Description

Technical Field

[0001] The present invention relates to the technical field of environmental assessment, and in particular to a method, device, computer equipment and storage medium for quantitatively assessing environmental risks. Background Art

[0002] Guidelines for Enterprise Sudden Environmental Incident Risk Assessment (Trial) Environmental risk assessment refers to an assessment method that quantitatively analyzes the ratio of the quantity of all environmental risk substances produced, processed, used, and stored by the enterprise to their critical quantity (Q), evaluates the process and environmental risk control level (M) and the sensitivity of environmental risk receptors (E), and divides the enterprise's sudden environmental incident risk (hereinafter referred to as environmental risk) level according to the matrix method. This scheme has the following shortcomings.

[0003] 1. Environmental risk assessment requires a lot of information and processes to be collected, and the workload is large. The staff is overloaded with work and the work efficiency is low.

[0004] 2. Under the traditional manual method, once one of the factors of environmental risk assessment changes, the entire calculation process needs to be adjusted manually, and the calculation process is complicated and prone to errors.

[0005] 3. It is difficult to formulate detailed control measures for environmental risks. Although quantitative environmental risk assessment results can be calculated manually, it is impossible to determine which factor is responsible based on the quantitative calculation formula when formulating downgrade control measures for classified environmental risks. This is still a time-consuming process that requires the accumulation of expert knowledge.

[0006] 4. There is a lot of data in the risk assessment process, and it is difficult to retain the assessment ledger and process records. Many process records often share the same material, which makes it inconvenient to trace the assessment results. Summary of the invention

[0007] In view of this, the present invention provides a method, apparatus, computer device and storage medium for quantitatively assessing environmental risks to solve the problem that the risk level cannot be quantitatively assessed when assessing environmental risks.

[0012] The actual comprehensive environmental risk index is calculated based on the real-time acquisition of the ratio of the number of environmental risk substances in the risk source to the critical value, the evaluation of the process and the environmental risk control level and the sensitivity of the environmental risk receptor. The actual comprehensive environmental risk index is matched with the corresponding comprehensive environmental risk index and the corresponding risk level standard to quantitatively evaluate the risk level of the risk source.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0049] The petrochemical industry is a pillar industry for national economic and social development, and is also a key industry for pollutant emissions. The Ministry of Ecology and Environment has issued the "Guidelines for Risk Assessment of Sudden Environmental Events in Enterprises (Trial)", which aims to establish and improve the technical standard system for environmental risk assessment and control of chemical substances, and promote the identification and control of environmental risks. At present, the future development direction of the petrochemical industry is intelligent and green. Therefore, the market prospects for configurable quantitative environmental risk assessment products for the petrochemical industry are broad.

[0050] Enterprises can rely on informatization and enterprise environmental risk assessment. The current operations are: extracting relevant information and identifying relevant information about environmental risks, analyzing possible sudden environmental events and their consequences, analyzing the gap between existing environmental risk prevention and control and environmental emergency management, formulating and improving the implementation plan of environmental risk prevention and control and emergency measures, and defining the risk level of sudden environmental events. On the basis of collecting relevant information, environmental risk identification is carried out. The objects of environmental risk identification include: 1) basic information of the enterprise; 2) surrounding environmental risk receptors; 3) substances and quantities involved in environmental risks; 4) production processes; 5) production safety management; 6) environmental risk units and existing environmental risk prevention and control and emergency measures; 7) existing emergency resources, etc. It is difficult to formulate detailed control measures for environmental risks based on a large number of risk assessment materials. Although quantitative environmental risk assessment results can be calculated by manual calculation, for the formulation of downgrade control measures for graded environmental risks, it is still a process that requires expert knowledge to determine which factor causes the ratio of the amount of environmental risk substances to their critical amount R, the assessment process and the environmental risk control level M, and the sensitivity of the environmental risk receptor E value, according to the quantitative calculation formula.

[0051] The embodiment of the present invention provides a method for quantitatively assessing environmental risks. By sorting out and solidifying the ratio R of the quantity of all environmental risk substances produced, processed, used, and stored by the enterprise to their critical quantity, the calculation process of the assessment process and the environmental risk control level M, and the sensitivity E of the environmental risk receptor, data interaction and risk classification and clustering are performed according to the affiliation, type level and other information between environmental sensitive target protection, environmental risk online assessment, hidden danger control and sudden environmental event management, thereby achieving the effect of quantitatively assessing the risk level of risk sources.

