[0042] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.
[0043] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0045] The terms "first", "second", etc. in the specification and claims of the present invention are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0046] When describing the embodiments of the present invention, some concepts used in the following description are first explained.
[0047] Aeration is an important part of sewage treatment. It injects air or oxygen into sewage through a blower to promote the degradation and oxidation of organic matter in sewage and increase the dissolved oxygen content in sewage, thereby effectively removing organic matter and odor in sewage and improving treatment efficiency.
[0048] The embodiment of the present invention, as Figure 1 As shown, an aeration control method is provided, comprising:
[0049] S101, obtaining blower aeration parameters and corresponding water quality related parameters of the sewage treatment system at the current moment.
[0050] Optionally, the blower aeration includes at least one of the following:
[0051] Blower aeration frequency; Blower aeration duration.
[0052] The blower aeration frequency can be understood as the operating frequency of the blower in a single cycle, and the adjustable range is, for example, 38 Hz to 50 Hz; the blower aeration duration can be understood as the operating duration of the blower in a single cycle, and the adjustable range is, for example, 8 min to 20 min.
[0053] Optionally, the water quality related parameters include at least one of the following:
[0054] Influent ammonia nitrogen concentration; influent water volume; ammonia nitrogen concentration in the anoxic zone (the anoxic zone can be called anaerobic and anoxic zone); ammonia nitrogen concentration in the aerobic zone; dissolved oxygen concentration in the aerobic zone.
[0055] It should be noted that the sewage treatment system includes a sewage pool. Optionally, the sewage pool is a sewage pool using a Vertical Flow Labyrinth (VFL) process, and the sewage pool includes anaerobic and anoxic zones; an aerobic zone; and a sedimentation zone. Among them, the anaerobic and anoxic zones are used for anaerobic and anoxic treatment of sewage; in the aerobic zone, a membrane microporous aerator is installed at the bottom of the pool, and a blower aerates from here; the mixed liquid in the aerobic zone flows into the sedimentation zone through the gaps in the partition, and the flow rate decreases from bottom to top, the sludge settles, and the upper clear water flows into the stainless steel drain trough and is discharged.
[0056] Sewage flows into the sewage pool from the water inlet, passes through the anaerobic and anoxic zones, aerobic zones and sedimentation zones in turn, and finally flows out of the treated sewage from the water outlet. The entire sewage treatment process from the water inlet to the water outlet takes a certain amount of time and has a large time lag. Therefore, the treatment effect of the blower aeration parameters at the current moment on the sewage cannot be indicated by the water quality-related parameters at the current moment. In other words, the water quality-related parameters at a certain historical moment correspond to the blower aeration parameters at the current moment.
[0057] Therefore, in order to ensure the consistency and synchronization of data and improve the prediction accuracy of the effluent ammonia nitrogen classification model, it is necessary to obtain the blower aeration parameters of the sewage treatment system at the current moment and the water quality related parameters at the target moment corresponding to the blower aeration parameters at the current moment.
[0058] Furthermore, the aeration control method described in the embodiment of the present invention can be applied to a server of a sewage treatment system, and the server obtains the blower aeration parameters and corresponding water quality related parameters of the sewage treatment system at the current moment through sensors. Through the blower aeration parameters and corresponding water quality related parameters collected in real time, the sewage treatment process can be accurately understood, providing data support for the subsequent aeration control process and avoiding manual operation.
[0059] S102, inputting the blower aeration parameters and the water quality related parameters into a pre-acquired effluent ammonia nitrogen classification model to obtain an effluent ammonia nitrogen water quality classification result; the effluent ammonia nitrogen classification model is used to classify and predict the water quality of effluent ammonia nitrogen according to the blower aeration parameters and the water quality related parameters.
[0060] In an embodiment of the present invention, the blower aeration parameters and the water quality related parameters are input into an outlet ammonia nitrogen classification model, so as to obtain a prediction classification result of the outlet ammonia nitrogen water quality corresponding to the blower aeration parameters at the current moment.
[0061] Optionally, the blower aeration parameters and the water quality related parameters are input into an effluent ammonia nitrogen classification model to obtain an effluent ammonia nitrogen concentration and an effluent ammonia nitrogen water quality classification result corresponding to the effluent ammonia nitrogen concentration.
[0062] It should be noted that the effluent ammonia nitrogen water quality classification result is one of the following four:
[0063] Excellent; Good; Marginal; Exceeded.
