Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an intelligent dosing method and system based on distributed wastewater treatment. Background Technology

[0002] In today's distributed wastewater treatment fields, such as decentralized wastewater treatment plants in villages and towns, zoned treatment units in industrial parks, and greywater reuse systems in buildings, the precision of chemical dosing and the control of operating conditions are key to ensuring stable effluent quality, reducing operation and maintenance costs, and realizing the recycling of water resources.

[0003] Currently, most wastewater treatment plants use a feedforward combined with feedback control structure for their chemical dosing control systems. The feedback controller mainly uses the traditional PID control algorithm. When the wastewater quality and quantity change, the feedforward controller is used to reduce or eliminate the interference, and the feedback controller is used to correct the deviation. The feedforward controller mainly uses flow proportional control, which controls the chemical dosing to increase proportionally according to the change in wastewater flow. The impact of water quality changes is mainly corrected by the feedback controller.

[0004] Regarding the aforementioned technologies, in practice, the inability to effectively integrate data from multiple sources leads to a lag in wastewater treatment, resulting in delays and an inability to treat wastewater in a timely manner. There is still room for improvement in the real-time performance of wastewater treatment using chemicals. Summary of the Invention

[0005] To improve the real-time performance and reliability of wastewater treatment, this invention provides an intelligent dosing method and system based on distributed wastewater treatment.

[0006] In a first aspect, the present invention provides an intelligent dosing method based on distributed wastewater treatment, employing the following technical solution:

[0007] A smart dosing method based on distributed wastewater treatment includes:

[0008] Step 1: In response to the preset drainage completion signal, obtain the sewage tank number;

[0009] Step 2: Extract the type and flow rate of wastewater to be treated by the wastewater tank number;

[0010] Step 3: Search for the corresponding reagent type and dosage in the preset reagent database based on the wastewater type and flow rate;

[0011] Step 4: When a preset wastewater inflow signal is received, acquire the wastewater parameters;

[0012] Step 5: Determine the required types and quantities of chemicals based on wastewater parameters;

[0013] Step 6: Determine the type of drug to be used from the drug categories based on the types of drug requirements;

[0014] Step 7: Determine the dosage of the drug based on the required dosage, and formulate a dosing plan by combining the types of drugs to be used, and then implement it;

[0015] Step 8: After the dosing plan is completed, re-collect wastewater parameters and define them as purification parameters;

[0016] Step 9: If the purification parameters fall within the preset standard parameter range, define the purification parameters corresponding to the wastewater tank number as reclaimed water parameters and output them.

[0017] By adopting the above technical solution, the type and flow rate of sewage are obtained through the sewage tank number, and the type and dosage of the chemical agent are obtained accordingly. When sewage is detected entering, the final type and dosage of the chemical agent are determined by combining the sewage parameters with the type and dosage of the chemical agent. Then, the dosing plan is obtained and executed. Then, the parameters of the reclaimed water are collected again to avoid incomplete sewage treatment in a single treatment and improve the real-time performance and reliability of sewage treatment.

[0018] Optional, also includes:

[0019] Step 10: If the purification parameters do not fall within the standard parameter range, analyze the type and amount of reagent to be supplemented based on the purification parameters;

[0020] Step 11: Integrate the types and amounts of medications to obtain a medication replenishment plan and execute it;

[0021] Step 12: Once the purification parameters fall within the standard parameter range or the dosing replenishment plan has been completed, obtain the remaining types and quantities of chemicals.

[0022] Step 13: Search for the corresponding drug application pool number group in the drug database based on the remaining types of drugs. The drug application pool number group does not include the sewage pool number.

[0023] Step 14: If the medicine pool number group exists, disassemble the medicine pool number group to obtain multiple medicine pool numbers;

[0024] Step 15: Extract the wastewater treatment type group corresponding to the treatment tank number;

[0025] Step 16: Determine the medication group based on the type of drug;

[0026] Step 17: Compare the wastewater treatment agent group with the treatment agent group to obtain similarity ratio values;

[0027] Step 18: If the similarity ratio reaches the preset fusion ratio threshold, calculate and output the amount of purified wastewater based on the remaining amount of reagent;

[0028] Step 19: If the similarity ratio value does not reach the fusion ratio threshold, determine the corresponding wastewater dosage by using the dosage tank number;

[0029] Step 20: Calculate and output the amount of chemicals to be added to the chemical tank based on the required amount of chemicals for the wastewater and the remaining amount of chemicals.

[0030] By adopting the above technical solution, in cases where purification parameters fail to meet standards, the problem of incomplete treatment in a single treatment is avoided by analyzing the types and amounts of reagents to be added and implementing a supplementary plan. After treatment, suitable reagent tanks are found based on the remaining reagent types. The remaining reagents are then allocated according to the similarity ratio comparison. When the similarity ratio meets the standard, the amount of wastewater that can be purified is calculated to maximize the value of the reagents. When the standard is not met, the amount of reagents to be added to the reagent tank is accurately calculated to avoid reagent waste and improve the intelligence, reagent utilization rate and operation economy of distributed wastewater treatment.

[0031] Optionally, methods for calculating and outputting the replenishment amount of chemicals in the chemical tank based on the required amount of chemicals for wastewater and the remaining amount of chemicals include:

[0032] Step 200: Calculate the percentage of remaining reagent based on the remaining reagent amount and the required reagent amount for wastewater;

[0033] Step 201: If the remaining amount of medicine reaches the preset cost-effectiveness threshold, calculate and output the amount of medicine to be added to the medicine tank based on the required amount of medicine for sewage and the remaining amount of medicine;

[0034] Step 202: If the remaining dosage does not reach the cost-effectiveness threshold, the required dosage for wastewater is output as the dosage for replenishing the dosing tank.

[0035] Step 203: Integrate the remaining types and quantities of drugs to form waste drug data and output it.

[0036] By adopting the above technical solution, the remaining chemical quantity ratio is calculated based on the remaining chemical quantity and the chemical quantity required for sewage. Combined with a preset cost-effectiveness threshold, two replenishment calculation logics are distinguished. When the remaining chemical quantity ratio meets the standard, the replenishment quantity of the chemical tank is calculated based on the actual remaining chemical quantity, making full use of existing chemical resources. When the standard is not met, the sewage demand chemical quantity is directly output and the remaining chemical is integrated to form waste chemical data, providing accurate basis for chemical procurement and disposal, avoiding chemical waste caused by inefficient use, and improving the resource allocation accuracy and operation management level of the distributed sewage treatment system.

[0037] Optionally, methods for integrating and outputting waste drug data based on the remaining types and quantities of drugs include:

[0038] Step 2030: If the remaining dosage does not reach the cost-effectiveness threshold, obtain the reclaimed water demand information;

[0039] Step 2031: Extract the range of water quality parameters from the reclaimed water demand information;

[0040] Step 2032: Calculate the purification over-parameters using the reclaimed water parameters and the remaining amount of reagents;

[0041] Step 2033: If the purification over-parameter falls within the water quality parameter range, a reagent ignoring scheme is formulated based on the remaining reagent quantity and remaining reagent types and is executed;

[0042] Step 2034: If the purification over-parameter does not fall within the water quality parameter range, integrate the remaining types and quantities of reagents to form waste reagent data and output it.

[0043] By adopting the above technical solution, for situations where the remaining amount of chemicals does not reach the cost-effectiveness threshold, the availability of remaining chemicals is assessed by combining the reclaimed water quality requirements and purification over-parameters. When chemicals are available, a chemical ignoring scheme is implemented, and when chemicals are unavailable, waste chemical data is generated. This improves the utilization rate of chemical resources and reduces material losses and environmental disposal costs in wastewater treatment.

