Atmospheric environment capacity calculation method

Abstract

The invention provides an atmospheric environment capacity calculation method. The method comprises the following steps of: setting a staged environment protection target; setting different emission reduction situations by taking a fact that a pollutant environment concentration achieves the staged environment protection target as a constraint condition and combining a total pollutant amount emission reduction index requirement; carrying out environment effect simulation by utilizing an air quality model and a receptor model; and calculating a permissible total emission amount of atmospheric pollutants which satisfy an environment quality target and a total emission reduction amount index. The method has the beneficial effects of comprehensively considering dynamic changes of factors suchas meteorological resources of different seasons, production characteristics and pollution source emission manners of various industries and future development plans so as to realize optimal configuration of atmospheric environment capacity resources, determining that emission performance standards of various industries can represent the present advanced technological level so as to urge process reform and develop in the direction of energy-saving, low-emission and clean production, and considering source control and end treatment of pollutants so as to provide economic and technological feasibility and operability on the basis of satisfying environmental objectives.

Description

technical field [0001] The invention belongs to the field of atmospheric environment science and technology, and in particular relates to an atmospheric environment capacity calculation method. Background technique [0002] The traditional atmospheric environmental capacity estimation methods mainly include A-P value method, numerical model simulation method and linear programming method. [0003] The A-P value method is the simplest method for estimating the atmospheric environmental capacity. Its characteristic is that it does not need to know the layout, emission amount and emission mode of pollution sources. It can roughly estimate the atmospheric environmental capacity of the research area according to the area and natural conditions, which is simple and easy. , which has a certain reference value for decision-making and proposing regional total control indicators. However, the A-P value method is difficult to consider the impact of external pollution sources and local...

AI Technical Summary

Problems solved by technology

[0007] (1) The atmospheric environmental capacity accounting methods for gaseous pollutants have their own strengths, but the theoretically calculated allowable emissions of each pollution source have the problem of technical and economic feasibility

[0008] (2) The traditional total particulate matter control is only aimed at organized emission sources such as smoke and industrial dust, and cannot be directly linked to environmental quality, and cannot estimate the environmental capacity of particulate matter

[0009] (3) The traditional control of the total amount of air pollutants only calculates the environmental capacity of primary pollutants, without considering the relationship between gaseous precursors and secondary particles, and the secondary particles are important for PM 2.5 Concentration has a non-negligible effect

[0010] At present, the research areas of atmospheric capacity generally have the characteristics of large spatial scale and diverse emission sources, and air pollution is regional and complex, and the secondary pollution process cannot be ignored

In view of these characteristics, traditional environmental capacity technology methods such as A-P value method, numerical simulation method and linear programming method are not fully applicable.
