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;

[0072] (2) Potential pollutants

Abstract

The invention relates to the technical field of groundwater treatment, and provides a method for determining the layered characteristics and preferential migration paths of groundwater pollution plumes, including the following steps: S1: pollution identification; S2: hydrogeological condition identification; S3: groundwater monitoring well points Slot arrangement; S4: Layered monitoring well construction; S5: Monitoring well washing and sample collection; S6: Sample detection; S7: Detection data analysis; S8: Determine the shape and layering of the groundwater pollution plume profile through the data analysis in step S7 feature. That is to say, by designing a three-dimensional water quality survey system and sampling monitoring, combined with three-dimensional simulation analysis of water quality data, the present invention achieves the purpose of describing the layered characteristics of the groundwater pollution plume profile and accurately identifying the priority migration path of the groundwater pollution plume.

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...
