Description

Technical Field

[0001] The present invention relates to the technical field of ozone pollution emission management, and in particular to an air pollution emission allocation method based on environmental quality improvement. Background Art

[0002] To achieve effective pollution control, improve air quality, and promote green development, the application of air pollution emission allocation methods can ensure the scientific allocation and implementation of emission control and environmental improvement tasks. By applying scientific air pollution emission allocation methods within industrial parks, not only can the pollution emission problems within the park be effectively resolved, but it can also promote the development of the green economy while improving air quality, achieving a win-win situation for environmental protection and economic development.

[0003] Existing air pollution emission allocation methods primarily achieve precise emission allocation through scientific assessment systems, data analysis, and model prediction. First, achieving air pollution emission allocation requires the collection and analysis of extensive data on environmental quality, emission sources, and meteorology. Based on this collected data, air pollution can be predicted and assessed using environmental quality assessment models. For example, pollutant diffusion models can simulate the diffusion of pollutants from their sources into the atmosphere, helping to analyze the potential for air quality improvement in different regions. Based on the results of the environmental quality assessment, reasonable emission allocation methods are then designed and adjusted in real time using the allocation model. Furthermore, to achieve more precise emission allocation, optimization algorithms can be used to assist decision-making. For example, based on multiple objectives such as environmental quality improvement, economic benefits, and social justice, multi-objective optimization algorithms such as genetic algorithms and simulated annealing can be used to achieve more precise air pollution emission allocation.

[0004] For example, the invention patent announcement with announcement number: CN114548790B discloses a method, device and related components for allocating carbon emissions from an integrated energy system, including: obtaining data on each uncertain factor, assigning different scenario deviation coefficients to the data on each uncertain factor, obtaining updated data on the uncertain factors and combining them to form different combination scenarios; using a genetic algorithm to calculate the values of the objective functions corresponding to each task under each combination scenario to obtain the optimal target planning; and allocating carbon emissions based on a pre-constructed carbon emission flow model and the optimal target planning.

[0005] For example, the pollution emission control method, device and storable medium disclosed in the invention patent announcement with announcement number CN112581107B include: obtaining forecast air information for a region, the forecast air information including the type of air pollution; obtaining pollution emission data of each enterprise in the region, and determining the pollution emission type of each enterprise; the pollution emission data includes sulfur dioxide concentration, nitrogen dioxide concentration, carbon monoxide concentration, PM2.5 concentration and PM10 concentration; and performing emission control on target enterprises in the region, and the pollution emission type of the target enterprise corresponds to the air pollution type.

[0006] However, in the process of implementing the technical solutions of the invention in the embodiments of the present application, the present application found that the above technology has at least the following technical problems:

[0007] Industrial parks are significant sources of nitrogen oxide and volatile organic compound emissions. Ozone formation depends on the interaction between nitrogen oxides and volatile organic compounds, a relationship influenced by many factors. Under haze conditions, the chemical reaction rate, diffusion, and deposition of nitrogen oxides and volatile organic compounds are also affected by meteorological conditions. For example, under conditions of stagnant atmospheric circulation, the accumulation of pollutants can exacerbate haze formation, leading to a delayed onset of ozone pollution.

[0008] Another consideration is that meteorological conditions vary significantly during haze weather, and their impact on pollutants is complex and variable. Factors such as temperature, wind speed, atmospheric stability, and solar radiation indirectly or directly affect ambient air quality by altering the diffusion, reaction rates, and deposition of pollutants (such as ozone). Under haze weather conditions, these factors often lead to pollutant accumulation and further exacerbate pollution. Consequently, the allocation of nitrogen oxide and volatile organic compound emissions from industrial parks during haze weather is insufficiently correlated with ozone pollution. Summary of the Invention

[0012] Furthermore, the specific process of executing the ozone generation pollution emission allocation adjustment is as follows: after executing the ozone emission allocation judgment update, the ozone precursor pollutant concentration data in the industrial park is obtained. The ozone emission allocation judgment update means updating the ozone emission threshold to the ozone emission judgment threshold according to the emission judgment update threshold strength. The ozone precursor pollutant concentration data includes meteorological pollution interference data and ozone precursor concentration data; the emission judgment update threshold strength means inputting the degree of deviation between the ozone emission concentration and the ozone emission threshold into the emission judgment threshold mapping set in the preset database for mapping. The emission judgment threshold mapping set is established with ozone. The mapping relationship between the degree of deviation between emission concentration and ozone emission threshold and the intensity of emission judgment update threshold; based on the ozone precursor pollutant concentration data, the pollution risk level of ozone generation under the interference of haze meteorological light is quantitatively assessed to obtain the ozone generation pollution risk value, which is used to quantitatively assess the pollution risk level of ozone generation under the interference of haze meteorological light; the obtained ozone generation pollution risk value is compared with the preset ozone generation pollution risk judgment range obtained from the preset database to obtain the ozone generation assessment result, which includes ozone generation pollution risk qualified and ozone generation pollution risk warning.

