Problems solved by technology

[0003] Industrial sources and motor vehicle sources are the main pollution sources of ozone precursors VOCs and NOx. The existing methods for identifying the pollution sources of ozone precursors not only take a long time, but are also weakly targeted, and it is difficult to meet the requirements of the current atmospheric pollution. Requirements for refined pollution sources in environmental regulation
For example, in the prior art, it is usually only possible to determine the approximate area of ​​the high-value zone of ozone precursors, and it is difficult to confirm where the specific pollution source is; in addition, the impact of motor vehicle sources on the emission of ozone precursors is ignored, and it is difficult to Difficult to trace high-emission roads and specific information on high-emission vehicles

Abstract

The invention relates to an ozone precursor high-value region refined emission source tracing and positioning method and system. The method comprises the steps that the troposphere ozone precursor column concentration is obtained through a satellite remote sensing image; estimating the concentration of a near-surface ozone precursor through the concentration of a troposphere ozone precursor column so as to obtain an ozone precursor indication value; judging an ozone pollutant control type according to the ozone precursor indication value, and extracting an ozone precursor high-value region; obtaining the ozone precursor emission of the enterprises in the high-value area, and positioning the enterprises with the emission greater than a preset value; vehicle pollutant emission information of different emission standards on each road in the high-value area is obtained, the comprehensive emission amount of each road is calculated, and the road with the emission amount larger than the preset value is positioned, so that the vehicle with the high emission amount on the road is locked. According to the method, an abnormal emission and high emission industrial enterprise management and control list in an ozone precursor high-value region can be accurately screened out, the troubleshooting and management and control range is shortened, and the effectiveness and pertinence of management and control are improved.

Description

technical field [0001] The invention relates to a method, system and readable medium for traceability and positioning of refined emission sources in high-value areas of ozone precursors, belonging to the technical field of pollution source monitoring, and in particular to emission sources of ozone precursors. Background technique [0002] Near-ground ozone is produced by a series of complex photochemical reactions from precursors such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) under light conditions. It has strong oxidative properties and poses a threat to human health. , leading to diseases in the human cardiovascular and cerebrovascular systems, respiratory system, etc., and will also affect the global radiation balance, and have an impact on the global and local climate. [0003] Industrial sources and motor vehicle sources are the main pollution sources of ozone precursors VOCs and NOx. The existing methods for identifying the pollution sources of ozo...
