parameter, to obtain multiple second dosing control parameters.

[0052] Specifically, first, the smallest first dosing fitness among the multiple first dosing fitnesses is selected, and the first dosing control parameter corresponding to the smallest first dosing fitness is set as the inferior first dosing control parameter, wherein the inferior first dosing control parameter represents the worst sewage treatment effect, and it is necessary to stay away from the inferior first dosing control parameter during the optimization process. Next, the preset adjustment step length for adjusting the dosing control parameter is obtained, wherein the preset adjustment step length refers to the amplitude of the dosing control parameter adjustment during each optimization process, including the dosing agent ratio adjustment step length and the dosing amount adjustment step length, which can be set according to the actual situation, such as setting the dosing agent ratio adjustment step length to 0.01 and the dosing amount adjustment step length to 1 mg / L.

[0053] Next, the inferior first prediction processing index parameter set of the inferior first dosing control parameter is obtained, and an optimization adjustment step length calculation function is constructed based on the inferior first prediction processing index parameter set: ; In the optimization adjustment step size calculation function, SL t To optimize the adjustment step size, SL y is the preset adjustment step, M is the number of multiple processing indicators, and w i is the weight assigned according to the indicator ranking of the i-th processing indicator, wherein the smaller the indicator ranking, the greater the weight of the corresponding processing indicator, for example, the inverse of the ratio of the indicator ranking of each processing indicator to the sum of multiple indicator rankings is calculated to obtain multiple ratio inverses, and then the ratio of each ratio inverse to the sum of multiple ratio inverses is calculated as the weight, the smaller the ranking, the greater the weight; is the first predicted processing index parameter of the i-th processing index in the first predicted processing index parameter set of other first dosing control parameters, The inferior first prediction processing index parameter of the i-th processing index in the inferior first prediction processing index parameter set of the inferior first dosing control parameter is then used to calculate and configure multiple optimization adjustment step lengths for adjusting the other multiple first dosing control parameters according to the sorting of the multiple indicators, thereby obtaining multiple optimization adjustment step lengths.

[0054] By constructing an optimization adjustment step calculation function, the matching optimization adjustment step can be set according to the quality of the first dosing control parameter. That is, when the sewage treatment prediction effect of the first dosing control parameter is better, that is, the smaller the pollutant concentration, the smaller the numerator in the formula The smaller it is, the smaller the optimization adjustment step is, the more refined the optimization is, and the accuracy of parameter optimization can be improved; when the sewage treatment prediction effect of the first dosage control parameter is poor, that is, the higher the pollutant concentration, the larger the optimization adjustment step is, which is used to improve the optimization efficiency; by combining the ranking and weighting of multiple indicators to calculate the adjustment step, the importance of priority indicators can be highlighted, and key pollution indicators (higher rankings) can be optimized more finely, thereby further improving the accuracy and reliability of dosage control parameter optimization.

[0055] Furthermore, the direction away from the inferior first dosing control parameter is used as the parameter adjustment direction, and the other multiple first dosing control parameters are adjusted and optimized according to the multiple optimization adjustment steps to obtain multiple second dosing control parameters. By setting the inferior avoidance strategy and the optimization adjustment step to perform parameter optimization, the dosing parameters can be adjusted in the optimization direction so that the new dosing combination has a better treatment effect; at the same time, the step size is adjusted to be larger for the combination with poor effect, quickly away from the inferior parameter, and the optimization efficiency is improved; the step size is adjusted to be smaller for the combination with better effect, and fine optimization is achieved; thereby significantly improving the accuracy and efficiency of the optimization of the dosing control parameters.

[0056] A360: Continue to predict and calculate the dosage fitness of the multiple second dosage control parameters, and continue to update the inferior dosage control parameters and optimize the dosage control parameters until the optimization converges, output the dosage control parameter with the largest dosage fitness, and obtain the optimal dosage control parameter.

[0057] Specifically, using the same method as above, continue to predict and calculate the dosage fitness of the multiple second dosage control parameters to obtain multiple second dosage fitnesses; then select the smallest dosage fitness among the multiple second dosage fitnesses as the inferior second dosage control parameter, and use the inferior second dosage control parameter as a benchmark to continue to optimize the dosage control parameter until a predetermined number of optimizations is reached, then stop optimizing, and output the dosage control parameter with the largest current dosage fitness as the optimal dosage control parameter.

[0058] A400: Adopting the optimal dosing control parameters, dosing treatment is performed on the magnetic coagulation sedimentation tank to treat the target sewage.

[0059] Specifically, the optimal dosing control parameters are finally used to carry out dosing treatment on the magnetic coagulation sedimentation tank, that is, the reagent solution is configured according to the optimal dosing control parameters (including the dosing reagent ratio and the dosing reagent amount), and the target sewage is treated by the magnetic coagulation sedimentation tank with the reagent solution configured.

[0060] The sewage treatment dosing control method of the magnetic coagulation sedimentation tank provided in the embodiment of the present invention has at least the following technical effects:

[0061] The target sewage category of the target sewage is obtained and the treatment standard is obtained by indexing; then, multiple treatment indexes are detected for the target sewage to obtain multiple treatment index parameters, multiple treatment index parameter deviations are calculated in combination with the index standard, and multiple treatment indexes are comprehensively ranked according to the multiple treatment index parameter deviations and the target sewage category to obtain multiple index rankings; further, according to the multiple treatment index parameters and the multiple index rankings, the dosing control parameters are optimized within the dosing control parameter space to obtain the optimal dosing control parameters; finally, the optimal dosing control parameters are used to perform dosing treatment on the magnetic coagulation sedimentation tank to perform sewage treatment of the target sewage; the above method can improve the scientificity and accuracy of the dosing control parameter setting, which can not only improve the resource utilization efficiency, but also ensure that the sewage treatment effect meets the standards, thereby achieving the high efficiency, economy and environmental protection of sewage treatment, and improving the sewage treatment efficiency and treatment quality.