[0014] Furthermore, an ozone generation assessment result is obtained, and the specific steps are as follows: if the obtained ozone generation pollution risk value is not within the preset ozone generation pollution risk determination range obtained from the preset database, the corresponding ozone generation assessment result is recorded as qualified ozone generation pollution risk, and the precursor pollutant emission allocation optimization is not performed, and it is continuously judged whether the ozone generation pollution risk value is within the preset ozone generation pollution risk determination range; if the obtained ozone generation pollution risk value is within the preset ozone generation pollution risk determination range obtained from the preset database, the corresponding ozone generation assessment result is recorded as ozone generation pollution risk warning, and the precursor pollutant emission allocation optimization is performed.

[0015] Furthermore, the specific steps for executing the optimization of precursor pollutant emission allocation are as follows: the ozone emission concentration, the ozone generation pollution risk value and the deviation degree of the reference ozone generation pollution risk threshold are inputted into the nitrogen oxide allocation adjustment mapping set in the preset database for mapping, and the nitrogen oxide emission adjustment strength is obtained. The nitrogen oxide emission adjustment strength is used to update the initial set nitrogen oxide emission of the pollution source to obtain the set nitrogen oxide emission. If the nitrogen oxide emission of the pollution source is greater than the obtained set nitrogen oxide emission, a stop nitrogen oxide emission instruction is sent. Otherwise, the nitrogen oxide emission of the pollution source is continuously monitored. The set emission volume is used to describe the maximum nitrogen oxide emission volume that the pollution source can emit after the initial set nitrogen oxide emission volume of the pollution source is updated with the nitrogen oxide emission regulation intensity. The nitrogen oxide allocation regulation mapping set establishes a mapping relationship between the ozone emission concentration and the degree of deviation of the ozone generation pollution risk value and the nitrogen oxide emission regulation intensity; the ozone emission concentration, the ozone generation pollution risk value and the degree of deviation of the reference ozone generation pollution risk threshold are input into the volatile organic compound allocation regulation mapping set in the preset database for mapping to obtain the volatile organic compound emission regulation intensity, and the volatile organic compound emission regulation intensity is obtained.

If the volatile organic compound emission amount of the pollution source is greater than the obtained set emission amount of volatile organic compounds, a stop volatile organic compound emission instruction is sent. Otherwise, the volatile organic compound emission amount of the pollution source is continuously monitored. The set emission amount of volatile organic compounds is used to describe the maximum volatile organic compound emission amount of the pollution source after the initial set emission amount of volatile organic compounds of the pollution source is updated with the intensity of volatile organic compound emission regulation.

The adjustment collection frequency represents the result of mapping the ozone generation pollution risk value into the monitoring collection mapping set in the preset database. The monitoring collection mapping set establishes a mapping relationship between the ozone generation pollution risk value and the adjustment collection frequency.

[0016] Furthermore, the specific process for adjusting the allocation of ozone diffusion pollution emissions is as follows: determine whether the degree of deviation between the ozone emission concentration and the ozone emission threshold is within the preset ozone pollution controllable range obtained from the preset database; if the degree of deviation between the ozone emission concentration and the ozone emission threshold is within the preset ozone pollution controllable range, obtain the ozone diffusion quantitative data in the industrial park; otherwise, send an instruction to stop the emission of ozone precursor pollutants; based on the ozone diffusion quantitative data, evaluate the pollution risk level of ozone diffusion under the interference of haze meteorological inversion to obtain an ozone diffusion pollution risk value, which is used to quantitatively evaluate the pollution risk level of ozone diffusion under the interference of haze meteorological inversion; combine the preset ozone diffusion pollution risk judgment range obtained from the preset database, compare and judge the obtained ozone diffusion pollution risk values, and obtain the ozone diffusion assessment results, which include normal ozone diffusion and ozone diffusion warning.

[0027] The embodiments of the present application solve the problem in the prior art of insufficient correlation between the emission allocation of nitrogen oxide emissions and volatile organic compound emissions in industrial parks under haze weather and ozone pollution by providing an air pollution emission allocation method based on environmental quality improvement. The ozone emission pollution judgment result is obtained based on the ozone emission concentration in the industrial park, and it is determined whether to perform ozone generation pollution emission allocation adjustment. If ozone generation pollution emission allocation adjustment is performed, the ozone precursor pollutant concentration data in the industrial park is obtained after the ozone emission allocation judgment update is performed to evaluate the pollution risk level of ozone generation under haze weather light interference, and then the obtained ozone generation assessment result is combined to determine whether to perform precursor pollutant emission allocation optimization. If ozone generation pollution emission allocation adjustment is not performed, the pollution risk level of ozone diffusion under haze weather inversion interference is evaluated after the ozone concentration deviation judgment is performed, and then the obtained ozone diffusion assessment result is combined to determine whether to perform ozone diffusion emission allocation optimization, thereby effectively improving the rationality of the emission allocation of nitrogen oxide emissions and volatile organic compound emissions in industrial parks under haze weather.

