Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
In today's society, the problem of water pollution is becoming increasingly serious. It is a very difficult task to enhance the monitoring and treatment of water pollution. The tracing of the pollutants is an important link for treating water pollution, and generally refers to tracking and positioning the pollution sources of the pollutants in the river after a water pollution accident occurs in the river. Only if the tracing of the pollutants is well realized, the pollution source can be effectively cut off, and the pollution condition is prevented from further worsening.
In the prior art, a method for tracing the source of pollutants is as follows: and a water quality monitoring device is arranged in a known water outlet in the river channel to monitor the water quality in real time, and when the water quality is abnormal, a main drainage body is determined according to the communication relation of the water outlet. However, the method is ideal, and the stealing and draining port of the overproof waste water of an enterprise is often very hidden, so that the monitoring is basically in a failure state.
In the prior art, another method for tracing the source of pollutants is also provided, and workers periodically monitor the water quality of a target point in a monitoring range so as to monitor the water quality. Wherein, the target point location is a point location provided with a water quality monitoring station. When discovering that quality of water is unusual, the environmental protection worker confirms the sewage discharge enterprise that probably causes quality of water to be unusual according to the experience to carry out the environmental protection and supervise to sewage discharge enterprise.
However, in the manual inspection method, on one hand, workers cannot find out the water quality abnormality in time, and on the other hand, sewage discharge enterprises determined by the workers according to experience are often inaccurate, so that the pollution source cannot be determined quickly and accurately.
At present, methods for tracing the source of pollutants further include an off-line pollutant chemical composition analysis method, a fluorescence spectrum analysis method, a microorganism tracing and tracing method, a water quality model numerical inversion method and the like. However, in practical applications, it is difficult for these methods to function well in practical operations in the comprehensive management of water environments in a wide large basin at the administrative level of county and city. Because the off-line pollutant chemical composition analysis method, the fluorescence spectrum analysis method, the microorganism tracing and tracing method and the like generally have slow response speed, the method is often used for after-the-fact tracing, and the pollution source cannot be quickly determined. The water quality model numerical inversion method can only be used for small sections of specific riverways, has more assumptions and preconditions, and cannot be well popularized in practical application.
The embodiment of the application provides a pollutant tracing method, which can rapidly determine a target pollution industry by acquiring water quality characteristics and characteristic pollutants of water at a pollution monitoring point position where a water pollution event occurs, and then taking a main body belonging to the target pollution industry in a pollution tracing range corresponding to the pollution monitoring point position as a pollution source object. Therefore, the pollution source object can be quickly and accurately determined by combining the test treatment and the geographical range limitation mode, and the efficiency of tracing the source of the pollutants is improved.

The background server comprises a processor, a memory, a network interface and a database which are connected through a system bus. Wherein the processor of the background server is configured to provide computing and control capabilities. The memory of the background server comprises a nonvolatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a computer program, and a database. The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium. The database of the background server is used for storing a water system diagram, a water quality characteristic database and a characteristic pollutant database of a supervision area. The network interface of the background server is used for being connected and communicated with an external terminal through a network. The computer program is executed by a processor to implement a method of tracing a source of a contaminant.

Generally, the wastewater discharged by each pollution industry has the characteristics of the industry, and the water quality characteristics of the wastewater discharged by the same pollution industry and the characteristic pollutants of the pollution industry have closer correlation. For example, in the wastewater discharged from a fertilizer plant, the content of ammonia nitrogen is generally high, and the characteristic pollutant is generally nutrient elements such as ammonia nitrogen. The content of organic solvents is generally high in the waste water discharged by the printing industry, and characteristic pollutants are generally high-boiling point petroleum, alcohols, ethers, ketones and the like. The content of heavy metal in the wastewater discharged by the electroplating industry is higher, and the characteristic pollutants are generally cyanate ions, heavy metal ions and the like.
In this embodiment, a target pollution industry is determined from a plurality of pollution industries according to the water quality characteristics and characteristic pollutants of water at the pollution monitoring point. In this embodiment, the target pollution industry may be a plurality of pollution industries or may be one pollution industry.
And 203, determining a pollution source object from a pollution tracing range corresponding to the pollution monitoring point location by the server according to the target pollution industry, wherein the pollution source object is a main body of a water pollution event causing the pollution monitoring point location.
In this embodiment, the pollution tracing range is a geographical range, and the pollution tracing range corresponding to the pollution monitoring point location can be understood as an area within a certain range near the location of the pollution monitoring point location. The contamination source object is the subject of a water contamination event that may cause a contamination monitoring site.

