Environmental capacity acquisition method and device based on O3 standard constraint

Abstract

The invention discloses an environmental capacity acquisition method and device based on O3 standard constraint. The environmental capacity acquisition method based on O3 standard constraint comprises the following steps: acquiring an environmental capacity input parameter set of a target year; converting NOx coefficients and / or VOCs coefficients in the environmental capacity input parameter set to generate an environmental capacity accounting parameter set; acquiring an air quality model; acquiring a reference O3 simulation concentration; acquiring an accounting O3 simulation concentration; obtaining a concentration reduction proportion through the reference O3 simulation concentration and the accounting O3 simulation concentration; and judging whether an accounting O3 simulation concentration reaches a first preset condition or not and a second preset condition is reached according to the concentration reduction proportion, and if so, acquiring an environment capacity accounting parameter set corresponding to the accounting O3 simulation concentration. According to the environmental capacity acquisition method based on O3 standard constraint, the whole process is not affected by human factors, the result is accurate, and compared with the prior art, material resources and manpower are saved.

Description

technical field [0001] This application relates to the technical field of environmental capacity, in particular to an O-based 3 A method and device for obtaining environmental capacity subject to standard compliance. Background technique [0002] At present, with the rapid development of my country's economy and the improvement of the level of industrialization and urbanization, the air pollution of major urban agglomerations in my country is being reduced by PM 10 , PM 2.5 The regional pollution problem characterized by a single pollutant is quickly transformed into an atmospheric environmental problem characterized by structural, compressed, and compound pollution. In recent years, the special measures for atmospheric control implemented in my country have continuously improved the ambient air quality. From 2016 to 2018, the national PM 2.5 , PM 10 , SO 2 and the proportion of CO concentration and the number of days exceeding the standard showed an obvious downward tr...

Problems solved by technology

[0004] In the existing technology, the drafting of the emission reduction plan is done subjectively, and there is no objective method for scientific drafting, so that the proposed emission reduction plan cannot achieve the intended effect or the proposed emission reduction plan needs to be adjusted several times. The situation of arranging plans occurs, wasting labor and time
