Description

Technical Field

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

[0002] In order 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 in industrial parks, not only can the pollution emission problems within the park be effectively solved, but also while improving air quality, it can promote the development of green economy and achieve a win-win situation for environmental protection and economic development.

[0003] Existing air pollution emission allocation methods mainly achieve precise emission allocation through means such as scientific assessment systems, data analysis, and model prediction. First, to achieve air pollution emission allocation, a large amount of data on environmental quality, emission sources, meteorology, etc. must be collected and analyzed. Based on the collected data, air pollution can be predicted and evaluated through an environmental quality assessment model. For example, a pollutant dispersion model can simulate the dispersion process of pollutants from the source to the atmosphere to help analyze the air quality improvement potential in different regions. Then, according to the results of the environmental quality assessment, a reasonable emission allocation method can be designed through an allocation model and adjusted in real time. In addition, to achieve more precise emission allocation, some optimization algorithms can also be used to assist in decision-making. For example, based on multiple objectives such as environmental quality improvement goals, economic benefits, and social justice, multi-objective optimization algorithms such as genetic algorithms and simulated annealing algorithms can be used to achieve more precise air pollution emission allocation.

[0004] For example, a carbon emission allocation method, device, and related components disclosed in the invention patent with the publication number CN114548790B include: obtaining data on various uncertain factors, assigning different scenario deviation coefficients to the data of various uncertain factors to obtain updated data on uncertain factors and combining them to form different combined scenarios; using a genetic algorithm to calculate the values of the objective functions corresponding to each task under each combined scenario to obtain the optimal objective plan; and allocating carbon emissions based on a pre-constructed carbon emission flow model and the optimal objective plan.

[0005] For example, the pollution emission control method, device, and storage medium disclosed in the invention patent announcement with the announcement number CN112581107B include: obtaining the predicted air information of a region, where the predicted air information includes the type of air pollution; obtaining the 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 the target enterprises in the region, where the pollution emission type of the target enterprises corresponds to the type of air pollution.

[0006] However, in the process of implementing the technical solution of the invention in the embodiments of the present application, it is found that the above technology has at least the following technical problems: Industrial parks are an important source of nitrogen oxide and volatile organic compound emissions. The formation of ozone depends on the interaction between nitrogen oxides and volatile organic compounds, and the specific relationship is affected by many factors. Under fog and haze weather conditions, factors such as the chemical reaction rate, diffusion, and sedimentation of nitrogen oxides and volatile organic compounds are affected by meteorological conditions. For example, under the condition of poor air circulation, the accumulation of pollutants may exacerbate the formation of fog and haze, resulting in a lag in ozone pollution.

[0007] It should also be considered that under fog and haze weather, the meteorological conditions change greatly, and the impact of meteorological conditions on pollutants is very complex and variable. Factors such as temperature, wind speed, atmospheric stability, and solar radiation indirectly or directly affect the ambient air quality by changing the diffusion, reaction rate, and sedimentation process of pollutants (such as ozone). Under fog and haze weather conditions, these factors often lead to the accumulation of pollutants and further aggravation of pollution, and there is a problem that the emission allocation of nitrogen oxide emissions and volatile organic compound emissions in industrial parks under fog and haze weather is not sufficiently correlated with ozone pollution. Summary of the Invention

[0008] By providing an air pollution emission allocation method based on environmental quality improvement, the embodiments of the present application solve the problem in the prior art that the emission allocation of nitrogen oxide emissions and volatile organic compound emissions in industrial parks under fog and haze weather is not sufficiently correlated with ozone pollution, and effectively improve the rationality of the emission allocation of nitrogen oxide emissions and volatile organic compound emissions in industrial parks under fog and haze weather.

[0009] The embodiment of the present application provides an air pollution emission allocation method based on environmental quality improvement, including the following steps: obtaining an ozone emission pollution determination result based on the ozone emission concentration in the industrial park, and determining whether to perform ozone generation pollution emission allocation adjustment; if the ozone generation pollution emission allocation adjustment is performed, after performing the ozone emission allocation judgment update, obtaining the ozone precursor pollutant concentration data in the industrial park to evaluate the pollution risk degree of ozone generation under the interference of haze weather and sunlight, and combining the obtained ozone generation evaluation result to determine whether to perform precursor pollutant emission allocation optimization, where the precursor pollutant emission allocation optimization means combining the ozone generation evaluation result to allocate the nitrogen oxide emission and volatile organic compound emission to improve the impact of ozone generation pollution risk on environmental quality; if the ozone generation pollution emission allocation adjustment is not performed, after performing the ozone concentration deviation judgment, evaluating the pollution risk degree of ozone diffusion under the interference of haze weather and temperature inversion, and combining the obtained ozone diffusion evaluation result to determine whether to perform ozone diffusion emission allocation optimization, where the ozone diffusion emission allocation optimization means combining the ozone diffusion evaluation result to allocate the nitrogen oxide emission and volatile organic compound emission to improve the impact of ozone diffusion pollution risk on environmental quality.

[0010] Further, the specific process of determining whether to perform the ozone generation pollution emission allocation adjustment is as follows: obtaining the ozone emission threshold from the preset database, and comparing and judging the obtained ozone emission concentration with the ozone emission threshold; if the ozone emission concentration is not greater than the ozone emission threshold, recording the corresponding ozone emission pollution determination result as ozone emission qualified, performing the ozone generation pollution emission allocation adjustment, and continuously monitoring the ozone emission concentration; if the ozone emission concentration is greater than the ozone emission threshold, recording the corresponding ozone emission pollution determination result as ozone pollution emission exceeding the standard, not performing the ozone generation pollution emission allocation adjustment, and prompting to perform the ozone diffusion pollution emission allocation adjustment; the ozone generation pollution emission allocation adjustment means combining the ozone generation evaluation result to adjust the emission amount of ozone generation precursor pollutants to reduce the impact of ozone generation risk on environmental quality; the ozone diffusion pollution emission allocation adjustment means adjusting the emission of ozone generation precursor pollutants after evaluating the pollution risk of ozone diffusion to reduce the impact of ozone diffusion risk on environmental quality.

