Abstract

The invention discloses an integrated remediation system for strengthening soil vapor extraction and groundwater remediation, which includes a nutrient storage tank, a microbial fermentation tank, a vapor extraction system, an aerating system and bio-carbon. The vapor extraction system includes a vapor injection device, a vapor injection pipe, a vapor injection well, a vapor extraction integrateddevice and a vapor extraction well. The vapor injection device is used for injecting vapor into the vapor injection well through the vapor injection pipe. The vapor extraction well is connected with the vapor extraction integrated device through the vapor extraction pipe. According to the remediation system, the advantages of microbial remediation, vapor extraction remediation, aerating remediation and bio-carbon adsorption are integrated, the remediation of soil and groundwater can be carried out at the same time. The remediation effect and the remediation efficiency are improved. The equipment is simple in installation and the operation cost is low.

Description

technical field [0001] The invention belongs to the technical field of in-situ restoration of soil and groundwater pollutants, and in particular relates to an integrated restoration system for strengthening soil gas phase extraction and groundwater restoration. Background technique [0002] Due to their unique biological activity, microorganisms can degrade various organic substances. Using this characteristic of microorganisms, people have widely used microorganisms in sewage treatment and soil remediation. In-situ bioremediation technology refers to a process in which natural or cultured microorganisms are used to degrade or transform harmful pollutants in polluted areas. It belongs to the category of environmental remediation and is a branch of bioremediation. Bioremediation originated in the 1970s and has become an important direction of technological development in the field of environmental engineering. Bioremediation technology is the most valuable and vital biologi...