According to the target pollution industry, the enterprises which belong to the same industry as the target pollution industry are found out from all enterprises in the pollution tracing range, the found enterprises are pollution source objects, and the pollution source objects are main bodies of water pollution events which possibly cause pollution monitoring points.
Optionally, when a plurality of target pollution industries exist, the pollution source object corresponding to each target pollution industry can be searched one by one from all enterprises within the pollution tracing range. Alternatively, the contamination source object may be plural.
It should be noted that, when an enterprise corresponding to the target pollution industry is not found within the pollution tracing range, in this embodiment, a pollution tracing range corresponding to an adjacent target point near the pollution monitoring point may be obtained, and a pollution source object that belongs to the same industry as the target pollution industry is found from all enterprises within the pollution tracing range corresponding to the adjacent target point.
According to the pollutant tracing method provided by the embodiment, the target pollution industry can be quickly determined by obtaining the water quality characteristics and characteristic pollutants of the water at the pollution monitoring point, then, the enterprises of which the industries are the same as the target pollution industry are found out from all the enterprises in the pollution tracing range corresponding to the pollution monitoring point, and the found enterprises are determined as the pollution source objects. The mode of combining together experimental data and geographical inquiry scope can determine the pollution source object fast, has improved the efficiency that the pollutant was traced to the source to, compare in prior art, saved a lot of manpower and materials.
In an alternative implementation, as shown in fig. 3, step 202 further includes the following:
The water quality characteristic database stores basic water quality characteristics of the polluted industries in the supervision area and wastewater corresponding to each polluted industry.
In this embodiment, the process of establishing the water quality characteristic database may include the following steps: the environmental protection department can acquire all pollution enterprises in the supervision area and pollution industries to which the pollution enterprises belong in advance.
Furthermore, the wastewater discharged by a plurality of pollution enterprises belonging to the same pollution industry can be sampled and analyzed to obtain the water quality characteristics of the wastewater discharged by the plurality of pollution enterprises belonging to the same pollution industry, and the water quality characteristics are referred to as basic water quality characteristics in the embodiment.
And establishing a water quality characteristic database according to the acquired basic water quality characteristics of the wastewater corresponding to all pollution industries and all pollution industries in the supervision area.
The server can compare the water quality characteristics of the pollution monitoring points with the basic water quality characteristics in the water quality characteristic database one by one, and when the water quality characteristics of the pollution monitoring points are completely the same as or partially the same as the basic water quality characteristics, the pollution industry corresponding to the basic water quality characteristics is determined as a first candidate pollution industry corresponding to the water quality characteristics of the pollution monitoring points.
And when a plurality of pollution industries are determined according to the water quality characteristics of the pollution monitoring points, forming a first candidate pollution industry set by the plurality of pollution industries.
In an alternative implementation, as shown in fig. 4, the process of determining the first candidate set of pollution industries from the water quality characteristics database according to the water quality characteristics may include the following:
In the embodiment of the application, the water quality characteristics may include statistical characteristics and spectral characteristics, and correspondingly, the basic water quality characteristics include basic statistical characteristics and basic spectral characteristics.
In the embodiment of the application, for each basic water quality characteristic, the statistical characteristic of the pollution point location and the basic statistical characteristic in the water quality characteristic database can be matched to obtain a first matching degree; the statistical characteristics can adopt algorithms such as positive definite matrix decomposition and the like to extract a water quality component spectrum, and the matching algorithm can adopt an Euclidean distance method and the like. Matching the spectral characteristics of the polluted point location with the basic spectral characteristics in the water quality characteristic database to obtain a second matching degree; the spectral feature matching can be automated similarity matching by adopting various methods such as direct correlation analysis of spectral data, correlation analysis of a moving window, comparison of spectral peak position information, comparison of image similarity in machine vision and the like. And then carrying out weighted operation on the first matching degree and the second matching degree to obtain the matching degree between the water quality characteristics and the basic water quality characteristics.

And when the matching degree between the water quality characteristics of the pollution monitoring point and certain basic water quality characteristics is greater than a matching threshold value, determining the pollution industry corresponding to the basic water quality characteristics as a first candidate pollution industry.
When the matching degree between the water quality characteristics of the pollution monitoring point and certain basic water quality characteristics is smaller than or equal to the matching threshold, the pollution industry corresponding to the basic water quality characteristics is not the first candidate pollution industry.
By the method, a plurality of first candidate polluted industries can be screened out, and the first candidate polluted industries can be combined to obtain a first candidate polluted industry set.
The characteristic pollutant database stores pollution industries in a supervision area and basic characteristic pollutants corresponding to the pollution industries.

When the characteristic contaminant of the water corresponding to the pollution monitoring point is one, the characteristic contaminant of the water corresponding to the pollution monitoring point may be referred to as a target characteristic contaminant in this embodiment. The server can combine all pollution industries corresponding to the basic characteristic pollutants containing the target characteristic pollutants to obtain a second candidate pollution industry set.
When the characteristic contaminants of the water corresponding to the pollution monitoring point location are multiple, in this embodiment, it may be considered that the water corresponding to the pollution monitoring point location contains multiple target characteristic contaminants.