[0011] Further, the specific process of implementing ozone generation pollution emission allocation adjustment is as follows: After performing ozone emission allocation judgment update, obtain the ozone precursor pollutant concentration data in the industrial park. Ozone emission allocation judgment update means updating the ozone emission threshold to the ozone emission determination threshold according to the emission determination update threshold intensity. The ozone precursor pollutant concentration data includes meteorological pollution interference data and ozone precursor concentration data; The emission determination update threshold intensity represents the result of mapping the deviation degree between the ozone emission concentration and the ozone emission threshold into the emission determination threshold mapping set in the preset database. The emission determination threshold mapping set establishes the mapping relationship between the ozone emission concentration and the deviation degree of the ozone emission threshold and the emission determination update threshold intensity; Based on the ozone precursor pollutant concentration data, quantitatively evaluate the pollution risk degree of ozone generation under the interference of haze meteorological light, and obtain the ozone generation pollution risk value. The ozone generation pollution risk value is used to quantitatively evaluate the pollution risk degree of ozone generation under the interference of haze meteorological light; Compare the obtained ozone generation pollution risk value with the preset ozone generation pollution risk determination range obtained from the preset database to obtain the ozone generation evaluation result. The ozone generation evaluation result includes ozone generation pollution risk qualified and ozone generation pollution risk warning.

[0012] Further, the ozone generation pollution risk value is obtained through the following specific steps: Obtain the meteorological pollution interference data and ozone precursor concentration data within the preset generation pollution monitoring time period according to the initial monitoring collection frequency. The meteorological pollution interference data includes the ultraviolet radiation intensity, the concentration of haze particles, and the meteorological light intensity. The ozone precursor concentration data includes the concentration of nitrogen oxides and the concentration of volatile organic compounds. Weight and couple the relative deviation of the ultraviolet radiation intensity, the relative deviation of the haze particle concentration, and the relative deviation of the meteorological light intensity respectively through the interference compensation amounts obtained from the preset database to obtain the ozone generation meteorological interference factor. The interference compensation amounts include the meteorological ultraviolet interference compensation amount, the meteorological particle interference compensation amount, and the meteorological light intensity interference compensation amount. Perform pollution risk meteorological correction and interaction processing on the ozone generation risk weighted coupling result and the ozone generation meteorological interference factor to obtain the ozone generation pollution risk value. The ozone generation risk weighted coupling result represents the result of coupling the ratio results of the nitrogen oxide concentration and the volatile organic compound concentration with the corresponding risk compensation amounts after weighted calculation. The pollution risk meteorological correction and interaction processing is used to describe the interaction between the ozone generation risk weighted coupling result and the ozone generation meteorological interference factor. The risk compensation amounts include the nitrogen oxide risk compensation amount and the volatile organic compound risk compensation amount. The ratio result of the nitrogen oxide concentration represents the result of the ratio operation of the nitrogen oxide concentration and the reference maximum concentration of nitrogen oxides. The ratio result of the volatile organic compound concentration represents the result of the ratio operation of the volatile organic compound concentration and the reference maximum concentration of volatile organic compounds. The ozone generation pollution risk value represents the quantitative data for evaluating the pollution risk degree of ozone generation under the interference of haze meteorological light by the ozone generation meteorological interference factor, the nitrogen oxide concentration, and the volatile organic compound concentration.

[0013] Further, the ozone generation evaluation result is obtained through the following specific steps: If the obtained ozone generation pollution risk value is not within the preset ozone generation pollution risk determination range obtained from the preset database, then record the corresponding ozone generation evaluation result as ozone generation pollution risk qualified, do not perform the optimization of precursor pollutant emission allocation, and continuously judge 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, then record the corresponding ozone generation evaluation result as ozone generation pollution risk warning and perform the optimization of precursor pollutant emission allocation.

[0014] Further, the specific steps for implementing the optimization of precursor pollutant emission allocation are as follows: The ozone emission concentration, the deviation degree of the ozone generation pollution risk value from the reference ozone generation pollution risk threshold are jointly input into the nitrogen oxide allocation adjustment mapping set in the preset database for mapping to obtain the nitrogen oxide emission adjustment intensity. The initial set nitrogen oxide emissions of the pollution source are updated with the nitrogen oxide emission adjustment intensity to obtain the set nitrogen oxide emissions. If the nitrogen oxide emissions of the pollution source are greater than the obtained set nitrogen oxide emissions, a stop nitrogen oxide emission instruction is sent; otherwise, the nitrogen oxide emissions of the pollution source are continuously monitored. The set nitrogen oxide emissions are used to describe the maximum value of the nitrogen oxide emissions that the pollution source can emit after updating the initial set nitrogen oxide emissions of the pollution source with the nitrogen oxide emission adjustment intensity. The nitrogen oxide allocation adjustment mapping set establishes a mapping relationship between the ozone emission concentration and the deviation degree of the ozone generation pollution risk value jointly and the nitrogen oxide emission adjustment intensity. The ozone emission concentration, the deviation degree of the ozone generation pollution risk value from the reference ozone generation pollution risk threshold are jointly input 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 initial set volatile organic compound emissions of the pollution source are updated with the volatile organic compound emission adjustment intensity to obtain the set volatile organic compound emissions. If the volatile organic compound emissions of the pollution source are greater than the obtained set volatile organic compound emissions, a stop volatile organic compound emission instruction is sent; otherwise, the volatile organic compound emissions of the pollution source are continuously monitored. The set volatile organic compound emissions are used to describe the maximum value of the volatile organic compound emissions that the pollution source can emit after updating the initial set volatile organic compound emissions of the pollution source with the volatile organic compound emission adjustment intensity. The volatile organic compound allocation adjustment mapping set establishes a mapping relationship between the ozone emission concentration and the deviation degree of the ozone generation pollution risk value jointly and the volatile organic compound emission adjustment intensity. The ozone precursor pollutant concentration data is collected according to the adjusted sampling frequency to obtain the secondary ozone generation pollution risk value. If the secondary ozone generation pollution risk value is within the preset ozone generation pollution risk determination range, a precursor pollutant emission allocation optimization end prompt is sent; otherwise, an ozone emission concentration monitoring instruction is sent. The adjusted sampling frequency represents the result of inputting the ozone generation pollution risk value into the monitoring sampling mapping set in the preset database for mapping. The monitoring sampling mapping set establishes a mapping relationship between the ozone generation pollution risk value and the adjusted sampling frequency.