[0044] Optionally, methods for finding the corresponding drug type and dosage include:

[0045] Step 30: Obtain the actual time period;

[0046] Step 31: Search for the corresponding wastewater situation in the preset historical database based on the actual time period;

[0047] Step 32: Analyze the wastewater situation to obtain historical wastewater types, historical types of chemicals, and historical dosages;

[0048] Step 33: Search the historical wastewater treatment agent types in the agent database based on the historical wastewater types;

[0049] Step 34: Determine the actual types of chemicals based on historical wastewater treatment methods and the historical types of chemicals used;

[0050] Step 35: Sort the historical medication dosage according to the preset time arrangement rules to obtain the medication dosage ranking;

[0051] Step 36: Analyze historical changes in medication usage by ranking medication dosages and combining them with historical medication dosages;

[0052] Step 37: Analyze future medication dosage based on historical changes in medication use and the actual types of medications used;

[0053] Step 38: Define the actual drug type as the drug type and the future dosage as the drug dosage.

[0054] By adopting the above technical solution, and combining historical sewage and drug usage data with actual time periods, the actual types of drugs are determined through comparison and screening. By analyzing the ranking and changes in historical drug usage, the future drug usage can be estimated. This avoids the problem of not being able to determine the types of drugs and approximate dosages due to the inability to predict the types of sewage in the next instance. This improves the scientific nature of determining the types and dosages of drugs and ensures the foresight and rationality of the dosing plan.

[0055] Optionally, methods for developing a dosing regimen include:

[0056] Step 70: Obtain the drug storage quantity corresponding to the drug type;

[0057] Step 71: If the required amount of the agent is greater than the available amount, analyze the agent's effect based on the type of wastewater and the type of agent.

[0058] Step 72: If the effect of the medicine is a preset ignore effect, define the medicine type as an ignore type;

[0059] Step 73: After screening the drug types, perform step 6 to obtain the types to be used and define them as abundant types;

[0060] Step 74: Obtain the corresponding amount of surplus medication based on the type of surplus, and combine the types of surplus, the types to be ignored, and their corresponding drug storage quantities to form an ignoring scheme;

[0061] Step 75: If the effect of the drug is not negligible, generate and output a corresponding drug shortage signal based on the drug type and drug storage quantity;

[0062] Step 76: If the required amount of medicine is less than the available amount of medicine, proceed to steps 6 and 7 to form a dosing plan.

[0063] By adopting the above technical solution, the dosing strategy is dynamically adjusted based on the comparison between the storage and demand of the reagents. When the demand for reagents is greater than the storage, the corresponding reagent is listed as an ignored type based on the reagent effect. Then, the abundant types are selected to form an ignored scheme. If the reagent effect is not negligible, a shortage signal is output. When the demand is less than the storage, a dosing scheme is directly generated. This avoids the problem of sewage treatment interruption caused by insufficient reagent inventory and improves the flexibility and feasibility of the dosing scheme.

[0064] Optional, also includes:

[0065] Step 750: When a drug shortage signal is received, execute steps 1 to 3 to obtain the drug type and define it as a future type;

[0066] Step 751: Repeat step 70 to obtain multiple drug storage quantities and compare them with the corresponding drug demand quantities;

[0067] Step 752: If the required amount of chemicals is less than the available amount of chemicals, find other treatment tank numbers based on the wastewater tank number and the future type.

[0068] Step 753: Replace the wastewater tank number with the other treatment tank number to obtain the updated treatment tank number and output it.

[0069] By adopting the above technical solution, when a drug shortage signal is received, the drug type screening process is re-executed to determine the future type. After multiple rounds of comparison between drug storage and demand, when the drug use conditions are met, the updated treatment tank number is output based on the sewage tank number and the future type. This avoids the sewage treatment process from being stopped due to a single tank's lack of drugs, and improves the system's fault tolerance and intelligent scheduling level.

[0070] Alternatively, methods for developing a dosing regimen may also include:

[0071] Step 77: Search for the corresponding pollutant type in the preset pollution database based on the type of reagent and the type of wastewater;

[0072] Step 78: If the type of pollutant is not available, determine the dosing plan based on the type and dosage of the drug used;

[0073] Step 79: If pollutant types exist, search for the corresponding pollution removal solution in the preset pollution removal database based on the pollutant type;

[0074] Step 80: When a decontamination plan exists, a final plan is formed based on the decontamination plan and the chemical dosing plan and then executed.

[0075] By adopting the above technical solution, the pollutant type is accurately matched with the type of chemical agent and the type of wastewater. When there is no corresponding pollutant, the dosing plan is directly generated based on the type and dosage of the chemical agent used. When there is a pollutant, the matching pollution removal plan is retrieved and integrated with the dosing plan to form the final plan. This avoids the drawback of single chemical treatment being unable to deal with specific pollutants and improves the targeting and deep purification effect of wastewater treatment.

[0076] Optionally, it also includes a solution for when a decontamination solution is unavailable, the method comprising:

[0077] Step 81: Determine the pollutant situation based on the type of pollutant;

[0078] Step 82: If the pollutant situation is the preset object situation, find the corresponding temporary storage tank number according to the sewage tank number;

[0079] Step 83: Determine and implement a water transfer plan based on the type of pollutant, the wastewater tank number, and the temporary storage tank number;

[0080] Step 84: If the pollutant situation is the preset water body situation, determine the salvage plan according to the sewage tank number and the type of pollutant and execute it.

[0081] By adopting the above technical solution, for scenarios without a corresponding pollution removal solution, the system determines the object or water condition where the pollutant is located based on the type of pollutant, and then executes a water transfer or dredging plan accordingly. When the pollutant is an object, it is linked to a temporary storage tank to complete the separation and transfer of clean water. When the pollutant is a water condition, it is targeted to dredge and remove the pollutant, thus avoiding the residue of specific pollutants that could lead to substandard reclaimed water quality and improving the adaptability and reliability of the system.

[0082] Secondly, this invention provides an intelligent dosing system based on distributed wastewater treatment, employing the following technical solution:

[0083] An intelligent dosing system based on distributed wastewater treatment includes:

[0084] The acquisition module is used to acquire the wastewater tank number, wastewater parameters, reclaimed water demand information, actual time period, and reagent storage quantity.

[0085] A memory for storing the program of a control method for an intelligent dosing method based on distributed wastewater treatment, as described above;

[0086] The processor loads and executes programs from memory.

[0087] By adopting the above technical solution, the core data such as sewage tank number is collected uniformly by the acquisition module, and the intelligent dosing method program is stably stored by the memory. Then, the processor loads and executes the program to integrate the aforementioned functions such as dynamic dosing adjustment, emergency scheduling for insufficient dosing, refined management of remaining dosing agents, and targeted treatment of pollutants. This realizes the automated and standardized operation of the distributed sewage treatment intelligent dosing process, and improves the overall intelligent management level and sewage treatment stability of the system.

[0088] In summary, the present invention has at least one of the following beneficial technical effects:

[0089] 1. By obtaining the wastewater type and flow rate through the wastewater tank number, the type and dosage of the chemical agent can be determined. When wastewater is detected entering, the final type and dosage of the chemical agent are determined by combining the wastewater parameters with the chemical agent type and dosage. Then, the dosing plan is obtained and executed. Then, the parameters of the reclaimed water are collected again, so that the relevant chemicals can be prepared before the wastewater arrives at the treatment site, avoiding the inability to treat the wastewater in the first place upon arrival, thus improving the timeliness and reliability of wastewater treatment.

