Embodiment Construction

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] The receptor model is to infer the type of emission source and its contribution to the receptor when the receptor component spectrum is known but the source spectrum is unknown, combining the identification components of each emission source and calculation results. Pollution sources are generally divided into dust sources, coal combustion sources, technological process source...

Abstract

The invention provides a source analysis method and device for particulate matter pollution, and relates to the technical field of pollution source analysis. The method comprises the following steps:obtaining meteorological data, particulate matters corresponding to a target region, and component data of the particulate matters; based on the particulate matter and component data, parsing according to a receptor model to obtain pollution source concentration data; performing image simulation based on the meteorological data, and determining an air mass track influencing the target area; and determining a potential source and a concentration weight of the pollution source in the target area based on the air mass track and the pollution source concentration data. Pollution source data of a target area are obtained through the receptor model, an air mass track of the target area is obtained based on meteorological data, the potential source area influencing the pollution source of the target area is obtained through a potential source contribution analysis method, and the problem of area transmission of a pollution source is solved.

Description

technical field [0001] The invention relates to the technical field of pollution source analysis, in particular to a source analysis method and device for particulate matter pollution in the atmosphere. Background technique [0002] In addition to local sources, particulate matter pollution also has regional transmission problems caused by climate and other influencing factors. Nowadays, the potential source contribution function (PSCF) combined with the concentration-weighted trajectory (CWT) method is generally used to confirm the pollution source areas that affect the air quality of the study area, and on this basis to analyze these potential sources. The influence degree of the environmental attributes of the source area on the target receiving area. Among them, the potential source contribution analysis method is a method to identify the source area based on the airflow trajectory analysis, also known as the residence time analysis method. PSCF can only use the propor...
