Abstract

The invention discloses an assessment method and device of gridding urban atmospheric pollutant emission, wherein the method includes performing grid division on a target area to obtain a plurality ofcontrol areas; determining key pollution sources; determining area pollutant emission levels of the control areas; obtaining distribution information of surrounding pollution sources; obtaining pollutant distribution diffusion information in different scenes according to the area pollutant discharge levels and surrounding pollution sources, and establishing a pollutant transfer mathematical model; determining maximum emission amount and allowed emission indexes, and determining environmental carrying capacity; and formulating emission reduction measures according to the environmental carryingcapacity and determining capacity allocation. The method can obtain the plurality of control areas through gridding of the target area, thereby determining the area pollutant emission levels of the control areas, and can obtain the environment bearing capacity according to the distribution information of the surrounding pollution sources, thereby formulating emission reduction measures and determining capacity allocation, accuracy and reliability of assessment are improved, and effective pollutant management and monitoring are realized.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to an evaluation method and device for gridded city air pollutant discharge. Background technique [0002] At present, with the rapid economic development, large-scale, low-efficiency energy consumption and uncontrolled pollutant discharge have caused a sharp outbreak of air pollution problems in cities across the country. For example, smog has become an issue that affects people's production, life and improvement The core problem facing quality. [0003] In related technologies, multi-scale analysis methods are mainly used for the analysis of regional atmospheric pollutant carrying capacity (for example, low overhead source (30m), ground base station (2km), aerial survey (30km), satellite remote sensing, etc.), through regional space volume and unit The pollutant concentration control index product is used to determine the regional pollutant carrying capacity, or t...