[0090] 2. By analyzing the different types of sewage tanks, the use of excess chemicals can be determined, thus better avoiding waste and improving the utilization rate of chemicals and the reliability of sewage treatment.

[0091] 3. By combining historical data on the types of wastewater in the current time period, it is possible to predict the types of wastewater in the future, avoiding the situation of blindly determining the types of reagents, and improving the timeliness and accuracy of wastewater treatment. Attached Figure Description

[0092] Figure 1 This is a flowchart of an intelligent dosing method based on distributed wastewater treatment, according to an embodiment of this application. Detailed Implementation

[0093] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0094] This invention discloses an intelligent dosing method based on distributed wastewater treatment. (Refer to...) Figure 1 A smart dosing method based on distributed wastewater treatment includes:

[0095] Step 1: In response to the preset drainage completion signal, obtain the sewage tank number.

[0096] The "Drainage Completed" signal is a status trigger signal generated when the wastewater treatment tank has completed the purification treatment of the current batch of wastewater and discharged all the water in the tank into the designated reuse or discharge network, with no water remaining in the tank. The system responds by detecting the water in the wastewater treatment tank using devices (water level monitoring devices, cameras, etc.). When there is no residual water in the wastewater treatment tank, the "Drainage Completed" signal is automatically triggered.

[0097] The wastewater tank number refers to the unique identification code assigned to each wastewater treatment tank. The wastewater tank number is obtained by having professionals in the field pre-assign unique numbers to all wastewater treatment tanks included in the system and inputting them into the system. When the system receives a discharge completion signal, it automatically retrieves the number of the wastewater tank that issued the signal.

[0098] Step 2: Extract the type and flow rate of wastewater to be treated by the wastewater tank number.

[0099] Wastewater type refers to the category of wastewater classified according to its source and pollutant composition. The wastewater type is obtained by the system recording the source and pollutant composition information of each batch of wastewater treated by the wastewater tank in real time, generating a comprehensive wastewater type for that wastewater tank, and combining this with the wastewater type pre-input by personnel in the field to form the final wastewater type treated by the wastewater tank. Wastewater flow rate refers to the volume of wastewater entering the wastewater tank per unit time. The wastewater flow rate is extracted by the system recording the influent flow rate data of each batch of wastewater treated by the wastewater tank in real time, generating a comprehensive wastewater flow rate statistical value for that wastewater tank, and combining this with the design wastewater flow rate pre-input by personnel in the field to form the final wastewater flow rate.

[0100] Step 3: Search for the corresponding reagent type and dosage in the preset reagent database based on the wastewater type and flow rate.

[0101] The term "chemical agent type" refers to the specific category of wastewater treatment agents capable of degrading, separating, or transforming pollutants, tailored to different wastewater sources, pollutant compositions, and flow rates. The method for finding chemical agent types involves the system searching its database for the corresponding agent based on the wastewater type. This database stores a mapping between wastewater types and chemical agent types. The chemical agent types for each type of wastewater are determined in advance by professionals in the field through experiments with various wastewater types and then input into the system. When the system receives a wastewater type, it automatically searches the database for the corresponding chemical agent. The term "chemical dosage" refers to the amount of wastewater treatment agent added to achieve the desired pollutant removal effect and ensure effluent compliance for a specific wastewater type and flow rate. The method for finding the dosage of the reagent here is that the system searches the reagent database for the corresponding reagent dosage based on the sewage flow rate. The reagent database stores the mapping relationship between sewage flow rate and reagent dosage. The reagent dosage for the corresponding flow rate is obtained in advance by professionals in this field through treatment experiments of different sewage flow rates and then input into the system. When the system receives the sewage flow rate, it automatically searches the reagent database for the corresponding reagent dosage.

[0102] Step 4: When a preset wastewater inflow signal is received, acquire the wastewater parameters.

[0103] The wastewater inflow signal refers to the trigger signal that wastewater has been transported into the wastewater treatment tank. The wastewater inflow signal is received by installing a pipeline flow sensor or infrared level sensor in the wastewater tank's inlet pipe. The sensor monitors the fluid flow in the inlet pipe in real time, and when the sensor detects continuous wastewater flow in the pipe, it immediately sends an electrical signal to the system control center.

[0104] Wastewater parameters refer to the characteristics of wastewater quality and operating conditions entering the wastewater treatment plant. Here, wastewater parameters are obtained by deploying multi-parameter online water quality monitoring instruments at the wastewater inlet of the plant. These instruments collect real-time data on water quality indicators such as COD, NH3-N, TP, pH, and SS, and then integrate this data to form wastewater parameters. For example, a chemical oxygen demand (COD) sensor obtains data on the degree of oxidizable organic pollution in the wastewater, and an ammonia nitrogen (NH3-N) sensor obtains data on the content of ammonia nitrogen in the wastewater.

[0105] When a wastewater inflow signal is received, it indicates that new wastewater has entered the wastewater treatment tank, and therefore wastewater parameters are obtained.

[0106] Step 5: Determine the required types and quantities of chemicals based on the wastewater parameters.

[0107] The required reagent type refers to the specific category of wastewater treatment reagents needed to achieve the required wastewater purification standards. The reagent type is determined by professionals in the field who pre-determine the corresponding reagent type based on different wastewater parameters and input it into the system. When the system collects wastewater parameters, it automatically retrieves and matches the corresponding reagent type. The required reagent quantity refers to the amount of wastewater treatment reagent needed to achieve the desired purification effect. The required reagent quantity is determined by professionals in the field through multiple experiments to obtain the required quantity of each reagent for different wastewater parameters and inputting it into the system's algorithm or model (e.g., PID control algorithm, multiple linear regression model, etc.). When the system receives wastewater parameters, it automatically calculates the required reagent quantity based on the wastewater parameters in the algorithm or model.

[0108] Step 6: Determine the type of drug to be used from the drug categories based on the types of drug requirements.

[0109] The "use type" refers to selecting the wastewater treatment agent that overlaps with the agent requirements corresponding to the real-time wastewater parameters from the agent database. This process ultimately determines the specific category of wastewater treatment agent to be added to the wastewater treatment tank. The method for determining the use type involves the system comparing and matching the found agent types with the agent requirement types, and then selecting the intersection of the two sets of data to obtain the use type.

[0110] Step 7: Determine the dosage of the drug based on the required dosage, and combine this with the type of drug to form a dosing plan and execute it.

[0111] The dosage of wastewater treatment chemicals used refers to selecting the dosage from a chemical database that matches the real-time wastewater parameters, ultimately determining the specific amount of wastewater treatment chemicals to be added to the wastewater treatment tank. The method for determining the dosage is as follows: the system compares the found dosage with the required dosage, while simultaneously introducing an environmental factor correction coefficient to dynamically calibrate the baseline dosage. The system then selects the compatible portions of the two sets of data and combines the correction results to arrive at the corrected dosage. These environmental factors are collected by sensors in the relevant environment of the wastewater treatment tank, such as: a water temperature sensor to collect real-time wastewater temperature data, a pH sensor to collect wastewater acidity / alkalinity data, and a dissolved oxygen (DO) sensor to collect dissolved oxygen content data in the wastewater.

