Description

Technical Field

[0001] This application relates to the field of rapid screening and early warning technology for new pollutants in the water environment, and in particular to a method and related apparatus for rapid initial screening of new pollutants. Background Technology

[0002] In recent years, with the widespread use of emerging pollutants (ECs) such as persistent organic pollutants (POPs), endocrine disruptors (EDCs), antibiotic resistance genes, and microplastics in industrial production, agricultural activities, and daily life, their residues in the aquatic environment have become increasingly serious. These emerging pollutants are typically characterized by low concentrations, high toxicity, environmental persistence, wide range of sources, and strong bioaccumulation, enabling them to persist in water bodies for extended periods and pose potential threats to ecosystems and human health. They have become a major focus of water environment governance. To address this issue, the General Office of the State Council issued the "Action Plan for the Governance of Emerging Pollutants," proposing the establishment of an environmental survey and monitoring system and the improvement of monitoring technology systems to provide a policy basis for the systematic monitoring and risk prevention and control of emerging pollutants.

[0003] Currently, the detection of new pollutants mainly relies on two types of technologies: targeted detection and non-targeted screening. However, these technologies have significant limitations in early warning monitoring and emergency response in complex aquatic environments. Targeted detection relies on high-precision analytical instruments such as gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS), based on known standards. Its detection range is limited, making it difficult to identify the large number of new pollutants and their metabolites with complex structures and diverse transformation pathways. Furthermore, sample pretreatment is cumbersome, detection cycles are long, equipment costs are high, and operational requirements are stringent, making it difficult to meet the needs of rapid, large-scale, real-time monitoring. While non-targeted screening utilizes high-resolution mass spectrometry (HRMS) and theoretically possesses broad coverage, the sheer volume of raw data, complex analysis, and low confidence in the identification of unknown substances limit its detection efficiency and repeatability. Moreover, the rapid increase in the types of new pollutants means that existing non-targeted monitoring databases cannot fully cover them, resulting in limited identification capabilities and the risk of missed detections. Therefore, the screening efficiency, coverage, and practical application flexibility of new pollutants face severe challenges, necessitating the development of efficient, rapid, and broad-coverage new screening technologies. Summary of the Invention

[0004] The purpose of this application is to provide a method and related apparatus for rapid initial screening of new pollutants, which can be used to quickly screen for new pollutants with abnormal water quality, and provide a basis for the identification of water pollution sources and the precise supervision of new pollutants.

[0005] To achieve the above objectives, this application provides the following solution.

[0006] In a first aspect, this application provides a method for rapid initial screening of new pollutants, the method comprising the following steps.

[0007] A preliminary screening database for new pollutants is constructed; the preliminary screening database for new pollutants includes: an industry database of water quality fluorescence fingerprints of pollution sources and an industry database of new pollutants.

[0008] Obtain water quality testing or monitoring results from key locations in the target water body, including fluorescent fingerprinting and routine indicator testing.

[0009] When the water quality test or monitoring results show that conventional water quality indicators exceed the standard, the intensity of water quality fluorescent fingerprint exceeds the standard, or the component characteristics exceed the preset characteristics, the results are compared with the pollution source water quality fluorescent fingerprint industry database to obtain the comparison results.

[0010] When the comparison result is above the preset value, it is determined to be a suspected emission source, and the industry type of the pollution source is determined by combining the pollution source water quality fluorescence fingerprint industry database.

[0011] When the comparison result is less than the preset value, it is determined to be an unknown pollution source. Based on the national industry water quality fluorescent fingerprint database, the industry type of the pollution source is inferred. At the same time, the water quality fluorescent fingerprint pollution path identification method is used to identify suspected emission sources. The national industry water quality fluorescent fingerprint database is a database constructed using the most common and typical water quality fingerprint signal features of different industries across the country.

[0012] Based on the suspected emission sources and the corresponding industry types of pollution sources, the system automatically calls the database of new pollutant industries to determine the types of new pollutants in the water body.

[0013] Optionally, a preliminary screening database for new pollutants may be constructed, which includes the following steps.

