Description

Technical Field

[0001] The present application relates to the technical field of phosphorus pollution source tracing, and specifically to a method and device for tracing the source of phosphorus pollution in rivers and lakes. Background Art

[0002] With the acceleration of industrialization and urbanization, environmental problems are becoming more and more serious. Among them, water pollution has become a key bottleneck restricting the sustainable development of rivers. Phosphorus, as an indispensable nutrient element in aquatic ecosystems, is excessively present and is the main cause of eutrophication of water bodies. Eutrophication causes abnormal proliferation of algae, consumes a large amount of dissolved oxygen, and threatens the living space of other aquatic organisms, seriously disrupting the natural balance of aquatic ecosystems.

[0003] In order to accurately assess the current status and dynamic changes of phosphorus pollution in rivers and lakes, scientific phosphorus content testing is required. However, understanding the current status of pollution alone is not enough to fully respond to environmental challenges, and in-depth tracing of the sources of phosphorus pollution is also crucial. Given that different pollution sources contribute differently to the phosphorus load in water bodies and targeted governance measures need to be taken, it is particularly important to conduct a detailed source tracing analysis of phosphorus pollution. At present, although the phosphorus pollution status of rivers and lakes can be confirmed through water quality testing, the tracing process still mainly relies on traditional methods of manual on-site investigations and sampling analysis. This method is inefficient and cannot obtain pollution source information in a timely manner.

[0004] Therefore, there is an urgent need for a method and device for tracing the source of phosphorus pollution in rivers and lakes that can solve the above-mentioned technical problems. Summary of the invention

[0005] The present application provides a method and device for tracing the source of phosphorus pollution in rivers and lakes. The method monitors the changes in water quality in rivers and lakes in real time. After determining that the monitoring point is in a state of phosphorus pollution, it automatically divides the area for further monitoring and determines new monitoring points, narrows the search range for pollution sources, and then determines the type of phosphorus pollution. The target pipeline is checked in a targeted manner, thereby quickly locating the source of pollution. This method of checking is more efficient than manual blind searching and can greatly shorten the tracing time.

[0006] In the first aspect, the present application provides a method for tracing the phosphorus pollution in rivers and lakes, which is applied to a server, and the method includes: obtaining first monitoring data corresponding to a first monitoring point, the first monitoring point is any monitoring point set on the surface of a target river or a target lake, and the first monitoring data is data obtained by monitoring phosphorus at the first monitoring point; judging whether the first monitoring data is less than or equal to a preset monitoring data; when the first monitoring data is greater than the preset monitoring data, confirming that the first monitoring point is in a phosphorus pollution state; obtaining second monitoring data corresponding to a second monitoring point, the second monitoring point is a monitoring point upstream of the target river or target lake and adjacent to the first monitoring point; when the second monitoring data is less than or equal to the preset monitoring data, confirming that the first area is divided to obtain a third monitoring straight line, the first area being the area from the first monitoring straight line corresponding to the first monitoring point to the second monitoring straight line. The area between the second monitoring lines corresponding to the measuring points, the third monitoring line is the monitoring line between the first monitoring line and the second monitoring line; the third monitoring data corresponding to the third monitoring point is obtained, and when the third monitoring data is less than or equal to the preset monitoring data, it is confirmed that the second area is obtained, the third monitoring point is the monitoring point corresponding to any position on the third monitoring line, and the second area is the area between the first monitoring line and the third monitoring line; the isotope ratio information corresponding to the first monitoring point is obtained, and the phosphorus pollution type is determined according to the isotope ratio information. The phosphorus pollution type includes agricultural activity pollution type, urban sewage pollution type and industrial emission pollution type; the target pipeline corresponding to the second area is checked to determine the location information of the phosphorus pollution source, and the phosphorus pollution source location information is sent to the target user. The target pipeline is the pipeline that discharges sewage corresponding to the phosphorus pollution type.

