Example Embodiment

[0021] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] With the increase of investment in air pollution control, the monitoring methods have been diversified. In the existing technology, two types of air quality models are usually used to evaluate the contribution of pollution sources to PM2.5 concentration. The two commonly used models are the second-generation diffusion model an...

Abstract

The invention provides a method and a device for calculating contribution of a pollution source to PM2.5 and electronic equipment, and relates to the technical field of atmospheric environment pollution prevention and control, the method comprises the following steps: calculating the molecular transformation ratio of gaseous pollutants according to PM2.5 component monitoring data, simulating the primary PM2.5 concentration of a target pollution source at an acceptor point and the primary contribution concentration of the gaseous pollutants to PM2.5, multiplying the primary contribution concentration of the gaseous pollutants by the molecular transformation ratio and multiplying the converted molecular mass to obtain secondary contribution concentration, and finally adding the secondary contribution concentration and the primary PM2.5 concentration to obtain the total PM2.5 contribution concentration of the target pollution source to the receptor point. By means of the method, the PM2.5 total contribution concentration can be obtained based on the secondary contribution concentration and the primary contribution concentration calculated according to the molecular transformation proportion, the requirements for hardware resources and lists can be simplified, therefore, the time for evaluating the PM2.5 total contribution concentration of a pollution source is shortened, and the calculation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of atmospheric environment pollution prevention and control, in particular to a method, device and electronic equipment for calculating the contribution of pollution sources to PM2.5. Background technique [0002] Fine particulate matter PM2.5 (fine particulate matter) is the main pollutant of autumn and winter smog. Its source includes primary source and secondary source. The primary source includes PM2.5 directly emitted by the pollution source, and the secondary source is gaseous pollution emitted by the pollution source. The physical and chemical reactions of substances such as SO2, NOx, etc. in the air are generated. Large-scale monitoring of PM2.5 concentration began in 2013, and then gradually carried out monitoring of PM2.5 components. Key cities in the plains, major provincial capitals and other cities all have PM2.5 component data. [0003] Usually, there are two ways to evaluate the contribution ...
