[0002] Currently, wastewater treatment processes generally utilize automated instruments for data collection. However, the analysis of massive amounts of monitoring data still relies on manual experience, leading to significant delays in detecting abnormal conditions such as equipment malfunctions and water quality exceeding standards, thus failing to meet real-time monitoring requirements. Therefore, improving the response speed to abnormal situations in wastewater treatment remains a problem that needs to be addressed.

[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0004] The main objective of this application is to provide a method, apparatus, equipment, and storage medium for monitoring the status of a wastewater treatment process, aiming to solve the technical problem of how to improve the response speed to abnormal situations during wastewater treatment.

[0005] To achieve the above objectives, this application proposes a method for monitoring the status of a wastewater treatment process, the method comprising:

[0006] Real-time collection of wastewater operating data from wastewater treatment facilities;

[0007] Based on the aforementioned wastewater condition data, monitor wastewater quality compliance, key facility operation status, and water balance to obtain monitoring data;

[0008] The warning level is determined and an alarm is issued based on the monitoring data.

[0009] In one embodiment, the step of monitoring wastewater quality compliance, critical facility operation status, and water balance based on the wastewater condition data to obtain monitoring data includes:

[0010] Based on the wastewater operating data, monitor whether the pH value and redox potential value of the wastewater comply with regulations, and obtain wastewater quality compliance monitoring data;

[0011] Based on the wastewater operating data, monitor whether the chemical dosing facilities in the reaction tank and the aeration facilities in the biological treatment tank are operating normally, and obtain facility operation monitoring data;

[0012] Based on the wastewater operating condition data, monitor whether water balance is achieved in each step of the wastewater treatment process to obtain water balance monitoring data for the treatment process.

[0013] Based on the wastewater operating data, monitor whether the final wastewater discharge reaches water balance, and obtain the final water balance monitoring data.

[0014] In one embodiment, the step of monitoring the pH and redox potential values ​​of wastewater based on the wastewater condition data to obtain wastewater quality compliance monitoring data includes:

[0015] Determine whether wastewater treatment is in progress based on the wastewater condition data.

[0016] When wastewater treatment is in progress, the pH value and redox potential value of the wastewater in the reaction tank are obtained based on the wastewater operating data.

[0017] The pH value is compared with a preset pH threshold, and the oxidation-reduction potential value is compared with a preset oxidation-reduction potential threshold. Based on the comparison results, wastewater quality compliance monitoring data is obtained.

[0018] In one embodiment, the step of monitoring whether the chemical dosing facility in the reaction tank and the aeration facility in the biological treatment tank are operating normally based on the wastewater condition data, and obtaining facility operation monitoring data, includes:

[0019] Determine whether wastewater treatment is in progress based on the wastewater condition data.

[0020] When wastewater treatment is in progress, the current of the influent booster pump for the reaction tank and the current of the influent booster pump for the biological treatment tank are obtained based on the wastewater operating data.

[0021] The system determines whether the chemical dosing facility in the reaction tank is operating normally based on whether the current of the influent booster pump in the reaction tank is greater than a preset first current threshold, and determines whether the aeration facility in the biological treatment tank is operating normally based on whether the current of the influent booster pump in the biological treatment tank is greater than a preset second current threshold, thereby obtaining facility operation monitoring data.

[0022] In one embodiment, the step of monitoring whether water balance is achieved within each step of the wastewater treatment process based on the wastewater operating condition data, and obtaining water balance monitoring data for the treatment process, includes:

[0023] Based on the wastewater operating data, obtain the influent lift pump current data and effluent lift pump current data for each step;

[0024] Based on the inlet pump current data, the average inlet pump current of the day and the average inlet pump current over a preset historical period are obtained, and the deviation value of the inlet pump current is calculated based on the average inlet pump current of the day and the average inlet pump current over a preset historical period.

[0025] Based on the water lift pump current data, the average water lift pump current of the day and the average water lift pump current over a preset historical period are obtained, and the deviation value of the water lift pump current is calculated based on the average water lift pump current of the day and the average water lift pump current over a preset historical period.

[0026] The absolute difference between the current deviation values ​​of the inlet booster pump and the outlet booster pump is used to determine whether water balance has been achieved in each step, thus obtaining water balance monitoring data for the treatment process.

