Example Embodiment

[0018] Example: This example uses a certain site as an example. The site was originally a pesticide factory for the production of organic pesticides. Due to the residues of raw materials and process products in the production process, the site was polluted to a certain extent; according to the plan, the site will be refurbished It is developed and utilized as commercial, office and residential land, so it is necessary to carry out necessary investigation and assessment of the soil pollution status. After on-site investigation, the color of the soil in the site is abnormal, the water body in the puddle in some areas is yellow, and there are oil flower-like substances floating on the water surface; the soil smells pungent, accompanied by the smell of pesticides. This phenomenon may be related to the long production history of the plant. Relevant; according to the preliminary data collected, the main products used and produced by the plant are insecticides, fungicides, herbicides,...

Abstract

The invention discloses a site contaminated soil distribution determination method based on geological conditions. The method includes the following steps: 1) collecting the geological parameters of a to-be-tested site, comprising: soil geologic stratification, soil layer permeability, soil granular size, soil organic substance content, and water level, flow direction and flow speed of underground water, and determining the background values of the parameters; 2) collecting the environmental data of the site to determine the types of the pollutants; 3) determining investigation depth according to the types of the pollutants and the soil layer permeability coefficient; and 4) determining investigation zones according to the soil layer permeability coefficient, the soil organic substance content, and the water level, the flow direction and the flow speed of underground water. The method, on the basis of the character analysis of geological conditions, can be used for macroscopically determining and investigating the characters of distribution and migration of local soil pollutants with combination of the environmental data through various test methods. The method is low in workload, is short in period and is low in cost. A diagnosis result can effectively guide arrangement of sampling points and determination of sampling depth in site environment investigation in later period.

Description

technical field [0001] The invention belongs to the technical field of environmental geotechnical engineering, and in particular relates to a method for discriminating distribution of polluted soil on a site based on geological conditions. Background technique [0002] With the rapid development of society and economy, the level of urbanization has been continuously improved, but the environmental pollution has become increasingly serious, seriously destroying the ecosystem and affecting the quality of life and health of human beings. In the process of redevelopment of contaminated sites, comprehensive and accurate site surveys are very important to prevent and control ecological accidents at construction sites and construction safety accidents caused by soil and groundwater pollution. [0003] At present, site pollution investigations mainly rely on on-site sampling and laboratory testing and analysis methods. The test period is long, the sampling points are relatively rand...