[0028] The technical solution in the embodiments of the present application is to solve the problem of insufficient correlation between the emission distribution of nitrogen oxide emissions and volatile organic compound emissions in industrial parks and ozone pollution under the above-mentioned haze weather. The overall idea is as follows:

[0029] The ozone emission pollution judgment result is used to determine whether to implement ozone generation pollution emission allocation adjustment. If implemented, the ozone generation assessment result is combined to determine whether to implement precursor pollutant emission allocation optimization. Otherwise, the ozone diffusion assessment result is combined to determine whether to implement ozone diffusion emission allocation optimization, thereby achieving the effect of improving the rationality of emission allocation of nitrogen oxides and volatile organic compound emissions in industrial parks under haze weather conditions.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] like Figure 1As shown, it is a flow chart of an air pollution emission allocation method based on environmental quality improvement provided by an embodiment of the present application, the method comprising the following steps: obtaining an ozone emission pollution judgment result based on the ozone emission concentration in the industrial park, and judging whether to execute ozone generation pollution emission allocation adjustment; if ozone generation pollution emission allocation adjustment is executed, then obtaining ozone precursor pollutant concentration data in the industrial park after executing the ozone emission allocation judgment update to evaluate the pollution risk degree of ozone generation under the interference of haze weather and light, and judging whether to execute precursor pollutant emission allocation optimization based on the obtained ozone generation evaluation result, and precursor pollutant emission Allocation optimization means allocating nitrogen oxide emissions and volatile organic compound emissions in combination with the ozone generation assessment results to improve the impact of ozone generation pollution risk on environmental quality; if ozone generation pollution emission allocation adjustment is not performed, the pollution risk level of ozone diffusion under the interference of haze meteorological inversion is evaluated after the ozone concentration deviation judgment is performed, and the ozone diffusion assessment results obtained are combined to determine whether to perform ozone diffusion emission allocation optimization. Ozone diffusion emission allocation optimization means allocating nitrogen oxide emissions and volatile organic compound emissions in combination with the ozone diffusion assessment results to improve the impact of ozone diffusion pollution risk on environmental quality.

[0032] like Figure 2 As shown, it is a structural flow chart of the air pollution emission allocation method based on environmental quality improvement provided in an embodiment of the present application, and the corresponding logic is: based on the ozone emission concentration, it is determined whether to execute ozone generation pollution emission allocation adjustment; if ozone generation pollution emission allocation adjustment is executed, the pollution risk degree of ozone generation under the interference of haze weather light is evaluated to obtain an ozone generation pollution risk value; based on the ozone generation pollution risk value, an ozone generation assessment result is obtained; and according to the ozone generation assessment result, it is determined whether to execute precursor pollutant emission allocation optimization; if ozone generation pollution emission allocation adjustment is not executed, the pollution risk degree of ozone diffusion under the interference of haze weather inversion is evaluated to obtain an ozone diffusion pollution risk value; based on the ozone diffusion pollution risk value, an ozone diffusion assessment result is obtained; and according to the ozone diffusion assessment result, it is determined whether to execute ozone diffusion emission allocation optimization.

[0033] In this embodiment, with the acceleration of industrialization, especially in areas with dense industrial parks, pollutant emissions have become a significant factor affecting air quality, environmental health, and public quality of life. Furthermore, during haze weather conditions, the atmosphere is stable and airflow is weak, making it difficult for pollutants to diffuse and dilute. This leads to their accumulation near the ground, seriously impacting air quality and human health. Ozone pollution is a typical secondary pollution, produced by chemical reactions between nitrogen oxides and volatile organic compounds in the atmosphere. During haze weather, due to poor atmospheric diffusion conditions, concentrations of ozone and other pollutants can reach dangerous levels. Therefore, by analyzing nitrogen oxide and volatile organic compound emissions from industrial parks and accurately allocating these emissions, a theoretical basis can be provided for controlling ozone pollution. Taking measures to reduce the emission of these pollutants can help reduce ozone concentrations and improve air quality. Existing pollutant emission monitoring technologies are not fully adapted to emission allocation and ozone pollution management under complex weather conditions. Researching and developing reliable air pollution emission allocation methods is of great significance for improving environmental quality monitoring capabilities during haze weather. The algorithm in this application analyzes the emission distribution of nitrogen oxides and volatile organic compounds in industrial parks under haze weather and their relationship with ozone pollution, thereby making reasonable emission distribution of corresponding nitrogen oxide emissions and volatile organic compound emissions under different ozone pollution risk levels. This is of great significance for improving environmental quality. It can not only reduce ozone pollution and improve air quality, but also reduce public health risks and promote the development of green technologies.

