CONFORMATION OF HEAVY METAL SPATIAL DISTRIBUTION OF AN IN-PRODUCTION ENTERPRISE IN HUNAN BASED ON VOXLER SIMULATION
The in-production enterprise cannot layout sampling by grid comprehensively,due to the daily production,which leads to difficulties in identifying the spatial distribution of contamination.The article took a Hunan lead processing enterprise as the research object,using the spatial interpolation method of Voxler to supplement the blank area based on the detected results of the sampling points,and then drawing the spatial distribution map of the characteristic contaminants.The application of the Voxler spatial model showed the results as follows:on the one hand,Voxler could visually characterize the distribution of contaminants,and effectively fill in the lack of detailed inspection contents;on the other hand,compared with the traditional 2-D analysis model,it could provide more accurate area result of the contaminated soil.There was lead pollution in the entire factory area,and the area of contaminated soil exceeding the standard was about 340000 m3.The composite pollution of arsenic,cadmium,and lead under the smelting area,acid production area,and raw material storage area,had the volume calculated as about 130000 m3.The precise positioning and the precise measurement can provide design support for the later risk assessment and pollution control of similar enterprises.
