[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0023] For ease of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0024] Water quality parameters are characteristic indicators of various substances in water used to indicate the quality and changing trends of the water environment (water body), including: water turbidity, transparency, color, smell, taste, water temperature, pH value, BOD (COD), DO, trace harmful chemical element content, pesticide and its inorganic or organic compound content, E. coli count and bacterial content, etc.

[0025] Sewage treatment agent is an additive needed in the sewage treatment process, including polyacrylamide, cationic polyacrylamide, anionic polyacrylamide, nonionic, zwitterionic polyacrylamide or polyaluminum chloride.

[0026] Biological phosphorus removal refers to the activated sludge process, which involves alternating anaerobic and aerobic conditions during wastewater treatment. This allows phosphorus-accumulating bacteria, which accumulate excessive phosphates, to dominate, resulting in a higher phosphorus content in the activated sludge than in conventional activated sludge. Phosphate-accumulating bacteria in the sludge release phosphorus under anaerobic conditions and excessively absorb it under aerobic conditions. By discharging the phosphorus-rich excess sludge, the process removes more phosphorus from the wastewater than conventional activated sludge processes.

[0027] As introduced in the background technology, the existing control system of sewage treatment in the prior art has large hysteresis and there are control difficulties such as complexity and nonlinearity in adjusting the sewage treatment process with water quality and water quantity. Therefore, when water quality and water quantity fluctuate, it is difficult to adjust the biochemical system and the dosing system in a timely and effective manner. At the same time, it will cause the problem of unstable control of dissolved oxygen at the outlet of the biological pool and the release of phosphorus in the secondary sedimentation tank due to too low dissolved oxygen. In order to solve the problem of substandard sewage discharge caused by substandard sewage treatment agent dosage, the embodiments of the present application provide a method for determining the dosage of sewage treatment agent, a device for determining the dosage of sewage treatment agent, a computer-readable storage medium and an electronic device.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] In this embodiment, a method for determining the amount of sewage treatment agent running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] Figure 2 This is a flow chart of a method for determining the amount of sewage treatment agent according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0033] Step S201, obtaining the inlet water quality parameters and outlet water quality parameters of the biochemical system, where the biochemical system is used to treat sewage;

[0034] Specifically, the biochemical system is used for biochemical treatment of sewage, wherein the water quality parameters of the influent and the effluent can be real-time obtained, and the water quality parameter of the influent is the water quality parameter corresponding to the sewage entering the biochemical system, which can include turbidity, transparency, chroma, smell, taste, water temperature, pH value, BOD (COD), DO, trace harmful chemical element content, pesticide and inorganic or organic compound content, coliform bacteria count and bacteria content of the total amount of sewage at the current time; correspondingly, the water quality parameter of the effluent is the water quality parameter corresponding to the sewage after being treated by the biochemical system, which can include turbidity, transparency, chroma, smell, taste, water temperature, pH value, BOD (COD), DO, trace harmful chemical element content, pesticide and inorganic or organic compound content, coliform bacteria count and bacteria content of the total amount of sewage at the current time.

[0035] Step S202, determining whether the effluent water quality parameter meets the matched preset water quality index to obtain a first determination result.

[0036] Specifically, the preset water quality index is the water quality parameter of the effluent under ideal conditions after the sewage enters the biochemical system and is treated by the biochemical system, and therefore, the sewage treatment of the biochemical system after being treated by the biochemical system is determined by comparing the first determination result of the water quality parameter matched with the preset water quality index in the actual effluent water quality parameter.

[0037] Step S203, in the case that the first determination result is no, determining the amount of the sewage treatment agent added to the biochemical system according to the influent water quality parameter, the preset water quality index and a first preset relationship, wherein the first preset relationship is used to represent the logical relationship between the error between the influent water quality parameter and the preset water quality index and the sewage treatment agent.

