A method of accounting for atmospheric environmental capacity

Abstract

The present invention provides an atmospheric environment capacity accounting method, which sets environmental protection targets in stages, takes a pollutant environmental concentration to reach the environmental protection targets in stages as constraints, and combines the requirements of total pollutant discharge reduction indicators to set For different emission reduction scenarios, the air quality model and receptor model are used to simulate the environmental effects, and the total allowable emission of air pollutants that meet the environmental quality goals and the total emission reduction indicators is calculated. The beneficial effect of the present invention is to comprehensively consider the dynamic changes of factors such as meteorological resources in different seasons, production characteristics of various industries, pollution source discharge methods, future development planning, etc., to realize the optimal allocation of atmospheric environment capacity resources; to determine that the emission performance standards of various industries can represent the current The advanced technology level promotes its reform process and develops in the direction of energy saving, low emission and clean production; considering the source control and end treatment of pollutants, it strives to be economically and technically feasible and operable on the basis of meeting environmental goals.

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.