[0034] Furthermore, it is determined whether to implement the ozone generation pollution emission allocation adjustment. The specific process is as follows:

[0035] First, the ozone emission threshold is obtained from a preset database, and the obtained ozone emission concentration is compared with the ozone emission threshold. Among them, the ozone emission concentration is obtained through the air quality monitoring station, and the ozone emission threshold is set by professionals according to the standards in the field. For example, the ozone emission threshold is set to the maximum value of the ozone emission concentration collected in the historical time period, and the ozone emission concentration collected in the historical time period is not greater than the ozone emission threshold.

[0036] Secondly, if the ozone emission concentration is not greater than the ozone emission threshold, the corresponding ozone emission pollution judgment result will be recorded as qualified ozone emission, the ozone generation pollution emission allocation adjustment will be implemented, and the ozone emission concentration will be continuously monitored.

[0037] It should be added that the specific process for implementing the allocation adjustment of ozone generation pollution emissions is as follows:

[0038] A1. After executing the ozone emission allocation determination update, obtain ozone precursor pollutant concentration data within the industrial park. Ozone precursor pollutant concentration data includes meteorological pollution interference data and ozone precursor concentration data. The ozone emission allocation determination update means updating the ozone emission threshold to the ozone emission determination threshold based on the emission determination update threshold strength.

[0039] Specifically, the emission judgment update threshold strength represents the result of mapping the ozone emission concentration and the degree of deviation from the ozone emission threshold into the emission judgment threshold mapping set in the preset database. The emission judgment threshold mapping set establishes a mapping relationship between the ozone emission concentration and the degree of deviation from the ozone emission threshold and the emission judgment update threshold strength. Specifically, as the degree of deviation from the ozone emission threshold increases, the emission judgment update threshold strength increases accordingly. The degree of deviation from the ozone emission concentration and the ozone emission threshold is the result of the difference calculation between the ozone emission threshold and the ozone emission concentration.

[0040] A2: Based on the concentration data of ozone precursor pollutants, quantitatively assess the pollution risk of ozone formation under the interference of haze weather and light, and obtain the ozone formation pollution risk value. The specific steps for obtaining the ozone formation pollution risk value are as follows:

[0041] A21. Obtain meteorological pollution interference data and ozone precursor concentration data within a preset pollution monitoring period based on the initial monitoring and collection frequency. The meteorological pollution interference data include ultraviolet radiation intensity, haze particle concentration, and meteorological light intensity, and the ozone precursor concentration data include nitrogen oxide concentration and volatile organic compound concentration. Specifically, the meteorological pollution interference data and ozone precursor concentration data are both de-normalized. The meteorological pollution interference data are obtained through air quality monitoring stations. The corresponding ultraviolet radiation intensity reference value, haze particle reference concentration, and meteorological light intensity reference value are represented by averaging the ultraviolet radiation intensity, haze particle concentration, and meteorological light intensity collected within a historical period. The nitrogen oxide concentration and volatile organic compound concentration are obtained through nitrogen oxide sensors and gas chromatographs deployed at the emission outlets of pollution sources. The corresponding nitrogen oxide reference maximum concentration and volatile organic compound reference maximum concentration are represented by the maximum values of the nitrogen oxide concentration and volatile organic compound concentration collected within the historical period.

[0042] A22, the relative deviation of ultraviolet radiation intensity (i.e., the ozone formation meteorological interference factor) Part), relative deviation of haze particle concentration (i.e., the meteorological interference factor of ozone formation part) and relative deviation of meteorological light intensity (i.e., the meteorological interference factor of ozone formation The ozone generation meteorological interference factor is obtained by weighted calculation and coupling through the interference compensation amount obtained from the preset database. The numerical expression of the ozone generation meteorological interference factor is as follows:

[0043] ;

[0044] Where, Indicates the meteorological interference factor of ozone generation within the preset pollution monitoring period. Indicates the meteorological ultraviolet interference compensation amount, represents the compensation amount for meteorological particle interference, Indicates the compensation amount for meteorological light intensity interference, Indicates the ultraviolet radiation intensity during the preset pollution monitoring period. Indicates the reference value of ultraviolet radiation intensity, Indicates the concentration of haze particles within the preset pollution monitoring period. Indicates the reference concentration of haze particles, Indicates the meteorological light intensity during the preset pollution monitoring period. Indicates the meteorological light intensity reference value.

[0045] Among them, the interference compensation amount includes meteorological ultraviolet interference compensation amount, meteorological particle interference compensation amount and meteorological light intensity interference compensation amount. The meteorological ultraviolet interference compensation amount, meteorological particle interference compensation amount and meteorological light intensity interference compensation amount are respectively used to describe the influence of the relative deviation of ultraviolet radiation intensity, the relative deviation of haze particle concentration and the relative deviation of meteorological light intensity on the meteorological interference factor of ozone formation. The sum of the three is 1. The corresponding meteorological ultraviolet interference compensation amount, meteorological particle interference compensation amount and meteorological light intensity interference compensation amount are obtained by inputting the real-time relative deviation of ultraviolet radiation intensity, the relative deviation of haze particle concentration and the relative deviation of meteorological light intensity into the mapping set of preset relative deviation of ultraviolet radiation intensity, relative deviation of haze particle concentration and relative deviation of meteorological light intensity and their corresponding compensation amounts in the database.

