Contaminated site soil-underground water integrated simulation remediation device and contaminated site soil-underground water integrated simulation remediation method

Abstract

The invention provides a contaminated site soil-underground water integrated simulation remediation device and a contaminated site soil-underground water integrated simulation remediation method. Thedevice comprises four parts of a soil column simulation device, a groundwater water simulation device, a rainfall simulation device and a monitoring device, wherein the soil column simulation device mainly comprises a cylinder body, a water permeable geotechnical cloth and a soil sampling port, the groundwater simulation device mainly comprises a box body, a groundwater injection port, a groundwater outflow port, a groundwater sampling port, a peristaltic pump, a water inlet and outlet pipe and a liquid storage tank, and the monitoring device comprises an integrated monitoring probe. Accordingto the device of the invention, the combined simulation of the rainfall permeation effect and the water flow permeation effect of the soil vadose zone is achieved by using the rainfall and seepage simulation device, and the temperatures of the soil layer and the groundwater layer, the pH value, the dissolved oxygen, the groundwater flow velocity and other parameters are real-timely monitored by using the integrated monitoring probe, so that the complex structure of the vadose zone can be accurately simulated, and the soil / groundwater integrated remediation simulation and remediation process monitoring and evaluation is realized.

Description

technical field [0001] The invention belongs to the technical field of contaminated site remediation research, and in particular relates to a soil-groundwater integrated simulated remediation device and method for a polluted site. Background technique [0002] Polluted sites refer to sites that are polluted by activities such as production, operation, processing, and storage of toxic and hazardous substances, stacking or disposal of hazardous waste, and mining activities that are harmful to human health or the ecological environment. With the development of my country's economy, the upgrading of industrial structure and the acceleration of urbanization, the soil left by some heavily polluting enterprises has also been polluted, and environmental hazards have become increasingly prominent. Due to the infiltration of precipitation or surface water, pollutants inevitably enter the groundwater through the soil, causing groundwater pollution. [0003] Soil can be divided into ae...