[0014] Obtain water samples, basic information on regional pollution sources, and basic information on regional industries within the regulated area. The basic information on regional pollution sources includes: company name, industry category, geographical location, legal representative, contact person, company production status, production cycle, production process, products produced, water-related processes, location of discharge outlets, and company water pollution penalty records. The basic information on regional industries includes: industry classification, typical production processes, and raw and auxiliary material information.

[0015] The sampled water samples were analyzed using water quality fluorescence fingerprinting and conventional water quality index analysis to obtain typical characteristics of the water quality fluorescence fingerprint of the pollution source enterprise and conventional water quality index data of the pollution source. The typical characteristics of the water quality fluorescence fingerprint of the pollution source enterprise include: water quality fluorescence fingerprint data of the pollution source and ultraviolet-visible absorption spectrum data of the pollution source. The conventional water quality index data of the pollution source includes: pH, conductivity, chemical oxygen demand, ammonia nitrogen, total nitrogen, and total phosphorus.

[0016] Based on the typical characteristics of the fluorescent fingerprints of the water quality of the pollution source enterprises and the conventional water quality index data of the pollution sources, a fluorescent fingerprint database of the water quality of pollution sources is constructed.

[0017] Based on the aforementioned pollution source water quality fluorescence fingerprint database, fingerprint features of typical industries are extracted and classified to construct an industry database of pollution source water quality fluorescence fingerprints.

[0019] Based on the regional industry basic information, the control information, and the emission characteristics of the new pollutants, a new pollutant industry database is constructed.

[0020] Optionally, the water quality fluorescent fingerprint pollution path identification method involves collecting water quality fingerprints from abnormal locations and upstream water samples for testing and comparison. The investigation scope is continuously narrowed down using a dichotomy method. Based on the water flow direction, pollutant diffusion patterns, and surrounding emission characteristics, the location of potential upstream emission sources is inferred, the investigation scope is narrowed down, and the pollution emission source is finally identified.

[0021] Optionally, the method for rapid preliminary screening of new pollutants further includes generating a preliminary screening list based on the types of new pollutants in the water body.

[0025] The comparison module is used to compare the water quality with the pollution source water quality fluorescent fingerprint industry database when the water quality detection or monitoring results show that the conventional water quality indicators exceed the standard, the water quality fluorescent fingerprint intensity exceeds the standard, or the component characteristics exceed the preset characteristics, and obtain the comparison results.

[0026] The first determination module is used to determine a suspected emission source when the comparison result is above a preset value, and to determine the industry type of the pollution source in conjunction with the pollution source water quality fluorescent fingerprint industry database.

[0027] The second determination module is used to determine an unknown pollution source when the comparison result is less than a preset value, and to infer the industry type of the pollution source based on the national industry water quality fluorescent fingerprint database. At the same time, it uses the water quality fluorescent fingerprint pollution path identification method to identify suspected emission sources. The national industry water quality fluorescent fingerprint database is a database constructed using the most common and typical water quality fingerprint signal features of different industries across the country.

[0028] The new pollutant type determination module is used to automatically call the new pollutant industry database to determine the new pollutant type in the water body based on the suspected emission source and the corresponding pollution source industry type.

[0029] Optionally, the new pollutant initial screening database construction module includes the following units.

[0030] The information acquisition unit is used to acquire water samples, basic information on regional pollution sources, and basic information on regional industries within the regulatory area. The basic information on regional pollution sources includes: company name, industry category, geographical location, legal representative, contact person, company production status, production cycle, production process, products produced, water-related processes, discharge outlet location, and company water pollution penalty records. The basic information on regional industries includes: industry classification, typical production processes, and raw and auxiliary material information.

[0031] The analysis unit is used to perform water quality fluorescence fingerprint and conventional water quality index analysis on the sampled water sample to obtain the typical characteristics of the water quality fluorescence fingerprint of the pollution source enterprise and the conventional water quality index data of the pollution source; the typical characteristics of the water quality fluorescence fingerprint of the pollution source enterprise include: water quality fluorescence fingerprint data of the pollution source and ultraviolet-visible absorption spectrum data of the pollution source; the conventional water quality index data of the pollution source includes: pH, conductivity, chemical oxygen demand, ammonia nitrogen, total nitrogen, and total phosphorus.

[0032] The pollution source water quality fluorescence fingerprint database construction unit is used to construct a pollution source water quality fluorescence fingerprint database based on the typical characteristics of the pollution source enterprise's water quality fluorescence fingerprint and the pollution source's conventional water quality index data.