[0027] In one embodiment, the step of monitoring whether the final wastewater discharge reaches water balance based on the wastewater condition data, and obtaining the final water balance monitoring data, includes:

[0028] Based on the wastewater operating data, obtain the influent booster pump current data and the wastewater discharge outlet flow data for each step;

[0029] Based on the inlet pump current data, the average inlet pump current of the day and the average inlet pump current over a preset historical period are obtained, and the deviation value of the inlet pump current is calculated based on the average inlet pump current of the day and the average inlet pump current over a preset historical period.

[0030] Based on the flow data of the sewage discharge outlet, the average sewage discharge flow rate of the day and the average sewage discharge flow rate over a preset historical period are obtained, and the sewage discharge flow rate deviation value is calculated based on the average sewage discharge flow rate of the day and the average sewage discharge flow rate over a preset historical period.

[0031] The absolute difference in flow rate between the deviation value of the influent booster pump current and the deviation value of the sewage discharge flow rate is used to determine whether water balance has been achieved in each step, and the final water balance monitoring data is obtained.

[0032] In one embodiment, the step of determining the warning level and issuing an alarm based on the monitoring data includes:

[0033] When the monitoring data is wastewater quality compliance monitoring data, the first abnormal duration when the pH value of the wastewater in the reaction tank exceeds the preset pH threshold and the second abnormal duration when the oxidation-reduction potential value of the wastewater in the reaction tank exceeds the preset oxidation-reduction potential threshold are obtained based on the wastewater quality compliance monitoring data. The warning level is determined and an alarm is issued based on the first abnormal duration and the second abnormal duration.

[0034] When the monitoring data is facility operation monitoring data, the third abnormal duration when the current of the reaction tank inlet booster pump is greater than the preset first current threshold and the fourth abnormal duration when the current of the biochemical tank inlet booster pump is greater than the preset second current threshold are obtained based on the facility operation monitoring data, and the warning level is determined and an alarm is issued based on the third abnormal duration and the fourth abnormal duration.

[0035] When the monitoring data is the water balance monitoring data of the treatment process, the absolute difference of the current between the current deviation value of the inlet booster pump and the current deviation value of the outlet booster pump is obtained based on the water balance monitoring data of the treatment process, and the warning level is determined and an alarm is issued based on the magnitude of the absolute difference of the current.

[0036] When the monitoring data is the final water balance monitoring data, the absolute difference in flow rate between the inlet booster pump current deviation value and the sewage discharge flow rate deviation value is obtained based on the final water balance monitoring data, and the warning level is determined and an alarm is issued based on the magnitude of the absolute difference in flow rate.

[0037] Furthermore, to achieve the above objectives, this application also proposes a status monitoring device for a wastewater treatment process, the wastewater treatment process status monitoring device comprising:

[0038] The data acquisition module is used to collect real-time data on the operating conditions of wastewater treatment facilities.

[0039] The monitoring module is used to monitor the compliance of wastewater quality, the operating status of key facilities, and the water balance based on the wastewater condition data, and to obtain monitoring data.

[0040] The alarm module is used to determine the warning level and issue an alarm based on the monitoring data.

[0041] In addition, to achieve the above objectives, this application also proposes a status monitoring device for a wastewater treatment process, the device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the status monitoring method for the wastewater treatment process as described above.

[0042] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the state monitoring method for the wastewater treatment process as described above.

[0043] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the state monitoring method for the wastewater treatment process as described above.

[0044] This application provides a method for monitoring the status of a wastewater treatment process. The method involves collecting wastewater operating data from the wastewater treatment facility in real time; monitoring wastewater quality compliance, the operating status of key facilities, and water balance based on the wastewater operating data to obtain monitoring data; and determining the early warning level and issuing an alarm based on the monitoring data.

[0045] In summary, this application, by monitoring wastewater operating data in real time and issuing alarms of different levels based on the monitoring results, can quickly monitor abnormal situations in wastewater treatment and issue alarms, thereby improving the response speed to abnormal situations in the wastewater treatment process.

[0055] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0056] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0057] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0058] The main solution of this application is to collect wastewater operating data of wastewater treatment facilities in real time; monitor wastewater quality compliance, key facility operation status and water balance based on the wastewater operating data to obtain monitoring data; and determine the early warning level and issue an alarm based on the monitoring data.

