Ozone leading precursor recognition method and device, electronic equipment and storage medium

Abstract

The invention provides an ozone dominant precursor recognition method and device, electronic equipment and a storage medium. The method comprises the steps: acquiring meteorological field data and pollutant concentration simulation data of a target area in a preset time period; determining a plurality of precursor concentration combination scenes according to the meteorological field data and thepollutant concentration simulation data; and according to the multiple precursor concentration combination scenes, identifying precursor pollutants which play a leading role in ozone generation in thetarget area within a preset time period. Ozone generation is simulated through an atmospheric chemical box mode, chemical reactions are considered more comprehensively, the calculation speed is high,calculation resources are saved, and precursor pollutants playing a leading role are rapidly recognized. An ozone isoconcentration curve is drawn to visually reflect the relationship between ozone and precursors thereof, the change condition of ozone concentration under the condition that the concentrations of the precursors in different proportions are reduced is simulated, and a powerful support is provided for ozone pollution control decisions.

Description

technical field [0001] The application belongs to the technical field of environmental protection, and in particular relates to a method, device, electronic equipment and storage medium for identifying a dominant precursor of ozone. Background technique [0002] In recent years, atmospheric ozone pollution has been increasing and has become one of the important pollutants that plague urban air quality management. Tropospheric ozone is a secondary pollutant generated by a series of complex reactions triggered by the photolysis of nitrogen oxides. The main components involved in the ozone photochemical reaction process include volatile organic compounds (Volatile Organic Compounds, VOCs) and nitrogen oxides (Nitrogen Oxides, NO x ) and other ozone precursors. To solve the problem of urban ozone pollution, it is first necessary to identify the ozone precursors that play a leading role in the formation of ozone in the city. [0003] At present, in the related art, a numerical...

Problems solved by technology

[0004] However, the above-mentioned related technologies need to calculate the dynamic changes of the pollutant concentration on each grid point in the space, which requires a large amount of calculation, and usually requires the support of more high-performance computing resources

The difficulty of obtaining a high-quality gridded emission inventory also seriously affects the application effect of the above-mentioned related technologies.