[0033] The pollution source water quality fluorescent fingerprint industry database construction unit is used to extract and classify typical industry fingerprint features based on the pollution source water quality fluorescent fingerprint database, and construct the pollution source water quality fluorescent fingerprint industry database.

[0034] The new pollutant emission characteristic determination unit is used to determine the emission characteristics of new pollutants based on the regional industry basic information and control information; the control information includes: national and local new pollutant lists and industry emission limits and related laws and policies; the new pollutant emission characteristics include: typical new pollutant types in the industry, characteristic concentrations of each new pollutant in different industries, and lists of priority controlled substances.

[0035] The new pollutant industry database construction unit is used to construct a new pollutant industry database based on the regional industry basic information, the control information, and the emission characteristics of the new pollutants.

[0036] Optionally, the water quality fluorescent fingerprint pollution path identification method involves collecting water quality fingerprints from abnormal locations and upstream water samples for testing and comparison. The investigation scope is continuously narrowed down using a dichotomy method. Based on the water flow direction, pollutant diffusion patterns, and surrounding emission characteristics, the location of potential upstream emission sources is inferred, the investigation scope is narrowed down, and the pollution emission source is finally identified.

[0037] Optionally, the system for rapid initial screening of new pollutants further includes: an initial screening list generation module, used to generate an initial screening list based on the types of new pollutants in the water body.

[0038] Thirdly, this application provides a computer device, including: a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the computer program to implement the rapid initial screening method for novel pollutants as described in any of the first aspects.

[0039] Fourthly, this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the rapid initial screening method for novel pollutants as described in the first aspect.

[0040] Based on the specific embodiments provided in this application, the following technical effects are disclosed.

[0041] This application provides a method and related apparatus for rapid initial screening of new pollutants. The method includes: constructing a new pollutant initial screening database; the new pollutant initial screening database includes a pollution source water quality fluorescence fingerprint industry database and a new pollutant industry database; this step can provide comprehensive and categorized basic data support for subsequent rapid initial screening. Water quality detection or monitoring results are obtained by conducting water quality fluorescence fingerprint and conventional indicator detection at key points in the target water body; this step ensures that the detection data used for initial screening is targeted and effective. When the water quality detection or monitoring results show that conventional water quality indicators exceed standards, water quality fluorescence fingerprint intensity exceeds standards, or component characteristics exceed preset characteristics, the results are compared with the pollution source water quality fluorescence fingerprint industry database to obtain comparison results; this step compares the water body detection results with the pollution source water quality fluorescence fingerprint industry database when the water body detection results are abnormal, achieving preliminary source tracing of the abnormal water body. When the comparison result is above a preset value, it is determined as a suspected emission source, and the pollution source industry type is determined in conjunction with the pollution source water quality fluorescence fingerprint industry database; this step determines the suspected emission source and the pollution source industry type by using the comparison result threshold, which can improve the accuracy and efficiency of emission source identification. When the comparison result is less than a preset value, it is determined to be an unknown pollution source. Based on the national industry water quality fluorescent fingerprint database, the industry type of the pollution source is inferred, and the water quality fluorescent fingerprint pollution path identification method is used to identify suspected discharge sources. The national industry water quality fluorescent fingerprint database is a database constructed using the most common and typical water quality fingerprint signal features of different industries across the country. This step combines the national industry database to infer the industry type of unknown pollution sources and identify suspected discharge sources, thus broadening the coverage and applicability of pollution source identification. Based on the suspected discharge source and the corresponding pollution source industry type, the matching new pollutant industry database is automatically invoked to determine the type of new pollutant in the water body. This step, based on the suspected discharge source and industry type, invokes the new pollutant industry database to determine the type of new pollutant, enabling accurate correlation from pollution source to pollutant type. This application, through database construction, hierarchical comparison, and source tracing identification, forms a complete and rapid initial screening process from anomaly detection to pollutant type determination, improving the efficiency, accuracy, and coverage of new pollutant initial screening, and providing an efficient and feasible technical path for the early detection and control of new pollutants.