[0112] A dosing plan refers to a standardized process that combines the final determined types and quantities of chemicals to be used, specifying key execution information such as the order of dosing, acceleration rate, timing, and location. The dosing plan is generated by the system associating and binding the determined types and quantities of chemicals to be used, and determining key information such as the dosing order, acceleration rate, timing, and location. The execution of the dosing plan involves the system sending the generated standardized dosing plan to the execution terminal of the dosing system. This controls the dosing pumps to start according to the dosing order, accurately meter the chemicals according to the set acceleration rate, and simultaneously uses a time control module to match the dosing time, combined with the opening and closing commands of pipeline valves, to deliver the chemicals to the designated dosing location to complete the execution. The dosing scheme here simultaneously collects real-time operating data from multiple dimensions and dynamically adjusts the dosing rate or interval. Specific data collection dimensions include wastewater mixing uniformity (collected by stirring power sensor and turbidity sensor), chemical reaction process (collected by oxidation-reduction potential (ORP) sensor and real-time water quality monitor), and equipment operating status (collected by dosing pump pressure sensor and flow meter). Based on the cross-validation results of multi-dimensional operating data, the system corrects the dosing rate or adds dosing intervals in real time to ensure that the chemicals react fully with the wastewater and improve the treatment effect.

[0113] Step 8: After the dosing program is completed, re-collect wastewater parameters and define them as purification parameters.

[0114] Purification parameters refer to the water quality and operating condition indicators that the system re-collects from the wastewater in the tank after the chemical dosing program has been completed and the wastewater has undergone chemical reaction treatment. The method for obtaining purification parameters here is the same as the method for obtaining wastewater parameters described in step 4, and will not be repeated here.

[0115] Once the dosing procedure is completed, it indicates that the wastewater tank has been treated. However, to avoid any untreated residues, wastewater parameters are collected again and defined as purification parameters.

[0116] Step 9: If the purification parameters fall within the preset standard parameter range, define the purification parameters corresponding to the wastewater tank number as reclaimed water parameters and output them.

[0117] The standard parameter range refers to the compliance threshold range of various water quality indicators (such as COD, NH3-N, TP, pH, SS, etc.) used to determine whether wastewater, after purification treatment, meets the requirements for reuse or discharge. The method for obtaining this standard parameter range is determined by professionals in this field based on actual needs and then input into the system.

[0118] Reclaimed water parameters refer to the compliant water quality indicators that are linked to the corresponding wastewater tank number and meet the conditions for reuse or discharge. Here, the reclaimed water output method involves the system automatically associating and integrating the parameters with information such as the corresponding wastewater tank number, treatment batch, and treatment time after defining the reclaimed water parameters, and then outputting this information to the monitoring terminal for reclaimed water reuse or discharge for visual display.

[0119] If the purification parameters fall within the standard parameter range, it indicates that the wastewater has reached the level of reclaimed water. At this time, the purification parameters corresponding to the wastewater tank number are defined as reclaimed water parameters and output.

[0120] This also includes:

[0121] Step 10: If the purification parameters do not fall within the standard parameter range, analyze the type and amount of reagent to be supplemented based on the purification parameters.

[0122] The type of chemical supplementation refers to the specific category of wastewater treatment chemicals that need to be added to address water quality indicators that do not meet standards. The dosage of chemical supplementation refers to the specific amount of additional chemicals to be added, calculated based on the degree of deviation from the standards, for water quality indicators that do not meet standards. The analysis method for the type and dosage of chemical supplementation here is the same as the method for obtaining the type of chemical based on wastewater parameters described in step 5, and will not be repeated here.

[0123] If the purification parameters do not fall within the standard parameter range, it indicates that the wastewater has not been properly treated and needs to be replenished with chemicals for further treatment. Therefore, the type and amount of chemicals to be replenished should be analyzed based on the purification parameters.

[0124] Step 11: Integrate the types and amounts of medications to obtain a medication replenishment plan and execute it.

[0125] A chemical replenishment plan is a specialized plan designed to address situations where purification parameters fail to meet standards. It integrates the types and quantities of additional chemicals to be replenished, specifying key execution information such as the order, acceleration rate, timing, and location of the additional chemicals. This replenishment plan is generated by the system associating and binding the determined types and quantities of chemicals to be replenished, and defining key information such as the order, acceleration rate, timing, and location. The system then integrates these elements to generate a standardized replenishment plan. The system executes this plan by sending it to the dosing system's execution terminal. This terminal controls the dosing pumps to start according to the order of the additional chemicals, precisely metering and adding the replenished chemicals at the set acceleration rate. Simultaneously, the time control module matches the timing of the addition, and the system uses valve opening and closing commands to deliver the replenished chemicals to the designated location to complete the process.

[0126] Step 12: Once the purification parameters fall within the standard parameter range or the dosing replenishment plan has been completed, obtain the remaining types and quantities of the reagents.

[0127] Residual chemical types refer to the specific categories of wastewater treatment chemicals that have not fully participated in the purification reaction and remain in the wastewater tank. This is obtained by the system identifying the chemical types corresponding to each chemical dosing pipe around the wastewater tank, and combining this with the execution records of the dosing and replenishment plans to filter out the chemical types corresponding to pipes where chemicals still remain. Residual chemical quantity refers to the specific amount of wastewater treatment chemicals that have not fully participated in the purification reaction and remain in the wastewater tank. This is obtained by the system using chemical metering sensors installed on each chemical dosing pipe to collect the amount of chemicals remaining in each pipe.

[0128] When the purification parameters fall within the standard parameter range or the dosing supplementation plan is completed, it indicates that the wastewater has been treated and has reached the standard for reclaimed water or discharge. Therefore, the remaining types and quantities of chemicals are obtained.

[0129] Step 13: Search for the corresponding drug pool number group in the drug database based on the remaining types of drugs.

[0130] The chemical treatment tank number group refers to a combination of unique numbers for other sewage tanks connected to the corresponding sewage tank number. This chemical treatment tank number group does not include the sewage tank number. The method for finding the chemical treatment tank number group is as follows: the system retrieves the corresponding chemical treatment tank number group from the chemical database based on the remaining chemical types. This chemical database stores a mapping relationship between remaining chemical types and chemical treatment tank number groups. Other sewage tanks connected to this sewage tank are pre-numbered and entered into the chemical database by personnel skilled in the art. When the system detects remaining chemical types, it automatically retrieves the corresponding chemical treatment tank number group from the chemical database based on the remaining chemical types.

[0131] Step 14: If the medicine pool number group exists, disassemble the medicine pool number group to obtain multiple medicine pool numbers.

[0132] The chemical treatment tank number refers to the unique number of each of the other sewage tanks connected to the corresponding sewage tank number. The chemical treatment tank number is obtained by the system performing structured decomposition processing on the selected chemical treatment tank number group, splitting and extracting the set data in the number group into independent, identifiable individual sewage tank numbers to obtain multiple chemical treatment tank numbers.

[0133] Step 15: Extract the wastewater treatment type group of the treatment tank number.

[0134] The wastewater chemical type group refers to the collection of all chemical types used in the wastewater treatment of the corresponding wastewater treatment tank number. The extraction method here is that the system extracts all chemical types used in past wastewater purification operations for each treatment tank number based on its historical treatment records, and then summarizes and integrates these extracted chemical types to form the wastewater chemical type group.

[0135] Step 16: Determine the medication group based on the type of drug.

[0136] The chemical type group refers to the collection of all chemical types used in the current wastewater treatment process. The chemical type group is determined by the system comprehensively summarizing and integrating all chemical types actually used and replenished in the current wastewater treatment process.

[0137] Step 17: Compare the wastewater treatment drug group with the treatment drug group to obtain similarity ratio values.