[0007] By adopting the above technical solution, a first monitoring point is set on the surface of a river or lake, and phosphorus monitoring data, i.e., the first monitoring data, can be monitored and obtained in real time. This real-time monitoring method is more efficient than manual sampling. By comparing the first monitoring data with the preset monitoring data, it is possible to automatically determine whether the first monitoring point is in a phosphorus pollution state. Once phosphorus pollution is confirmed, the area that needs further monitoring, i.e., the second area, is automatically divided, and then a new monitoring point, i.e., the third monitoring point, is determined from the second area, thereby narrowing the search range of the pollution source, and obtaining the isotope ratio information of the first monitoring point can further determine the type of phosphorus pollution. This method based on isotope analysis is more accurate and faster than traditional manual analysis, and is helpful to quickly locate possible types of pollution sources. According to the determined type of phosphorus pollution, the target pipeline can be checked in a targeted manner, thereby quickly locating the location of the pollution source. This targeted investigation method is more efficient than manual blind search, and can greatly shorten the tracing time. Once the pollution source location information is confirmed, the relevant information is immediately sent to the target user, and timely feedback helps relevant personnel to take measures quickly to control the spread of pollution.

[0008] Optionally, the type of phosphorus pollution is determined based on the isotope ratio information, specifically including: obtaining preset first water quality information corresponding to the target farmland area, the target farmland area is the farmland area included in the second area; comparing the isotope ratio information with the preset first water quality information; when the isotope ratio information is consistent with the preset first water quality information, it is confirmed that the phosphorus pollution type is the agricultural activity pollution type.

[0009] By adopting the above-mentioned technical scheme, the isotope ratio information can be compared with the preset first water quality information, so as to more accurately determine whether the phosphorus pollution comes from agricultural activities. Once it is confirmed that the type of phosphorus pollution is agricultural activity pollution, the focus of the investigation can be quickly shifted to the target farmland area, narrowing the search scope of the pollution source and improving the traceability efficiency.

[0010] Optionally, the phosphorus pollution type is determined based on the isotope ratio information, specifically including: obtaining preset second water quality information corresponding to the target city treatment plant, the target city treatment plant being the sewage treatment plant contained in the second area; comparing the isotope ratio information with the preset second water quality information; when the isotope ratio information is consistent with the preset second water quality information, confirming that the phosphorus pollution type is the urban sewage pollution type.

[0011] By adopting the above technical solution and comparing the isotope ratio information collected on-site with the preset second water quality information of the target city treatment plant, it is possible to accurately identify whether the phosphorus pollution comes from urban sewage. Once it is confirmed that the phosphorus pollution is urban sewage pollution, the focus of the investigation will be immediately shifted to the target city treatment plant and its surrounding areas, thereby efficiently locating the source of pollution and helping to take quick measures.

[0012] Optionally, the phosphorus pollution type is determined based on the isotope ratio information, specifically including: obtaining the isotope ratio information; judging whether the isotope ratio information exists in a preset phosphorus isotope ratio database, the preset phosphorus isotope ratio database is the isotope ratio information corresponding to the wastewater discharged from the factory in the second area; when the isotope ratio information exists in the preset phosphorus isotope ratio database, it is confirmed that the phosphorus pollution type is the industrial emission pollution type.

[0013] By adopting the above technical solution and comparing the isotope ratio information collected on-site with the information in the preset phosphorus isotope ratio database, it is possible to quickly and accurately identify whether the phosphorus pollution comes from industrial emissions. Once it is confirmed that the type of phosphorus pollution is industrial emission pollution, the focus of the investigation can be immediately shifted to the matching factories in the database to efficiently locate the industrial pollution source.

[0014] Optionally, the target pipeline includes a first pipeline, a second pipeline and a third pipeline, and the target pipeline corresponding to the second area is checked to determine the location information of the phosphorus pollution source, specifically including: if the phosphorus pollution type is an agricultural activity pollution type, the first pipeline is determined according to the agricultural activity pollution type, and the first pipeline is checked to obtain the location information of the phosphorus pollution source, and the first pipeline is a pipeline for discharging wastewater from agricultural activities; if the phosphorus pollution type is an urban sewage pollution type, the second pipeline is determined according to the urban sewage pollution type, and the second pipeline is checked to obtain the location information of the phosphorus pollution source, and the second pipeline is a pipeline for discharging urban wastewater; if the phosphorus pollution type is an industrial emission pollution type, the third pipeline is determined according to the industrial emission pollution type, and the third pipeline is checked to obtain the location information of the phosphorus pollution source, and the third pipeline is a pipeline for discharging industrial wastewater.

