Problems solved by technology

At present, the identification of soil remediation measures is based on the 3D simulation of the migration process of pollutants in the soil. The 3D migration of common soil pollutants can be realized through the EVS (EarthVolumetricStudio, visual geological modeling software) environmental visualization system and Voxler software. , but the three-dimensional irregular figure drawn is not suitable for actual soil remediation constr...

Abstract

The invention provides a method and a system for calculating soil remediation amount of a contaminated site, and the method comprises the steps: obtaining pollution risk distribution maps of differentsoil layers according to the soil sample data of the contaminated site; selecting an area of which the pollution risk level reaches a preset level as a to-be-repaired area, and simplifying the boundary contour of the to-be-repaired area according to a preset simplified tolerance; partitioning the pollutant migration depths of different soil layers by adopting a Thiessen polygon according to the soil sample data to obtain a pollutant migration depth block map; and superposing the pollution risk distribution map and the pollutant migration depth block map of the same soil layer, calculating thesoil remediation amount of the polluted site according to the to-be-remediated area on the superposition map, and obtaining the inflection point coordinates of the to-be-remediated area for soil remediation construction. The method is simple to operate and convenient for practical application, the contaminated site soil remediation amount can be scientifically and reasonably calculated, the sitesoil remediation treatment difficulty is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of site environment investigation, in particular to a method and system for calculating soil remediation amount of polluted sites. Background technique [0002] The environmental quality of my country's industrial and mining land is not optimistic. According to the "National Soil Pollution Survey Bulletin" in 2014, the soil points exceeding the standard rate of heavily polluted enterprise land, industrial waste land, industrial park, solid waste centralized treatment site and mining area were 36.3%, 34.9%, 29.4%, and 21.3%, respectively. % and 33.4%. In 2016, the total investment in environmental pollution control accounted for a relatively low proportion of 1.24% of GDP (data from the 2017 China Statistical Yearbook), which requires limited investment in pollution control. It is imminent to reduce the cost of environmental restoration and improve the quality of governance work. [0003] It is a feasible ...
