Abstract

The invention relates to the technical fields of environmental protection and soil remediation, in particular to an in-situ remediation system for organic matter-contaminated soil. The system comprises a soil gas extraction part, an extraction well part, a chemical storage tank part and a chemical liquid pool part, wherein the soil gas extraction part is connected with the extraction well part by a first pipeline, the chemical storage tank part is connected with the chemical liquid pool part by a second pipeline, and the chemical liquid pool part is arranged above the extraction well part. The in-situ remediation system for the organic contaminated soil has the advantages of reasonable design, simple and convenient operation, good soil remediation effect, short treatment time, less work limitation and high applicability, and is especially suitable for the remediation of low permeability soil which is more difficult to treat; furthermore, the in-situ remediation system also has the advantages of being high in systematic degree, convenient to move, convenient for transferring operation and the like, thus being a comparatively ideal soil repair system at present.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and soil remediation, and in particular relates to an in-situ remediation system for soil polluted by organic matter. Background technique [0002] At present, with the rapid development of industry and agriculture, more and more organic pollutants enter the soil. At the same time, with the requirements of urban planning for the relocation of enterprises, a large number of industrial legacy sites need to be developed and reused urgently, and most of these sites have soil pollution. Threatening the health and environmental conditions of the surrounding residents, effective measures are urgently needed to deal with it. Volatile and semi-volatile organic pollutants are one of the main pollutants in such polluted sites. Such pollutants exist in the soil for a long time, causing serious harm to aboveground plants and underground organisms. Shallow groundwater affects drinking water so...