[0138] The similarity ratio is a quantitative value that characterizes the degree of overlap and compatibility between two sets of drug types. The calculation method is as follows: First, the system counts the total number of drug types in each drug type group. Then, it compares the drug types in the wastewater treatment drug type group with those in the wastewater treatment drug type group, counting the number of overlaps. Finally, the similarity ratio is calculated using the formula: the similarity ratio equals the number of overlapping drug types divided by the total number of drug types in the treatment drug type group multiplied by 100%. The final result is a similarity ratio expressed as a percentage.

[0139] Step 18: If the similarity ratio reaches the preset fusion ratio threshold, calculate and output the amount of purified wastewater based on the remaining amount of reagent.

[0140] The fusion ratio threshold is a quantitative critical value used to determine whether the compatibility between different wastewater treatment agent groups meets the conditions for reuse of remaining agents across treatment tanks. This fusion ratio threshold is obtained by professionals in the field who pre-set and input it based on wastewater treatment process requirements, agent compatibility standards, and engineering practice experience.

[0141] The volume of purified wastewater refers to the amount of wastewater that can be treated to meet standards using the remaining chemicals. The calculation method for this volume is as follows: the system calculates the volume of wastewater that can be purified by each chemical based on the remaining amount of each chemical and the unit purification capacity parameter of the corresponding chemical. The output method for this volume of purified wastewater is as follows: the system outputs the calculated volume of purified wastewater in real time to the wastewater inter-pool transfer control device and the wastewater transfer execution terminal.

[0142] If the similarity ratio reaches the fusion ratio threshold, it means that the sewage in the treatment tank is highly similar to the sewage in the wastewater tank and can be fused together for treatment. Therefore, the amount of purified sewage is calculated and output based on the remaining amount of the reagent.

[0143] Step 19: If the similarity ratio value does not reach the fusion ratio threshold, determine the corresponding wastewater chemical demand through the chemical tank number.

[0144] Wastewater chemical dosage requirements refer to the theoretical dosage of various chemicals required to treat the wastewater in the corresponding wastewater tank with the specified chemical tank number, ensuring it meets treatment standards. The wastewater dosage requirement is determined by professionals in the field who, based on the wastewater purification standards for different chemical tanks and considering factors such as the water quality parameters and volume of the wastewater, pre-determine the corresponding chemical dosage calculation algorithm or model (e.g., PID control algorithm, multiple linear regression model, etc.) and input it into the system. When the system receives the wastewater parameters corresponding to the chemical tank number, it automatically calculates the corresponding wastewater chemical dosage requirement based on the algorithm or model.

[0145] If the similarity ratio does not reach the fusion ratio threshold, it means that the sewage in the treatment tank cannot be fused with the sewage in the sewage tank for treatment, but just happens to use the same agent. Therefore, the required amount of agent for the corresponding sewage is determined by the number of the treatment tank.

[0146] Step 20: Calculate and output the amount of chemicals to be added to the chemical tank based on the required amount of chemicals for the wastewater and the remaining amount of chemicals.

[0147] The replenishment amount for the dosing tank refers to the additional amount of chemicals that need to be added to the tank. The calculation method involves the system subtracting the remaining amount of chemicals from the required amount for the wastewater. This calculation is performed separately for each type of chemical. The replenishment amount equals the required amount minus the remaining amount. If the result is positive, it represents the actual amount of that type of chemical to be added; if the result is zero or negative, it indicates that no additional addition is needed. The output method involves the system aggregating and integrating the calculated actual replenishment amounts for each type of chemical to generate a standardized replenishment list, which is then sent to the execution terminal of the dosing system in real time.

[0148] The methods for calculating and outputting the replenishment amount of the chemical tank based on the required amount of chemical in the wastewater and the remaining amount of chemical include:

[0149] Step 200: Calculate the percentage of remaining reagent based on the remaining reagent amount and the required reagent amount for wastewater.

[0150] The remaining chemical dosage ratio refers to the ratio of the remaining chemical dosage in the wastewater treatment plant to the required chemical dosage for the wastewater. This ratio is calculated by dividing the remaining chemical dosage by the required chemical dosage for the wastewater.

[0151] Step 201: If the remaining amount of medicine reaches the preset cost-effectiveness threshold, calculate and output the amount of medicine to be added to the medicine tank based on the required amount of medicine for sewage and the remaining amount of medicine.

[0152] The cost-effectiveness threshold refers to the critical value for determining whether to transfer the remaining amount of reagent to the corresponding application tank. This threshold is determined by professionals in the field through engineering economic analysis and process experiments, based on the reagent procurement cost, inter-tank transport energy consumption, reagent loss rate, and process compatibility standards of the wastewater treatment project, and then pre-set and entered into the system.

[0153] If the remaining amount of medicine reaches the cost-effectiveness threshold, it means that there is a lot of medicine left. It can be transferred to the other medicine tanks corresponding to the sewage tank for use to avoid waste. Therefore, the replenishment amount of medicine in the medicine tank is calculated and output based on the required amount of medicine in the sewage and the remaining amount of medicine.

[0154] Step 202: If the remaining amount of medicine does not reach the cost-effectiveness threshold, the amount of medicine required for the wastewater will be output as the amount of medicine to be replenished in the medicine tank.

[0155] If the remaining amount of medicine does not reach the cost-effectiveness threshold, it means that the remaining amount of medicine is very small. At this time, the energy consumed in transmitting it is large. Therefore, the amount of medicine required for the sewage is output as the amount of medicine to replenish the medicine tank.

[0156] Step 203: Integrate the remaining types and quantities of drugs to form waste drug data and output it.

[0157] Waste chemical agent data refers to the aggregated data set of remaining chemical agents and their corresponding remaining quantities that cannot be reused across different treatment tanks and do not require additional replenishment. The integration method for this waste chemical agent data involves the system filtering out remaining chemical agent types and their corresponding remaining quantities whose remaining quantity percentage does not reach the cost-effectiveness threshold and for which there is no matching treatment tank. This data is then structured and integrated according to a preset data format to form the waste chemical agent data. The output method for this waste chemical agent data involves synchronizing it to the wastewater treatment system's chemical agent management platform and environmental monitoring terminal.

[0158] Among them, the methods for integrating and outputting waste drug data based on the remaining types and quantities of drugs include:

[0159] Step 2030: If the remaining dosage does not reach the cost-effectiveness threshold, obtain the reclaimed water demand information.

[0160] Reclaimed water demand information refers to a collection of relevant parameters such as the amount of reclaimed water needed, water quality standards, water usage periods, and transportation routes. This reclaimed water demand information is obtained by connecting the system to a reclaimed water demand management platform or the intelligent monitoring terminal of the water-using unit. The system collects data in real time on reclaimed water demand, water quality requirements, water usage time windows, and transportation nodes, and integrates this data to form the reclaimed water demand information.

[0161] If the remaining amount of the drug does not reach the cost-effectiveness threshold, it means that the remaining drug needs to be discarded or neutralized before being added to the wastewater tank. In order not to affect the use of reclaimed water, we need to obtain information on the demand for reclaimed water.

[0162] Step 2031: Extract the range of water quality parameters from the reclaimed water demand information.

[0163] The water quality parameter range refers to the allowable fluctuation range of various water quality indicators in the reclaimed water demand information that meet the usage requirements of the target water use scenario. The extraction method for the water quality parameter range here is that the system performs structured analysis on the acquired reclaimed water demand information, filters out the core indicators that characterize water quality compliance (such as pH value, chemical oxygen demand (COD), ammonia nitrogen content, suspended solids (SS) concentration, etc.), and extracts the corresponding upper limit, lower limit or standard value of each indicator to obtain the water quality parameter range.