[0015] By adopting the above technical solution and determining the specific emission pipeline according to the type of phosphorus pollution, the scope of pollution source investigation can be greatly narrowed, the efficiency and accuracy of investigation can be improved, which will help to quickly locate the pollution source, reduce unnecessary investigation work, and save time and resources.

[0016] Optionally, before determining the location information of the phosphorus pollution source, the method also includes: obtaining fourth monitoring data corresponding to the target pipeline; if the fourth monitoring data is greater than the preset monitoring data, confirming the target position corresponding to the target pipeline, and outputting the target position as the location information of the phosphorus pollution source.

[0017] By adopting the above technical solution, monitoring the water quality data in the target pipeline, i.e., the fourth monitoring data, and comparing the fourth monitoring data with the preset monitoring data, the location where the pollution occurs can be accurately determined. Once the pollution location is confirmed, corresponding measures can be taken immediately, which helps to improve the overall level of environmental management.

[0018] Optionally, after checking the target pipeline corresponding to the second area, determining the location information of the phosphorus pollution source, and sending the location information of the phosphorus pollution source to the target user, the method also includes: determining control measures based on the target concentration data, the control measures include first control measures and second control measures; when the target concentration data is less than or equal to the preset concentration data, confirming the adoption of the first control measure, the first control measure includes biological treatment measures and adsorption treatment measures; when the target concentration data is greater than the preset concentration data, confirming the adoption of the second control measure, the second control measure includes chemical precipitation measures, membrane separation treatment measures and enhanced sludge treatment measures.

[0019] By adopting the above technical scheme and selecting treatment measures according to the actual concentration of pollutants, unnecessary waste of resources can be avoided. When the pollutant concentration is low, relatively economical and environmentally friendly methods such as biological treatment measures and adsorption treatment measures can be used to reduce the treatment cost while ensuring the treatment effect; when the pollutant concentration is high, a more effective second treatment measure, such as chemical precipitation, membrane separation and enhanced sludge treatment, can be used to quickly reduce the pollutant concentration, prevent the spread of pollution, and protect the environment and human health.

[0033] In order to enable technicians in this field to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification.

[0036] With the acceleration of industrialization and urbanization, environmental problems are becoming more and more serious. Among them, water pollution has become a key bottleneck restricting the sustainable development of rivers. Phosphorus, as an indispensable nutrient element in aquatic ecosystems, is excessively present and is the main cause of eutrophication of water bodies. Eutrophication causes abnormal proliferation of algae, consumes a large amount of dissolved oxygen, and threatens the living space of other aquatic organisms, seriously disrupting the natural balance of aquatic ecosystems.

[0037] In order to accurately assess the current status and dynamic changes of phosphorus pollution in rivers and lakes, scientific phosphorus content testing is required. However, understanding the current status of pollution alone is not enough to fully respond to environmental challenges, and in-depth tracing of the sources of phosphorus pollution is also crucial. Given that different pollution sources contribute differently to the phosphorus load in water bodies and targeted governance measures need to be taken, it is particularly important to conduct a detailed source tracing analysis of phosphorus pollution. At present, although the phosphorus pollution status of rivers and lakes can be confirmed through water quality testing, the tracing process still mainly relies on traditional methods of manual on-site investigations and sampling analysis. This method is inefficient and cannot obtain pollution source information in a timely manner.

[0038] Therefore, how to effectively solve the problem of low sampling efficiency and inability to obtain pollution source information in a timely manner when manually tracing the source of phosphorus pollution in rivers and lakes. The embodiment of the present application provides a method for tracing the source of phosphorus pollution in rivers and lakes, which is applied to a server. The server of the present application can be a platform that provides phosphorus pollution tracing services for rivers and lakes. Figure 1 This is a flow chart of a method for tracing the source of phosphorus pollution in rivers and lakes provided in an embodiment of the present application, with reference to Figure 1 The method includes the following steps S101-S108.