[0052] According to an embodiment of the present invention, an embodiment of a method for quantitatively assessing environmental risks is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0053] In this embodiment, a method for quantitatively assessing environmental risks is provided, which can be used in the above-mentioned computer terminal, such as a central processing unit, a server, etc., and software for building a risk assessment model is installed on the central processing unit or the server, and the display page is a risk assessment model configuration page. Figure 1 is a flow chart of a method for quantitatively assessing environmental risks according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0054] Step S101, selecting the ratio of the amount of environmental risk substances in the risk source to the critical value, the evaluation process and the environmental risk control level and the sensitivity of the environmental risk receptor as evaluation indicators.

[0055] Specifically, risk sources include water environment and atmospheric environment. Taking atmospheric environmental risk sources as an example, environmental risk substances include toxic gases, such as phosgene, ethylene ketone, hydrogen selenide, oxygen difluoride, arsine, formaldehyde, ethanedinitrile, fluorine, etc. The ratio of the amount of environmental risk substances to the critical value is represented by R, which refers to the ratio of the actual storage amount of environmental risk substances to their critical amount under specific conditions. The ratio R is used to assess the potential risks of environmental risk substances.

[0056] Taking toxic gases as an example, the information included in the ratio R of the number of environmental risk substances to the critical value needs to be entered on the risk model configuration page, including the name of the toxic gas, the CAS number (Chemical Abstracts Service, a chemical substance registration number consisting of a set of numbers used to uniquely identify each chemical substance) corresponding to the toxic gas, and the critical value of the toxic gas.

[0057] The level of control over process and environmental risks is represented by M, which refers to the degree of control over environmental risks in the production process, including production safety control, water environment risk prevention and control measures, atmospheric environment risk prevention and control measures, implementation of other environmental risk prevention and control measures approved by the environmental impact assessment, and wastewater discharge destinations.

[0058] Environmental risk receptor sensitivity is represented by E, which refers to the degree of response of the ecosystem to external disturbances, including its resistance, stability, adaptability, etc. In environmental risk assessment, ecological sensitivity analysis is an important link in evaluating the impact of different sources of disturbance on the ecosystem, aiming to determine the scope and intensity of environmental risks and formulate corresponding countermeasures.

[0059] Step S102, setting the risk level of the ratio of the amount of environmental risk substances to the critical value, the risk level of the assessment process and the environmental risk control level, and the risk level of the sensitivity of the environmental risk receptor based on the preset classification standard.

[0060] Specifically, the preset classification standards are formulated according to the "Enterprise Sudden Environmental Event Risk Classification Method" (HJ941-2018), "High Hydrogen Sulfide Gas Field Gathering and Transportation Pipeline Safety Regulations" (SY6780-2010) and "Environmental Protection Comprehensive Directory (2021 Edition)". The "Enterprise Sudden Environmental Event Risk Classification Method" (HJ 941-2018), "High Hydrogen Sulfide Gas Field Gathering and Transportation Pipeline Safety Regulations" (SY6780-2010) and "Environmental Protection Comprehensive Directory (2021 Edition)" solidify the number and critical amount of risk substances, sudden atmospheric environmental event risk classification and sudden water environmental event risk classification calculation methods, covering the environmental risk regulations of industries such as petrochemicals and oil and gas extraction. The ratio of the number of environmental risk substances to the critical value R risk level is set according to the actual risk substances. The risk level M for evaluating the process and environmental risk control level and the sensitivity of the environmental risk receptor E are set according to the actual environment. The evaluation of the process and environmental risk control level M is calculated using the scores of indicators such as production process hazard, process compliance and safety management.

[0061] Step S103, using the index calculation method to arrange and combine the risk level of the ratio of the quantity of each environmental risk substance to the critical value, the risk level of each assessment process to the environmental risk control level, and the risk level of each environmental risk receptor sensitivity to obtain a risk assessment model, and calculate the comprehensive environmental risk index of the risk assessment model and the corresponding risk level standard.

