Problems solved by technology

[0004] It can be seen that since the compilation of emission source inventory requires a lot of investigation work, it is time-consuming and labor-intensive, and the compilation cycle is long.
When actually applied to air pollution traceability, changes in pollution source emissions due to industrial adjustments may not be reflected in the emission source inventory data in a timely manner, affecting the accuracy of air pollution traceability

Embodiment Construction

[0033] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0034] When the environmental monitoring data show that at t 1 The concentration of pollutants exceeds the standard at any time. In order to trace which emission sources caused the main pollution and the contribution rate of these emission sources, it is necessary to start the air pollution traceability system for calculation and analysis.

[0035] In order to control the calculation amount of retrospective analysis, the starting time of tracing pollution sources is limited to a certain historical time t 0 , according to practical experience, due to the effects of atmospheric transmission, diffusion dilution, etc., the main impact of pollutants emitted by pollution sources on local pollution usually does not exceed 72 hours, then (t 0 ,t 1) can be selected as 72 hours.

[0036] To trace back (t 0 ,t 1 ) time period each emission source pair t 1 The c...

Abstract

The invention discloses an air pollution tracing method and a device based on emission source monitoring data. The method comprises the steps of acquiring the emission source monitoring data and the statistical law thereof in advance; after the pollution tracing process is started, calculating emission source data based on the monitoring data of the tracing time period; when the change of the monitoring data does not accord with the statistical law, correcting the emission source data according to different situations: if the emission source monitoring equipment is judged to have an equipmentfault or a communication fault, predicting the emission source data by using the statistical law; if an enterprise production reason is determined according to the environment monitoring data, performing emission source data correction according to reason classification; and finally, replacing the content of the corresponding emission source in the emission source list with the processed emissionsource data, and inputting the adjusted emission source list and the meteorological field forecast data into an air pollution tracing system to obtain an air pollution tracing result. By using the method and the system, the pollution source emission change can be reflected to the emission source data in time, so that the air pollution tracing accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of air pollution traceability, and in particular relates to a device for an air pollution traceability method based on emission source monitoring data. Background technique [0002] Tracing the source of air pollution is an important scientific basis for the study of atmospheric environmental governance and control countermeasures. Based on the list of emission sources, meteorological field forecast data and environmental monitoring data, etc., apply the air pollution traceability model system to quantitatively analyze the pollution contribution rate caused by emission sources in different industries, regions, and time periods, so as to trace the source of air pollution and sharing rate. [0003] The emission source inventory data used in the current air pollution traceability technology is based on the investigation and data processing of pollution sources. The compilation of the emission source inventory...