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] Fluorescent fingerprinting technology for water pollution source tracing has the ability to identify pollution sources, quickly pinpointing pollution sources and narrowing the scope of investigation. It can effectively monitor illegal discharges, leaks, and excessive discharges by water-related enterprises. This technology has now been instrumented and standardized. It is widely used in water pollution monitoring and initial screening of pollution sources, offering advantages such as speed, sensitivity, and visualization. However, with the continuous emergence of new pollutants in the aquatic environment, their diverse types, complex structures, and varied transformation pathways make it difficult for traditional detection methods to achieve efficient identification and rapid screening.

[0051] Therefore, deeply integrating water quality fluorescent fingerprinting technology with an industry database of emerging pollutants can significantly improve the rapid initial screening capability for emerging pollutants while maintaining source tracing efficiency. This method offers advantages such as low personnel requirements, rapid screening speed, and no need for reagents. By constructing an industry database of water quality fluorescent fingerprints for pollution sources and an industry database of emerging pollutants, it enables the comparison, identification, and locking of suspected emission sources. Combined with the national industry database of water quality fluorescent fingerprints, it accurately determines the industry type of the pollution source. Simultaneously, relying on the industry database of emerging pollutants, it can quickly identify the main types of emerging pollutants in water bodies, thereby achieving efficient and targeted rapid screening of emerging pollutants. This technology significantly improves screening efficiency and accuracy, providing strong technical support for rapid screening of emerging pollutants in the aquatic environment, early warning of emerging pollutants in the aquatic environment, risk assessment, scientific management, and prevention and control decision-making.

[0052] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] The rapid initial screening method for novel pollutants provided in this application embodiment can be applied to, for example... Figure 1In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be set up independently, integrated into server 104, or placed in the cloud or on other servers. Terminal 102 can send a newly constructed preliminary screening database of pollutants to server 104. This database includes an industry database of water quality fluorescence fingerprints from pollution sources and an industry database of new pollutants. After receiving the preliminary screening database, server 104 obtains the water quality detection or monitoring results from key locations in the target water body, including water quality fluorescence fingerprints and conventional indicator detection. When the water quality detection or monitoring results show that conventional water quality indicators exceed standards, water quality fluorescence fingerprint intensity exceeds standards, or component characteristics exceed preset characteristics, the results are compared with the industry database of water quality fluorescence fingerprints from pollution sources to obtain a comparison result. When the comparison result is above a preset value... If a source is identified as a suspected discharge source, its industry type is determined by combining the pollution source water quality fluorescence fingerprint industry database. If the comparison result is less than a preset value, it is identified as an unknown pollution source, and its industry type is inferred based on the national industry water quality fluorescence fingerprint database. Simultaneously, a water quality fluorescence fingerprint pollution path identification method is used to identify the suspected discharge source. The national industry water quality fluorescence fingerprint database is a database constructed using the most common and typical water quality fingerprint signal features of different industries across the country. Based on the suspected discharge source and its corresponding pollution source industry type, the system automatically calls and matches the new pollutant industry database to determine the type of new pollutant in the water body. The server 104 can then feed back the obtained types of new pollutants in the water body to the terminal 102. In addition, in some embodiments, the method for rapid initial screening of new pollutants can also be implemented by the server 104 or the terminal 102 alone. For example, the terminal 102 can directly obtain the water quality fluorescence fingerprint and conventional index detection results at key points of the target water body to perform rapid initial screening of new pollutants. Alternatively, the server 104 can obtain the water quality fluorescence fingerprint and conventional index detection results at key points of the target water body from the data storage system and perform rapid initial screening of new pollutants based on the water quality fluorescence fingerprint and conventional index detection results at key points of the target water body.

[0054] The terminal 102 can be, but is not limited to, various desktop computers, laptops, smartphones, and tablets. The server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers, or it can be a cloud server.

[0055] In one exemplary embodiment, such as Figure 2As shown, a method for rapid initial screening of new pollutants is provided. This method is executed by computer equipment, specifically by a terminal or server alone, or by both a terminal and a server. In this embodiment, the method is applied to... Figure 1 Taking server 104 as an example, the following steps are included.

[0056] S1: Construct a preliminary screening database for new pollutants; the preliminary screening database for new pollutants includes: an industry database of fluorescent fingerprints of water quality from pollution sources and an industry database of new pollutants.