[0062] Specifically, the index calculation method refers to a method of calculation using an exponential function, and permutations and combinations are used to study the total number of possible permutations and combinations of given requirements. The index calculation method is used to permute and combine the risk level of the ratio of each environmental risk substance quantity to the critical value, the risk level of each assessed process to the environmental risk control level, and the risk level of each environmental risk receptor sensitivity to obtain a risk assessment model, and calculate the comprehensive environmental risk index of the risk assessment model and the corresponding risk level standard.

[0063] Step S104, calculates the actual comprehensive environmental risk index based on the real-time acquisition of the ratio of the number of environmental risk substances in the risk source to the critical value, the evaluation of the process and the environmental risk control level and the sensitivity of the environmental risk receptor, matches the actual comprehensive environmental risk index with the corresponding comprehensive environmental risk index and the corresponding risk level standard, and quantitatively evaluates the risk level of the risk source.

[0064] Specifically, taking the water gas station as an example, the environmental risk substances involved in the water gas station and the corresponding ratio of the number of environmental risk substances to the critical value, the evaluation process and the value of the environmental risk control level and the risk receptor sensitivity are obtained in real time. The environmental risk substances involved in the water gas station and the corresponding ratio of the number of environmental risk substances to the critical value, the evaluation process and the value of the environmental risk control level and the risk receptor sensitivity are input into the risk assessment model, and the corresponding comprehensive environmental risk index and the corresponding risk level standard of the corresponding assessment matrix are found to achieve the purpose of quantitatively assessing the risk level of the risk source.

[0065] The quantitative environmental risk assessment method provided in this embodiment organizes and solidifies the ratio R of the quantity of all environmental risk substances produced, processed, used, and stored by the enterprise to their critical quantity, the evaluation process and the environmental risk control level M, and the calculation process of the environmental risk receptor sensitivity E. The algorithm built into the software will perform data interaction and risk classification clustering based on the affiliation, type level and other information between environmental sensitive target protection, online environmental risk assessment, hidden danger control and sudden environmental event management to obtain a risk assessment model. Based on the risk assessment model and with the help of environmental protection maps, major environmental risk sources are located, analyzed, and downgraded, achieving the application effect of rapid identification of environmental risks, quantitative assessment, efficient query, and continuous tracking, providing a basis for targeted downgrade management and control of environmental risks, and solving the problem of not being able to quantitatively assess risk levels when assessing environmental risks.

[0066] In this embodiment, a method for quantitatively assessing environmental risks is provided, which can be used in a computer terminal, such as a central processing unit, a server, etc., on which software for building a risk assessment model is installed, and a display page is a risk assessment model configuration page. Figure 2 is a flow chart of a method for quantitatively assessing environmental risks according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0067] Step S201, selecting the ratio of the amount of environmental risk substances in the risk source to the critical value, the evaluation process and the environmental risk control level and the sensitivity of the environmental risk receptor as evaluation indicators.

[0068] Specifically, the above step S201 includes:

[0069] Step S2011, when the risk source includes an environmental risk substance, directly calculate the ratio of the amount of the environmental risk substance to the critical value.

[0070] Specifically, when there is only one environmental risk substance in the risk source, the ratio of the quantity of the environmental risk substance to the critical value is directly calculated, that is, R = q1 / Q1, q1 represents the maximum stock of the environmental risk substance, and Q1 represents the critical value of the environmental risk substance.

[0071] Step S2012, when the risk source includes multiple environmental risk substances, calculate the ratio of the quantity of each environmental risk substance to the critical value and then add them up to obtain the ratio of the quantity of the environmental risk substance to the critical value.

[0072] Specifically, if the risk source includes multiple environmental risk substances, the ratio R of the number of environmental risk substances to the critical value is calculated according to the following formula:

[0073] R=q1 / Q1+q2 / Q2+…+qn / Qn(1);

[0074] Among them, q1, q2, …, qn represent the maximum stock of each environmental risk substance, and Q1, Q2, …, Qn represent the critical value of each environmental risk substance.

