Abstract

The invention provides a method and device for evaluating effects of smoke pollutant discharge of a power plant on regional atmospheric haze. The method and device are used to evaluate the effects of the pollutant discharge of the power plant to be built on the regional atmospheric haze. The method comprises the steps that basic information of the power plant to be built is determined according to a typical power plant database which is established in advance; according to the determined basic information of the power plant to be built as well as data of a selected discharge model database, a discharge list is determined; a weather initial field is determined according to regional geographic data and a WRF-CHEM model; data of atmospheric pollutants, such as traces, diffusion and sedimentation concentrations and diffusion scopes, is determined according to the discharge list and the weather initial field; and evaluation results are generated according to GIS geographic information and the data of the atmospheric pollutants, such as the traces, diffusion and sedimentation concentrations and diffusion scopes.

Description

technical field [0001] The invention relates to environmental impact assessment technology, in particular to a method and device for evaluating regional atmospheric haze caused by flue gas pollutant discharge from a power plant. Background technique [0002] As China pays more and more attention to environmental protection, especially atmospheric smog, when building a new power plant or planning power construction, it is necessary to know how much air pollutants the new power plant brings to the region and the quantitative impact on the smog in the region . Therefore, it is urgent to establish a model that can quickly, scientifically and accurately evaluate the impact of thermal power plant flue gas particles on regional haze. [0003] Existing technologies can only conduct environmental impact assessments for power plants that have been put into operation, but cannot perform calculations for power plants that have not been built or are under planning.