[0039] S101: Acquire first monitoring data corresponding to a first monitoring point, where the first monitoring point is any monitoring point set on the surface of a target river or a target lake.

[0040] In the above S101, first, in order to better confirm that the target river or target lake is in a phosphorus-polluted area, the surface of the target river or target lake can be divided into regions, and each region uses a monitoring line as a dividing boundary, and then phosphorus pollution monitoring is performed on any monitoring point on each monitoring line in turn. At this time, any monitoring point on the first monitoring line can be used as the first monitoring point, and the first monitoring line is any monitoring line among multiple monitoring lines. The first monitoring point is randomly selected on the first monitoring line, or it can be selected based on a certain strategy, such as selecting a position in the middle of the monitoring line or a position on both sides. A dedicated phosphorus monitoring device or sensor can be used to sample and analyze at the first monitoring point to obtain phosphorus concentration data, i.e., the first monitoring data.

[0041] S102: Determine whether the first monitoring data is less than or equal to the preset monitoring data.

[0042] In the above S102, after obtaining the first monitoring data, it is determined whether the first monitoring data is less than or equal to the preset monitoring data, which is usually a safety threshold set according to environmental protection standards and historical data. The first monitoring data is compared with the preset monitoring data to determine whether the phosphorus content in the water quality of the first monitoring point exceeds the standard.

[0043] S103: When the first monitoring data is greater than the preset monitoring data, it is confirmed that the first monitoring point is in a phosphorus pollution state.

[0044] In the above S103, when the first monitoring data is greater than the preset monitoring data, it is confirmed that the first monitoring point is in a phosphorus pollution state, and the first monitoring point needs to be immediately marked as a phosphorus pollution state. When it is confirmed that the first monitoring point in the target river or target lake is in a phosphorus pollution state, the cause of the phosphorus pollution needs to be traced to determine the source of the phosphorus pollution that causes the water quality of the target river or target lake to be in a phosphorus pollution state.

[0045] S104: Acquire second monitoring data corresponding to a second monitoring point, where the second monitoring point is a monitoring point upstream of a target river or a target lake and adjacent to the first monitoring point.

[0046] In the above S104, after determining the position of the first monitoring point in the target river, since the water in the target river and the target lake flows from upstream to downstream, after determining the position of the first monitoring point in the target river, it is necessary to select a monitoring point that is upstream of the target river or the target lake and is adjacent to the first monitoring point, i.e., the second monitoring point. After determining the second monitoring point, the phosphorus monitoring equipment is used to perform sampling and analysis at the second monitoring point to obtain the second monitoring data. Figure 2 As shown, the target river can be divided, and each area corresponds to a monitoring line. When the first monitoring point is selected from the monitoring line A, if it is confirmed that the first monitoring point is in a phosphorus pollution state, it is necessary to monitor the upstream of the first monitoring point in turn, and then the source of phosphorus pollution can be found. In the figure, the monitoring line E is downstream of the first monitoring point, so the second monitoring point is not selected from the monitoring line E, but from the upstream of the first monitoring point. However, there are multiple monitoring lines upstream of the first monitoring point. In order to narrow the search range, other monitoring points that are adjacent to the first monitoring point can be obtained as the second monitoring point, and the second monitoring point can be judged. At this time, the second monitoring point is selected from the monitoring line B. Although the monitoring lines C and D are upstream of the first monitoring point, they are not adjacent to the first monitoring point.

[0047] S105: When the second monitoring data is less than or equal to the preset monitoring data, it is confirmed that the first area is divided to obtain a third monitoring line.

[0048] In the above S105, it is determined whether the second monitoring data is less than or equal to the preset monitoring data. When the second monitoring data is less than or equal to the preset monitoring data, it means that the phosphorus data of the second monitoring point is not exceeded, indicating that phosphorus pollution occurs in the area between the first monitoring point and the second monitoring point. The first area is determined according to the first monitoring line corresponding to the first monitoring point and the second monitoring line corresponding to the second monitoring point, and then the first area is divided to obtain the third monitoring line. The third monitoring line is a monitoring line located between the first monitoring line and the second monitoring line. The middle can represent the middle position of the first area, that is, the position where the first area is divided equally, and can also represent the division of the first area in other proportions. The specific meaning of the corresponding position can be selected based on the actual situation, and no excessive restrictions are made here.