[0075] Step S202, setting the risk level of the ratio of the amount of environmental risk substances to the critical value, the risk level of the assessment process and the environmental risk control level, and the risk level of the sensitivity of the environmental risk receptor based on the preset classification standard.

[0076] Specifically, the above step S202 includes:

[0077] Step S2021, setting the upper and lower limit value ranges of the risk level of the ratio of the amount of environmental risk substances to the critical value in sections based on the preset grading standard to obtain multiple risk levels of the ratio of the amount of environmental risk substances to the critical value.

[0078] Specifically, taking the water gas station as an example, the risk level R of the ratio of the number of environmental risk substances to the critical value is set according to the preset grading standards. The upper and lower limits of the R1 risk level are 0≤R1<50, the upper and lower limits of the R2 risk level are 50≤R2<100, and the upper and lower limits of the R3 risk level are 100≤R3<150, etc.

[0079] Step S2022, setting the upper and lower limit ranges of the risk levels of the assessed process and environmental risk control levels in sections based on the preset grading standards to obtain multiple risk levels of the assessed process and environmental risk control levels.

[0080] Specifically, the process and environmental risk control level M is calculated using the production process hazard, process compliance, and safety management scores. The risk model configuration page is used for input, the production process hazard index score is 5 points, and the evaluation basis is whether the refueling (gas, hydrogen) station is enabled. If enabled, the process and environmental risk control level M = 5 points; the production compliance index score is 5 points, and the evaluation basis is whether the process list and equipment that have been eliminated within a time limit stipulated by the state are enabled. If enabled, the process and environmental risk control level M = 5 points. If the above situation does not exist, the process and environmental risk control level M = 0. The safety management index score is 10 points. The assessment basis is whether the major or major production safety accident hazards that may cause sudden environmental incidents have not been rectified. If enabled, the process and environmental risk control level M is assessed at 10 points. Whether the general production safety accident hazards that may cause sudden environmental incidents have not been rectified, each item is scored 7 points, until the maximum score is reached. If enabled, the process and environmental risk control level is assessed at M = 0 to 10 points. If the above problems do not exist, the process and environmental risk control level is assessed at M = 0.

[0081] Step S2023, setting the upper and lower limits of the environmental risk receptor sensitivity risk level in sections based on the preset grading standard to obtain multiple environmental risk receptor sensitivity risk levels.

[0082] Taking a water gas station or a car gas station as an example, the risk level of environmental risk receptor sensitivity E is set according to the preset classification standard, which can be described as follows: the assessment indicator is the situation of drinking water-related water environmental risk receptors, and the assessment scope is within the range of 10km downstream of the discharge outlet of the factory (field, station) area of ​​the risk source enterprise or the discharge point where the risk substance may leak into the inland water body, and within twice the maximum horizontal distance that the water quality point in a lake cycle in the nearshore sea area may reach. The assessment basis includes:

[0083] ① The assessment scope involves centralized drinking water sources or water source protection areas in cities above the municipal level, at which time the environmental risk receptor sensitivity E = 50 points; ② The assessment scope involves centralized drinking water sources or water source protection areas in county-level cities, at which time the environmental risk receptor sensitivity E = 40 points; ③ The assessment scope involves centralized drinking water sources or water source protection areas in townships, at which time the environmental risk receptor sensitivity E = 30 points; ④ The assessment scope involves rural and decentralized drinking water sources or water source protection areas, at which time the environmental risk receptor sensitivity E = 20 points; ⑤ It does not involve situations ① to ④, at which time the environmental risk receptor sensitivity E = 0. Step S203, using the index calculation method to arrange and combine the risk level of the ratio of the quantity of each environmental risk substance to the critical value, the risk level of each assessment process to the environmental risk control level, and the risk level of each environmental risk receptor sensitivity to obtain a risk assessment model, and calculate the comprehensive environmental risk index of the risk assessment model and the corresponding risk level standard.

[0084] Specifically, the above step S203 includes:

[0085] Step a. Use the index calculation method to arrange and combine the risk level of the ratio of the quantity of each environmental risk substance to the critical value and the upper and lower limits corresponding to the risk level, the risk level of each assessment process and the environmental risk control level and the upper and lower limits corresponding to the risk level, and the risk level of each environmental risk receptor sensitivity and the upper and lower limits corresponding to the risk level to obtain multiple assessment matrices, summarize the multiple assessment matrices to obtain a risk assessment model, and calculate the comprehensive environmental risk index and the corresponding risk level standard of each assessment matrix in the risk assessment model.

