An in-situ remediation device for organically polluted soil and groundwater

Abstract

The invention discloses in-situ restoration equipment for organically polluted soil and groundwater. The restoration equipment includes a central control system, an air compression system, an ozone generation system, a gas distribution system, a dissolving agent system, an injection well system and a monitoring well system. The free radicals produced by the repair equipment of the present invention include OH, SO 4 ‑ ·, there are more types of organic matter that can be oxidized, the reaction lasts longer, and the oxidant used will not cause secondary pollution; through the reaction of hydrogen peroxide and ozone, sodium persulfate can be activated to avoid additional activation conditions and improve economic efficiency High-pressure air can promote the transmission of the agent, effectively increase the influence radius, and avoid the blockage of the injection well. In addition, the present invention is also equipped with a monitoring well system, which can monitor the groundwater quality and pollutant concentration in real time, and provide a basis for the change of the dosage of the medicine; realize the automatic control of the medicine transmission, the real-time feedback of the water quality and pollutant data, and restore the soil and pollutants at the same time. Organic pollution in groundwater.

Description

technical field

[0001] The invention relates to a repairing device, in particular to an in-situ repairing device for organically polluted soil and groundwater. Background technique

[0002] The environmental problems brought about by the increasing economic development of our country are becoming more and more prominent, and the problems of soil and groundwater pollution are gradually attracting attention. Organic pollutants are a common type of pollutants, which accumulate in the underground environment in the form of non-aqueous liquids, soil particles adsorbed and water-soluble, and can cause large-scale pollution through diffusion and migration. At the same time, due to the complex underground environment, it is difficult to control. Common repair techniques can be divided into heterotopic repair and in situ repair. Ex-situ remediation refers to excavation, extraction, etc., and post-processing, so that contaminated soil and groundwater leave the original location, and...