[0015] Further, the specific process for regulating the distribution of ozone diffusion pollution emissions is as follows: Determine whether the deviation degree 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 deviation degree between the ozone emission concentration and the ozone emission threshold is within the preset ozone pollution controllable range, obtain the ozone diffusion quantification data within the industrial park; otherwise, send an instruction to stop the emission of ozone precursor pollutants. Evaluate the pollution risk degree of ozone diffusion under the interference of haze meteorological inversion based on the ozone diffusion quantification data to obtain an ozone diffusion pollution risk value, which is used to quantitatively evaluate the pollution risk degree of ozone diffusion under the interference of haze meteorological inversion. Combine with the preset ozone diffusion pollution risk determination range obtained from the preset database to compare and judge the obtained ozone diffusion pollution risk value to obtain an ozone diffusion evaluation result, which includes normal ozone diffusion and ozone diffusion warning.

[0016] Further, to obtain the ozone diffusion pollution risk value, the specific steps are as follows: Obtain the ozone diffusion quantification data for the preset ozone diffusion monitoring time period within the industrial park, where the ozone diffusion quantification data includes the average inversion intensity, average meteorological wind speed, and ozone concentration. Perform a weighted coupling process on the relative deviation of the average inversion intensity and the relative deviation of the average meteorological wind speed with the diffusion interference compensation amount obtained from the preset database to obtain an ozone diffusion meteorological interference factor, and the diffusion interference compensation amount includes an inversion diffusion interference compensation amount and a meteorological wind speed diffusion interference compensation amount. Perform a diffusion risk meteorological correction interaction process on the cumulative effect operation result of the ozone concentration during the preset ozone diffusion monitoring time period and the ozone diffusion meteorological interference factor to obtain an ozone diffusion pollution risk value, and the diffusion risk meteorological correction interaction process is used to describe the interaction between the cumulative processing result of the ozone concentration and the ozone diffusion meteorological interference factor. The ozone diffusion pollution risk value represents the quantitative data for evaluating the pollution risk degree of ozone diffusion under the interference of haze meteorological inversion by the ozone diffusion meteorological interference factor and the ozone concentration.

[0017] Further, to obtain the ozone diffusion evaluation result, the specific steps are as follows: If the obtained ozone diffusion pollution risk value is not within the preset ozone diffusion pollution risk determination range obtained from the preset database, record the corresponding ozone diffusion evaluation result as normal ozone diffusion, do not perform the optimization of ozone diffusion emission distribution, and continuously determine whether the ozone diffusion pollution risk value is within the preset ozone diffusion pollution risk determination range; if the obtained ozone diffusion pollution risk value is within the preset ozone diffusion pollution risk determination range obtained from the preset database, record the corresponding ozone diffusion evaluation result as ozone diffusion warning and perform the optimization of ozone diffusion emission distribution.