[0038] Specifically, in the case that the first determination result is no, it indicates that the sewage treatment of the biochemical system is not up to standard, and therefore, the amount of the sewage treatment agent in the biochemical system needs to be determined again according to the influent water quality parameter, the preset water quality index and the first preset relationship, so that the biochemical system can treat the sewage with any influent water quality parameter and the sewage with any influent water quality parameter can reach the preset water quality index after being treated by the biochemical system. Specifically, the first preset relationship can be used to determine the amount of the sewage treatment agent according to the influent water quality parameter and the preset water quality index. Exemplarily, the first preset relationship can be represented as the influent water quality parameter minus the preset water quality index equaling the amount of the sewage treatment agent.

[0039] Through this embodiment, since the first preset relationship is expressed as the amount of sewage treatment agent obtained based on the inlet water quality parameters of the biochemical system and the preset water quality index, the above-mentioned biochemical system can first determine whether the sewage treatment of the biochemical system meets the standards based on the preset water quality index and the effluent water quality parameters of the biochemical system based on the real-time acquisition of the inlet water quality parameters of the biochemical system. Then, if it is determined that the sewage treatment of the current biochemical system does not meet the standards, the amount of sewage treatment agent that can make the sewage treatment of the biochemical system meet the standards can be directly determined based on the inlet water quality parameters and the first preset relationship. Therefore, through this application, the problem of substandard sewage treatment agent addition leading to substandard sewage discharge in the prior art is solved.

[0040] During the specific implementation process, in some optional embodiments, the inlet water quality parameters include the phosphorus content of the sewage in the biochemical system at the target moment, and the amount of sewage treatment agent to be added to the biochemical system is determined based on the inlet water quality parameters, the preset water quality index and the preset relationship, including: obtaining a first difference between the phosphorus content and the expected phosphorus content in the preset water quality index, the expected phosphorus content being the phosphorus content corresponding to the water quality index of the total effluent of the biochemical system; and determining the amount of sewage treatment agent to be added to the biochemical system based on the first difference and the first preset relationship.

[0041] The target moment corresponding to the above-mentioned influent water quality parameters can be any moment when the sewage enters the biochemical system. The total amount of sewage entering the biochemical system at the target moment can be obtained by measurement. Through this embodiment, on the basis of real-time acquisition of the influent water quality parameters of the biochemical system, the amount of sewage treatment agent required to make the sewage treatment of the biochemical system meet the standards can be determined, thereby solving the problem in the prior art that the sewage treatment agent addition does not meet the standards, resulting in substandard sewage discharge.

[0042] In some optional embodiments, the amount of sewage treatment agent to be added to the biochemical system is determined based on the first difference and the first preset relationship, including: obtaining the biological phosphorus removal amount of the biochemical system; determining the chemical phosphorus removal amount in the biochemical system based on the first difference and the second difference of the biological phosphorus removal amount; and determining the amount of sewage treatment agent based on the chemical phosphorus removal amount and the first preset relationship.

[0043] In the above embodiment, when the influent water quality parameters include the phosphorus content of the influent, since the biochemical system, in the process of treating the phosphorus content in the sewage, not only reduces the phosphorus content of the sewage by adding sewage treatment agents, but also uses biological phosphorus removal to reduce the phosphorus content in the sewage, therefore, in order to accurately obtain the dosage of the sewage treatment agent, the biological phosphorus removal amount of the biological phosphorus removal is first excluded, and then the chemical phosphorus removal amount can be calculated based on the above first difference, that is, the chemical phosphorus removal amount is the phosphorus content in the sewage that needs to be removed by the sewage treatment agent.