[0057] S2: Obtain water quality testing or monitoring results at key points in the target water body, including fluorescent fingerprinting and routine indicator testing.

[0058] S3: When the water quality test or monitoring results show that conventional water quality indicators exceed the standard, the intensity of water quality fluorescent fingerprint exceeds the standard, or the component characteristics exceed the preset characteristics, the results are compared with the pollution source water quality fluorescent fingerprint industry database to obtain the comparison results.

[0059] S4: When the comparison result is above the preset value, it is determined to be a suspected emission source, and the industry type of the pollution source is determined by combining the pollution source water quality fluorescent fingerprint industry database.

[0060] S5: When the comparison result is less than the preset value, it is determined to be an unknown pollution source. Based on the national industry water quality fluorescent fingerprint database, the industry type of the pollution source is inferred. At the same time, the water quality fluorescent fingerprint pollution path identification method is used to identify the suspected emission source. The national industry water quality fluorescent fingerprint database is a database constructed using the most common and typical water quality fingerprint signal features of different industries across the country.

[0061] S6: Based on the suspected emission source and the corresponding pollution source industry type, automatically call the matching new pollutant industry database to determine the type of new pollutant in the water body.

[0062] Implementing steps S1 to S6 above can be used to rapidly screen for new pollutants with abnormal water quality, providing a basis for water pollution source identification and precise monitoring of new pollutants. This application covers the entire process from the construction of a preliminary screening database for new pollutants, water monitoring and anomaly identification, identification of suspected emission sources and industry determination, and preliminary screening of new pollutant types, and is applicable to the rapid identification and screening of new pollutants in complex aquatic environments.

[0063] As an optional implementation, in step S1, a new pollutant screening database is constructed, which specifically includes the following steps.

[0064] S11: Obtain water samples, basic information on regional pollution sources, and basic information on regional industries within the regulated area; the basic information on regional pollution sources includes: company name, industry category, geographical location, legal representative, contact person, company production status, production cycle, production process, products produced, water-related processes, location of discharge outlets, and company water pollution penalty records; the basic information on regional industries includes: industry classification, typical production processes, and raw and auxiliary material information.

[0065] S12: Perform water quality fluorescence fingerprint and conventional water quality index analysis on the sampled water samples to obtain typical characteristics of the water quality fluorescence fingerprint of the pollution source enterprise and conventional water quality index data of the pollution source; the typical characteristics of the water quality fluorescence fingerprint of the pollution source enterprise include: water quality fluorescence fingerprint data of the pollution source and ultraviolet-visible absorption spectrum data of the pollution source; the conventional water quality index data of the pollution source includes: pH, conductivity, chemical oxygen demand, ammonia nitrogen, total nitrogen, and total phosphorus.

[0066] S13: Based on the typical characteristics of the water quality fluorescence fingerprint of the pollution source enterprises and the conventional water quality index data of the pollution sources, construct a water quality fluorescence fingerprint database for pollution sources.

[0067] S14: Based on the aforementioned pollution source water quality fluorescence fingerprint database, extract and classify typical industry fingerprint features to construct a pollution source water quality fluorescence fingerprint industry database.

[0068] S15: Based on the regional industry basic information and control information, determine the emission characteristics of new pollutants; the control information includes: national and local lists of new pollutants and industry emission limits and related laws and policies; the emission characteristics of new pollutants include: typical new pollutant types in the industry, characteristic concentrations of each new pollutant in different industries, and lists of priority controlled substances.

[0069] S16: Based on the regional industry basic information, the control information, and the emission characteristics of the new pollutants, construct a new pollutant industry database.

[0070] As an optional implementation method, the water quality fluorescent fingerprint pollution path identification method tests and compares water quality fingerprints by collecting abnormal points and upstream water samples. The investigation scope is continuously narrowed down by using a dichotomy method. Based on the water flow direction, pollutant diffusion patterns and surrounding emission characteristics, the location of potential upstream emission sources is inferred, the investigation scope is narrowed down, and finally the pollution emission source is identified.

[0071] As an optional implementation method, the rapid preliminary screening method for new pollutants further includes: generating a preliminary screening list based on the types of new pollutants in the water body.

