Abstract

The invention relates to the field of pollutant prevention and control, and discloses a dynamic distribution simulation method and simulation system for pollutants in a to-be-detected area, and the simulation method comprises the steps: obtaining the actual measurement concentration data of the pollutants of a plurality of preset monitoring points in the to-be-detected area; acquiring the reference source intensity of each emission source in the to-be-detected area, and performing preliminary analogue simulation on the pollutant distribution condition according to the reference source intensity to obtain simulated concentration data; calculating the corrected source intensity of each emission source in the to-be-measured area according to the actually measured concentration data and the simulated concentration data; and according to the corrected source intensity, carrying out analogue simulation on the distribution condition of the pollutants in the to-be-detected area again to obtain the dynamic distribution condition of the pollutants in the to-be-detected area. Based on the technical scheme, according to the pre-constructed pollutant diffusion model and the actually measured pollutant concentration in the to-be-measured area, the corrected source intensity is calculated and fed back to the pollutant diffusion model, simulation is carried out again, and a more accurate pollutant dynamic distribution condition in the to-be-measured area can be obtained.

Description

technical field [0001] The invention relates to the field of pollutant prevention and control, in particular to a simulation method and a simulation system for the dynamic distribution of pollutants in an area to be measured. Background technique [0002] With the rapid development of industrial construction and urbanization and the rapid consumption of resources and energy, the atmospheric environment will face unprecedented pressure. Therefore, it is necessary to simulate and evaluate the emission of atmospheric pollutants in order to take targeted management and reduction measures row measures. [0003] In the existing technology, the simulation of air pollutant emissions is mostly simulated by simulation software using multi-source simulation methods. However, the analysis and evaluation methods of related technologies in the simulation calculation process are too simple, and it is difficult to effectively predict and evaluate pollutants. In the process of diffusion, ef...