[0044] During the biological phosphorus removal process, the phosphorus-accumulating bacteria in the activated sludge absorb phosphorus from the wastewater and achieve efficient biological phosphorus removal by discharging phosphorus-rich excess sludge. Therefore, the amount of biological phosphorus removal is related to the amount of excess sludge, the phosphorus content in the activated sludge, and the concentration of volatile suspended matter in the excess sludge mixed liquor. Therefore, in some optional embodiments, obtaining the amount of biological phosphorus removal by the biochemical system includes: obtaining sludge parameters of the biochemical system treating wastewater at a target time, the sludge parameters including at least the amount of excess sludge, the phosphorus content in the activated sludge, and the concentration of volatile suspended matter in the excess sludge mixed liquor; and determining the amount of biological phosphorus removal based on the product of the amount of excess sludge, the phosphorus content in the activated sludge, and the concentration of volatile suspended matter in the excess sludge mixed liquor. Optionally, the sludge parameters can be obtained using a sensing device such as a sludge concentration meter.

[0045] Since the aeration parameters of the biochemical system will affect the total dissolved oxygen concentration of the sewage, and one of the nutrients necessary for the metabolism of microorganisms in the activated sludge is oxygen, excessive oxygen or lack of oxygen will cause the microorganisms to lose activity or even die, thereby affecting the amount of biological phosphorus removal. Therefore, in the above embodiment, in order to avoid excessive aeration volume causing energy waste and the death of microorganisms under excessive oxygen content, and to avoid the water quality of the effluent in the biochemical system not meeting the standards due to insufficient oxygen supply, the aeration parameters are corrected in real time. Specifically, in some optional embodiments, the step of obtaining the biological phosphorus removal amount of the biochemical system also includes: determining the expected aeration parameters of the biochemical system based on the inlet water quality parameters, the preset water quality index and the second preset relationship, the second preset relationship being used to characterize the logical relationship between the error between the inlet water quality parameters and the preset water quality index and the expected aeration parameters, the expected aeration parameters at least including the expected valve opening of the aeration regulating valve; correcting the current aeration parameters to the expected aeration parameters based on the third difference between the effluent water quality parameters and the corresponding water quality parameters in the preset water quality index, the current aeration parameters at least including the current valve opening of the aeration regulating valve, the inlet water quality parameters including the first biochemical oxygen demand, the inlet flow rate, the first ammonia nitrogen and the first dissolved oxygen, the preset water quality index including at least the second biochemical oxygen demand, the second ammonia nitrogen and the second dissolved oxygen of the sewage in the biochemical system at the target time, and the effluent water quality parameters including the effluent biochemical oxygen demand, the effluent ammonia nitrogen and the effluent dissolved oxygen. Optionally, the dissolved oxygen in the aerobic tank in the biochemical system can be controlled at 2-3 mg / L; optionally, the dissolved oxygen in the anoxic tank in the biochemical system can be controlled at below 0.5 mg / L.

[0046] In some optional embodiments, the inlet water quality parameters also include an initial redox potential, and the outlet water quality parameters also include a current redox potential. On the basis of determining the amount of sewage treatment agent to be added to the biochemical system based on the inlet water quality parameters, the preset water quality index and the first preset relationship, in order to further accurately determine the amount of sewage treatment agent added to the biochemical system, the method for determining the amount of sewage treatment agent also includes: obtaining a fourth difference between the current redox potential and the expected redox potential; and determining the amount of sewage treatment agent based on the first difference, the inlet water quality parameters, the preset water quality index and the first preset relationship.

[0047] Optionally, when the inlet water quality parameters also include the initial redox potential and the outlet water quality parameters also include the current redox potential, the step of obtaining the biological phosphorus removal amount of the biochemical system also includes: obtaining a fourth difference between the current redox potential and the expected redox potential, so as to determine whether the current aeration in the biochemical system is sufficient; and then, when it indicates insufficient aeration, correcting the current aeration parameters to the expected aeration parameters based on the fourth difference and the third difference between the outlet water quality parameters and the corresponding water quality parameters in the preset water quality index.

[0048] The embodiment of the present application also provides a device for determining the amount of sewage treatment agent. It should be noted that the device for determining the amount of sewage treatment agent in the embodiment of the present application can be used to execute the method for determining the amount of sewage treatment agent provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred embodiments, and those that have been described will not be repeated here. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0049] The following introduces the device for determining the amount of sewage treatment agent provided in the embodiment of the present application.