[0049] S106: Acquire third monitoring data corresponding to the third monitoring point, and when the third monitoring data is less than or equal to the preset monitoring data, confirm that the second area is acquired.

[0050] In the above S106, any position is selected from the third monitoring line as the third monitoring point, and then the phosphorus monitoring equipment is used to sample and analyze at the third monitoring point to obtain the third monitoring data. The third monitoring data is compared with the preset monitoring data. When the third monitoring data is less than or equal to the preset monitoring data, it means that the phosphorus pollution is more likely to be concentrated in the area between the first monitoring line and the third monitoring line, and the area between the first monitoring line and the third monitoring line is located as the second area. The range corresponding to the second area can be determined on the map of the target river or target lake.

[0051] S107: Obtain isotope ratio information corresponding to the first monitoring point, and determine the type of phosphorus pollution according to the isotope ratio information.

[0052] In the above S107, different isotope ratios will be caused by phosphorus pollution from different sources (such as agricultural activities, urban sewage and industrial emissions). The isotope ratio of phosphorus pollution at the first monitoring point can be determined by isotope analysis technology, and the isotope ratio information is output. The obtained isotope ratio information is compared with the known isotope ratio to determine the type of phosphorus pollution. Since phosphorus pollution types include agricultural activity pollution types, urban sewage pollution types and industrial emission pollution types. Next, how to determine the type of phosphorus pollution based on the isotope ratio information is introduced in turn.

[0053] The first confirmation method is to determine the type of phosphorus pollution based on the isotope ratio information, which specifically includes: obtaining the preset first water quality information corresponding to the target farmland area, and the target farmland area is the farmland area included in the second area; comparing the isotope ratio information with the preset first water quality information; when the isotope ratio information is consistent with the preset first water quality information, the phosphorus pollution type is confirmed to be the agricultural activity pollution type. Specifically, after determining that the second area is an area with phosphorus pollution, first clarify the scope of the second area, and then clarify whether there is a farmland area around the second area. The surrounding area can be understood as the shore of a river or lake. If there is a farmland part on the shore of the second area, the farmland part is located as the target farmland area. Water quality information of the target farmland area can be collected through historical monitoring data, farmland irrigation water quality reports, or water quality assessments by professional institutions. These water quality information should include indicators related to phosphorus pollution, such as phosphorus concentration, isotope ratio, etc. According to the collected farmland water quality data, combined with the characteristics of farmland activities (such as fertilizer use, pesticide residues, etc.), one or more water quality index thresholds or isotope ratio ranges related to farmland activities are set as the preset first water quality information. In the previous step, the phosphorus pollution isotope ratio information of the first monitoring point (located in a river or lake) was obtained by isotope analysis technology. The obtained isotope ratio information is compared with the isotope ratio range in the preset first water quality information. If the isotope ratio information is consistent with or highly similar to the isotope ratio range in the preset first water quality information, it can be preliminarily determined that the phosphorus pollution comes from farmland activities. In addition to the isotope ratio information, the use of fertilizers, pesticide residues, farmland drainage systems, etc. in the farmland area can also be investigated to confirm the type of phosphorus pollution. Based on comprehensive consideration of the isotope ratio information and other evidence, the phosphorus pollution type is finally confirmed to be the agricultural activity pollution type.

