Wherein the target site is associated with the target contamination source geographical location and the target site is associated with at least one of the target contamination sources.
Specifically, the pollution source may be an enterprise, a discharge port, or the like that generates pollutants and causes water pollution to a target site. According to the scheme, the pollution source within a certain range from the target site can be determined as the target pollution source, and the pollution source positioned at the upstream of the target site can also be determined as the target pollution source.

Fig. 2 is a flowchart of a tracing method of water pollution according to an embodiment of the present invention, and the embodiment is optimized based on the above embodiment. As shown in fig. 2, the tracing method of water pollution in the embodiment of the present invention may include:
and S210, if the water quality exceeding information is received, determining the target site which acquires the water quality exceeding information.
In this embodiment, optionally, the method further includes: correspondingly displaying the water quality information of the target site on a map by adopting a GIS technology according to the corresponding relation between the pre-stored water quality grade and the water quality icon; wherein the target site is associated with a water quality rating.
Specifically, the water quality information may be water quality grades, such as first-class water quality and second-class water quality. The corresponding relation between the water quality grade and the water quality icon is stored in the layer file in advance, and for example, the higher the water quality grade is, the higher the water pollution degree is, and the darker the color of the water quality icon is; conversely, the lower the water quality rating, the lower the water pollution level, and the lighter the color of the water quality icon may be set. The water quality icon corresponding to the water quality grade can be obtained from the layer file according to the monitored water quality grade of the target site by adopting the GIS technology, and the water quality information of the target site is represented by the water quality icon.
Therefore, the water quality information of the target site is correspondingly displayed on the map by adopting the GIS technology according to the corresponding relation between the pre-stored water quality grade and the water quality icon, so that the water quality condition of the target site can be reflected by the water quality icon, and visual experience which is intuitive and clear at a glance can be provided for a user.
And S220, determining a target pollution source according to the target site.
In one possible embodiment, the determination of the target contamination source optionally comprises: determining the position relation between a target site and each candidate pollution source according to the position data of the target site and the position data of each candidate pollution source by adopting a GIS technology; and determining the target pollution source according to the position relation between the target site and each candidate pollution source.
The candidate contamination source may be a contamination source located around the target site, for example, a contamination source within a preset distance range with the target site as a center. The preset distance can be 100m or 1km, and the preset distance can be set according to actual needs. The location data may be a spatial geographical location coordinate, such as a longitude coordinate or a latitude coordinate. The positional relationship may be, for example, the relative distance of the target site from the candidate contamination source, or the direction of the target site relative to the candidate contamination source. According to the scheme, a GIS technology can be adopted to determine candidate pollution sources, namely target pollution sources, which are positioned at the upstream of the target site and have a distance relation with the target site according to the position data of the target site and the position data of each candidate pollution source.
Therefore, by adopting a GIS technology, the position relation between the target site and each candidate pollution source is determined according to the position data of the target site and the position data of each candidate pollution source; and determining the target pollution source according to the position relationship between the target site and each candidate pollution source, so that the search range of the pollution source can be reduced, and the search direction can be determined for further determining the final pollution source.
In another possible embodiment, optionally, the determination of the candidate contamination source comprises: and determining candidate pollution sources according to the position data of the target station and the preset distance.
In particular, the location data may be a spatial geographical location coordinate, such as a longitude coordinate or a latitude coordinate. The preset distance may be 500m, the preset distance may be 1000m, and the preset distance may be set as needed. Because the pollution source causing pollution to the water quality of the target site is associated with the target site in the geographical position, the pollution source determined by taking the target site as the center and taking the preset distance as the analysis radius can be used as a candidate pollution source. In the process of determining the candidate pollution source, the pollutant discharge time of the pollution source can be considered, for example, the target station is taken as the center, the preset distance is taken as the analysis radius, and the pollution source with the overproof element discharge record within half an hour or within one hour is taken as the candidate pollution source.
Therefore, the candidate pollution sources are determined according to the position data of the target station and the preset distance, the search range of the pollution sources can be narrowed, and the search direction is determined for further determining the target pollution sources.
And S230, determining a final pollution source according to the water quality exceeding information and pre-stored pollutant emission information of each target pollution source.
In this embodiment, optionally, the pollutant discharge information includes: at least one of an over-standard element emission value, an over-standard emission number, a critical over-standard emission number, and a complained number; correspondingly, determining a final pollution source according to the water quality exceeding information and the pre-stored pollutant emission information of each target pollution source, and the method comprises the following steps: if the following judgment conditions are met, determining the target pollution source as a final pollution source; the judgment conditions are as follows: the exceeding percentage and the exceeding element emission value of the target pollution source meet preset constraint conditions; and/or the number of times of overproof emission of the target pollution source is greater than a first preset threshold; and/or the critical exceeding emission times of the target pollution source is larger than a second preset threshold value; and/or the complained times of the target pollution source is larger than a third preset threshold value.