[0046] A23, the ozone generation risk weighted coupling result (i.e. the ozone generation pollution risk value Part) is interactively processed with the ozone formation meteorological interference factor for pollution risk meteorological correction to obtain the ozone formation pollution risk value. The ozone formation risk weighted coupling result represents the result of coupling the nitrogen oxide concentration ratio result and the volatile organic compound concentration ratio result with the corresponding risk compensation amount after weighted calculation. The nitrogen oxide concentration ratio result represents the result of ratio calculation of nitrogen oxide concentration and nitrogen oxide reference maximum concentration. The volatile organic compound concentration ratio result represents the result of ratio calculation of volatile organic compound concentration and volatile organic compound reference maximum concentration. The pollution risk meteorological correction interactive processing is used to describe the interaction between the ozone formation risk weighted coupling result and the ozone formation meteorological interference factor, that is, the process of obtaining the numerical expression of the ozone formation pollution risk value. The numerical expression of the ozone formation pollution risk value is as follows:

[0047] ;

[0048] Where, Indicates the ozone generation pollution risk value within the preset generation pollution monitoring period. represents the nitrogen oxide risk compensation amount, represents the risk compensation amount of volatile organic compounds, Indicates the concentration of nitrogen oxides within the preset pollution monitoring period. Indicates the maximum reference concentration of nitrogen oxides, Indicates the concentration of volatile organic compounds within the preset pollution monitoring period. Indicates the reference maximum concentration of volatile organic compounds.

[0049] The risk compensation amount includes the nitrogen oxide risk compensation amount and the volatile organic compound risk compensation amount, the sum of the two is 1 and the value range is 0 to 1. The corresponding nitrogen oxide risk compensation amount and volatile organic compound risk compensation amount are obtained by inputting the real-time nitrogen oxide concentration ratio results and volatile organic compound concentration ratio results into the preset mapping set of nitrogen oxide concentration ratio results and volatile organic compound concentration ratio results and their corresponding compensation amounts in the database.

[0050] It should be understood that the ozone formation pollution risk value is used to quantitatively assess the degree of ozone formation pollution risk under the interference of haze meteorological light. The ozone formation pollution risk value includes the ozone formation meteorological interference factor, nitrogen oxide concentration, and volatile organic compound concentration, which together represent quantitative data for assessing the degree of ozone formation pollution risk under the interference of haze meteorological light. The ozone formation pollution risk value includes multiple parameters, each of which is correlated with each other. The correlation and mutual influence between the various parameters are considered in a quantitative manner. For example, the intensity of ultraviolet radiation has a direct impact on ozone formation because ultraviolet radiation can promote the chemical reaction between nitrogen oxides and volatile organic compounds, thereby producing ozone. Generally speaking, as the intensity of ultraviolet radiation increases, the ozone formation reaction is promoted. When the ultraviolet radiation and light intensity are strong, that is, the ozone formation meteorological interference factor increases, the higher the concentration of nitrogen oxides, the greater the possibility and speed of ozone formation, and the ozone formation pollution risk value increases accordingly. At the same time, the concentration of haze particles often affects the propagation of ultraviolet radiation, which in turn affects the extent of ozone formation. Increased haze concentration reduces the amount of ultraviolet radiation reaching the ground, increasing meteorological interference factors for ozone formation, thereby affecting the ozone formation reaction. Haze particles themselves may also participate in the ozone formation reaction, further enhancing ozone production. Light intensity is closely related to ultraviolet radiation. Increased light intensity generally means increased ultraviolet radiation, which promotes the reaction of nitrogen oxides and volatile organic compounds to form ozone.

[0051] A3 compares the obtained ozone generation pollution risk value with the preset ozone generation pollution risk assessment range obtained from a preset database to obtain an ozone generation pollution risk assessment result. The ozone generation pollution risk assessment results include qualified ozone generation pollution risk and warning ozone generation pollution risk. The preset ozone generation pollution risk assessment range is set by professionals based on standards in the field.

[0052] The ozone generation assessment results are obtained in the following steps:

[0053] A31. If the obtained ozone generation pollution risk value is not within the preset ozone generation pollution risk determination range obtained from the preset database, the corresponding ozone generation assessment result will be recorded as qualified ozone generation pollution risk, and the precursor pollutant emission allocation optimization will not be performed. It will continue to be judged whether the ozone generation pollution risk value is within the preset ozone generation pollution risk determination range.

[0054] A32. If the obtained ozone generation pollution risk value is within the preset ozone generation pollution risk determination range obtained from the preset database, the corresponding ozone generation assessment result is recorded as an ozone generation pollution risk warning, and the precursor pollutant emission allocation optimization is performed.