[0072] As an optional implementation method, in step S6, the new pollutant type is accurately determined by automatically calling the matching new pollutant industry database. This can significantly improve the targeting and efficiency of new pollutant identification by relying on the correspondence between the industry type of the pollution source and the new pollutant, avoiding the waste of resources caused by blind screening. At the same time, the industry-specific characteristics of the database ensure the reliability of the determination results, providing core technical support for the rapid initial screening of new pollutants, helping to quickly locate potential new pollutants in water bodies, and providing accurate basis for subsequent pollution prevention and control and treatment.

[0073] In practical applications, such as Figure 3 As shown, it includes the following steps.

[0074] Step 1: Construction of a preliminary screening database for new pollutants.

[0075] By conducting systematic research and analysis on key pollution sources within the regulatory area, high-risk enterprises with large emissions and highly toxic wastewater were screened, and systematic sampling was carried out in accordance with relevant technical specifications.

[0076] After the collected water samples were analyzed by water quality fluorescence fingerprint and conventional water quality indicators, a pollution source water quality fluorescence fingerprint database was constructed. Typical industry fingerprint features were extracted and classified to form a pollution source water quality fluorescence fingerprint industry database.

[0077] At the same time, based on surveys of polluting entities, national and local lists of new pollutants under control, and relevant scientific research literature, we compiled the emission characteristics of typical new pollutants in various industries, including pollutant types, emission concentrations, and lists of priority controlled substances.

[0078] This process leverages data retrieval to improve efficiency while also considering potential biases, allowing for necessary field testing of new pollutants based on actual conditions. The resulting industry database of new pollutants, complementing the industry database of fluorescent fingerprints for polluted water sources, provides scientific, systematic, and reliable data support for rapid screening of new pollutants.

[0079] The new pollutant screening database mainly includes the following:

[0080] 1) Pollution Source Water Quality Fluorescent Fingerprint Industry Database. The pollution source water quality fluorescent fingerprint industry database includes the following:

[0081] ① Basic information on regional pollution sources: company name, industry category, geographical location, legal representative, contact person, company production status, production cycle, production process, products produced, water-related processes, location of discharge outlets, and company water pollution penalty records, etc.

[0082] ② Fluorescent fingerprint data of water quality from pollution sources: Fluorescent fingerprint data of water quality from pollution sources and ultraviolet-visible absorption spectrum data of pollution sources (extracting typical features of the fluorescent fingerprint of water quality from pollution source enterprises).

[0083] ③ Routine water quality indicators of pollution sources: pH, conductivity, chemical oxygen demand, ammonia nitrogen, total nitrogen, and total phosphorus. (Understand the basic characteristics and characteristic pollutants of wastewater from pollution sources).

[0084] 2) New Pollutant Industry Database. The new pollutant industry database includes the following:

[0085] ① Regional industry basic information: industry classification (e.g., pharmaceuticals, chemicals, printing and dyeing, electronics, pesticides, etc.) as well as typical production processes and raw and auxiliary material information.

[0086] ② Characteristics of new pollutant emissions: Typical new pollutant types in the industry (e.g., persistent organic pollutants, endocrine disruptors, antibiotics and microplastics), characteristic concentrations of each new pollutant in different industries, and a list of key controlled substances (high-risk substances).

[0087] ③ Control information: National and local lists of new pollutants, industry emission limits and related laws and regulations.

[0088] Step 2: Water monitoring and anomaly identification.

[0089] Water quality fluorescence fingerprinting and routine indicators (pH, conductivity, dissolved oxygen, ammonia nitrogen, total phosphorus, COD, etc.) are tested at key points in important water bodies. Integrated online water pollution early warning and source tracing stations, mobile water pollution early warning and source tracing laboratories, or manual sampling and testing can be flexibly selected according to actual needs. Through multi-dimensional monitoring methods, rapid identification of abnormal water conditions can be achieved, providing accurate and efficient data support for subsequent pollution source identification and initial screening of new pollutants.

[0090] Step 3: Identification of suspected emission sources and industry determination.

[0091] When water quality test results show that conventional water quality indicators exceed the standard, the intensity of water quality fluorescent fingerprint exceeds the standard, or the composition characteristics change significantly, the tested water quality fluorescent fingerprint will be compared with the industry database of pollution source water quality fluorescent fingerprints.