[0086] The index calculation method is used to arrange and combine the risk levels R1, R2, …, Rw and the corresponding score range of the ratio R of the number of environmental risk substances to the critical value, the risk levels M1, M2, …, Mw and the corresponding score range of the evaluation process and environmental risk control level M, and the risk levels E1, E2, …, Ew and the corresponding score range of the environmental risk receptor sensitivity E to obtain a risk matrix after each combination. After summarizing multiple risk matrices, a risk assessment model is obtained and stored in a structured database (a type of database that organizes and stores data in a predefined pattern (such as tables, rows and columns)).

[0087] In an optional implementation, the step a. of calculating the comprehensive environmental risk index and the corresponding risk level standard of each assessment matrix in the risk assessment model includes:

[0088] Calculate the upper and lower limits corresponding to the risk level of the ratio of the quantity of each environmental risk substance to the critical value, the upper and lower limits corresponding to the risk level of each assessed process and the environmental risk control level, and the upper and lower limits corresponding to the risk level of each environmental risk receptor sensitivity. Multiply the cube root of these numbers by the preset environmental correction coefficient to obtain the comprehensive environmental risk index and the corresponding risk level standard.

[0089] The water environment risk index is represented by Sw, the atmospheric environment risk index is represented by Sa, and the preset environmental correction coefficients include the water environment correction coefficient α and the atmospheric environment correction coefficient β. The expression of the comprehensive environmental risk index can be expressed as:

[0090]

[0091] Among them, the comprehensive environmental risk index S includes 5 levels, and the upper and lower limits of the 5 levels are from high to low: 10000≤S1<200, and the corresponding risk level standard is extremely high; 100≤S2<200, and the corresponding risk level standard is high; 50≤S3<100, and the corresponding risk level standard is relatively high; 10≤S4<50, and the corresponding risk level standard is medium; 0≤S5<10, and the corresponding risk level standard is low.

[0092] Step S204, based on the real-time acquisition of the ratio of the amount of environmental risk substances in the risk source to the critical value, the evaluation of the process and the environmental risk control level and the sensitivity of the environmental risk receptor, the actual comprehensive environmental risk index is calculated, and the actual comprehensive environmental risk index is matched with the corresponding comprehensive environmental risk index and the corresponding risk level standard to quantitatively evaluate the risk level of the risk source. For details, please refer to Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0093] The environmental risk quantitative assessment method provided in this embodiment calculates the ratio of the number of environmental risk substances to the critical value according to the types of environmental risk substances in the risk source, thereby achieving the purpose of accurately calculating the ratio of the number of environmental risk substances to the critical value, thereby indirectly improving the accuracy of subsequent environmental risks. The preset grading standard sets the upper and lower limit value ranges of the risk level of the ratio of the number of environmental risk substances to the critical value, the upper and lower limit value ranges of the risk level of the assessment process and the environmental risk control level, and the upper and lower limit value ranges of the risk level of the environmental risk receptor sensitivity in sections, and quantitatively assesses the risk level of each assessment indicator. Considering all situations after the permutations and combinations of the risk level of each environmental risk substance ratio and the upper and lower limits of the risk level, each assessment process and environmental risk control level risk level and the upper and lower limits of the risk level, and each environmental risk receptor sensitivity risk level and the upper and lower limits of the risk level, the integrity and accuracy of the obtained risk assessment model is ensured.