[0018] Further, the specific steps for implementing the optimization of ozone diffusion emission allocation are as follows: The ozone emission concentration and the ozone diffusion pollution risk value are jointly input into the nitrogen oxide allocation optimization mapping set in the preset database for mapping to obtain the nitrogen oxide emission optimization intensity. The initial set nitrogen oxide emissions of the pollution source are updated with the nitrogen oxide emission optimization intensity to obtain the optimized nitrogen oxide emissions. If the nitrogen oxide emissions of the pollution source are greater than the obtained optimized nitrogen oxide emissions, a stop nitrogen oxide emission instruction is sent. Otherwise, the nitrogen oxide emissions of 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 in the next ozone diffusion monitoring time period. The nitrogen oxide allocation optimization mapping set establishes a mapping relationship between the deviation degree of the ozone emission concentration and the ozone diffusion pollution risk value and the nitrogen oxide emission optimization intensity. The optimized nitrogen oxide emissions are used to describe the maximum value of the nitrogen oxide emissions that the pollution source can emit nitrogen oxide after updating the initial set nitrogen oxide emissions of the pollution source with the nitrogen oxide emission optimization intensity. If the secondary ozone diffusion monitoring value is not within the preset ozone diffusion pollution risk determination range, the ozone diffusion pollution risk value is continuously monitored. Otherwise, a stop nitrogen oxide emission instruction is sent. The ozone emission concentration and the ozone diffusion pollution risk value are jointly input into the volatile organic compound allocation optimization mapping set in the preset database for mapping to obtain the volatile organic compound emission optimization intensity. The initial set volatile organic compound emissions of the pollution source are updated with the volatile organic compound emission optimization intensity to obtain the optimized volatile organic compound emissions. If the volatile organic compound emissions of the pollution source are greater than the obtained set volatile organic compound emissions, a stop volatile organic compound emission instruction is sent. Otherwise, the volatile organic compound emissions of the pollution source are continuously monitored and the secondary ozone diffusion monitoring value is obtained. The volatile organic compound allocation optimization mapping set establishes a mapping relationship between the deviation degree of the ozone emission concentration and the ozone diffusion pollution risk value and the volatile organic compound emission optimization intensity. The optimized volatile organic compound emissions are used to describe the maximum value of the volatile organic compound emissions that the pollution source can emit volatile organic compounds after updating the initial set volatile organic compound emissions of the pollution source with the volatile organic compound emission optimization intensity. If the secondary ozone diffusion monitoring value is not within the preset ozone diffusion pollution risk determination range, the ozone diffusion pollution risk value is continuously monitored. Otherwise, a stop volatile organic compound emission instruction is sent.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Embodiments of the present application provide an air pollution emission allocation method based on environmental quality improvement, which solves the problem in the prior art that the emission allocation of nitrogen oxides and volatile organic compounds in industrial parks under haze weather is not sufficiently correlated with ozone pollution. The ozone emission pollution determination result is obtained through the ozone emission concentration in the industrial park, and it is judged whether to perform the ozone generation pollution emission allocation adjustment. If the ozone generation pollution emission allocation adjustment is performed, after the ozone emission allocation judgment is updated, the ozone precursor pollutant concentration data in the industrial park is obtained to evaluate the pollution risk degree of ozone generation under the interference of haze weather light. Then, in combination with the obtained ozone generation evaluation result, it is judged whether to perform the precursor pollutant emission allocation optimization. If the ozone generation pollution emission allocation adjustment is not performed, after the ozone concentration deviation judgment, the pollution risk degree of ozone diffusion under the interference of haze weather inversion is evaluated. Then, in combination with the obtained ozone diffusion evaluation result, it is judged whether to perform the ozone diffusion emission allocation optimization, effectively improving the rationality of the emission allocation of nitrogen oxides and volatile organic compounds in industrial parks under haze weather.

[0024] The technical solution in the embodiments of the present application is to solve the problem that the emission allocation of nitrogen oxides and volatile organic compounds in industrial parks under haze weather is not sufficiently correlated with ozone pollution. The general idea is as follows: It is judged whether to perform the ozone generation pollution emission allocation adjustment through the ozone emission pollution determination result. If so, it is judged whether to perform the precursor pollutant emission allocation optimization in combination with the obtained ozone generation evaluation result. Otherwise, it is judged whether to perform the ozone diffusion emission allocation optimization in combination with the obtained ozone diffusion evaluation result, achieving the effect of improving the rationality of the emission allocation of nitrogen oxides and volatile organic compounds in industrial parks under haze weather.

[0025] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0026] As Figure 1As shown in the figure, it is a flowchart of the air pollution emission allocation method based on environmental quality improvement provided by the embodiment of the present application. The method includes the following steps: obtaining an ozone emission pollution determination result based on the ozone emission concentration in the industrial park, and determining whether to perform ozone generation pollution emission allocation adjustment; if performing ozone generation pollution emission allocation adjustment, after performing ozone emission allocation judgment update, obtaining the ozone precursor pollutant concentration data in the industrial park to evaluate the pollution risk degree of ozone generation under the interference of haze weather and sunlight, and combining the obtained ozone generation evaluation result to determine whether to perform precursor pollutant emission allocation optimization. Precursor pollutant emission allocation optimization means combining the ozone generation evaluation result to allocate the nitrogen oxide emission and volatile organic compound emission to improve the impact of ozone generation pollution risk on environmental quality; if not performing ozone generation pollution emission allocation adjustment, after performing ozone concentration deviation judgment, evaluating the pollution risk degree of ozone diffusion under the interference of haze weather inversion to obtain an ozone diffusion pollution risk value, and based on the ozone diffusion pollution risk value, obtaining an ozone diffusion evaluation result, and determining whether to perform ozone diffusion emission allocation optimization according to the ozone diffusion evaluation result. Ozone diffusion emission allocation optimization means combining the ozone diffusion evaluation result to allocate the nitrogen oxide emission and volatile organic compound emission to improve the impact of ozone diffusion pollution risk on environmental quality.

[0027] As Figure 2 As shown in the figure, it is a structural flowchart of the air pollution emission allocation method based on environmental quality improvement provided by the embodiment of the present application. The corresponding logic is: determining whether to perform ozone generation pollution emission allocation adjustment based on the ozone emission concentration. If performing ozone generation pollution emission allocation adjustment, evaluating the pollution risk degree of ozone generation under the interference of haze weather and sunlight to obtain an ozone generation pollution risk value, obtaining an ozone generation evaluation result based on the ozone generation pollution risk value, and determining whether to perform precursor pollutant emission allocation optimization according to the ozone generation evaluation result. If not performing ozone generation pollution emission allocation adjustment, evaluating the pollution risk degree of ozone diffusion under the interference of haze weather inversion to obtain an ozone diffusion pollution risk value, obtaining an ozone diffusion evaluation result based on the ozone diffusion pollution risk value, and determining whether to perform ozone diffusion emission allocation optimization according to the ozone diffusion evaluation result.

[0028] In this embodiment, with the acceleration of the industrialization process, especially in areas with dense industrial parks, pollutant emissions have become an important factor affecting air quality, environmental health, and the quality of public life. In addition, under haze weather conditions, the atmosphere is stable, the air flow is weak, and pollutants are difficult to disperse and dilute, resulting in the accumulation of pollutants near the ground, seriously affecting air quality and human health. Ozone pollution is a typical secondary pollution, which is produced by the chemical reaction of nitrogen oxides and volatile organic compounds in the atmosphere. In haze weather, due to poor atmospheric diffusion conditions, the concentrations of ozone and other pollutants may reach dangerous levels. Therefore, by analyzing the emissions of nitrogen oxides and volatile organic compounds in industrial parks and accurately allocating emissions, a theoretical basis can be provided for the control of ozone pollution. Taking measures to reduce the emissions of these pollutants helps to reduce ozone concentration and improve air quality. The existing pollutant emission monitoring technologies are not fully adapted to emission allocation and ozone pollution management under complex weather conditions. Researching and formulating reliable air pollution emission allocation methods is of great significance for improving the environmental quality monitoring ability under haze weather. The algorithm of this application analyzes the emission allocation of nitrogen oxides and volatile organic compounds in industrial parks under haze weather and their relationship with ozone pollution, so as to reasonably allocate the corresponding nitrogen oxide emissions and volatile organic compound emissions under different ozone pollution risk levels, which is of great significance for improving environmental quality. It can not only reduce ozone pollution, improve air quality, but also reduce public health risks and promote the development of green technologies.

[0029] Further, it is judged whether to execute the ozone generation pollution emission allocation adjustment, and the specific process is as follows: First, obtain the ozone emission threshold from the preset database, and compare and judge the obtained ozone emission concentration 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 as 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.

[0030] Second, if the ozone emission concentration is not greater than the ozone emission threshold, the corresponding ozone emission pollution determination result is recorded as ozone emission qualified, execute the ozone generation pollution emission allocation adjustment, and continuously monitor the ozone emission concentration.

[0031] It should be added that the specific process of executing the ozone generation pollution emission allocation adjustment is as follows: A1. After performing the update of ozone emission allocation judgment, obtain the concentration data of ozone precursor pollutants in the industrial park. Among them, the concentration data of ozone precursor pollutants includes meteorological pollution interference data and ozone precursor concentration data; the update of ozone emission allocation judgment means updating the ozone emission threshold to the ozone emission determination threshold according to the update threshold intensity of emission determination.

[0032] Specifically, the update threshold intensity of emission determination represents the result of mapping the deviation degree between the ozone emission concentration and the ozone emission threshold into the emission determination threshold mapping set in the preset database. The emission determination threshold mapping set establishes the mapping relationship between the ozone emission concentration, the deviation degree between the ozone emission threshold and the emission determination update threshold intensity; specifically, as the deviation degree between the ozone emission concentration and the ozone emission threshold increases, the update threshold intensity of emission determination increases accordingly. The deviation degree between the ozone emission concentration and the ozone emission threshold is the result of the difference operation between the ozone emission threshold and the ozone emission concentration.

[0033] A2. Quantitatively evaluate the pollution risk degree of ozone generation under the interference of haze meteorological light based on the concentration data of ozone precursor pollutants, and obtain the ozone generation pollution risk value. Among them, to obtain the ozone generation pollution risk value, the specific steps are as follows: A21. Obtain the meteorological pollution interference data and ozone precursor concentration data within the preset generation pollution monitoring time period according to the initial monitoring collection frequency. The meteorological pollution interference data includes ultraviolet radiation intensity, haze particle concentration, and meteorological light intensity. The ozone precursor concentration data includes nitrogen oxide concentration and volatile organic compound concentration; specifically, both the meteorological pollution interference data and the ozone precursor concentration data are processed to remove the unit. The meteorological pollution interference data is obtained through the air quality monitoring station. The corresponding ultraviolet radiation intensity reference value, haze particle reference concentration, and meteorological light intensity reference value are represented by the average result of the ultraviolet radiation intensity, haze particle concentration, and meteorological light intensity collected within the historical time period; the nitrogen oxide concentration and volatile organic compound concentration are obtained through the nitrogen oxide sensor and gas chromatograph deployed at the pollution source emission port. The corresponding nitrogen oxide reference maximum concentration and volatile organic compound reference maximum concentration are represented by the maximum value of the nitrogen oxide concentration and volatile organic compound concentration collected within the historical time period.

[0034] A22. Weight the relative deviation of ultraviolet radiation intensity (i.e., part of the ozone generation meteorological interference factor), the relative deviation of haze particle concentration (i.e., part of the ozone generation meteorological interference factor), and the relative deviation of meteorological light intensity (i.e., part of the ozone generation meteorological interference factor) respectively through the interference compensation amount obtained from the preset database, and then couple them to obtain the ozone generation meteorological interference factor; the numerical expression of the ozone generation meteorological interference factor is as follows: Part), the relative deviation of haze particle concentration (i.e., part of the ozone generation meteorological interference factor), and Part) and the relative deviation of meteorological light intensity (i.e., part of the ozone generation meteorological interference factor) are respectively weighted and calculated through the interference compensation amount obtained from the preset database and then coupled to obtain the ozone generation meteorological interference factor; the numerical expression of the ozone generation meteorological interference factor is as follows: Part) are respectively weighted and calculated through the interference compensation amount obtained from the preset database and then coupled to obtain the ozone generation meteorological interference factor; the numerical expression of the ozone generation meteorological interference factor is as follows: ; In the formula, represents the ozone generation meteorological interference factor during the preset pollution monitoring time period, represents the meteorological ultraviolet interference compensation amount, represents the meteorological particle interference compensation amount, represents the meteorological light intensity interference compensation amount, represents the ultraviolet radiation intensity during the preset pollution monitoring time period, represents the reference value of the ultraviolet radiation intensity, represents the concentration of haze particles during the preset pollution monitoring time period, represents the reference concentration of haze particles, represents the meteorological light intensity during the preset pollution monitoring time period, represents the reference value of the meteorological light intensity.

[0035] Among them, the interference compensation amount includes the meteorological ultraviolet interference compensation amount, the meteorological particle interference compensation amount, and the meteorological light intensity interference compensation amount. The meteorological ultraviolet interference compensation amount, the meteorological particle interference compensation amount, and the meteorological light intensity interference compensation amount are respectively used to describe the influence degrees of the relative deviation of the ultraviolet radiation intensity, the relative deviation of the haze particle concentration, and the relative deviation of the meteorological light intensity on the ozone generation meteorological interference factor. The sum of the three is 1. By inputting the real-time relative deviation of the ultraviolet radiation intensity, the relative deviation of the haze particle concentration, and the relative deviation of the meteorological light intensity into the mapping set of the relative deviation of the ultraviolet radiation intensity, the relative deviation of the haze particle concentration, and the relative deviation of the meteorological light intensity and their corresponding compensation amounts preset in the database, the corresponding meteorological ultraviolet interference compensation amount, meteorological particle interference compensation amount, and meteorological light intensity interference compensation amount are obtained.

[0036] A23, perform pollution risk meteorological correction interaction processing on the ozone generation risk weighted coupling result (i.e., the part in the ozone generation pollution risk value) and the ozone generation meteorological interference factor to obtain the ozone generation pollution risk value. The ozone generation risk weighted coupling result represents the result of the weighted operation and coupling of the nitrogen oxide concentration ratio result and the volatile organic compound concentration ratio result with the corresponding risk compensation amounts. The nitrogen oxide concentration ratio result represents the result of the ratio operation of the nitrogen oxide concentration to the reference maximum concentration of nitrogen oxides. The volatile organic compound concentration ratio result represents the result of the ratio operation of the volatile organic compound concentration to the reference maximum concentration of volatile organic compounds. The pollution risk meteorological correction interaction processing is used to describe the interaction between the ozone generation risk weighted coupling result and the ozone generation meteorological interference factor, that is, the process of obtaining the numerical expression of the ozone generation pollution risk value. The numerical expression of the ozone generation pollution risk value is as follows: ; In the formula, represents the ozone generation pollution risk value within the preset generation pollution monitoring time period, represents the nitrogen oxide risk compensation amount, represents the volatile organic compound risk compensation amount, represents the nitrogen oxide concentration within the preset generation pollution monitoring time period, represents the reference maximum concentration of nitrogen oxides, represents the volatile organic compound concentration within the preset generation pollution monitoring time period, represents the reference maximum concentration of volatile organic compounds.

[0037] 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 their value ranges are both from 0 to 1. By inputting the real-time nitrogen oxide concentration ratio result and the volatile organic compound concentration ratio result into the mapping set of the nitrogen oxide concentration ratio result and the volatile organic compound concentration ratio result preset in the database and their respectively corresponding compensation amounts, the corresponding nitrogen oxide risk compensation amount and volatile organic compound risk compensation amount are obtained.

[0038] It should be understood that the ozone generation pollution risk value is used to quantitatively evaluate the pollution risk degree of ozone generation under the interference of haze meteorological light. Among them, the ozone generation meteorological interference factor, nitrogen oxide concentration, and volatile organic compound concentration in the ozone generation pollution risk value together represent the quantitative data for evaluating the pollution risk degree of ozone generation under the interference of haze meteorological light; the ozone generation pollution risk value contains multiple parameters, and there is a correlation between the various parameters. The correlation and mutual influence between the various parameters are considered in a quantitative way. For example, the ultraviolet radiation intensity has a direct impact on ozone generation because ultraviolet light can promote the chemical reaction of nitrogen oxides and volatile organic compounds, thereby generating ozone. Usually, when the ultraviolet radiation intensity increases, the reaction of ozone generation will be promoted. When the ultraviolet radiation and light intensity are strong, that is, when the ozone generation meteorological interference factor increases, the higher the concentration of nitrogen oxides, the greater the possibility and speed of ozone generation, making the ozone generation pollution risk value increase accordingly. At the same time, the concentration of haze particles usually affects the propagation of ultraviolet radiation, and thus affects the degree of ozone generation. The increase in haze concentration will reduce the amount of ultraviolet radiation reaching the ground, increase the ozone generation meteorological interference factor, thereby affecting the ozone generation reaction. At the same time, the haze particles themselves may also participate in the ozone generation reaction, further enhancing the generation of ozone. The light intensity is closely related to the ultraviolet radiation. The increase in light intensity usually means an increase in ultraviolet radiation, thereby promoting the reaction of nitrogen oxides and volatile organic compounds to generate ozone.

[0039] A3. Compare the obtained ozone generation pollution risk value with the preset ozone generation pollution risk determination range retrieved from the preset database to obtain the ozone generation assessment result. The ozone generation assessment result includes that the ozone generation pollution risk is qualified and the ozone generation pollution risk is on alert. The preset ozone generation pollution risk determination range is set by professionals according to the standards in the field.

[0040] Among them, to obtain the ozone generation assessment result, the specific steps are as follows: A31. If the obtained ozone generation pollution risk value is not within the preset ozone generation pollution risk determination range retrieved from the preset database, record the corresponding ozone generation assessment result as the ozone generation pollution risk being qualified, do not perform the optimization of precursor pollutant emission allocation, and continuously determine whether the ozone generation pollution risk value is within the preset ozone generation pollution risk determination range.

[0041] A32. If the obtained ozone generation pollution risk value is within the preset ozone generation pollution risk determination range retrieved from the preset database, record the corresponding ozone generation assessment result as the ozone generation pollution risk being on alert, and perform the optimization of precursor pollutant emission allocation.

[0042] Specifically, the specific steps for performing the optimization of precursor pollutant emission allocation are as follows: A321. Input the ozone emission concentration, the deviation degree of the ozone generation pollution risk value from the reference ozone generation pollution risk threshold into the nitrogen oxide allocation adjustment mapping set in the preset database for mapping to obtain the nitrogen oxide emission adjustment intensity. Among them, the reference ozone generation pollution risk value is the average result of the ozone generation pollution risk values collected during the historical time period, and the deviation degree of the ozone generation pollution risk value from the reference ozone generation pollution risk threshold is the absolute value of the difference operation between the ozone generation pollution risk value and the reference ozone generation pollution risk threshold. Update the initial set nitrogen oxide emissions of the pollution source with the nitrogen oxide emission adjustment intensity to obtain the nitrogen oxide set emissions.

[0043] If the nitrogen oxide emissions of the pollution source are greater than the obtained nitrogen oxide set emissions, send a stop nitrogen oxide emission instruction; otherwise, continuously monitor the nitrogen oxide emissions of the pollution source. The nitrogen oxide set emissions are used to describe the maximum nitrogen oxide emissions that the pollution source can emit after updating the initial set nitrogen oxide emissions of the pollution source with the nitrogen oxide emission adjustment intensity. The nitrogen oxide allocation adjustment mapping set establishes a mapping relationship between the ozone emission concentration and the deviation degree of the ozone generation pollution risk value and the nitrogen oxide emission adjustment intensity. As the ozone emission concentration and the deviation degree of the ozone generation pollution risk value increase, the nitrogen oxide emission adjustment intensity increases accordingly.

Input the ozone emission concentration, the ozone generation pollution risk value, and the deviation degree from the reference ozone generation pollution risk threshold into the volatile organic compound (VOC) allocation adjustment mapping set in the preset database for mapping to obtain the VOC emission adjustment intensity. Update the initial set VOC emissions of the pollution source with the VOC emission adjustment intensity to obtain the set VOC emissions. If the VOC emissions of the pollution source are greater than the obtained set VOC emissions, send a stop VOC emission instruction. Otherwise, continuously monitor the VOC emissions of the pollution source. The set VOC emissions are used to describe the maximum value of the VOC emissions that the pollution source can emit after updating the initial set VOC emissions of the pollution source with the VOC emission adjustment intensity. The VOC allocation adjustment mapping set establishes a mapping relationship between the ozone emission concentration and the deviation degree of the ozone generation pollution risk value and the VOC emission adjustment intensity. As the ozone emission concentration and the deviation degree of the ozone generation pollution risk value increase, the VOC emission adjustment intensity increases accordingly.

[0045] A323. Collect the ozone precursor pollutant concentration data according to the adjusted collection frequency, obtain the secondary ozone generation pollution risk value, and compare and judge the secondary ozone generation pollution risk value in combination with the preset ozone generation pollution risk determination range. If the secondary ozone generation pollution risk value is within the preset ozone generation pollution risk determination range, send a prompt for the end of the precursor pollutant emission allocation optimization. Otherwise, send an ozone emission concentration monitoring instruction. The adjusted 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 adjusted collection frequency. As the ozone generation pollution risk value increases, the adjusted collection frequency increases accordingly.

[0046] In addition, if the ozone emission concentration is greater than the ozone emission threshold, record the corresponding ozone emission pollution determination result as ozone pollution emission exceeding the standard, do not perform the ozone generation pollution emission allocation adjustment, and prompt for the ozone diffusion pollution emission allocation adjustment.

[0047] Specifically, the specific process of the ozone diffusion pollution emission allocation adjustment is as follows: B1. Judge whether the deviation degree 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 deviation degree between the ozone emission concentration and the ozone emission threshold is within the preset ozone pollution controllable range, obtain the ozone diffusion quantification data in the industrial park. Otherwise, send a stop ozone precursor pollutant emission instruction. The preset ozone pollution controllable range is set by professionals according to the standards in the field.

[0048] B2. Evaluate the pollution risk degree of ozone diffusion under the interference of haze meteorological inversion based on the quantified ozone diffusion data to obtain the ozone diffusion pollution risk value. Among them, to obtain the ozone diffusion pollution risk value, the specific steps are as follows: B21. Obtain the ozone diffusion quantified data for the preset ozone diffusion monitoring time period in the industrial park. The ozone diffusion quantified data includes the average inversion intensity, the average meteorological wind speed, and the ozone concentration. Specifically, the ozone diffusion quantified data has been de - unitized. The average inversion intensity and the average meteorological wind speed are obtained through a meteorological observation station, and the ozone concentration is obtained through a ground ozone monitoring station.

[0049] B22. Perform weighted coupling processing on the relative deviation of the average inversion intensity (i.e., the part in the ozone diffusion meteorological interference factor) and the relative deviation of the average meteorological wind speed (i.e., the part in the ozone diffusion meteorological interference factor) with the diffusion interference compensation amount obtained from the preset database to obtain the ozone diffusion meteorological interference factor. The numerical expression of the ozone diffusion meteorological interference factor is as follows: ; In the formula, represents the ozone diffusion meteorological interference factor for the preset ozone diffusion monitoring time period, represents the inversion diffusion interference compensation amount, represents the meteorological wind speed diffusion interference compensation amount, represents the average inversion intensity for the preset ozone diffusion monitoring time period, represents the reference value of the inversion intensity, represents the average meteorological wind speed for the preset ozone diffusion monitoring time period, represents the reference value of the meteorological wind speed.

[0050] The diffusion interference compensation amount includes the inversion diffusion interference compensation amount and the meteorological wind speed diffusion interference compensation amount. The value ranges of both are from 0 to 1 and their sum is 1, which are respectively used to describe the influence degree of the relative deviation of the average inversion intensity and the relative deviation of the average meteorological wind speed on the ozone diffusion meteorological interference factor. The corresponding inversion diffusion interference compensation amount and meteorological wind speed diffusion interference compensation amount are obtained by inputting the real - time relative deviation of the average inversion intensity and the relative deviation of the average meteorological wind speed into the mapping set of the relative deviation of the average inversion intensity and the relative deviation of the average meteorological wind speed and their respectively corresponding compensation amounts preset in the database.

[0051] B23. Perform cumulative effect operation processing on the ozone concentration for the preset ozone diffusion monitoring time period and then perform diffusion risk meteorological correction interaction processing with the ozone diffusion meteorological interference factor to obtain the ozone diffusion pollution risk value. The diffusion risk meteorological correction interaction processing is used to describe the result of the ozone concentration cumulative processing (i.e., the The interaction between the (part) and the ozone diffusion meteorological interference factor, that 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: ; In the formula, represents the ozone diffusion pollution risk value for the preset ozone diffusion monitoring time period, represents any moment in the preset ozone diffusion monitoring time period, , represents the time window length of the preset ozone diffusion monitoring time period, , represents the end moment of the preset ozone diffusion monitoring time period, represents the ozone concentration at time t within the preset ozone diffusion monitoring time period.

[0052] It should be understood that the ozone diffusion pollution risk value represents the quantitative data for evaluating the pollution risk degree of ozone diffusion under the interference of haze meteorological inversion by the ozone diffusion meteorological interference factor and the ozone concentration, and is used to quantitatively evaluate the pollution risk degree of ozone diffusion under the interference of haze meteorological inversion. Among them, the ozone diffusion pollution risk value, through a quantitative method, considers the correlation and mutual influence relationship between various parameters. Specifically, for example, inversion will lead to an increase in the stability of the atmosphere, limit the vertical diffusion of ozone, and the ozone diffusion meteorological interference factor will increase accordingly, thereby causing the ozone concentration to rise, especially in severe haze weather; the average inversion intensity directly affects ozone diffusion. Inversion will inhibit the vertical diffusion of ozone, resulting in the accumulation of ozone at low altitudes and increasing the pollution risk. A strong inversion effect will cause the ozone concentration to increase, making the cumulative processing result of the ozone concentration increase accordingly, and then leading to an increase in the ozone diffusion pollution risk value; in addition, wind speed affects the horizontal diffusion of ozone. A lower wind speed will cause ozone to stay in a local area, the ozone diffusion meteorological interference factor will increase, causing the ozone concentration to increase accordingly, increasing the ozone diffusion pollution risk, and thus making the cumulative processing result of the ozone concentration increase accordingly, and then leading to an increase in the ozone diffusion pollution risk value as well.

The corresponding logic is as follows: The ozone diffusion evaluation result is obtained by judging the ozone diffusion pollution risk value through a preset ozone diffusion pollution risk determination range. The ozone diffusion evaluation 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 determination range, the ozone diffusion evaluation result is normal ozone diffusion, and the ozone diffusion emission allocation optimization is not executed, and it continues to judge whether the ozone diffusion pollution risk value is within the preset ozone diffusion pollution risk determination range. When the ozone diffusion pollution risk value is within the preset ozone diffusion pollution risk determination range obtained from the preset database, the ozone diffusion evaluation result is ozone diffusion warning, and the ozone diffusion emission allocation optimization is executed. The ozone diffusion pollution emission allocation adjustment reduces the impact of ozone diffusion risk on environmental quality by adjusting the emissions of ozone precursor pollutants.

[0055] Specifically, to obtain the ozone diffusion evaluation result, the specific steps are as follows: 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, then record the corresponding ozone diffusion evaluation result as normal ozone diffusion, do not execute the ozone diffusion emission allocation optimization, and continue to judge whether the ozone diffusion pollution risk value is within the preset ozone diffusion pollution risk determination range.

The secondary ozone diffusion monitoring value represents the ozone diffusion pollution risk value for the next ozone diffusion monitoring time period, and the optimized nitrogen oxide emissions are used to describe the maximum nitrogen oxide emissions that the pollution source can emit after updating the initial set nitrogen oxide emissions of the pollution source 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.

[0059] B322, determine whether the secondary ozone diffusion monitoring value is within the preset ozone diffusion pollution risk determination range. If the secondary ozone diffusion monitoring value is not within the preset ozone diffusion pollution risk determination range, continuously monitor the ozone diffusion pollution risk value; otherwise, send a stop nitrogen oxide emissions instruction.

[0061] If the volatile organic compound emissions of the pollution source are greater than the obtained volatile organic compound set emissions, send a stop volatile organic compound emissions instruction; otherwise, continuously monitor the volatile organic compound emissions of the pollution source and obtain the secondary ozone diffusion monitoring value. 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 optimized volatile organic compound emissions are used to describe the maximum volatile organic compound emissions that the pollution source can emit after updating the initial set volatile organic compound emissions of the pollution source with the volatile organic compound emission optimization intensity.

[0062] B324, determine whether the secondary ozone diffusion monitoring value is within the preset ozone diffusion pollution risk determination range. If the secondary ozone diffusion monitoring value is not within the preset ozone diffusion pollution risk determination range, continuously monitor the ozone diffusion pollution risk value; otherwise, send a stop volatile organic compound emissions instruction, and the stop volatile organic compound emissions instruction is used to stop the emission of volatile organic compounds from the pollution source.
