[0040] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] Below, the water pollution tracing method and device provided in the embodiments of the present application will be introduced and explained in detail through several specific embodiments.

[0042] In one embodiment, a method for tracing the source of water pollution is provided, which is applied to a server and is used to trace the source of water pollution collected by each monitoring device in the target area to a monitoring terminal. The server can be an independent server or a server cluster composed of multiple servers, and can also be a cloud server that provides basic cloud computing services such as cloud services, cloud message databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and large message data and artificial intelligence sampling point devices.

[0043] like Figure 1 As shown, a method for tracing the source of water pollution provided in this embodiment includes:

[0044] Step 101, in response to an alarm signal indicating that the concentration of a target pollutant in water quality in a target area is abnormal, determining the pollution contribution concentration of each water flow path according to the amount of target pollutants flowing into each water flow path flowing into the target area and the total water storage volume of the target area;

[0045] Step 102, determining at least one target water flow path where the pollution contribution concentration reaches a preset concentration from each of the water flow paths;

[0046] Step 103, obtaining pollution source tracing results according to the water pollution concentration uploaded by each monitoring station in the target water flow path.

[0047] In some embodiments, the target area may be any water storage area that needs to be monitored for water quality, such as a water storage area of ​​a reservoir. The target area may be provided with sensing equipment for monitoring the water flow in the target area, such as a water quality monitor for monitoring water quality and a water quantity monitor for monitoring water quantity. The water flow converging to the target area has multiple tributaries, that is, multiple water flow paths. The confluence of each water flow path into the target area may also be provided with a sensing equipment for monitoring the water flow, so as to monitor the water quality and water quantity, etc., converging into the target area through the water flow path.

[0048] Any water flow path can divide the area where the water flows into multiple areas according to the direction of the water flow. For example, the water flow path can be divided into multiple waterways, each of which represents an area. The size of each area can be set according to actual conditions. Each area is equipped with at least one monitoring station for monitoring water quality, such as a water quality monitor for monitoring water quality.

[0049] For example, Figure 2 As shown, multiple water flow paths 10 converge into a target area 20, and each water flow path can be divided into multiple areas 30. The size and shape of each area 30 can be set according to actual conditions. For example, the area 30 can be a certain section of water on the water flow path 10. The target area 20 can be provided with a sensing device for monitoring the water flow in the target area, and the confluence of each water flow path into the target area can also be provided with a sensing device for monitoring the water flow. Each area 30 is provided with at least one monitoring station for monitoring water quality.

[0050] The server can receive monitoring data of water flow in the target area uploaded by the sensing device in the target area, such as pollutant concentration or water storage capacity. The server can pre-set any pollutant as a target pollutant, such as phosphorus, nitrogen or permanganate. When the server detects that the concentration of a target pollutant in the monitoring data uploaded by the sensing device reaches the concentration threshold, such as the concentration of permanganate reaches the concentration threshold, it means that the concentration of the target pollutant is abnormal. At this time, an alarm signal is generated to indicate that the concentration of the target pollutant in the water quality in the target area is abnormal. Among them, the preset concentration can be set according to the actual situation.

[0051] After the alarm signal is generated, the target pollutant inflow amount of each water flow path into the target area can be obtained through the sensing device set at the inlet where each water flow path flows into the target area in response to the alarm signal. For example, the target pollutant concentration uploaded by the sensing device and the total amount of water flow flowing into the water flow path can be obtained through the sensing device set at the inlet where a certain water flow path flows into the target area, so as to determine the target pollutant inflow amount of the water flow path into the target area based on the target pollutant concentration and the total amount of water flow.

[0052] After obtaining the target pollutant inflow amount of a certain water flow path into the target area, the pollution contribution concentration of the water flow path can be obtained based on the target pollutant inflow amount and the total water storage amount of the target area obtained by the sensing equipment in the target area. For example, pollution contribution concentration = target pollutant inflow amount / total water storage amount.

[0053] After obtaining the pollution contribution concentration of each water flow path, the pollution contribution concentration of each water flow path can be compared with the preset concentration. The preset concentration can be set according to the actual situation. For example, the preset concentration can be determined according to the critical concentration that causes the abnormal concentration of the target pollutant. The critical concentration that causes the abnormal concentration of the target pollutant can be used as the preset concentration. The critical concentration means that if the concentration of the target pollutant reaches the critical concentration, it will cause the concentration of the target pollutant to be abnormal.