[0164] Step 2032: Calculate the purification over-parameters using the reclaimed water parameters and the remaining amount of reagents.

[0165] The purification excess parameter refers to the core data of reclaimed water quality after adding unusable residual chemicals to a water body that has already met the reclaimed water quality standards. The purification excess parameter is calculated by retrieving the water quality parameters of the compliant reclaimed water (such as pH, COD concentration, ammonia nitrogen content, SS concentration, etc.) and the remaining unusable chemicals. Combined with a water quality impact quantification model (e.g., multiple linear regression model, PID control algorithm, etc.), the changes in various water quality indicators after the addition of each type of residual chemical are calculated based on its chemical characteristics, dosage, and water volume ratio. These changes are then integrated to form the purification excess parameter.

[0166] Step 2033: If the purification over-parameter falls within the water quality parameter range, a reagent ignoring scheme is formed based on the remaining amount and type of reagent and executed.

[0167] The "chemical neglect" scheme refers to a chemical treatment plan where the remaining amount and type of chemicals that cannot be reused across different treatment tanks are directly added to the already compliant reclaimed water without additional neutralization, separation, or disposal. This scheme is generated by first verifying that all parameters of the purification process fall within the range of reclaimed water quality parameters. Then, it extracts the core data on the remaining amount and type of chemicals that cannot be reused across tanks, integrating this data to generate a standardized treatment plan that allows the remaining chemicals to be directly added to the already compliant reclaimed water without additional neutralization, separation, or disposal. The execution of this scheme involves the system distributing the generated standardized chemical neglect plan to the chemical dosing terminal, which then accurately adds the corresponding remaining amount of chemicals to the already compliant reclaimed water.

[0168] If the purification over-parameter falls within the water quality parameter range, it means that even if the remaining reagent is added to the wastewater tank, it will not affect the use of reclaimed water. Therefore, a reagent ignoring scheme is formed and implemented based on the remaining amount and type of reagent.

[0169] Step 2034: If the purification over-parameter does not fall within the water quality parameter range, integrate the remaining types and quantities of reagents to form waste reagent data and output it.

[0170] If the purification over-parameter does not fall within the water quality parameter range, it indicates that adding the remaining reagent to the wastewater tank will affect the reclaimed water in the wastewater tank. In order to prevent the reclaimed water from becoming unusable, waste reagent data is generated and output based on the remaining reagent types and quantities.

[0171] The methods for finding the corresponding drug type and dosage include:

[0172] Step 30: Obtain the actual time period.

[0173] The actual time period refers to the current real-time interval that includes specific year, month, and day information. This actual time period is obtained by the system connecting to the wastewater treatment system's local clock module or network time service, collecting real-time time data including year, month, and day, and integrating it into standard time interval data.

[0174] Step 31: Search for the corresponding sewage situation in the preset historical database according to the actual time period.

[0175] Wastewater status refers to the collection of core water quality parameters such as wastewater type, flow rate, pollutant concentration, and pH value during historical wastewater treatment processes corresponding to a specific time period, as well as related data such as the type and dosage of corresponding chemicals, and treatment effects. The wastewater status lookup method involves the system associating and matching the acquired actual time period with timestamped wastewater treatment records stored in the historical database, filtering out historical data with consistent time dimensions, and integrating them to form the corresponding wastewater status. The historical database stores the mapping relationship between actual time periods and wastewater status. The system automatically records all historical wastewater parameters and the corresponding times. When the system receives a discharge completion signal, it automatically retrieves the actual time period and looks up the corresponding wastewater status based on that time period.

[0176] Step 32: Analyze the wastewater situation to obtain historical wastewater types, historical types of chemicals, and historical dosages.

[0177] Wastewater historical types refer to the specific categories of wastewater treated in historical wastewater treatment processes corresponding to a specific time period. The method for obtaining these wastewater historical types is that the system performs structured analysis on wastewater data retrieved from the historical database, extracts the core data fields representing the wastewater category, and integrates them to form the wastewater historical types. Chemical historical types refer to the specific categories of chemicals added to treat the corresponding wastewater historical types. The method for obtaining these chemical historical types is that the system performs structured analysis on the retrieved wastewater data, extracts the core data fields representing the types of chemicals added, and integrates them to form the chemical historical types. Historical chemical dosage refers to the specific dosage values ​​of various chemical historical types added to treat the corresponding wastewater historical types. The method for obtaining these historical chemical dosage values ​​is that the system performs structured analysis on the retrieved wastewater data, extracts the numerical data fields representing the dosage of various chemicals, and integrates them to form the historical chemical dosage values.

[0178] Step 33: Search for historical wastewater reagent types in the reagent database based on the historical wastewater types.

[0179] Historical wastewater treatment agent categories refer to the set of standard agent categories suitable for treating wastewater of a specific historical type. The search method for historical wastewater treatment agent categories involves the system using the extracted historical wastewater types as search keywords to perform category matching searches in the agent database, filtering out the corresponding standard agent categories, and integrating them to form historical wastewater treatment agent categories.

[0180] Step 34: Determine the actual types of chemicals based on the historical types of wastewater treatment chemicals and the historical types of chemicals used.

[0181] The actual chemical agent types refer to the set of chemical agent categories that meet the treatment standards for the corresponding historical wastewater types and have been verified as effective through historical practical application. The actual chemical agent types are determined by the system performing an intersection operation between the retrieved historical wastewater chemical agent types and the extracted historical chemical agent types. Overlapping chemical agent categories are selected from the two sets of data, and categories that do not meet the standard requirements are removed. Finally, the actual chemical agent types are integrated.

[0182] Step 35: Sort the historical medication dosage according to the preset time arrangement rules to obtain the medication dosage ranking.

[0183] Time-based sorting rules refer to standard rules used to organize historical medication dosage data in an orderly manner according to the time dimension. These rules are obtained by professionals in the field who pre-set them according to chronological order and input them into the system. Dosage sorting refers to the sequence data of medication dosages with timestamps. This dosage sorting is obtained by the system extracting the timestamp information corresponding to historical medication dosages, arranging the historical medication dosage data in an orderly manner according to the time-based sorting rules, and integrating it to generate sequence data containing the time dimension and corresponding medication dosage values.

[0184] Step 36: Analyze the changes in historical medication usage by ranking the medication dosage and combining it with historical medication usage data.

[0185] Historical medication usage changes refer to the collection of data related to the increase or decrease trends, fluctuation ranges, and patterns of change in the dosage of various medications over time. The analysis of historical medication usage changes here involves the system using time-series characteristics based on the dosage ranking, combined with the numerical distribution of historical dosages, and employing statistical analysis methods to calculate the rate of change, extreme fluctuations, and trends of dosage for various medications, integrating these data to form the historical medication usage changes report.

[0186] Step 37: Analyze future medication dosage based on historical changes in medication use and the actual types of medications used.

[0187] Future dosage refers to the estimated dosage of various chemicals needed to treat the current wastewater. The analysis of future dosage involves the system correlating historical trend data of chemical usage with the attribute parameters of the actual chemical types. A dosage prediction algorithm is then used to calculate the estimated dosage of each chemical type, and these calculations are integrated to form the future dosage. Examples of such algorithms include time series forecasting algorithms (ARIMA algorithm) and machine learning regression algorithms (Gradient Boosting Tree Regression (GBRT) algorithm).

