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.

Abstract

The invention provides an ozone leading precursor recognition method and device based on emission data. The method comprises the steps of acquiring meteorological field data of a target area in a preset time period and emission data of an ozone precursor; determining a plurality of precursor discharge combination scenes according to the meteorological field data and the discharge data of the ozoneprecursor; and identifying precursor pollutants which play a leading role in ozone generation according to the plurality of precursor emission combination scenes. According to meteorological field data and ozone precursor emission data, ozone generation is simulated through an atmospheric chemical box mode, chemical reactions are considered more comprehensively, the calculation speed is high, andcalculation resources are saved. Precursor pollutants playing a leading role can be rapidly identified. The relations between ozone and precursors of ozone are visually reflected by drawing an ozoneisoconcentration curve, the change condition of ozone concentration under the condition that precursors of different proportions are discharged and reduced is simulated, and powerful support is provided for ozone control decision making.

Description

technical field [0001] The application belongs to the technical field of environmental protection, and in particular relates to a method and device for identifying dominant ozone precursors based on emission data. 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 model simulation m...
