Abstract

The invention discloses in-situ remediation equipment for organically contaminated soil and underground water. The in-situ remediation equipment comprises a central control system, an air compressionsystem, an ozone generation system, a gas distribution system, a reagent dissolving preparing system, an injection well system and a monitoring well system. Free radicals generated by the remediationequipment comprise OH* and SO4<->*, more types of organic matters can be oxidized, the reaction duration time is longer, and no secondary pollution is caused by an adopted oxidizing agent; sodium persulfate can be activated by reaction of hydrogen peroxide and ozone, so that additional activation conditions are avoided, and the economical benefit is improved; high-pressure air can promote transmission of chemicals, the influence radius is effectively increased, and blockage of the injection well is avoided. In addition, the in-situ remediation equipment is further provided with the monitoringwell system, the underground water quality and pollutant concentration can be monitored in real time, and a basis is provided for change of the agent adding amount. Automatic control over medicament transmission and real-time feedback of water quality and pollutant data are achieved, and meanwhile organic pollution in soil and underground water is remediated.

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 dissolved, 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, a...