[0188] Step 38: Define the actual drug type as the drug type and the future dosage as the drug dosage.

[0189] The method for defining drug type here is that the system directly considers the actual drug type obtained as the drug type. The method for defining drug dosage here is that the system directly considers the future drug dosage obtained as the drug dosage.

[0190] The methods for formulating a dosing regimen include:

[0191] Step 70: Obtain the drug storage quantity corresponding to the drug type.

[0192] The quantity of chemicals stored refers to the actual amount of each type of chemical that is in stock. This quantity is obtained by connecting the system to the chemical storage monitoring module of the wastewater treatment system. The module collects real-time inventory data for each type of chemical, matches it with the category information of the chemical type, and then integrates this data to form the chemical storage quantity.

[0193] Step 71: If the required amount of the agent is greater than the available amount of the agent, analyze the agent's effect based on the type of wastewater and the type of agent.

[0194] Chemical efficacy refers to the quantitative and qualitative evaluation data of core treatment effectiveness in wastewater, such as the removal efficiency of pollutants, the degree of improvement in water quality indicators, and the treatment compliance rate. The method for obtaining chemical efficacy here is that professionals in this field pre-determine the types of chemicals based on different types of wastewater, conduct experiments, obtain the corresponding chemical efficacy, and input it into the system. When the system detects that the required amount of chemical efficacy exceeds the available storage capacity, it automatically retrieves and matches the corresponding chemical efficacy.

[0195] Step 72: If the effect of the medicine is a preset ignore effect, define the medicine type as an ignore type.

[0196] The negligible effect refers to a treatment outcome where the contribution to the removal of pollutants and the improvement of water quality indicators in wastewater is extremely low, and even without the addition of this type of agent, it will not have a significant impact on the effluent quality of reclaimed water. The negligible effect is obtained by researchers in the field conducting experiments based on the needs of reclaimed water beforehand and then inputting the results into the system.

[0197] Ignored types refer to the types of chemicals that, even if not added, will not have a significant impact on the quality of the reclaimed water effluent.

[0198] If the effect of the agent is negligible, it means that the agent can turn the sewage into reclaimed water even if it is not added to the sewage tank, and it will not affect the use of the treated reclaimed water. Therefore, the agent type is defined as a negligible type.

[0199] Step 73: After screening the drug types, perform step 6 to obtain the types to be used and define them as abundant types.

[0200] "Sufficient types" refers to reagents in stock that can meet the demand for reagents and can be directly used for current wastewater treatment. The method for obtaining sufficient types is as follows: the system filters out ignored types from the reagent types and then matches them one-to-one with the reagent demand types to obtain usable types that do not contain ignored types, and these are considered sufficient types.

[0201] Step 74: Obtain the corresponding amount of surplus medicine based on the surplus type, and combine the surplus type, the neglected type and its corresponding medicine storage amount to form a neglect scheme.

[0202] The adequate dosage refers to the specific dosage values ​​of various agents that correspond one-to-one with the available types and meet the current wastewater treatment requirements. The adequate dosage is obtained by the system calculating and determining the corresponding dosage for each available agent based on the current wastewater treatment process parameters and water quality indicators, combined with the characteristics of the available agent types, and finally integrating these values ​​to form the adequate dosage.

[0203] An "ignorance scheme" refers to a targeted dosing plan that adds only the existing inventory of the ignored types of chemicals to the wastewater treatment plant, rather than the required quantity, while simultaneously adding the surplus type of chemicals according to the surplus dosage. This ignore scheme is formed by systematically integrating three core data categories: surplus types and their corresponding surplus dosages, ignored types and their corresponding remaining chemical storage quantities. The scheme is then developed by adding surplus types according to the required quantity and ignored types according to the remaining storage quantity, ultimately creating an ignore scheme that can be directly used to guide wastewater treatment plant chemical dosing operations.

[0204] Step 75: If the effect of the drug is not negligible, generate and output a corresponding drug shortage signal based on the drug type and drug storage quantity.

[0205] A drug shortage signal is a warning message used to alert staff that the inventory of a certain type of drug is insufficient. This signal is generated by comparing the system's existing drug inventory with the required inventory. If the inventory is less than the required inventory, the system automatically extracts core data such as the drug type, inventory deficit, and wastewater treatment process compatibility priority. This data is then filled into a signal format template (e.g., basic drug shortage signal template, tiered warning drug shortage signal template, etc.) to generate the corresponding drug shortage signal. The signal is output by the system synchronously pushing it to the wastewater treatment system monitoring center's large screen, the local pop-up window on the dosing room's industrial control computer, the staff's mobile management app, and the operation and maintenance platform's message notification module, based on a preset signal transmission path and terminal type.

[0206] If the effect of the agent is not negligible, it means that this type of agent is required to treat the wastewater pond. In order to avoid incomplete treatment, a corresponding shortage signal is generated and output based on the type of agent and the amount of agent stored.

[0207] Step 76: If the required amount of medicine is less than the available amount of medicine, proceed to steps 6 and 7 to form a dosing plan.

[0208] If the required amount of the agent is less than the available amount, it means that the available amount is sufficient to meet the demand, and the wastewater can be treated directly. Therefore, steps 6 to 7 are executed to form a dosing plan.

[0209] This also includes:

[0210] Step 750: When a drug shortage signal is received, execute steps 1 to 3 to obtain the drug type and define it as a future type.

[0211] Future types refer to the types of reagents to be replenished for the next wastewater treatment need. Here, the definition of future types is that after the system receives a reagent shortage signal, it automatically re-executes steps 1 to 3 to obtain the reagent types and regards those reagent types as future types.

[0212] When a drug shortage signal is received, it means that the sewage in the sewage tank cannot be treated temporarily. In order to determine whether subsequent sewage will continue to be discharged into this sewage tank, steps 1 to 3 are executed to obtain the drug type and define it as the future type.

[0213] Step 751: Repeat step 70 to obtain multiple drug storage quantities and compare them with the corresponding drug demand quantities.

[0214] To determine whether subsequent wastewater will be discharged into the wastewater pond, the amount of reagent stored is compared with the amount of reagent required.

[0215] Step 752: If the required amount of chemicals is less than the available amount of chemicals, find other treatment tank numbers based on the wastewater tank number and the future type.

[0216] Other treatment pool numbers refer to unique identification codes for other wastewater pools that possess treatment processes compatible with future types of chemicals and are in a state of pending treatment or operation. The method for finding other treatment pool numbers is as follows: the system filters non-current wastewater pools based on the current wastewater pool's treatment standards, wastewater type, and the compatibility process requirements of future chemicals, extracts their unique numbers, and integrates them to form other treatment pool numbers.

[0217] If the required amount of chemicals is less than the available amount of chemicals, it means that the wastewater can be treated into reclaimed water. In order to avoid the situation where it is mixed with the untreated wastewater in the wastewater tank and becomes untreated wastewater, other treatment tank numbers are searched based on the wastewater tank number and the future type.

[0218] Step 753: Replace the wastewater tank number with the other treatment tank number to obtain the updated treatment tank number and output it.

[0219] The updated treatment tank number refers to the unique number of the new wastewater tank that replaces the original wastewater tank number that generated the chemical shortage signal. The updated treatment tank number is obtained by the system acquiring other treatment tank numbers and then comprehensively evaluating them based on core parameters such as the current operating status of each other treatment tank, wastewater type suitability, process compatibility level, and treatment load rate. The system selects the target treatment tank number with the highest score and replaces it with the original wastewater tank number that generated the chemical shortage signal, generating a new wastewater tank number. The updated treatment tank number is output by the system pushing the generated updated treatment tank number to the relevant modules of the wastewater treatment system (e.g., the tank process control module, the chemical dosing management module, and the system monitoring terminal) according to a preset scheduling instruction transmission protocol.

