Embodiment 1

[0051] For verifying the excellent effect of the present invention, with SF 6 Leakage simulation experiments are used as a case to verify and evaluate the emergency monitoring and distribution technology for sudden air pollution based on the combination of diffusion model-fuzzy comprehensive evaluation-post-optimization analysis technology.

[0052] (1) Case description

[0053] SF 6 The leakage test site is located in the Horqin Grassland of Inner Mongolia (46.5°N, 122.8°E), the terrain is high in the west and low in the east (average altitude ~660m), mainly grasslands and hills ( figure 2 in a). SF 6 In the leak test, the gas release height is 10m, the release rate is 30kg / h, and the release time is 10min. The downwind direction adopts fan-shaped points with the dominant wind direction as the central axis, and the point coverage is 60°. A total of 34 sampling points are arranged, and the coordinate information of the sampling points is recorded ( figure 2 in b). Samp...

Abstract

The invention relates to an optimal layout method of monitoring points for emergency monitoring of sudden air pollution accidents, which belongs to the technical field of early warning and evaluation of environmental risks. The invention uses a pollutant diffusion model to determine the diffusion range and concentration distribution characteristics of pollutants after the accident, and grids the distribution range based on the distribution characteristics of environmentally sensitive points in the downwind direction; quantitatively handles geographical and environmental sensitivity through fuzzy evaluation theory According to the uncertainty among the factors affecting the distribution of emergency monitoring points such as source distribution, different grids are screened by combining post-optimization technology based on cluster analysis, and the location and quantity of emergency monitoring points are determined according to the amount of monitoring resources. The optimal distribution method quantitatively converts the uncertainties in the optimal distribution, characterizes the influence of different factors on the monitoring distribution, and makes up for the defect that the emergency monitoring distribution of sudden air pollution accidents can only refer to the monitoring specifications and historical work experience of conventional pollutants. .

Description

technical field [0001] The invention belongs to the technical field of early warning and evaluation of environmental risks, and specifically relates to a universal emergency monitoring and optimization point distribution technology for sudden air pollution accidents, and specifically relates to a technology based on pollutant diffusion model-fuzzy comprehensive evaluation theory-post-optimization analysis technology Emergency monitoring point optimization layout method. Background technique [0002] Sudden air pollution events such as leakage, fire, and explosion caused by the production, transportation, and management of hazardous chemicals have entered a period of high incidence, and have the characteristics of suddenness, dynamic changes in the pollution process, and complex environments, which seriously restrict the emergency monitoring and monitoring of accidents. Response disposal poses a huge threat to human health and the ecological environment. Conventional polluta...
