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 discloses a monitoring point optimized layout method for emergency monitoring of sudden atmospheric pollution accidents, and belongs to the technical field of environmental risk early warning and evaluation. According to the method, a pollutant diffusion model is used for determining the diffusion range and concentration distribution characteristics of pollutants after an accident occurs, and the point distribution range is meshed based on the down-wind direction environment sensitive point distribution characteristics; the uncertainty among influence factors of emergency monitoring distribution points such as geography and environment sensitive source distribution is quantitatively processed through a fuzzy evaluation theory, different grids are screened in combination witha post-optimization technology based on clustering analysis, and the positions and the number of emergency monitoring points are determined according to the monitoring resource quantity. According tothe optimized stationing method, uncertainty existing in optimized stationing is quantitatively converted and processed, the influence of different factors on monitoring stationing is represented, andthe defect that emergency monitoring stationing of sudden atmospheric pollution accidents can only refer to monitoring specifications and historical working experience of conventional pollutants is overcome.

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...