[0059] Currently, wastewater treatment processes generally utilize automated instruments for data collection. However, the analysis of massive amounts of monitoring data still relies on manual experience, leading to significant delays in detecting abnormal conditions such as equipment malfunctions and water quality exceeding standards, thus failing to meet real-time monitoring requirements. Therefore, improving the response speed to abnormal situations in wastewater treatment remains a problem that needs to be addressed.

[0060] This application monitors wastewater operating data in real time and issues alarms of different levels based on the monitoring results, which can quickly detect abnormal situations in wastewater treatment and issue alarms, thereby improving the response speed to abnormal situations in the wastewater treatment process.

[0061] Based on this, embodiments of this application provide a method for monitoring the status of a wastewater treatment process, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the wastewater treatment process status monitoring method of this application.

[0062] In this embodiment, the wastewater treatment process status monitoring method includes steps S10 to S30:

[0063] Step S10: Collect wastewater operating data of the wastewater treatment facility in real time;

[0064] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device capable of performing the above functions, such as a wastewater treatment process status monitoring device. The following description uses a wastewater treatment process status monitoring device as an example to illustrate this embodiment and the subsequent embodiments.

[0065] It should be noted that the wastewater treatment process can be referenced. Figure 2 , Figure 2 This is a flow chart of the wastewater treatment process. Figure 2The wastewater treatment process includes a wastewater collection tank, a reaction tank, a sedimentation tank, a equalization tank, a biological treatment tank, and a discharge outlet. Wastewater treatment process data includes wastewater lift pump current data, data from wastewater treatment process monitoring instruments such as pH meters or Oxidation-Reduction Potential (ORP) meters, operating current of the chemical dosing pumps in the wastewater reaction tank, operating circuit data of the aeration facilities in the biological treatment tank, and data from the online monitoring equipment at the discharge outlet.

[0066] Step S20: Monitor the compliance of wastewater quality, the operating status of key facilities, and the water balance based on the wastewater condition data to obtain monitoring data;

[0067] It should be noted that wastewater quality compliance includes whether the pH or ORP of the wastewater in the reaction tank is within the normal range; the operational status of key facilities includes whether the chemical dosing facilities in the reaction tank are adding chemicals normally and whether the aeration facilities in the biological treatment tank are operating normally; and water balance includes whether the water balance relationship during the wastewater treatment process is normal and whether the water balance relationship between the wastewater treatment and the discharge outlet is normal.

[0068] Step S30: Determine the warning level and issue an alarm based on the monitoring data.

[0069] Understandably, this embodiment divides the warning levels into three levels. A level 3 warning indicates that the overall sewage treatment situation has a minor impact and serves as a daily reminder. A level 2 warning indicates that the overall sewage treatment situation has a small impact and promptly alerts the sewage treatment provider to repair any malfunctions. A level 1 warning indicates that the overall sewage treatment situation has a significant impact and promptly alerts the sewage treatment provider to check whether the sewage treatment quality meets the discharge requirements, and if necessary, to return the sewage for reprocessing.

[0070] In one feasible approach, the step of determining the early warning level and issuing an alarm based on the monitoring data includes: when the monitoring data is wastewater quality compliance monitoring data, obtaining a first abnormal duration for the pH value of the wastewater in the reaction tank exceeding a preset pH threshold and a second abnormal duration for the oxidation-reduction potential value of the wastewater in the reaction tank exceeding a preset oxidation-reduction potential threshold based on the wastewater quality compliance monitoring data, and determining the early warning level and issuing an alarm based on the first abnormal duration and the second abnormal duration; when the monitoring data is facility operation monitoring data, obtaining a third abnormal duration for the current of the influent booster pump in the reaction tank exceeding a preset first current threshold and a second abnormal duration for the current of the influent booster pump in the biological treatment tank exceeding a preset first current threshold based on the facility operation monitoring data. If the flow exceeds a preset second current threshold for a fourth abnormal duration, a warning level is determined and an alarm is triggered based on the third and fourth abnormal durations. When the monitoring data is process water balance monitoring data, the absolute difference between the influent lift pump current deviation value and the effluent lift pump current deviation value is obtained based on the process water balance monitoring data, and a warning level is determined and an alarm is triggered based on the magnitude of the absolute difference. When the monitoring data is final water balance monitoring data, the absolute difference between the influent lift pump current deviation value and the sewage discharge flow rate deviation value is obtained based on the final water balance monitoring data, and a warning level is determined and an alarm is triggered based on the magnitude of the absolute difference.