[0050] Figure 3 This is a structural block diagram of a device for determining the amount of sewage treatment agent according to an embodiment of the present application. Figure 3 As shown, the device includes:

[0051] An acquisition module 10 is used to obtain water quality parameters of the inlet and outlet water of a biochemical system, where the biochemical system is used to treat sewage;

[0052] Specifically, the biochemical system is used to perform biochemical treatment on sewage, wherein the above-mentioned inlet water quality parameters and outlet water quality parameters can both be water quality parameters obtained in real time. Furthermore, the above-mentioned inlet water quality parameters are the water quality parameters corresponding to the sewage when entering the above-mentioned biochemical system, and the water quality parameters may include the turbidity, transparency, chromaticity, odor, taste, water temperature, pH value, BOD (COD), DO, trace harmful chemical element content, pesticide and its inorganic or organic compound content, E. coli count and bacterial content, etc. corresponding to the total amount of sewage at the current moment; accordingly, the above-mentioned outlet water quality parameters are the water quality parameters corresponding to the sewage after treatment by the above-mentioned biochemical system, and the water quality parameters may include the turbidity, transparency, chromaticity, odor, taste, water temperature, pH value, BOD (COD), DO, trace harmful chemical element content, pesticide and its inorganic or organic compound content, E. coli count and bacterial content, etc. corresponding to the total amount of sewage at the current moment.

[0053] The judgment module 20 is used to judge whether the water quality parameters of the outlet water meet the matching preset water quality indicators and obtain a first judgment result;

[0054] Specifically, the above-mentioned preset water quality indicators are the water quality parameters of the effluent under ideal conditions after the sewage enters the biochemical system and is treated by the biochemical system. Therefore, after the influent of the biochemical system is treated by the biochemical system, the first judgment result obtained by comparing the water quality parameters of the actual effluent with the water quality parameters that match the preset water quality indicators is used to determine whether the sewage treatment of the biochemical system meets the standards.

[0055] The determination module 30 is used to determine the amount of sewage treatment agent to be added to the biochemical system based on the influent water quality parameters, the preset water quality index and the first preset relationship when the first judgment result is no. The first preset relationship is used to characterize the error between the influent water quality parameters and the preset water quality index and the logical relationship between the sewage treatment agent.

[0056] Specifically, if the first judgment result is negative, it indicates that the sewage treatment of the biochemical system does not meet the standards. Therefore, it is necessary to re-determine the amount of sewage treatment agent in the biochemical system based on the influent water quality parameters, the preset water quality index, and the first preset relationship, so that the biochemical system can treat sewage with any influent water quality parameters and ensure that the sewage with any influent water quality parameters can meet the preset water quality index after being treated by the biochemical system. Specifically, the first preset relationship can be used to determine the amount of sewage treatment agent based on the influent water quality parameters and the preset water quality index. Exemplarily, the first preset relationship can be expressed as influent until the parameter minus the preset water quality index equals the amount of sewage treatment agent.

[0057] Through this embodiment, since the first preset relationship is expressed as the amount of sewage treatment agent obtained based on the inlet water quality parameters of the biochemical system and the preset water quality index, the above-mentioned biochemical system can first determine whether the sewage treatment of the biochemical system meets the standards based on the preset water quality index and the effluent water quality parameters of the biochemical system based on the real-time acquisition of the inlet water quality parameters of the biochemical system. Then, if it is determined that the sewage treatment of the current biochemical system does not meet the standards, the amount of sewage treatment agent that can make the sewage treatment of the biochemical system meet the standards can be directly determined based on the inlet water quality parameters and the first preset relationship. Therefore, through this application, the problem of substandard sewage treatment agent addition leading to substandard sewage discharge in the prior art is solved.

