Industrial park atmospheric pollutant diffusion simulating and tracing method

Abstract

The invention provides an industrial park atmospheric pollutant diffusion simulating and tracing method. The industrial park atmospheric pollutant diffusion simulating and tracing method specificallycomprises the following steps: (1) based on multi-point pollutant component analysis and concentration real-time monitoring data, analyzing atmospheric pollutant emission characteristics of an emission source, and calculating dynamic emission source intensity; (2) constructing an atmospheric pollutant diffusion model based on a Gaussian smoke plume diffusion theory and a smoke mass diffusion theory, calculating pollutant diffusion distribution characteristics of an emission source according to real-time meteorological data, and predicting the pollutant concentration of sensitive points; and (3) simulating and calculating the influence of the low-rise building within the factory boundary distance of the industrial park on airflow movement, determining a transmission path of emission sourcepollutants, and performing tracing analysis on sensitive point pollutants. The theories of Gaussian diffusion, smoke mass diffusion and computational fluid mechanics are integrated, the problem that the industrial park atmospheric pollutant emission traceability is difficult is solved, and the effective supervision of the industrial park ambient air quality is realized.
