A Regional Ozone Pollution Traceability System Based on Lagrangian Trajectory Model and Chemical Box Model

Abstract

The invention belongs to the technical field of environmental monitoring and relates to an air pollution traceability system. The system of the present invention includes: an emission source input module for inputting emission data; an initialization module for setting the initial concentration of pollutants; an atmospheric chemistry module for simulating the chemical process during air mass movement according to the input emission data; atmospheric physics Module, which inputs meteorological parameters and simulates the physical process of air mass movement based on this; the result output module, which is used to output the concentration of pollutants and the rate of atmospheric chemical reaction process, quantify regional transmission and local generation to the target area O 3 Concentration contributions to quantify the contribution of different chemical processes to the target region O 3 concentration contribution. The system of the present invention comprehensively considers the physical and chemical processes of the atmosphere, reduces the evolution of the pollutant concentration and chemical reaction rate on the time-space scale during the movement of the air mass, accurately locates the emission area that causes ozone pollution in the target area, and optimizes the control of precursors and emissions. Department to provide scientific support for formulating control measures for ozone pollution in target areas.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring and relates to an air pollution traceability system. Background technique [0002] In recent years, due to rapid urbanization and industrialization, near-surface O 3 The pollution problem is getting worse. According to the air quality monitoring results released by the Ministry of Ecology and Environment of the People's Republic of China, since 2013, key pollutants included in routine monitoring such as SO 2 , NO 2 , CO, PM 2.5 , PM 10 The pollution situation has been continuously and significantly improved, except for O 3 The concentration is in a state of "not falling but increasing", which has become a major problem in winning the battle to defend the blue sky. o 3 What makes pollution prevention and control so challenging is that it is difficult to pinpoint the cause of O 3 The source of pollution is embodied in two key scientific issues: first, O 3 Atmospheric life i...