[0058] During the specific implementation process, in some optional embodiments, the determination module includes: a first processing module, used to obtain a first difference between the phosphorus content and the expected phosphorus content in the preset water quality index, where the expected phosphorus content is the phosphorus content corresponding to the water quality index of the total effluent volume of the biochemical system; a second processing module, used to determine the amount of sewage treatment agent to be added to the biochemical system based on the first difference and the first preset relationship.

[0059] The target moment corresponding to the above-mentioned influent water quality parameters can be any moment when the sewage enters the biochemical system. The total amount of sewage entering the biochemical system at the target moment can be obtained by measurement. Through this embodiment, on the basis of real-time acquisition of the influent water quality parameters of the biochemical system, the amount of sewage treatment agent required to make the sewage treatment of the biochemical system meet the standards can be determined, thereby solving the problem in the prior art that the sewage treatment agent addition does not meet the standards, resulting in substandard sewage discharge.

[0060] In some optional embodiments, the second processing module includes: a first processing submodule, used to obtain the biological phosphorus removal amount of the biochemical system; a second processing submodule, used to determine the chemical phosphorus removal amount in the biochemical system based on the first difference and the second difference of the biological phosphorus removal amount; and a third processing submodule, used to determine the amount of sewage treatment agent based on the chemical phosphorus removal amount and the first preset relationship.

[0061] In the above embodiment, when the influent water quality parameters include the phosphorus content of the influent, since the biochemical system, in the process of treating the phosphorus content in the sewage, not only reduces the phosphorus content of the sewage by adding sewage treatment agents, but also uses biological phosphorus removal to reduce the phosphorus content in the sewage, therefore, in order to accurately obtain the dosage of the sewage treatment agent, the biological phosphorus removal amount of the biological phosphorus removal is first excluded, and then the chemical phosphorus removal amount can be calculated based on the above first difference, that is, the chemical phosphorus removal amount is the phosphorus content in the sewage that needs to be removed by the sewage treatment agent.

[0062] Since the polyphosphate bacteria in the activated sludge will absorb phosphorus in the wastewater during the biological phosphorus removal process and achieve the purpose of efficient biological phosphorus removal by discharging phosphorus-rich residual sludge, the amount of biological phosphorus removal is related to the amount of residual sludge, the phosphorus content in the activated sludge and the concentration of volatile suspended matter in the residual sludge mixed liquor. Therefore, in some optional embodiments, the first processing submodule includes: a fourth processing submodule, which is used to obtain sludge parameters for the biochemical system to treat sewage at the target time, and the sludge parameters include at least the amount of residual sludge, the phosphorus content in the activated sludge and the concentration of volatile suspended matter in the residual sludge mixed liquor; a fifth processing submodule, which is used to determine the amount of biological phosphorus removal based on the product of the amount of residual sludge, the phosphorus content in the activated sludge and the concentration of volatile suspended matter in the residual sludge mixed liquor.

[0063] Since the aeration parameters of the biochemical system will affect the total dissolved oxygen concentration of the sewage, and one of the nutrients necessary for the metabolism of microorganisms in the activated sludge is oxygen, anaerobic conditions will cause aerobic microorganisms to lose their activity or even die, thereby affecting the amount of biological phosphorus removal. Therefore, in the above embodiment, in order to improve the biological phosphorus removal effect in the biochemical system, the aeration parameters are corrected in real time. Specifically, in some optional embodiments, the first processing submodule also includes: a sixth processing submodule, used to determine the expected aeration parameters of the biochemical system based on the inlet water quality parameters, the preset water quality index and the second preset relationship, the second preset relationship is used to characterize the logical relationship between the error between the inlet water quality parameters and the preset water quality index and the expected aeration parameters, and the expected aeration parameters include at least the expected valve opening of the aeration regulating valve; a seventh processing submodule, used to correct the current aeration parameters to the expected aeration parameters based on the third difference between the outlet water quality parameters and the corresponding water quality parameters in the preset water quality index, the current aeration parameters include at least the current valve opening of the aeration regulating valve, the inlet water quality parameters include the first biochemical oxygen demand, the inlet flow rate, the first ammonia nitrogen and the first dissolved oxygen, the preset water quality indicators include at least the second biochemical oxygen demand, the second ammonia nitrogen and the second dissolved oxygen of the sewage in the biochemical system at the target time, and the outlet water quality parameters include the outlet biochemical oxygen demand, the outlet ammonia nitrogen and the outlet dissolved oxygen.