[0064] The effluent ammonia nitrogen water quality classification result is related to the effluent ammonia nitrogen concentration. Taking the effluent ammonia nitrogen water quality standard limit of 1.5 g / ml as an example:
[0065] When the effluent ammonia nitrogen concentration is less than 0.2 g / ml, the effluent ammonia nitrogen water quality classification result is marked as "excellent";
[0066] When the effluent ammonia nitrogen concentration is 0.2 g / ml≤<1 g / ml, the effluent ammonia nitrogen water quality classification result is marked as "good";
[0067] When the effluent ammonia nitrogen concentration is 1 g / ml≤<1.5 g / ml, the effluent ammonia nitrogen water quality classification result is marked as "critical";
[0068] When the effluent ammonia nitrogen concentration is ≥1.5 g / ml, the effluent ammonia nitrogen water quality classification result is marked as "exceeding the standard".
[0069] S103, adjusting the blower aeration parameters according to the effluent ammonia nitrogen water quality classification result.
[0070] In an embodiment of the present invention, the aeration parameters of the blower are adjusted according to the effluent ammonia nitrogen water quality classification result to achieve intelligent aeration control guided by the effluent ammonia nitrogen reaching the standard, with high control accuracy, good sewage treatment effect and reduced energy consumption.
[0071] In one embodiment, optionally, S101, obtaining the blower aeration parameters and corresponding water quality related parameters of the sewage treatment system at the current moment includes:
[0072] Collecting blower aeration parameters of the sewage treatment system at the current moment and water quality related parameters within a preset time period before the current moment;
[0073] A time series alignment process is performed on the blower aeration parameter at the current moment and the water quality related parameter within the preset time length to obtain the water quality related parameter corresponding to the blower aeration parameter at the current moment.
[0074] In the embodiment of the present invention, the blower aeration parameters of the sewage treatment system at the current moment and the water quality related parameters within a preset time period before the current moment are collected by sensors.
[0075] It should be noted that the time series alignment process is to obtain the water quality related parameters at the target historical moment corresponding to the blower aeration parameters at the current moment from the water quality related parameters within the preset time period.
[0076] Optionally, the sensor includes at least: a flow meter, an online ammonia nitrogen analyzer and an online dissolved oxygen detector.
[0077] Optionally, the amount of water entering within the preset time period is collected by a flow meter.
[0078] Optionally, the ammonia nitrogen concentration in the inlet water, the ammonia nitrogen concentration in the anoxic zone and the ammonia nitrogen concentration in the aerobic zone within the preset time period are collected by an ammonia nitrogen online analyzer in the corresponding area of the sewage pool.
[0079] Optionally, the ammonia nitrogen concentration in the aerobic zone within the preset time period is collected by an online dissolved oxygen detector.
[0080] Optionally, the preset duration is 24 hours.
[0081] Optionally, the collection frequency of the water quality related parameters within the preset time period, including the inlet ammonia nitrogen concentration, the anoxic zone ammonia nitrogen concentration, the aerobic zone ammonia nitrogen concentration and the aerobic zone dissolved oxygen concentration, is 60 seconds.
[0082] Optionally, the water volume in the water quality related parameters within the preset time period needs to be collected when there is a change.
[0083] It should be noted that, since the blower aeration parameters also need to be collected when they change, the blower aeration parameters may change at the current moment; of course, the blower aeration parameters may not change at the current moment.
[0084] In one embodiment, optionally, in S103, adjusting the aeration parameters of the blower according to the effluent ammonia nitrogen water quality classification result includes:
[0085] According to the control strategy corresponding to the effluent ammonia nitrogen water quality classification result, the blower aeration adjustment direction and the blower aeration adjustment parameter are obtained; the control strategy is used to indicate the blower aeration adjustment direction and the blower aeration adjustment parameter corresponding to different effluent ammonia nitrogen water quality classification results;
[0086] The aeration parameters of the blower are adjusted according to the aeration adjustment direction of the blower and the aeration adjustment parameters of the blower.
[0087] In an embodiment of the present invention, the control strategy includes at least one of the following:
[0088] The effluent ammonia nitrogen water quality classification result is "excellent" and the blower aeration parameter does not reach the minimum limit, and accordingly, the blower aeration adjustment direction is the parameter reduction direction, and the blower aeration adjustment parameter is the first preset value;
[0089] The effluent ammonia nitrogen water quality classification result is "good", and correspondingly, the blower aeration adjustment direction is no adjustment direction, and the blower aeration adjustment parameter is 0;
[0090] The effluent ammonia nitrogen water quality classification result is "critical" and the blower aeration parameter has not reached the maximum limit, and accordingly, the blower aeration adjustment direction is the parameter increase direction, and the blower aeration adjustment parameter is the second preset value;
[0091] The effluent ammonia nitrogen water quality classification result is "exceeding the standard", and correspondingly, the blower aeration adjustment direction is the parameter increasing direction, and the blower aeration adjustment parameter is the third preset value.
[0092] The second preset value may be equal to the third preset value.
[0093] Next, according to the aeration adjustment direction and aeration adjustment parameters indicated by the above control strategy, the aeration parameters of the blower are adjusted. For example, if the effluent ammonia nitrogen water quality classification result is "critical" and the aeration parameters of the blower have not reached the maximum limit, the aeration parameters of the blower at the current moment are increased by a second preset value in the direction of parameter increase to obtain the adjusted aeration control parameters.