[0054] If the pollution contribution concentration of the water flow path does not reach the preset concentration, it means that the water flow in the water flow path is not the pollution source that causes the abnormal concentration of the target pollutant in the water quality in the target area, so the water flow path can be ignored; if the pollution contribution concentration of the water flow path reaches the preset concentration, it means that the water flow path may be the pollution source that causes the abnormal concentration of the target pollutant in the water quality in the target area. For example, when the preset concentration is the critical concentration that causes the abnormal concentration of the target pollutant, if the pollution contribution concentration of the water flow path reaches the preset concentration, it means that the water flow in the water flow path merges into the target area, which will cause the abnormal concentration of the target pollutant in the water quality in the target area. At this time, it can be determined that the water flow path is the pollution source that causes the abnormal concentration of the target pollutant in the water quality in the target area, so that the water flow path is determined as the target water flow path.

[0055] After determining the target water flow path, the water quality data uploaded by each monitoring station in the target water flow path can be obtained to extract the concentration of the target pollutant monitored by each monitoring station from the water quality data uploaded by each monitoring station. After obtaining the target pollutant concentration monitored by each monitoring station in the target water flow path, the pollution source of the target pollutant can be determined from the area corresponding to each monitoring station based on the target pollutant concentration monitored by each monitoring station. The pollution source is the pollution tracing result. For example, the area corresponding to the monitoring station with the highest concentration of the target pollutant can be determined as the area where the pollution source is located to achieve pollution tracing.

[0056] By responding to the alarm signal indicating that the concentration of target pollutants in the water quality in the target area is abnormal, the pollution contribution concentration of each water flow path is determined according to the amount of target pollutants flowing into each water flow path flowing into the target area and the total water storage in the target area, and at least one target water flow path whose pollution contribution concentration reaches the preset concentration is determined from each water flow path, so as to obtain the pollution source tracing result according to the target pollutant concentration uploaded by each monitoring station in the target water flow path. Thus, the water flow path that causes water pollution in the target area can be determined from multiple water flow paths, and the water quality data uploaded by the monitoring station of the water flow path that causes water pollution can be used to trace the pollution source, so that the pollution source of water quality can be traced without checking the monitoring stations of all water flow paths, thereby improving the pollution source tracing efficiency of water quality.

[0057] To improve the accuracy of pollution source tracing, in some embodiments, the preset concentration may be determined as follows:

[0058] Determine the initial concentration based on the critical concentration that causes abnormal concentration of target pollutants;

[0059] The preset concentration is determined according to the initial concentration and the number of each of the water flow paths.

[0060] Considering that the target pollutant concentration in the target area is abnormal, it may be the result of the convergence of target pollutants from multiple water flow paths, and the target pollutant concentration of a single water flow path may not cause the target pollutant concentration in the target area to be abnormal. Therefore, if the critical concentration that causes the abnormal concentration of the target pollutant is determined as the preset concentration, it may be impossible to find the target water flow path, resulting in the inability to trace the pollution source. To this end, in some embodiments, the critical concentration that causes the abnormal concentration of the target pollutant can be first determined as the initial concentration, and then the initial concentration can be divided by the number of water flow paths that flow into the target area to obtain the preset concentration. Since the preset concentration is the initial concentration, that is, the critical concentration / the number of water flow paths that flow into the target area, and the pollutant concentration of the water quality in the target area is affected by the water flow that flows into each water flow path, when the target pollutant concentration of the water quality in the target area is abnormal, there must be at least one water flow path whose pollution contribution concentration reaches the preset concentration. In this way, it is possible to avoid the situation where the target water flow path cannot be found, resulting in the inability to trace the pollution source, thereby improving the accuracy of pollution tracing.

[0061] If the pollution contribution concentration of a certain water flow path does not reach the preset concentration, it means that the water flow from this water flow path into the target area is not the main factor causing the abnormal target pollutant concentration of the water quality in the target area, and the water flow path can be ignored at this time; if the pollution contribution concentration of a water flow path reaches the preset concentration, it means that the water flow from this water flow path into the target area is the main factor causing the abnormal target pollutant concentration of the water quality in the target area, and the water flow path can be determined as the target water flow path.

[0062] After determining the target water flow path, for any target water flow path, the pollution source of the target pollutant can be determined from the area corresponding to each monitoring station according to the target pollutant concentration monitored by each monitoring station in the target water flow path, so as to obtain the pollution source tracing result. Considering that there may be multiple pollution sources, in addition to determining the area corresponding to the monitoring station with the highest target pollutant concentration as the pollution source corresponding to the target pollutant, if the target pollutant concentration of the monitoring station reaches the preset concentration, it means that the water flow in the area where the monitoring station is located will cause the target pollutant concentration in the target area to be abnormal, so the area where the monitoring station in the target water flow path is located where the target pollutant concentration is greater than the above preset concentration can be determined as the area where the pollution source is located.