On the basis of determining the amount of sewage treatment agent to be added to the biochemical system based on the inlet water quality parameters, the preset water quality index and the first preset relationship, in order to further accurately determine the amount of sewage treatment agent added to the biochemical system, the sewage treatment agent amount determination device also includes: a third processing module for obtaining a fourth difference between the current redox potential and the expected redox potential; a fourth processing module for determining the amount of sewage treatment agent based on the first difference, the inlet water quality parameters, the preset water quality index and the first preset relationship.

[0065] Optionally, when the inlet water quality parameters also include the initial redox potential and the outlet water quality parameters also include the current redox potential, the first processing submodule also includes: an eighth processing submodule, used to obtain a fourth difference between the current redox potential and the expected redox potential, so as to determine whether the current aeration in the biochemical system is sufficient; and a ninth processing submodule, which, when insufficient aeration is indicated, corrects the current aeration parameters to the expected aeration parameters based on the fourth difference and the third difference between the outlet water quality parameters and the corresponding water quality parameters in the preset water quality index.

The acquisition module, judgment module, and determination module are all stored as program units in the memory. The processor executes the program units stored in the memory to implement the corresponding functions. The modules are all located in the same processor; alternatively, the modules can be located in different processors in any combination.

[0067] The processor includes a core, which retrieves corresponding program units from memory. One or more cores can be configured, and kernel parameters are adjusted to determine the dosage of a sewage treatment agent that meets the wastewater treatment standards of the biochemical system.

[0069] An embodiment of the present invention provides a computer-readable storage medium, which includes a stored program. When the program runs, the device where the computer-readable storage medium is located is controlled to execute a method for determining the amount of a sewage treatment agent.

[0070] Specifically, the method for determining the amount of sewage treatment agent includes:

[0071] Step S201, obtaining the inlet water quality parameters and outlet water quality parameters of the biochemical system, where the biochemical system is used to treat sewage;

[0072] Specifically, the biochemical system is used to perform biochemical treatment on sewage, wherein the above-mentioned inlet water quality parameters and outlet water quality parameters can both be water quality parameters obtained in real time. Furthermore, the above-mentioned inlet water quality parameters are the water quality parameters corresponding to the sewage when entering the above-mentioned biochemical system, and the water quality parameters may include the turbidity, transparency, chromaticity, odor, taste, water temperature, pH value, BOD (COD), DO, trace harmful chemical element content, pesticide and its inorganic or organic compound content, E. coli count and bacterial content, etc. corresponding to the total amount of sewage at the current moment; accordingly, the above-mentioned outlet water quality parameters are the water quality parameters corresponding to the sewage after treatment by the above-mentioned biochemical system, and the water quality parameters may include the turbidity, transparency, chromaticity, odor, taste, water temperature, pH value, BOD (COD), DO, trace harmful chemical element content, pesticide and its inorganic or organic compound content, E. coli count and bacterial content, etc. corresponding to the total amount of sewage at the current moment.

[0076] Specifically, if the first judgment result is negative, it indicates that the sewage treatment of the biochemical system does not meet the standards. Therefore, it is necessary to re-determine the amount of sewage treatment agent in the biochemical system based on the influent water quality parameters, the preset water quality index, and the first preset relationship, so that the biochemical system can treat sewage with any influent water quality parameters and ensure that the sewage with any influent water quality parameters can meet the preset water quality index after being treated by the biochemical system. Specifically, the first preset relationship can be used to determine the amount of sewage treatment agent based on the influent water quality parameters and the preset water quality index.