[0220] The methods for formulating a dosing regimen also include:

[0221] Step 77: Search for the corresponding pollutant type in the preset pollution database based on the type of reagent and the type of wastewater.

[0222] Pollutant types refer to the specific categories of byproduct pollutants, such as precipitates and suspended solids, generated during wastewater treatment through chemical reactions and physical sedimentation when a particular type of reagent is applied to a corresponding type of wastewater. The pollution database stores the mapping relationship between reagent types, wastewater types, and pollutant types. Experts in the field pre-determine the types of pollutants generated when each type of reagent treats a corresponding type of wastewater through experiments, and then input this information into the pollution database. When wastewater treatment is required, the database is automatically searched to find the corresponding pollutant types based on the reagent type and wastewater type.

[0223] Step 78: If the type of pollutant is not available, determine the dosing plan based on the type and dosage of the drug used.

[0224] If the type of pollutant is not present, it means that the wastewater can be treated directly without worrying about the subsequent pollutants. Therefore, the dosing plan is determined based on the type and dosage of the chemicals used.

[0225] Step 79: If a pollutant type exists, search for the corresponding pollution removal solution in the preset pollution removal database based on the pollutant type.

[0226] A pollution control plan refers to a standardized treatment plan for pollutants. The pollution control database stores a mapping relationship between pollutant types and pollution control plans. Experts in the field pre-determine the treatment methods and specific operating procedures for each pollutant, then integrate these into a pollution control plan and input it into the database. When the system detects that the wastewater will generate pollutants, it automatically retrieves and matches the corresponding pollution control plan.

[0227] If a pollutant type is present, it indicates that impurities will be generated during the wastewater treatment process, and the impurities in the reclaimed water need to be treated. Therefore, the corresponding pollution removal solution is searched in the preset pollution removal database based on the pollutant type.

[0228] Step 80: When a decontamination plan exists, a final plan is formed based on the decontamination plan and the chemical dosing plan and then executed.

[0229] The final solution refers to the sum of solutions for treating wastewater and the generated impurities. Here, the final solution is formed by the system integrating data from the dosing and decontamination schemes. First, the dosing parameters and corresponding dosing sequences of the chemicals in the dosing scheme are extracted. Then, the by-product pollutant treatment process path, equipment operating parameters, and effect monitoring nodes in the decontamination scheme are integrated. Next, following the process logic of first treating wastewater with chemicals and then executing the decontamination process to remove by-product impurities, the execution steps of the two schemes are sequentially arranged, process connection parameters and contingency plans for abnormal situations are added. Finally, the system's built-in scheme verification module verifies the process compatibility and parameter rationality of the integrated scheme. Once verification is successful, a final solution covering the entire process of wastewater purification and impurity removal is generated. The final solution is executed by the system issuing instructions to each execution module of the wastewater treatment system according to the process sequence and parameter thresholds of the final solution, driving the coordinated operation.

[0230] This also includes solutions for when a decontamination plan is unavailable, including:

[0231] Step 81: Determine the pollutant situation based on the type of pollutant.

[0232] Pollutant status refers to the characteristics of the occurrence of byproduct pollutants generated from the reaction of chemicals with wastewater. The pollutant status is determined by the system using online suspended solids monitoring sensors and bottom sediment thickness detectors deployed within the wastewater tank to collect data on the concentration of suspended pollutants in the water and the thickness of sediment at the bottom of the tank, respectively. The monitoring data is then integrated to form a clear pollutant status.

[0233] Step 82: If the pollutant situation is the preset object situation, find the corresponding temporary water tank number according to the sewage tank number.

[0234] The "object condition" refers to the specific state in which the upper layer of clear water can be directly extracted to achieve solid-liquid separation. This object condition is obtained by those skilled in the art through multiple prior experiments to determine the conditions under which water can be directly extracted, and then inputting this information into the system.

[0235] The temporary storage tank number is a unique identification code for a dedicated tank used to temporarily store the upper clarified water extracted from the sewage tank. The method for finding the temporary storage tank number is the same as the method for finding the chemical treatment tank number group described in step 13, and will not be repeated here.

[0236] If the pollutant is an object, it means that the pollutant will not mix with the reclaimed water. Therefore, find the corresponding temporary storage tank number based on the sewage tank number.

[0237] Step 83: Determine and implement a water transfer plan based on the type of pollutant, the wastewater tank number, and the temporary storage tank number.

[0238] A water transfer plan refers to a standardized operational procedure for the extraction, temporary storage, and subsequent treatment of upper-level clean water, including pumping equipment operating parameters, water flow transmission paths, receiving rules for temporary storage tanks, process monitoring nodes, and contingency plans for abnormal situations. The water transfer plan is determined by the system based on the type of pollutant, the wastewater tank number, and the temporary storage tank number, combined with the pollutant settling characteristics to determine the pumping depth threshold and pumping velocity. The system plans the water flow transmission path according to the pipeline layout of the wastewater tank and the temporary storage tank, matches the real-time capacity status of the temporary storage tank to determine the receiving priority, and embeds online water quality monitoring nodes during the pumping process. Finally, the system integrates these elements to generate the water transfer plan. The execution of this water transfer plan involves the system driving the coordinated operation of each execution unit in stages according to the plan parameters and procedures.

[0239] Step 84: If the pollutant situation is the preset water body situation, determine the salvage plan according to the sewage tank number and the type of pollutant and execute it.

[0240] The water condition refers to the state in which byproduct pollutants generated from the reaction of chemicals and wastewater do not undergo effective sedimentation and remain uniformly dispersed in the water body in a suspended or colloidal state. This makes it impossible to achieve solid-liquid separation by directly extracting the upper layer of clear water, and these pollutants are simultaneously transferred to the reclaimed water during the pumping process. The method for obtaining this water condition is consistent with the method determined in step 82, inputting the situation where direct pumping is not possible into the system.

[0241] A salvage plan refers to a method for cleaning up suspended or colloidal byproduct pollutants dispersed in reclaimed water. The salvage plan is determined by the system based on the tank structure parameters, water volume, and current operating conditions corresponding to the wastewater tank number, combined with the physicochemical properties of the pollutants, such as particle size, surface charge, and density. Then, based on the tank conditions and pollutant concentration, equipment operating parameters are set, and online monitoring nodes for pollutant concentration, emergency switching plans for equipment failures, and salvage effect verification standards are embedded. Finally, the entire process is integrated to generate the salvage plan.

[0242] If the pollutant is in the form of water, it means that pure reclaimed water cannot be extracted directly. Therefore, a dredging plan is determined and implemented based on the sewage tank number and the type of pollutant.

[0243] Based on the same inventive concept, embodiments of the present invention provide an intelligent dosing system for distributed wastewater treatment.

[0244] One example is an intelligent dosing system based on distributed wastewater treatment, comprising:

[0245] The acquisition module is used to acquire the wastewater tank number, wastewater parameters, reclaimed water demand information, actual time period, and reagent storage quantity.

[0246] A memory for storing the program of a control method for an intelligent dosing method based on distributed wastewater treatment;

[0247] The processor loads and executes programs from memory.

[0248] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the above-described division of functional modules is used as an example.