[0055] Specifically, the specific steps for performing precursor pollutant emission allocation optimization are:

[0056] A321. The ozone emission concentration and the degree of deviation between the ozone generation pollution risk value and the reference ozone generation pollution risk threshold are input into the nitrogen oxide allocation adjustment mapping set in the preset database for mapping to obtain the nitrogen oxide emission adjustment intensity. The reference ozone generation pollution risk value is the average of the ozone generation pollution risk values collected over a historical period, and the degree of deviation between the ozone generation pollution risk value and the reference ozone generation pollution risk threshold is the absolute value of the difference between the ozone generation pollution risk value and the reference ozone generation pollution risk threshold. The initial set nitrogen oxide emissions of the pollution source are updated using the nitrogen oxide emission adjustment intensity to obtain the set nitrogen oxide emissions.

[0057] If the nitrogen oxide emissions from the pollution source are greater than the obtained set nitrogen oxide emissions, an instruction to stop nitrogen oxide emissions is sent; otherwise, the nitrogen oxide emissions from the pollution source are continuously monitored. The set nitrogen oxide emissions are used to describe the maximum nitrogen oxide emissions that the pollution source can emit after the initial set nitrogen oxide emissions of the pollution source are updated with the nitrogen oxide emission regulation intensity. The nitrogen oxide allocation regulation mapping set establishes a mapping relationship between the ozone emission concentration and the degree of deviation from the ozone generation pollution risk value and the nitrogen oxide emission regulation intensity. As the ozone emission concentration and the degree of deviation from the ozone generation pollution risk value increase, the nitrogen oxide emission regulation intensity increases accordingly.

[0058] A322 inputs the ozone emission concentration, the ozone generation pollution risk value and the deviation degree of the reference ozone generation pollution risk threshold into the volatile organic compound allocation adjustment mapping set in the preset database for mapping to obtain the volatile organic compound emission adjustment intensity. The volatile organic compound emission adjustment intensity is used to update the initial set volatile organic compound emission of the pollution source to obtain the set volatile organic compound emission. If the volatile organic compound emission of the pollution source is greater than the obtained set volatile organic compound emission, a stop volatile organic compound emission instruction is sent. Otherwise, the pollution source is continuously monitored. The volatile organic compound emissions, the set volatile organic compound emissions are used to describe the maximum volatile organic compound emissions that the pollution source can emit after the initial set volatile organic compound emissions of the pollution source are updated with the volatile organic compound emission regulation intensity. The volatile organic compound allocation regulation mapping set establishes a mapping relationship between the ozone emission concentration and the degree of deviation from the ozone generation pollution risk value and the volatile organic compound emission regulation intensity. As the degree of deviation from the ozone emission concentration and the ozone generation pollution risk value increases, the volatile organic compound emission regulation intensity increases accordingly.

[0059] A323 collects ozone precursor pollutant concentration data according to the adjusted collection frequency to obtain the secondary ozone generation pollution risk value, and compares and judges the secondary ozone generation pollution risk value with the preset ozone generation pollution risk judgment range. If the secondary ozone generation pollution risk value is within the preset ozone generation pollution risk judgment range, a prompt is sent to indicate the end of the precursor pollutant emission allocation optimization; otherwise, an ozone emission concentration monitoring instruction is sent. The adjusted collection frequency represents the result of mapping the ozone generation pollution risk value into the monitoring and collection mapping set in the preset database. The monitoring and collection mapping set establishes a mapping relationship between the ozone generation pollution risk value and the adjusted collection frequency. As the ozone generation pollution risk value increases, the adjusted collection frequency increases accordingly.

[0060] In addition, if the ozone emission concentration is greater than the ozone emission threshold, the corresponding ozone emission pollution judgment result will be recorded as ozone pollution emission exceeding the standard, the ozone generation pollution emission allocation adjustment will not be performed, and the ozone diffusion pollution emission allocation adjustment will be prompted.

[0061] Specifically, the specific process for adjusting the distribution of ozone diffusion pollution emissions is as follows:

[0062] B1. Determine whether the degree of deviation between the ozone emission concentration and the ozone emission threshold is within the preset ozone pollution controllable range obtained from the preset database. If the degree of deviation between the ozone emission concentration and the ozone emission threshold is within the preset ozone pollution controllable range, obtain the quantitative data of ozone diffusion in the industrial park; otherwise, send an instruction to stop the emission of ozone precursor pollutants; the preset ozone pollution controllable range is set by professionals based on standards in the field.