[0054] The second confirmation method is to determine the type of phosphorus pollution based on the isotope ratio information, which specifically includes: obtaining the preset second water quality information corresponding to the target city treatment plant, the target city treatment plant is the sewage treatment plant included in the second area; comparing the isotope ratio information with the preset second water quality information; when the isotope ratio information is consistent with the preset second water quality information, it is confirmed that the phosphorus pollution type is the urban sewage pollution type. Specifically, after determining that the second area is an area with phosphorus pollution, first clarify the scope of the second area, and then clarify whether there is a living area around the second area. The sewage generated in the living area will be discharged by the urban sewage treatment plant. If there is a living area in the second area, the location information corresponding to the urban sewage treatment plant can be obtained first, and the urban sewage treatment plant with the location information in the second area can be obtained, and the sewage treatment plant is used as the target city treatment plant. Obtain historical monitoring data on the effluent water quality from the target city treatment plant, especially indicators related to phosphorus pollution, such as phosphorus concentration, isotope ratio, etc. These data may be monitored by the sewage treatment plant itself and reported to the environmental protection department, or monitored by a third-party agency. According to the collected water quality data of sewage treatment plants, combined with the characteristics and treatment process of urban sewage, one or more water quality index thresholds or isotope ratio ranges related to urban sewage are set as the preset second water quality information. These thresholds or ranges should be able to reflect the characteristics of phosphorus pollution that may remain after urban sewage is treated. In the previous steps, the isotope ratio information of phosphorus pollution in rivers or lakes has been obtained by isotope analysis technology. This information is obtained by analyzing the phosphorus isotope composition in the polluted water body. Compare the obtained isotope ratio information with the isotope ratio range in the preset second water quality information. This step requires precise isotope analysis technology and professional comparison methods to ensure the accuracy of the results. If the isotope ratio information is highly consistent or similar to a range in the preset second water quality information, it may indicate that the phosphorus pollution comes from urban sewage. In addition to the isotope ratio information, other evidence can also be combined to further confirm the type of phosphorus pollution. For example, investigate the operating status of the treatment plant in the target city, the compliance of the effluent water quality, and whether the treatment process is perfect. At the same time, factors such as the population density, urbanization level, and industrial layout of cities around rivers or lakes can also be considered to determine whether there is a possibility of urban sewage discharge. Based on a comprehensive consideration of the isotope ratio information and other evidence, it is finally confirmed whether the phosphorus pollution type is the urban sewage pollution type. If the isotope ratio information is consistent with the preset second water quality information, and other evidence also supports the possibility of urban sewage as a pollution source, the phosphorus pollution type can be confirmed as the urban sewage pollution type.

[0055] The third confirmation method is to determine the type of phosphorus pollution based on the isotope ratio information, which specifically includes: obtaining isotope ratio information; judging whether there is isotope ratio information in the preset phosphorus isotope ratio database, and the preset phosphorus isotope ratio database is the isotope ratio information corresponding to the wastewater discharged from the factory in the second area; when the isotope ratio information exists in the preset phosphorus isotope ratio database, the phosphorus pollution type is confirmed to be an industrial discharge pollution type. Specifically, first determine whether there is a factory in the second area. If there is a factory in the second area, the isotope ratio information corresponding to the first monitoring point can be obtained, and the isotope ratio information can be entered into the preset phosphorus isotope ratio database for matching. The preset phosphorus isotope ratio database is a database containing the isotope ratio information corresponding to the wastewater discharged from the factory in the second area. The database contains key information such as the isotope ratio data of the wastewater discharged by each factory, the factory name, the location of the discharge port, and the discharge time. The obtained isotope ratio information is compared and matched with the data in the preset phosphorus isotope ratio database. Professional data analysis software or algorithms can be used to realize automatic comparison and matching of data to improve efficiency and accuracy. According to the comparison and matching results, it is determined whether there is data in the preset phosphorus isotope ratio database that is consistent or highly similar to the obtained isotope ratio information. If there is consistent or highly similar data, it indicates that the isotope ratio information may come from wastewater discharged by one or more factories in the second area. According to the comparison results, the phosphorus pollution type is finally determined to be an industrial emission pollution type.

[0056] S108: Check the target pipeline corresponding to the second area, determine the location information of the phosphorus pollution source, and send the location information of the phosphorus pollution source to the target user.

[0057] In the above S108, based on the determined phosphorus pollution type, the pipelines that may discharge pollutants (such as agricultural irrigation pipelines, urban sewage pipelines, industrial discharge pipelines) are locked, and the target pipelines in the second area are checked one by one to find possible leakage points or discharge outlets. The target pipeline is a pipeline that discharges sewage corresponding to the phosphorus pollution type.