[0094] In one embodiment, optionally, the method further comprises:
[0095] Inputting the adjusted blower aeration parameters into the effluent ammonia nitrogen classification model to obtain an adjusted effluent ammonia nitrogen water quality classification result;
[0096] According to the adjusted effluent ammonia nitrogen water quality classification result, the blower aeration parameters are repeatedly adjusted until the effluent ammonia nitrogen water quality classification result meets the preset classification result.
[0097] In an embodiment of the present invention, the adjusted blower aeration parameters and the water quality related parameters corresponding to the blower aeration parameters at the current moment are input into the effluent ammonia nitrogen classification model to obtain the adjusted effluent ammonia nitrogen water quality classification results, wherein the blower aeration parameters at the current moment are the blower aeration parameters before adjustment.
[0098] Here, after obtaining the adjusted effluent ammonia nitrogen water quality classification result, it is necessary to determine whether the adjusted effluent ammonia nitrogen water quality classification result meets the preset classification result. Taking the preset classification result as "good" as an example, if the adjusted effluent ammonia nitrogen water quality classification result is "critical", which means that it does not meet the preset classification result, the blower aeration parameters are repeatedly adjusted to obtain repeatedly adjusted blower aeration parameters, until the repeatedly adjusted blower aeration parameters are input into the effluent ammonia nitrogen classification model, and an effluent ammonia nitrogen water quality classification result that meets the preset classification result is obtained, and the adjustment is ended.
[0099] In one embodiment, optionally, the method further comprises:
[0100] According to the following steps, the effluent ammonia nitrogen classification model is obtained:
[0101] Acquire historical data of the sewage treatment system; the historical data includes water quality related parameters, effluent ammonia nitrogen concentration and blower aeration parameters at different times;
[0102] Performing time series alignment processing on the historical data to obtain processed historical data; the processed historical data includes the effluent ammonia nitrogen concentration and the blower aeration parameter at the second historical moment corresponding to the water quality related parameters at the first historical moment, and the blower aeration parameter at the third historical moment corresponding to the water quality related parameters at the first historical moment;
[0103] Using the water quality related parameters and blower aeration parameters in the processed historical data as input features and the effluent ammonia nitrogen concentration in the processed historical data as a target feature, training a machine learning model to obtain a trained machine learning model;
[0104] The effluent ammonia nitrogen classification model is constructed based on the effluent ammonia nitrogen concentration, the ammonia nitrogen water quality standard limit and the trained machine learning model.
[0105] In the embodiment of the present invention, before performing time series alignment processing on the historical data, the method may further include:
[0106] Calculating the time correlation between the inlet ammonia nitrogen concentration, the anoxic zone ammonia nitrogen concentration and the aerobic zone ammonia nitrogen concentration at each historical moment in the historical data, that is, performing time delay analysis on the water inlet, the anoxic zone and the aerobic zone;
[0107] According to the time correlation between the influent ammonia nitrogen concentration, the anoxic zone ammonia nitrogen concentration and the aerobic zone ammonia nitrogen concentration at each historical moment in the historical data, the historical data is subjected to time series alignment processing to obtain the processed historical data, thereby ensuring the consistency and synchronization of the data.
[0108] Among them, the machine learning model is a decision tree model, which requires no less than 30 days of data for training before use, and the decision tree model has an iteration frequency of 7 days during use.
[0109] It should be noted that after obtaining the historical data of the sewage treatment system, the embodiment of the present invention can also use the water quality related parameters and blower aeration parameters in the historical data that have not been processed by time series alignment as input features, and use the effluent ammonia nitrogen concentration in the historical data that have not been processed by time series alignment as the target feature, and then perform time series alignment processing on the input features and the target features to obtain the processed input features and target features, and train the machine learning model with the processed input features and target features to obtain the trained machine learning model.
[0110] In addition to the above-mentioned sewage pool, server and sensor, the sewage treatment system described in the embodiment of the present invention may also include: a data acquisition and control module, which is connected to the sensor and the server respectively. The server obtains the blower aeration parameters and corresponding water quality-related parameters of the sewage treatment system collected by the sensor at the current moment through the data acquisition and control module, adjusts the blower aeration parameters according to the effluent ammonia nitrogen classification model, and outputs adjustment instructions to the blower through the data acquisition and control module, and the adjustment instructions carry the adjusted blower aeration parameters.
[0111] In addition, the sewage treatment system may further include: a user terminal, which is used to transmit data and instructions between the server and the data acquisition and control module, thereby realizing intelligent and precise control and improving user experience and work efficiency.

[0130] If the judgment result of S309 is no, return to S307.
[0131] If the judgment result of S307 is no, then enter S305.