[0094] In this embodiment, a method for quantitatively assessing environmental risks is provided, which can be used in a computer terminal, such as a central processing unit, a server, etc., on which software for building a risk assessment model is installed, and a display page is a risk assessment model configuration page. Figure 3 is a flow chart of a method for quantitatively assessing environmental risks according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0095] Step S301, select the ratio of the amount of environmental risk substances in the risk source to the critical value, the evaluation process and the environmental risk control level and the sensitivity of the environmental risk receptor as evaluation indicators. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0096] Step S302: Set the risk level of the ratio of the amount of environmental risk substances to the critical value, the risk level of the process and environmental risk control level, and the risk level of the sensitivity of the environmental risk receptor based on the preset classification standard. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0097] Step S303: Use the index calculation method to arrange and combine the risk level of the ratio of the quantity of each environmental risk substance to the critical value, the risk level of each assessed process to the environmental risk control level, and the risk level of each environmental risk receptor sensitivity to obtain a risk assessment model, and calculate the comprehensive environmental risk index of the risk assessment model and the corresponding risk level standard. For details, please refer to Figure 2 Step S203 of the illustrated embodiment will not be described in detail here.

[0098] Step S304, calculates the actual comprehensive environmental risk index based on the real-time acquisition of the ratio of the number of environmental risk substances in the risk source to the critical value, the evaluation of the process and the environmental risk control level and the sensitivity of the environmental risk receptor, matches the actual comprehensive environmental risk index with the corresponding comprehensive environmental risk index and the corresponding risk level standard, and quantitatively evaluates the risk level of the risk source.

[0099] Specifically, the above step S304 includes:

[0100] Step b. Match the actual comprehensive environmental risk index with the comprehensive environmental risk index corresponding to each assessment matrix and the corresponding risk level standard to quantitatively assess the risk level of the risk source.

[0101] Specifically, taking the water gas station as an example, the environmental risk substances involved in the water gas station and the corresponding ratio of the number of environmental risk substances to the critical value, the evaluation process and the environmental risk control level and the value of the environmental risk receptor sensitivity are obtained in real time; the environmental risk substances involved in the water gas station and the corresponding ratio of the number of environmental risk substances to the critical value, the evaluation process and the environmental risk control level and the value of the risk receptor sensitivity are input into the corresponding risk assessment matrix, the corresponding comprehensive environmental risk index and the corresponding risk level standard are found, so as to achieve the purpose of quantitatively evaluating the risk level of the risk source.

[0102] Step S305, when the actual comprehensive environmental risk index does not match the corresponding comprehensive environmental risk index and the corresponding risk level standard, the real-time acquired ratio of the amount of environmental risk substances in the risk source to the critical value, the assessment process and the environmental risk control level and the sensitivity of the environmental risk receptor are added as a new assessment matrix as well as the actual comprehensive environmental risk index and the corresponding risk level standard to the structured database to update the structured database.

[0103] Updating the structured database realizes real-time updating of the structured database, ensures the integrity of the structured data, provides conditions for quantitative assessment of the risk level of risk sources, breaks the traditional model of "focusing on emergency response and neglecting prevention", and builds a modern comprehensive environmental risk management and control system.

[0104] The environmental risk quantitative assessment method provided in this embodiment matches the actual comprehensive environmental risk index with the comprehensive environmental risk index and the corresponding risk level standard corresponding to each assessment matrix, quantitatively assesses the risk level of the risk source, and reads the corresponding comprehensive environmental risk index and the corresponding risk level standard in the structured data, so as to achieve the application effect of rapid identification and quantitative assessment of environmental risks, efficient query, and continuous tracking. The structured database is updated to achieve real-time update of the structured database, ensure the integrity of the structured data, provide conditions for quantitative assessment of the risk level of the risk source, break the traditional mode of "focusing on emergency response and neglecting prevention", and build a modern all-round environmental risk management and control system.

[0105] As one or more specific application embodiments of the embodiments of the present invention, the environmental risk quantitative assessment method provided by the present invention is further described in detail as follows:

[0106] Taking a sewage plant pipeline in the water environment as an example, after the risk is discovered, the amount of environmental risk substance R is entered in the risk assessment model configuration page. The environmental risk substance is organic waste liquid with a CODCr concentration ≥ 10000 mg / L, and the total amount is 87 tons.

At the same time, the assessment process and environmental risk control level M are filled in with relevant hazard, compliance and other information, and the assessment process and environmental risk control level M is 25. The comprehensive environmental risk index S value is calculated by combining the R value, M value, E value and the water environment correction coefficient α, and the calculation result is S=144.07. The query S value is between 100≤S2<200, and the corresponding risk level standard is high, that is, the final risk level assessment result of a sewage plant pipeline is high.