[0058] In addition, how to determine different wastewater discharge pipelines according to the type of phosphorus pollution, and check the corresponding pipelines to obtain the location information of the phosphorus pollution source. The target pipelines include the first pipeline, the second pipeline and the third pipeline. The target pipelines corresponding to the second area are checked to determine the location information of the phosphorus pollution source. Specifically, if the phosphorus pollution type is agricultural activity pollution type, the first pipeline is determined according to the agricultural activity pollution type, and the first pipeline is checked to obtain the location information of the phosphorus pollution source. The first pipeline is the pipeline for discharging farmland activity wastewater; if the phosphorus pollution type is urban sewage pollution type, the second pipeline is determined according to the urban sewage pollution type, and the second pipeline is checked to obtain the location information of the phosphorus pollution source. The second pipeline is the pipeline for discharging urban wastewater; if the phosphorus pollution type is industrial emission pollution type, the third pipeline is determined according to the industrial emission pollution type, and the third pipeline is checked to obtain the location information of the phosphorus pollution source. The third pipeline is the pipeline for discharging industrial wastewater. Specifically, first collect water quality monitoring data of suspected polluted areas, including key indicators such as phosphorus concentration and isotope ratio. By analyzing data and isotope traceability analysis technology and other methods, the pollution type of phosphorus pollution is determined. According to the analysis results, phosphorus pollution types are divided into three types: farmland activity pollution, urban sewage pollution and industrial emission pollution. Each type of pollution has its own specific characteristics and indicators. For example, farmland activity pollution may be accompanied by the discharge of pollutants such as pesticides and fertilizers; urban sewage pollution may contain high concentrations of domestic sewage components; and industrial emission pollution may contain specific industrial wastewater components and isotope ratios. If the phosphorus pollution type in the second area is determined to be agricultural activity pollution, the pipeline (first pipeline) for discharging agricultural activity wastewater is determined based on information such as farmland distribution, irrigation system, and drainage channels. The first pipeline is usually connected to the irrigation system and drainage system of the farmland, and is used to discharge farmland irrigation, rainwater runoff, and wastewater that may contain pollutants such as pesticides and fertilizers. If the phosphorus pollution type in the second area is determined to be urban sewage pollution, the pipeline (second pipeline) for discharging urban wastewater is determined based on information such as the urban drainage system and the distribution of sewage treatment plants. The second pipeline is usually connected to the urban drainage network, and is used to collect and treat urban domestic sewage and some industrial wastewater. If the phosphorus pollution type in the second area is industrial emission pollution type, the pipeline for discharging industrial wastewater (the third pipeline) shall be determined based on information such as industrial layout and factory wastewater discharge outlets. The third pipeline is usually connected to the factory's wastewater treatment facilities and discharge outlets, and is used to discharge treated or untreated industrial wastewater. According to the determined discharge pipeline, a detailed investigation plan shall be formulated. According to the investigation plan, the determined discharge pipelines shall be investigated one by one. During the investigation, attention should be paid to the direction, interfaces, leakage points and other locations where pollutants may leak. Use professional testing equipment and instruments, such as water quality monitors, isotope analyzers, etc., to sample and analyze the wastewater in the pipeline. According to the data and samples collected during the investigation, analyze the source, concentration, isotope ratio and other information of the pollutants.The specific location of the pollution source is determined by combining on-site investigation and isotope tracing and analysis technology.