[0063] B2, based on the ozone diffusion quantitative data, evaluate the pollution risk of ozone diffusion under the interference of haze meteorological inversion and obtain the ozone diffusion pollution risk value. The specific steps to obtain the ozone diffusion pollution risk value are as follows:

[0064] B21. Obtain the quantitative ozone diffusion data for the preset ozone diffusion monitoring period in the industrial park. The quantitative ozone diffusion data includes the average inversion intensity, the average meteorological wind speed, and the ozone concentration. Specifically, the quantitative ozone diffusion data are all de-normalized, and the average inversion intensity and the average meteorological wind speed are obtained from the meteorological observation station, and the ozone concentration is obtained from the ground ozone monitoring station.

[0065] B22, the relative deviation of the average inversion intensity (i.e., the ozone diffusion meteorological interference factor) part) and the relative deviation of the average meteorological wind speed (i.e., the ozone diffusion meteorological interference factor The ozone diffusion meteorological interference factor is obtained by weighted coupling processing with the diffusion interference compensation amount obtained from the preset database. The numerical expression of the ozone diffusion meteorological interference factor is as follows:

[0066] ;

[0067] Where, Indicates the ozone diffusion meteorological interference factor during the preset ozone diffusion monitoring period. represents the compensation for inversion diffusion interference, represents the compensation amount for meteorological wind speed diffusion interference, Indicates the average inversion intensity during the preset ozone diffusion monitoring period. Indicates the reference value of inversion intensity, Indicates the average meteorological wind speed during the preset ozone diffusion monitoring period. Indicates the meteorological wind speed reference value.

[0068] The diffusion interference compensation includes the inversion diffusion interference compensation and the meteorological wind speed diffusion interference compensation. The value range of both is 0 to 1 and the sum is 1. They are respectively used to describe the influence of the average inversion intensity relative deviation and the average meteorological wind speed relative deviation on the ozone diffusion meteorological interference factor. The corresponding inversion diffusion interference compensation and meteorological wind speed diffusion interference compensation are obtained by inputting the real-time average inversion intensity relative deviation and the average meteorological wind speed relative deviation into the preset mapping set of the average inversion intensity relative deviation and the average meteorological wind speed relative deviation and their corresponding compensation amounts in the database.

[0069] B23, after the ozone concentration in the preset ozone diffusion monitoring period is processed by cumulative effect calculation, it is interactively processed with the ozone diffusion meteorological interference factor to obtain the ozone diffusion pollution risk value. The interactive processing of diffusion risk meteorological correction is used to describe the cumulative processing result of ozone concentration (i.e. the ozone diffusion pollution risk value). The interaction between the ozone diffusion part) and the ozone diffusion meteorological interference factor is the process of obtaining the numerical expression of the ozone diffusion pollution risk value. The numerical expression of the ozone diffusion pollution risk value is as follows:

[0070] ;

[0071] Where, Indicates the ozone diffusion pollution risk value during the preset ozone diffusion monitoring period. Indicates any moment in the preset ozone diffusion monitoring time period, , Indicates the time window length of the preset ozone diffusion monitoring period, , Indicates the end time of the preset ozone diffusion monitoring period. Indicates the ozone concentration at time t within the preset ozone diffusion monitoring time period.

[0072] It should be understood that the ozone diffusion pollution risk value represents the quantitative data for assessing the degree of pollution risk of ozone diffusion under the interference of haze meteorological inversion, using the ozone diffusion meteorological interference factor and ozone concentration. It is used to quantitatively assess the degree of pollution risk of ozone diffusion under the interference of haze meteorological inversion. The ozone diffusion pollution risk value takes into account the correlation and mutual influence between various parameters in a quantitative manner. For example, inversion will increase the stability of the atmosphere and limit the vertical diffusion of ozone. The ozone diffusion meteorological interference factor will increase accordingly, which will lead to an increase in ozone concentration, especially in haze weather. The average inversion intensity directly affects ozone diffusion. Inversion will inhibit the vertical diffusion of ozone, causing ozone accumulation at low altitudes and increasing pollution risks. A strong inversion effect will increase ozone concentration, thereby increasing the cumulative treatment results of ozone concentration, and thus increasing the ozone diffusion pollution risk value. In addition, wind speed affects the horizontal diffusion of ozone. Lower wind speeds will cause ozone to be retained in local areas, and the ozone diffusion meteorological interference factor will increase, causing the ozone concentration to increase, increasing the ozone diffusion pollution risk, and thus increasing the cumulative treatment results of ozone concentration, and thus increasing the ozone diffusion pollution risk value.

[0073] B3. Compare and judge the obtained ozone diffusion pollution risk value with the preset ozone diffusion pollution risk assessment range obtained from the preset database to obtain the ozone diffusion assessment result. The ozone diffusion assessment results include normal ozone diffusion and warning ozone diffusion. The preset ozone diffusion pollution risk assessment range is set by professionals based on standards in the field.

