Embodiment 1

[0068] 1. Pollution identification

[0069] (1) Potential sources of pollution

[0070] The production workshop, sewage treatment station and drying workshop in the investigation plot are potential pollution sources. The original solvent, production wastewater and waste liquid in the production workshop and drying workshop are scattered and leaked, causing pollutants to infiltrate and migrate, resulting in soil and groundwater pollution in the area; aging gaps at the bottom of sewage treatment stations, waste water pools, etc. cause pollutants to enter the soil and groundwater. Seepage migration;

[0071] According to hydrogeological analysis, area A of the project plot is located upstream of areas B and C, and the aquifer of the plot has good permeability and fluidity. The migration of polluted groundwater located in the upstream of the plot to the downstream may cause groundwater and soil pollution in the aquifer;

Abstract

The invention relates to the technical field of underground water treatment, and provides a method for determining underground water pollution plume profile hierarchical characteristics and a preferential migration path, which comprises the following steps: S1, identifying pollution; S2, identifying hydrogeological conditions; S3, carrying out underground water monitoring well point position arrangement; S4, constructing layered monitoring wells; S5, monitoring well washing and collecting samples; S6, carrying out sample detection; S7, analyzing detection data; and S8, determining the form andlayering characteristics of the underground water pollution plume profile through data analysis in the step S7. According to the method, a three-dimensional water quality investigation system and sampling monitoring are designed, and water quality data three-dimensional simulation analysis is combined, so that the purposes of depicting the layered characteristics of the underground water pollution plume profile and accurately identifying the preferential migration path of the underground water pollution plume are achieved.

Description

technical field [0001] The invention relates to the technical field of groundwater pollution, in particular to a method for determining the stratification characteristics and preferential migration path of a groundwater pollution plume profile. Background technique [0002] The existing survey methods for groundwater quality are based on the assumption that pollutants migrate and distribute uniformly in the same aquifer, but the actual situation is that if there are different water-bearing media in the same aquifer, the migration speed of pollutants will be different, forming a pollution plume. Stratified distribution. Because the permeability coefficients of different water-absorbing media are different, pollutants migrate preferentially along the water-absorbing media with high permeability rates, resulting in higher pollutant migration rates than other water-absorbing media. If the risk control is carried out according to the homogeneous speed, it will not achieve the id...
