Abstract

The invention provides an in-situ restoration device and an in-situ restoration method of organic polluted soil and underground water. The in-situ restoration device designed by the invention comprises a pneumatic source system, an agent dissolving and preparing system, an in-situ injection system and an injection well system. The in-situ restoration device is characterized in that the organic polluted soil and the underground water in a saturation layer and a non-saturation layer can be restored, injection wells are distributed at polluted areas according to the conditions of pollution distribution and hydrogeololgy and the like, and oxidizing agents prepared by the dissolving and preparing system are injected into the polluted areas by certain pressure through the injection system to restore target pollutants. The in-situ restoration device provided by the invention has the advantages that the injection wells are subjected to three-layer sealing by three sealing materials, the integration is good, the disassembly is fast and the economic and fast effects are achieved.

Description

technical field [0001] The invention relates to an in-situ remediation device and method for organic polluted soil and groundwater, and belongs to the technical field of in-situ soil remediation methods. Background technique [0002] At present, commonly used contaminated site remediation technologies include ex-situ and in-situ remediation techniques, which determines that contaminated site remediation equipment can also be divided into in-situ remediation devices and ex-situ remediation devices. Ectopic mainly refers to excavation and post-processing, that is, by means of machinery and artificial means, the soil is removed from its original position, and then processed, disposed and reused by various methods such as chemical physics or biology. Ex-situ restoration technology involves excavation and transfer, and there is a danger of secondary pollution in the process, which has obvious shortcomings. In situ repair technology has been widely used in recent years. Among th...