[0092] 1) When the similarity of the fluorescent fingerprint of the water quality of the pollution source is ≥60%, it is identified as a suspected emission source. The suspected emission source can be quickly located, and the industry type of the pollution source can be accurately determined by combining the industry database of fluorescent fingerprint of the water quality of the pollution source.

[0093] 2) When the similarity of the fluorescent fingerprint of the pollution source water quality is less than 60%, the system will determine it as an unknown pollution source and will not point to any known emission source, indicating that there may be a potential new pollution source that is not included in the existing pollution source water quality fluorescent fingerprint industry database.

[0094] When a local industry database of water quality fluorescence fingerprints for pollution sources has not yet been established, the national industry database of water quality fluorescence fingerprints can be relied upon. The national industry database of water quality fluorescence fingerprints utilizes the most common and typical water quality fingerprint signal characteristics of different industries across the country. It has universality (characteristics that are commonly found in a certain industry) and can provide targeted information for industry source tracing. By comparing and analyzing fingerprint similarity, the approximate industry type to which the pollution source belongs can be inferred.

[0095] Simultaneously, a water quality fluorescent fingerprint pollution path identification method is employed. This method involves collecting water samples from anomaly points and upstream areas to test and compare water quality fingerprints. Through a dichotomy approach, the investigation scope is continuously narrowed down. Based on water flow direction, pollutant diffusion patterns, and surrounding discharge characteristics, the location of potential upstream discharge sources is inferred, further narrowing the investigation scope and ultimately identifying the pollution source. The water quality fluorescent fingerprint pollution path identification method is as follows: Figure 4 As shown.

[0096] This strategy can still achieve efficient screening of suspected pollution sources and industry types even when the database is incomplete, providing reliable reference information for the initial screening of new pollutants and early warning of new pollutants in the water environment.

[0097] Step 4: Initial screening of new pollutant types.

[0098] Based on identified suspected emission sources and their industry types, the system automatically accesses a database of new pollutants by industry. This database includes: a list of typical new pollutants for each industry; the emission probability and typical concentration range for each pollutant; high-frequency emitters, industry-specific pollutants, and controlled species. The system compares and analyzes typical emission characteristics based on the industry to which the suspected emission source belongs, accesses the corresponding industry database of new pollutants, determines the types of new pollutants that may exist in the water body, and generates a preliminary screening list covering high-frequency new pollutant emission types, typical concentration ranges for new pollutants, and a list of controlled substances.

[0099] This initial screening list can be directly used for subsequent quantitative analysis, risk assessment, and management decision-making, enabling rapid, targeted, and accurate screening of new pollutants. Through deep integration with the results of suspected emission source identification, this method significantly improves the efficiency and accuracy of new pollutant screening, providing solid data support and technical assurance for risk assessment, early warning, and prevention and control of new pollutants in the aquatic environment.

[0100] In summary, the "method for rapid initial screening of new pollutants" proposed in this application has significant advantages in terms of detection and identification efficiency, identification accuracy, applicability, and regulatory targeting. This method is simple to operate, requires minimal personnel, has a fast screening speed, and requires no reagents. These advantages are achieved through the construction of a new pollutant initial screening database. This method deeply integrates water quality fluorescent fingerprint technology with a new pollutant industry database to construct a new pollutant initial screening database. Water quality fluorescent fingerprint pollution source tracing technology has the ability to identify pollution source emissions and can quickly pinpoint the pollution source and industry type. By coupling water quality fluorescent fingerprint technology, the ability to rapidly screen new pollutants can be significantly improved while maintaining source tracing efficiency. This method has advantages such as low personnel requirements, fast screening speed, and no reagents required. Furthermore, the new pollutant initial screening database is constructed on-site according to regional characteristics and can be dynamically updated, which can significantly reduce the risk of missed detection of unknown new pollutants and significantly improve the identification accuracy and reliability in the initial screening stage of new pollutants. By constructing an industry database of fluorescent fingerprints for water quality at pollution sources and an industry feature database for new pollutants, the technology enables the comparison, identification, and locking of suspected emission sources. Combined with a national industry database of fluorescent fingerprints for water quality, it accurately determines the industry type to which the pollution source belongs.