Specifically, the emission value of the superstandard element may be an actual emission value of the superstandard element at a specific time. The superscalar element emission value may also be a superscalar percentage of the superscalar element at a particular time. The number of emissions exceeding the standard emissions of the exceeding element may be the number of emissions in which the actual emission of the exceeding element exceeds the standard emission of the exceeding element for a period of time. The critical excess emissions number may be the number of emissions that the actual emissions of the excess element approach and exceed the standard emissions of the excess element over a period of time. The number of complains may be a total number of complains of the target pollution source over a period of time. The preset constraint condition may be that the overproof percentage of the overproof element of the target site is consistent with the emission value of the overproof element within a preset time. The preset constraint condition can also be that the difference between the standard exceeding percentage of standard exceeding elements of the target station and the emission value of the standard exceeding elements is less than a certain value in a preset time. The preset constraint condition can also be that the change trend of the standard exceeding percentage of the standard exceeding element of the target station is consistent with the change trend of the emission value of the standard exceeding element in the preset time. The first preset threshold may be 5, the first preset threshold may be 10, and the first preset threshold may be set according to actual needs. The second preset threshold may be 10, the second preset threshold may be 15, and the second preset threshold may be set according to actual needs. The third preset threshold may be 5, the third preset threshold may be 10, and the third preset threshold may be set according to actual needs.
Therefore, the exceeding percentage of the water quality exceeding information and the exceeding element emission value of the target pollution source meet the preset constraint condition; and/or the number of times of the overproof emission of the target pollution source is greater than a first preset threshold; and/or the critical exceeding emission times of the target pollution source is larger than a second preset threshold; and/or determining that the target pollution source is the final pollution source if the complaint times of the target pollution source are greater than a third preset threshold. The final pollution source of water pollution caused by the target site can be scientifically, efficiently and accurately determined.
In another possible embodiment, optionally, determining a final pollution source according to the water quality exceeding information and pre-stored pollutant emission information of each target pollution source includes: determining the position relation between a target site and each target pollution source according to the position data of the target site and the position data of the target pollution source by adopting a GIS technology; determining the acquisition time of pollutant emission information according to the position relationship between the target site and each target pollution source; and determining a final pollution source according to the water quality standard exceeding information, the pre-stored pollutant emission information of each target pollution source and each acquisition time.
In particular, the location data may be a spatial geographical location coordinate, such as a longitude coordinate or a latitude coordinate. The positional relationship may be, for example, the relative distance of the target site from the target contamination source, or the direction of the target site relative to the target contamination source. The acquisition time may be a period of time, such as half an hour, or one hour. The acquisition time may also be a specific moment. The scheme can adopt a GIS technology, the position relation between the target station and each target pollution source is determined according to the position data of the target station and the position data of the target pollution source, and the acquisition time of pollutant emission information is determined according to the position relation between the target station and each target pollution source. For example, if the target pollution source 1 is upstream of the target station and is 1000m away from the target station, the time period from 5 minutes before the current time to 35 minutes before the current time may be determined as the acquisition time of the pollutant discharge information of the target pollution source 1 according to the flow rate of wastewater of the target pollution source 1. For another example, if the target pollution source 2 is upstream of the target site and is 2000m away from the target site, the time period from 10 minutes before the current time to 40 minutes before the current time may be determined as the acquisition time of the pollutant discharge information of the target pollution source 2 according to the wastewater flow rate of the target pollution source 2. The scheme can determine the final pollution source according to the water quality standard exceeding information, the pre-stored pollutant emission information of each target pollution source and the acquisition time of the pollutant emission information of each target pollution source.
Therefore, by adopting a GIS technology, the position relation between the target site and each target pollution source is determined according to the position data of the target site and the position data of the target pollution source; determining the acquisition time of pollutant emission information according to the position relationship between the target station and each target pollution source; the final pollution source is determined according to the water quality standard exceeding information, the pre-stored pollutant emission information of each target pollution source and each acquisition time, the pollutant emission information in different acquisition times can be selected for the target pollution sources located at different positions of the target site, the final pollution source is determined according to the water quality standard exceeding information of the target site, and the determined final pollution source can be more accurate.
And S240, verifying the determination result of the final pollution source based on the overproof element online monitoring data of the final pollution source.
Specifically, after the final pollution source is determined, whether the determination result of the final pollution source is correct can be verified according to the online monitoring data of the overproof element of the final pollution source. For example, if the final pollution source is determined based on the percentage of the exceeding standard and the emission value of the exceeding standard elements of the target pollution source, the number of times the final pollution source emits the exceeding standard may be used to verify the determination result. Alternatively, for example, if the final pollution source is determined based on the number of complaints of the target pollution source, the determination result may be verified using the number of critical out-of-limit emissions of the final pollution source. Further improvements in the accuracy of determining the ultimate source of contamination may thereby be achieved.
According to the technical scheme provided by the embodiment of the invention, if the water quality exceeding information is received, the target site for acquiring the water quality exceeding information is determined; determining a target pollution source according to a target site; determining a final pollution source according to the water quality exceeding information and pre-stored pollutant emission information of each target pollution source; and verifying the determination result of the final pollution source based on the overproof element online monitoring data of the final pollution source. By executing the scheme, the pollution source causing water pollution can be scientifically, quickly and efficiently positioned, and the environmental improvement efficiency can be improved.
In the related technology, data of each water quality station and pollution source are displayed in a system in a form of a table, after the water quality stations in the jurisdiction send out an overproof alarm, environmental protection personnel need to find the pollution sources in the jurisdiction in the system, and then compare the pollution sources to check whether the pollution sources exceed the standard or not. The monitoring data of any pollution source is inquired, and the monitoring data needs to be clicked in from a list of pollutant emission information corresponding to the pollution source layer by layer, so that the efficiency is low, the efficiency is not visual enough, the accuracy of the positioning problem is not high, and the situation of no operation is often caused.
Fig. 3 is a flowchart of a tracing method of water pollution according to an embodiment of the present invention, and in order to more clearly describe the technical solution of the present invention, as shown in fig. 3, the technical solution according to the embodiment of the present invention may include the following steps:
