Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, under the condition that the receptor component spectrum is known and the source spectrum is unknown, the receptor model PMF combines the identification components and the operation results of all pollution sources to deduce the types of the pollution sources and the contribution of the pollution sources to the receptor. The pollution source class is generally classified into a primary source class (e.g., mobile source, stationary combustion source, biomass combustion source, industrial source, dust source) and a secondary source class.
However, the secondary source is generated by secondary conversion, and is not a source class directly discharged at a time, and thus cannot be applied to actual management and control, that is, each pollution source cannot be actually managed and controlled according to the condition of the secondary source class. In addition, as proved by research of the inventor, for the primary source class, more detailed source analysis is generally included, for example, the fixed combustion source can be divided into power generation, civil combustion and the like, but the PMF model cannot realize further analysis of the primary source class. Therefore, at present, the refined sources of the pollution emissions cannot be analyzed, and further, the industry emission reduction measures cannot be directly guided.
The pollution source list is established by methods such as statistical analysis and the like based on investigation of pollution conditions in a certain period of a certain region, and is the basis of analysis of pollution information such as regional pollution sources and pollution source emission. According to industry standards, sources of atmospheric pollution can be classified into the following ten categories: stationary combustion sources, process sources, mobile sources, solvent use sources, agricultural sources, fugitive dust sources, biomass combustion sources, storage and transportation sources, waste disposal sources, other emission sources. Each kind of source can be classified into different industry categories, for example, the dust source can be classified into construction dust, soil dust and the like. The discharged pollutants can be divided into the following nine types: SO2, NOx, CO, VOCs, NH3, PM10, PM2.5, BC (black carbon), OC (organic carbon). However, this method cannot solve the problem of mutual transformation between the primary pollution source and the secondary pollution source, and is not consistent with the actual pollution situation.
Based on this, according to the pollutant source analysis method and device provided by the embodiment of the invention, a secondary source type, a primary source type and pollution source contribution systems of various industry types are established by combining the receptor model and the pollution source list, so that the source analysis result output by the receptor model can guide industry emission reduction measures.
To facilitate understanding of the present embodiment, a method for analyzing a pollutant source disclosed in the present embodiment will be described in detail first.
Fig. 1 is a flowchart of a method for analyzing a pollutant source according to an embodiment of the present invention.
Referring to fig. 1, the method for analyzing a pollutant source includes the following steps:
step S102, determining the discharge amount of pollutants in a preset time range of each industry type based on the data of a pollution source list, wherein the discharge amount of the pollutants comprises the discharge amount of primary pollutants and the discharge amount of precursor of secondary pollutants; the data of the pollution source list is obtained based on a pollution source list established by methods such as statistical analysis and the like based on investigation of pollution conditions in a certain period of a certain area.
Step S104, determining the contribution proportion of the primary pollutants in each industry category to the pollutants according to the emission amount of the primary pollutants and a predetermined primary pollution source analysis result, wherein the primary pollution source analysis result comprises the contribution proportion of each pollution source to the pollutants, and the primary pollution source analysis result is determined based on a receptor model; each pollution source includes multiple industry categories, such as the stationary combustion sources in fig. 2 including industry categories of mining and manufacturing, power production, gas production and supply, and so on.
Step S106, determining the contribution ratio of secondary pollution species to the pollutants in each industry category according to the emission amount of the precursor of the secondary pollutants and a predetermined secondary pollution source analysis result, wherein the secondary pollution source analysis result comprises the contribution ratio of the secondary pollution source to the pollutants and the concentrations of multiple secondary pollution species, and the secondary pollution source analysis result is determined based on the receptor model;
step S108, determining the contribution ratio of each industry class to the pollutants according to the contribution ratio of the primary pollutants to the pollutants and the contribution ratio of the secondary pollutants to the pollutants in each industry class.
In a preferred embodiment of practical application, various pollutant discharge amounts corresponding to each industry category are obtained through pollution source list data, the contribution proportion of each pollution source to primary pollutants and secondary pollutants determined by combining a receptor model is further known, the contribution proportion of each industry category to the primary pollutants and the secondary pollutants can be further known, the secondary sources are refined into the primary sources, the primary sources are subdivided into the industry categories according to the list, and accordingly refined source analysis is achieved.
In an optional embodiment, the pollution source list data includes a time distribution coefficient corresponding to each industry category of the plurality of pollution sources and a total amount of emission of the plurality of pollutants corresponding to each industry category of the plurality of pollution sources, and step S102 further includes:
and determining the discharge amount of pollutants in the preset time range of each industry class based on the time distribution coefficient corresponding to each industry class in the multiple pollution sources and the total discharge amount of the multiple pollutants corresponding to each industry class in the multiple pollution sources.
As an alternative embodiment, the time allocation for the desired contaminant and the source of the contaminant may be based on a time allocation factor in the inventory data for the source of the contaminant.
For example, for a source class such as a fixed combustion source, the time distribution coefficient is distributed to a month according to the coal consumption and the like, or is directly and evenly distributed according to the month, for example, the total emission of PM2.5 in the whole year of mining industry and manufacturing industry is 1577.6485t, the emission in the research period is 1577.6485/12 x 3-394.4121 t when the research month is 11 months to 1 month of the next year; or for the source classes such as agricultural sources and the like, distribution coefficients of each month are different, the total amount is multiplied by the coefficient of the corresponding month for final addition to obtain the emission, for example, the emission coefficient of nitrogen fertilizer application for 11 months is 0.061, the emission coefficient of 12 months is 0.051, the emission coefficient of 1 month is 0.047, the total emission of NH3 in the whole year including the research period is 9629.2993t, the emission amount of the research period is 9629.2993 (0.061+0.051+0.047) is 1531.059t, and the emission amount after distribution of each industry class is shown in FIG. 2.
As an alternative embodiment, the primary pollutants comprise atmospheric particulate matter PM2.5/PM10 and the secondary pollutant precursors comprise ammonia NH3Sulfur dioxide SO2And nitrogen oxide NOx。
In an optional embodiment, step S104 further includes the following steps:
step 1.1), determining the contribution ratio of each industry category in each primary pollution source to the primary pollutants according to the discharge amount in the primary pollution source;
according to the discharge data of the primary pollutants after time distribution, the contribution proportion of each industry category in each primary pollution source to the primary pollutants can be calculated; as can be seen, in fig. 2, the total emission of PM2.5 whose pollution source is a fixed combustion source is 1565.9886t which is the sum of the emission of PM2.5 of each industry category of mining and manufacturing industry, power production, gas production and supply industry, thermal production and supply and civil combustion, the emission of PM2.5 whose industry category is mining and manufacturing industry is 394.1621t, and according to the ratio of the emission of PM2.5 of the industry to the total emission of PM2.5 of the fixed combustion source, it is further known that the contribution ratio of PM2.5 of the industry category is 25.17%, as shown in fig. 4;
in this embodiment, PM2.5 is taken as an example for explanation, and in other alternative embodiments, the method for treating other pollutants is the same as PM 2.5.
Step 1.2), determining the contribution ratio of each primary pollution source to the pollutants according to the primary pollution source analysis result output by the receptor model, such as the contribution ratio of a mobile source to PM2.5 in fig. 6 is 21.79%, the contribution ratio of a raise dust source to PM2.5 is 8.38%, the contribution ratio of a fixed combustion source to PM2.5 is 18.77%, and so on;
and 1.3) determining the contribution ratio of the primary pollutant in each industry class to the pollutant according to the contribution ratio of each industry class to the primary pollutant in each primary pollution source and the contribution ratio of each primary pollution source to the pollutant.
As an optional embodiment, the contribution ratio of the primary pollutant to the pollutant in each industry category in each primary pollution source is multiplied by the contribution ratio of each pollution source to the pollutant in the PMF source analysis result, so as to obtain the contribution ratio of the primary pollutant to the pollutant in each industry category, that is, the contribution ratio of each industry after the primary pollution source is refined, as shown in fig. 6, the contribution ratio of the road moving source to the pollutant in the moving source is 8.736%, the contribution ratio of the non-road moving source to the pollutant in the moving source is 2.0625%, and so on.