[0059] Further, after determining the target pipeline according to the type of phosphorus pollution, the monitoring data in the target pipeline is judged, and the location information of the phosphorus pollution source is determined based on the judgment result, specifically including: obtaining the fourth monitoring data corresponding to the target pipeline; if the fourth monitoring data is greater than the preset monitoring data, confirming the target location corresponding to the target pipeline, and outputting the target location as the location information of the phosphorus pollution source. Specifically, based on the relevant buildings or facilities existing around the second area, the type of phosphorus pollution is determined, and then the target pipeline is determined according to the type of phosphorus pollution. When the phosphorus pollution type is agricultural activity pollution type, the target pipeline is the first pipeline; when the phosphorus pollution type is urban sewage pollution type, the target pipeline is the second pipeline; when the phosphorus pollution type is industrial emission pollution type, the target pipeline is the third pipeline. Water quality monitoring equipment is installed at key locations of the target pipeline (such as inlet, outlet, branch point, etc.). These devices should have the function of real-time monitoring of water quality parameters (such as phosphorus concentration). Start the monitoring equipment and start collecting water quality monitoring data of the target pipeline. These data will serve as the basis for subsequent analysis and judgment. Process and analyze the collected monitoring data to extract the fourth monitoring data related to the target pipeline. This may include key parameters such as phosphorus concentration, flow rate, and flow rate. The fourth monitoring data is compared with the preset detection data. If the fourth monitoring data is greater than the preset monitoring data, it indicates that there may be problems with the water quality in the target pipeline, and the target position corresponding to the target pipeline is obtained. After the target position is confirmed, it can be output as the location information of the phosphorus pollution source. This usually includes information such as location description, exceeding parameters, and degree of exceeding. According to the output phosphorus pollution source location information, take corresponding countermeasures. This may include measures such as strengthening monitoring, restricting emissions, and repairing pipelines to reduce or eliminate the impact of phosphorus pollution on the environment and human health. After confirming the location information of the phosphorus pollution source, the phosphorus pollution source location information is sent to the target user. At this time, the target user may be an environmental protection department, a local government, a related enterprise, etc. The pollution source location information is promptly notified to the target user by email, text message, telephone or other means of communication so that they can take further countermeasures.

[0060] In a possible implementation, phosphorus pollution control measures can be determined according to the target concentration data, specifically including: determining control measures according to the target concentration data, the control measures include the first control measures and the second control measures; when the target concentration data is less than or equal to the preset concentration data, it is confirmed that the first control measures are taken, and the first control measures include biological treatment measures and adsorption treatment measures; when the target concentration data is greater than the preset concentration data, it is confirmed that the second control measures are taken, and the second control measures include chemical precipitation measures, membrane separation treatment measures, and enhanced sludge treatment measures. Specifically, in waters suspected of being contaminated by phosphorus or near discharge ports, water samples are collected according to the prescribed sampling method and frequency. Use professional water quality monitoring instruments or laboratory analysis methods to measure the phosphorus concentration of the collected water samples to obtain target concentration data. The measured target concentration data is obtained, and then the target concentration data is compared with the preset phosphorus concentration data to determine the degree of pollution. According to the comparison result of the target concentration data and the preset concentration data, the severity of phosphorus pollution is judged. If the target concentration data is less than or equal to the preset concentration data, it means that the pollution level is relatively light, and a milder first control measure can be taken. The first treatment measures include biological treatment measures and adsorption treatment measures. Biological treatment measures use the metabolism of microorganisms to convert phosphorus in water into harmless or low-toxic substances. This usually includes activated sludge method, biofilm method, etc. Adsorption treatment measures use materials with adsorption capacity (such as activated carbon, zeolite, etc.) to adsorb phosphorus in water to the surface of the material, so as to achieve the purpose of removing phosphorus. If the target concentration data is greater than the preset concentration data, it means that the pollution level is serious and more stringent second treatment measures need to be taken. The second treatment measures include chemical precipitation measures, membrane separation treatment measures and enhanced sludge treatment measures. Chemical precipitation measures are to add chemical reagents (such as iron salts, aluminum salts, etc.) to water to make phosphorus react with the reagents to form water-insoluble precipitates, and then remove the precipitates from the water by precipitation, filtration, etc. Membrane separation treatment measures use membrane technology (such as ultrafiltration, nanofiltration, reverse osmosis, etc.) to separate and remove phosphorus in water. This method usually has the advantages of high efficiency, energy saving, and environmental protection. Strengthening sludge treatment measures means that the sludge generated during the treatment process may contain a high phosphorus content. Therefore, it is necessary to strengthen the treatment and disposal of sludge to prevent the phosphorus in the sludge from being released into the environment again. This usually includes steps such as dehydration, stabilization, and resource utilization of sludge. The target river or lake is treated according to the selected treatment measures. During the treatment process, the water quality changes should be closely monitored and the treatment measures and parameters should be adjusted in time. After the treatment work is completed, the water quality is monitored and evaluated again. Compare the water quality data before and after the treatment to determine the effectiveness of the treatment measures.