[0063] Considering that the areas where the monitoring stations are located have an upstream and downstream relationship, the water flow in the upstream area will flow into the downstream area, so that the water quality in the downstream area will be affected by the water quality in the upstream area. Therefore, the abnormal concentration of target pollutants in a certain area may be affected by the water flow in its upstream area, and there is no pollution source in itself. Therefore, in order to further improve the accuracy of pollution tracing, in some embodiments, such as Figure 3As shown, according to the target pollutant concentrations uploaded by each monitoring station in the target water flow path, the pollution source tracing results are obtained, including:

[0064] Step 201, according to the target pollutant concentration uploaded by each monitoring station in the target water flow path, determine each abnormal station where the target pollutant concentration reaches the preset concentration from each monitoring station;

[0065] Step 202, determining the pollution contribution of the abnormal site according to the difference between the target pollutant concentration of the abnormal site and the target pollutant concentration of the upstream monitoring site adjacent to the abnormal site;

[0066] Step 203, obtaining the pollution source tracing result according to the pollution contribution of each abnormal site.

[0067] In some embodiments, after determining the target water flow path, the target pollutant concentration uploaded by each monitoring station can be extracted from the water quality data uploaded by each monitoring station in the water flow path. After obtaining the target pollutant concentration uploaded by each monitoring station, the monitoring station whose target pollutant concentration reaches the preset concentration is determined as an abnormal station.

[0068] If there is only one abnormal site, the area where the abnormal site is located can be determined as the area where the pollution source is located to complete the pollution source tracing.

[0069] If there are multiple abnormal sites, then for any abnormal site, the monitoring site in the upstream area adjacent to the area where the abnormal site is located will be determined as the upstream monitoring site adjacent to the abnormal site, and the target pollutant concentration uploaded by the upstream monitoring site will be obtained, so as to subtract the pollutant concentration of the upstream monitoring site from the target pollutant concentration of the abnormal site to obtain the target pollutant concentration of the abnormal site and the difference between the pollutant concentration of the upstream monitoring site will be used as the pollution contribution of the abnormal site.

[0070] After obtaining the pollution contribution of each abnormal station, the area where the abnormal station with the highest pollution contribution is located can be determined as the area where the pollution source is located to obtain the pollution source tracing result. In this way, the misjudgment of the pollution source can be reduced and the accuracy of pollution source tracing can be improved.

[0071] Considering that there may be more than one area with pollution sources, in order to further improve the accuracy of pollution source tracing, in some embodiments,

[0072] According to the pollution contribution of each abnormal site, the pollution source tracing result is obtained, including:

[0073] Determine, from among the abnormal sites, a target site whose pollution contribution is greater than a preset contribution;

[0074] The pollution source tracing result is obtained according to the area where the target site is located.

[0075] In some embodiments, after obtaining the pollution contribution of each abnormal site, the abnormal site whose pollution contribution is greater than the preset contribution can be determined as the target site, so that the area where the target site is located can be determined as the area where the pollution source is located. Among them, the preset contribution can be set according to the actual situation. Exemplarily, the preset contribution can be set to 0. If the pollution contribution of the target site is greater than 0, it means that there is an increase in pollutants in the area where the target site is located. At this time, the area where the target site is located can be determined as the area where the pollution source is located. In addition, the preset contribution can also be set to other values, such as the critical concentration that causes the abnormal concentration of the target pollutant. At this time, if the pollution contribution of the target site is greater than the critical concentration, it means that there is pollution in the area where the target site is located. At this time, the area where the target site is located can be determined as the area where the pollution source is located.

[0076] In order to further improve the accuracy of pollution source tracing, in some embodiments, the pollution source tracing result is obtained according to the area where the target site is located, including:

[0077] According to the area where the target site is located, determine the pollution source corresponding to the area where the target site is located from the water pollution knowledge graph;

[0078] Among them, the water pollution knowledge graph is generated based on the location information and pollution sources of the areas where each of the monitoring stations is located.

[0079] In some embodiments, the server may form a traceability network representing the upstream and downstream relationship of each area based on the location information of the area where the monitoring stations of each water flow path are located, and then for any monitoring station, the pollution source of the area where the monitoring station is located may be recorded in advance. Among them, the pollution source of the area where a certain monitoring station is located may be determined based on the environmental information of the area where the monitoring station is located. For example, for area A, if there is a factory within its preset range, the pollution source of area A may be recorded as industrial pollution; for area B, if there is farmland within its preset range, the pollution source of area B may be recorded as agricultural pollution, etc. After determining the pollution source corresponding to each area, the pollution source corresponding to each area and the traceability network representing the upstream and downstream relationship of each area may be combined to form a water pollution knowledge graph.

[0080] After determining the target site whose pollution contribution is greater than the preset contribution, the pollution source corresponding to the area where the target site is located can be found from the water pollution knowledge graph according to the area where the target site is located, as the pollution source tracing result. In this way, the water pollution knowledge graph can be used to more accurately determine the pollution source that causes the abnormal concentration of the target pollutant in the water quality in the target area.

[0081] The water quality pollution source tracing device provided in the present application is described below. The water quality pollution source tracing device described below and the water quality pollution source tracing method described above can be referenced to each other.