[0071] Understandably, when the monitoring data pertains to wastewater quality compliance, if either the pH or ORP value of the wastewater in the reaction tank exceeds the threshold range after a 5-minute average, a Level 3 warning is triggered, with a 5-minute interval until wastewater treatment ceases. If either the pH or ORP value exceeds the threshold range after a 20-minute average, a Level 2 warning is triggered, with a 20-minute interval until wastewater treatment ceases. If either the pH or ORP value exceeds the threshold range after a 60-minute average, a Level 1 warning is triggered, with a 60-minute interval until wastewater treatment ceases. In actual operation, if the wastewater treatment facility's reaction tank is normally operating, the wastewater pH should be adjusted to above 8 (alkaline) to properly convert pollutants into sludge and other sediments. If, during a monitoring session, the reaction tank is in wastewater treatment mode at 22:00 (increased inlet pump current), and from 22:00 to 22:40 the pH in the reaction tank is below 8, with an average pH of around 5 indicating acidity, the reaction tank failed to treat wastewater normally during this period, and the system calculates and outputs a warning. (For reference...) Figure 3 , Figure 3 This is a diagram illustrating acid / alkalinity alarms.

[0072] Understandably, when the monitoring data refers to facility operation monitoring data, if the operating current of the reaction tank dosing pump or the operating current of the biological treatment tank aeration equipment exceeds 0 for 15 minutes and its maximum value equals 0, a Level III warning is triggered, with a warning interval of 15 minutes, until wastewater treatment stops; if the operating current of the reaction tank dosing pump or the operating current of the biological treatment tank aeration equipment exceeds 0 for 30 minutes and its maximum value equals 0, a Level II warning is triggered, with a warning interval of 30 minutes, until wastewater treatment stops; if the operating current of the reaction tank dosing pump or the operating current of the biological treatment tank aeration equipment exceeds 0 for 60 minutes and its maximum value equals 0, a Level I warning is triggered, with a warning interval of 60 minutes, until wastewater treatment stops. In actual operation, if sodium sulfide is added to the reaction tank during normal wastewater treatment, and it is detected that on a certain day at 13:30, the reaction tank was entering the wastewater treatment state (the influent lift pump current increased), and subsequently, the operating current of the reaction tank dosing pump remained at 0 for an extended period until 15:00, an abnormal duration of 90 minutes, during which the reaction tank failed to treat wastewater normally, the system calculates and outputs a warning. (For reference...) Figure 4 , Figure 4 This is a diagram illustrating the warning message that no medication has been added.

[0073] It is understood that the water balance in the treatment process refers to the water balance of a single step, such as the water volume in the reaction tank or the water volume balance in the biological treatment tank. When the monitoring data is the water balance monitoring data of the treatment process, the absolute difference between the current deviation values ​​of the influent booster pump and the effluent booster pump is obtained based on the water balance monitoring data. When the absolute difference is greater than or equal to 0.20 but less than 0.40, a level three warning is triggered; when the absolute difference is greater than or equal to 0.40 but less than 1.00, a level two warning is triggered; and when the absolute difference is greater than or equal to 1.00, a level one warning is triggered.

[0074] Understandably, the final water balance refers to the balance between the influent volume at each step and the final effluent volume. When the monitoring data is the final water balance monitoring data, the absolute difference between the influent booster pump current deviation value and the sewage discharge flow rate deviation value is obtained based on the final water balance monitoring data. When the absolute difference is greater than or equal to 0.20 but less than 0.40, a level 3 flow rate warning is triggered. When the absolute difference is greater than or equal to 0.40 but less than 1.00, a level 2 warning is triggered. When the absolute difference is greater than or equal to 1.00, a level 1 warning is triggered.

[0075] This embodiment provides a method for monitoring the status of a wastewater treatment process. The method involves collecting wastewater operating data from the wastewater treatment facility in real time; monitoring wastewater quality compliance, the operating status of key facilities, and water balance based on the wastewater operating data to obtain monitoring data; and determining the early warning level and issuing an alarm based on the monitoring data.

[0076] In summary, this embodiment, by monitoring wastewater operating data in real time and issuing alarms of different levels based on the monitoring results, can quickly monitor abnormal situations in wastewater treatment and issue alarms, thereby improving the response speed to abnormal situations in the wastewater treatment process.

