Problems solved by technology

[0002] The current air pollutant emission inventory is usually obtained based on survey and statistical methods, so the workload is heavy and the cycle is long, and only the results of the previous year can be obtained each year
However, under the current environmental management situation, the emissions of air pollution sources change rapidly with the implementation of governance or control measures, resulting in deviations between the original inventory and the current actual emissions, thus affecting the current air quality simulation results and air quality forecast results. the accuracy of

Embodiment Construction

[0054] The technical solutions of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0055] The air pollutant discharge inventory mentioned in the present invention refers to a data set of one or more pollutants discharged into the atmosphere by various pollution sources based on the classification of pollution sources in a certain geographical area within a certain period of time. And the information that described point source air pollutant discharge inventory comprises is longitude coordinate and latitude coordinate, chimney height (m), chimney outlet internal diameter (m), chimney exhaust temperature (K), flue gas velocity (m / h) and Emission of each pollutant (particulate matter is g / h, gaseous pollutant is mol / h.

[0056] Such as figure 1 As shown, it is a block diagram of the steps of the method for correcting and correcting the original input air pollutant emission inventory data o...

Abstract

The invention discloses a gridding data-based point source atmospheric pollutant emission list verification method, which is used for verifying a simulation result of a high-resolution list by the gridding monitoring data, wherein the gridding monitoring data is obtained from real air quality data with high temporal-spatial resolution. Originally input list data is adjusted through deviation between a simulation result and a real result, checking of an original list can be achieved, and the method has obvious advantages especially for checking of key point sources with large influences on local air quality.

Description

technical field [0001] The invention relates to the field of environmental protection monitoring, in particular to a gridded data-based verification method for a point source air pollutant discharge inventory. Background technique [0002] The current air pollutant emission inventory is usually obtained based on survey and statistical methods, so the workload is heavy and the cycle is long, and the results of the previous year can only be obtained each year. However, under the current environmental management situation, the emission of air pollution sources changes rapidly with the implementation of governance or control measures, resulting in deviations between the original inventory and the current actual emission, thus affecting the current air quality simulation results and air quality forecast results. the accuracy. [0003] Therefore, there is an urgent need for a method that can use the existing high-reliability data to evaluate it, find out the data areas with large...