[0074] like Figure 3 As shown, it is a flow chart for obtaining ozone diffusion assessment results of the air pollution emission allocation method based on environmental quality improvement provided in an embodiment of the present application. The corresponding logic is: the ozone diffusion pollution risk value is judged by the preset ozone diffusion pollution risk judgment range to obtain the ozone diffusion assessment result. The ozone diffusion assessment result includes normal ozone diffusion and ozone diffusion warning. When the ozone diffusion pollution risk value is not within the preset ozone diffusion pollution risk judgment range, the ozone diffusion assessment result is normal ozone diffusion, and ozone diffusion emission allocation optimization is not performed. It is continuously judged whether the ozone diffusion pollution risk value is within the preset ozone diffusion pollution risk judgment range. When the ozone diffusion pollution risk value is within the preset ozone diffusion pollution risk judgment range obtained from the preset database, the ozone diffusion assessment result is ozone diffusion warning, and ozone diffusion emission allocation optimization is performed. The ozone diffusion pollution emission allocation adjustment reduces the impact of ozone diffusion risk on environmental quality by adjusting the emission of ozone-generating precursor pollutants.

[0075] Specifically, to obtain the ozone diffusion assessment results, the specific steps are as follows:

[0076] B31. If the obtained ozone diffusion pollution risk value is not within the preset ozone diffusion pollution risk determination range obtained from the preset database, the corresponding ozone diffusion assessment result will be recorded as normal ozone diffusion, and ozone diffusion emission allocation optimization will not be performed. It will be continuously determined whether the ozone diffusion pollution risk value is within the preset ozone diffusion pollution risk determination range.

[0077] B32. If the obtained ozone diffusion pollution risk value is within the preset ozone diffusion pollution risk determination range obtained from the preset database, the corresponding ozone diffusion assessment result is recorded as an ozone diffusion warning, and ozone diffusion emission allocation optimization is performed.

[0078] Specifically, the specific steps for performing ozone diffusion emission allocation optimization are:

[0079] B321, input the ozone emission concentration and ozone diffusion pollution risk value into the nitrogen oxide allocation optimization mapping set in the preset database for mapping to obtain the nitrogen oxide emission optimization intensity, and use the nitrogen oxide emission optimization intensity to update the initial set nitrogen oxide emission of the pollution source to obtain the nitrogen oxide optimized emission amount.

[0080] If the nitrogen oxide emissions from the pollution source are greater than the obtained optimized nitrogen oxide emissions, a command to stop nitrogen oxide emissions is sent. Otherwise, the nitrogen oxide emissions from the pollution source are continuously monitored and the secondary ozone diffusion monitoring value is obtained. The secondary ozone diffusion monitoring value represents the ozone diffusion pollution risk value for the next ozone diffusion monitoring period. The optimized nitrogen oxide emissions are used to describe the maximum nitrogen oxide emissions that the pollution source can emit after the initial set nitrogen oxide emissions of the pollution source are updated with the nitrogen oxide emission optimization intensity. The nitrogen oxide allocation optimization mapping set establishes a mapping relationship between the ozone emission concentration and the ozone diffusion pollution risk value and the nitrogen oxide emission optimization intensity. As the ozone emission concentration and the ozone diffusion pollution risk value increase, the nitrogen oxide emission optimization intensity increases accordingly.

[0081] B322, determines whether the secondary ozone diffusion monitoring value is within the preset ozone diffusion pollution risk judgment range. If the secondary ozone diffusion monitoring value is not within the preset ozone diffusion pollution risk judgment range, continue to monitor the ozone diffusion pollution risk value; otherwise, send a command to stop nitrogen oxide emissions.

[0082] B323, input the ozone emission concentration and ozone diffusion pollution risk value into the volatile organic compound allocation optimization mapping set in the preset database for mapping to obtain the volatile organic compound emission optimization intensity, and use the volatile organic compound emission optimization intensity to update the initial set volatile organic compound emission of the pollution source to obtain the optimized volatile organic compound emission.

[0083] If the volatile organic compound emissions from the pollution source are greater than the obtained volatile organic compound set emissions, a volatile organic compound emission stop instruction is sent. Otherwise, the volatile organic compound emissions from the pollution source are continuously monitored and secondary ozone diffusion monitoring values are obtained. The volatile organic compound allocation optimization mapping set establishes a mapping relationship between the ozone emission concentration and the ozone diffusion pollution risk value and the volatile organic compound emission optimization intensity. As the ozone emission concentration and the ozone diffusion pollution risk value increase, the volatile organic compound emission optimization intensity increases accordingly. The volatile organic compound optimized emissions are used to describe the maximum volatile organic compound emissions that the pollution source can emit after the initial set volatile organic compound emissions of the pollution source are updated with the volatile organic compound emission optimization intensity.

[0084] B324, determines whether the secondary ozone diffusion monitoring value is within the preset ozone diffusion pollution risk judgment range. If the secondary ozone diffusion monitoring value is not within the preset ozone diffusion pollution risk judgment range, the ozone diffusion pollution risk value is continuously monitored. Otherwise, a stop volatile organic compound emission instruction is sent. The stop volatile organic compound emission instruction is used to stop the emission of volatile organic compounds from the pollution source.