[0077] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 5 Step S20 also includes steps S201 to S204:

[0078] Step S201: Monitor the pH and oxidation-reduction potential of the wastewater according to the wastewater condition data to determine whether they comply with regulations, and obtain wastewater quality compliance monitoring data;

[0079] It should be noted that wastewater quality compliance includes whether the pH value and oxidation-reduction potential value are compliant. pH value and oxidation-reduction potential value are important standards for water quality.

[0080] In one feasible approach, the step of monitoring the pH and redox potential values ​​of wastewater based on the wastewater condition data to obtain wastewater quality compliance monitoring data includes: determining whether wastewater treatment is underway based on the wastewater condition data; when wastewater treatment is in progress, obtaining the pH and redox potential values ​​of the wastewater in the reaction tank based on the wastewater condition data; comparing the pH value with a preset pH threshold and comparing the redox potential value with a preset redox potential threshold, and obtaining wastewater quality compliance monitoring data based on the comparison results.

[0081] Understandably, if the current of the influent booster pump to the reaction tank is X, since there are generally multiple booster pumps that are used interchangeably or simultaneously, the current of the influent booster pump to the reaction tank is X = A + B, where A is the current of one booster pump in the reaction tank, and B is the current of another booster pump in the reaction tank. When the real-time data X ≥ 0.5, the reaction tank is considered to be in wastewater treatment mode. When the reaction tank is in treatment mode, the pH or ORP of the reaction tank is correlated and judged. If the pH or ORP of the reaction tank is not within the set range, multi-level early warning is issued, where the set range is determined according to the treatment process.

[0082] Step S202: Monitor whether the chemical dosing facilities in the reaction tank and the aeration facilities in the biological treatment tank are operating normally based on the wastewater condition data, and obtain facility operation monitoring data;

[0083] It should be noted that the normal operation of the facilities can be determined by the current of the influent pumps of the chemical dosing system in the reaction tank and the aeration system in the biological treatment tank.

[0084] In one feasible approach, it is determined whether wastewater treatment is in progress based on the wastewater operating data; when wastewater treatment is in progress, the current of the influent booster pump to the reaction tank and the influent booster pump to the biological treatment tank are obtained based on the wastewater operating data; whether the chemical dosing facility to the reaction tank is operating normally is determined based on whether the current of the influent booster pump to the reaction tank is greater than a preset first current threshold, and whether the aeration facility to the biological treatment tank is operating normally is determined based on whether the current of the influent booster pump to the biological treatment tank is greater than a preset second current threshold, thereby obtaining facility operation monitoring data.

[0085] Understandably, if the current of the influent booster pump to the reaction tank is X, since there are generally multiple influent booster pumps that are used interchangeably or simultaneously, the current of a certain reaction tank's influent booster pump is X = A + B, where A is the current of one booster pump in the reaction tank, and B is the current of another booster pump in the reaction tank. When the real-time data X ≥ 0.5, the reaction tank is considered to be in wastewater treatment mode. When the reaction tank is in treatment mode, a correlation judgment is made on whether the dosing of chemicals in the reaction tank is normal. If the operating current of the dosing pump does not meet the set requirements, a multi-level warning is issued.

[0086] Step S203: Monitor whether water balance is achieved in each step of the wastewater treatment process based on the wastewater condition data, and obtain water balance monitoring data of the treatment process;

[0087] It should be noted that the water balance in the treatment process refers to the water balance of a single step, such as the water volume in the reaction tank or the water volume in the biological treatment tank.

[0088] In one feasible approach, the influent lift pump current data and effluent lift pump current data for each step are obtained based on the wastewater operating condition data. Based on the influent lift pump current data, the average influent lift pump current for the current day and the average influent lift pump current over a preset historical period are obtained, and the influent lift pump current deviation value is calculated based on these two values. Based on the effluent lift pump current data, the average effluent lift pump current for the current day and the average effluent lift pump current over a preset historical period are obtained, and the effluent lift pump current deviation value is calculated based on these two values. The absolute difference between the influent lift pump current deviation value and the effluent lift pump current deviation value is used to determine whether each step has achieved water balance, thus obtaining water balance monitoring data for the treatment process.

