Embodiment Construction
[0016] The present invention will be described in further detail below in combination with specific embodiments.
[0017] Concrete prediction steps of the present invention are:
[0018] a. Using the diffusion of continuous point sources in the Gaussian diffusion model, set the chimneys, discharge pipes, and vents that discharge pollutants as continuous point sources; among them, the discharge outlets placed on the ground are called ground point sources, and those located at high altitudes are called point sources. is an elevated point source;
[0019] According to the Gaussian diffusion model, the present invention is based on the following assumptions: 1. the average flow field of the wind is stable, the wind speed is uniform, and the wind direction is straight; Conservation of mass in diffusion; ④ source intensity of pollution source is uniform and continuous.
[0020] b. Take the projection point o of the point source on the ground as the coordinate origin, and then use ...

The invention discloses a particulate matter maximum ground concentration predicating method, which comprises the whole steps of setting a continuous point source; performing space positioning on a high elevated point source; obtaining a particulate matter maximum ground concentration predicating model on the basis of a Gauss diffusion mode; performing comparison and analysis on the particulate matter maximum ground concentration of a plurality of continuous point sources according to the predicating model, and performing traceability and influence predication on pollutants. The method has the advantages that the Gauss mode is flexibly used; the operation is simple; the operation cost is low; when the method is applied to the practical service field of environmental protection department, the particulate matter maximum ground concentration can be obtained only through measuring the enterprise pollutant discharging parameter and the peripheral environment condition parameter; in addition, the precise positioning on the pollution source is realized by comparing and analyzing the particulate matter maximum ground concentration of the plurality of continuous point sources, so that the law enforcement of environmentalists is assisted; the law enforcement labor and the material resources are saved to the greatest degree; the environment influence results caused by enterprise pollutant discharge can be better controlled.
Description
technical field [0001] The invention relates to a prediction method, in particular to a method for predicting the maximum concentration of particulate matter falling on the ground, and belongs to the technical field of environmental monitoring. Background technique [0002] The atmosphere is one of the basic elements of the environment on which human beings depend, and it is also the direct object of environmental management. One of the main causes of air pollution is the sewage discharge of key pollution source enterprises. Therefore, in addition to the diffusion and dilution of pollutants by the turbulent mixing of the atmosphere, it is also necessary to trace the source of key pollution source enterprises, so as to fully supervise the installation of pollution source enterprises. Dust removal and exhaust gas purification devices can control the emission of air pollutants from the source. [0003] Under the current national conditions of our country, the work of controlli...