[0089] Understandably, if the current of the influent lift pump in a certain stage of the wastewater treatment tank system is X1, and the current of the effluent lift pump is X2, then since there are generally multiple influent and effluent lift pumps that are used alternately or simultaneously, X1 = A + B, where A is the current of one influent lift pump in the step, and B is the current of another influent lift pump in the step; X2 = C + D, where C is the current of one effluent lift pump in the step, and D is the current of another effluent lift pump in the step. The deviation value is calculated as follows:

[0090] X 1(偏差值) =X 1(当天日均值) / X 1(前30天均值)

[0091] X 2(偏差值) =X 2(当天日均值) / X 2(前30天均值)

[0092] Therefore, the absolute difference in current is |X1-X2|. When the difference between X1 and X2 is too large, it is considered that the water volume deviates from conservation.

[0093] Step S204: Monitor whether the final sewage discharge reaches water balance based on the sewage condition data, and obtain the final water balance monitoring data.

[0094] It should be noted that the final water balance refers to the balance between the water inflow at each step and the water flow at the final outlet.

[0095] In one feasible approach, the influent lift pump current data and the sewage discharge outlet flow rate data for each step are obtained based on the sewage operating condition data. Based on the influent lift pump current data, the average influent lift pump current for the current day and the average influent lift pump current over a preset historical period are obtained, and the influent lift pump current deviation value is calculated based on these two values. Based on the sewage discharge outlet flow rate data, the average sewage discharge flow rate for the current day and the average sewage discharge flow rate over a preset historical period are obtained, and the sewage discharge flow rate deviation value is calculated based on these two values. The absolute difference between the influent lift pump current deviation value and the sewage discharge flow rate deviation value is used to determine whether each step has achieved water balance, thus obtaining the final water balance monitoring data.

[0096] Understandably, if the current of the wastewater treatment system's discharge booster pump is X1, and the flow rate of the discharge outlet monitoring system is X2, then since there are generally multiple drainage pumps that are used alternately or simultaneously, X1 = A + B, where A is the current of one of the influent booster pumps in the step, and B is the current of the other influent booster pump in the step. The deviation value is calculated as follows:

[0097] X 1(偏差值)=X 1(当天日均值) / X 1(前30天均值)

[0098] X 2(偏差值) =X 2(当天日均值) / X 2(前30天均值)

[0099] Therefore, the absolute difference in current is |X1-X2|. When the difference between X1 and X2 is too large, it is considered that the water volume deviates from conservation.

[0100] This embodiment monitors the pH and oxidation-reduction potential of wastewater based on the wastewater condition data to obtain wastewater quality compliance monitoring data; it also monitors the normal operation of the chemical dosing facilities in the reaction tank and the aeration facilities in the biological treatment tank based on the wastewater condition data to obtain facility operation monitoring data; it monitors whether water balance is achieved within each step of the wastewater treatment process based on the wastewater condition data to obtain treatment process water balance monitoring data; and it monitors whether the final wastewater discharge reaches water balance based on the wastewater condition data to obtain final water balance monitoring data. This embodiment monitors multiple indicators of wastewater based on wastewater condition data and applies current detection, which can quickly detect abnormalities and improve the response speed to abnormal situations in the wastewater treatment process.

[0101] This application also provides a status monitoring device for a wastewater treatment process; please refer to [reference needed]. Figure 6 The wastewater treatment process status monitoring device includes:

[0102] The data acquisition module 10 is used to collect real-time wastewater operating data of the wastewater treatment facility;

[0103] Monitoring module 20 is used to monitor the compliance of wastewater quality, the operating status of key facilities and water balance based on the wastewater condition data, and obtain monitoring data;

[0104] The alarm module 30 is used to determine the warning level and issue an alarm based on the monitoring data.

[0105] This embodiment provides a method for monitoring the status of a wastewater treatment process. The method involves collecting wastewater operating data from the wastewater treatment facility in real time; monitoring wastewater quality compliance, the operating status of key facilities, and water balance based on the wastewater operating data to obtain monitoring data; and determining the early warning level and issuing an alarm based on the monitoring data.

[0106] In summary, this embodiment, by monitoring wastewater operating data in real time and issuing alarms of different levels based on the monitoring results, can quickly monitor abnormal situations in wastewater treatment and issue alarms, thereby improving the response speed to abnormal situations in the wastewater treatment process.
