Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] see Figure 1-2 , the embodiment of the present invention includes:

[0021] An electrothermally enhanced in-situ chemical oxidation repair device for organically polluted sites. Chemical oxidants are injected during restoration, and heating is used to activate the oxidants to promote the generation of oxidative free radicals, improve the utilization rate of chemicals, and make the chemicals in the soil The diffusion in the middle is more active; at the same time, a DC weak electric field is applied in the so...

Abstract

The invention discloses an electric heating enhanced in-situ chemical oxidation remediation device for an organic contaminated site, and the device comprises an injection heating unit, an electric enhancement unit, an extraction unit and a monitoring unit, wherein the monitoring unit is connected with the heating unit, the electric enhancement unit and the extraction unit so as to perform real-time monitoring and control. With the adoption of the manner, according to the electric heating enhanced in-situ chemical oxidation remediation device for the organic contaminated site, an in-situ chemical oxidation technology is coupled with an electrokinetic remediation technology, and an electric field is applied to contaminated soil, so that the effect of promoting migration of substances in thesoil can be achieved; the device has the remarkable advantages of being capable of being used for low-permeability soil and free of secondary pollution; meanwhile, the thermal function is added in theinjector, the agent utilization rate and the remediation effect are remarkably improved, the technology application scene is wider, cost waste is effectively avoided, and the defects existing in an original in-situ chemical oxidation technology are overcome.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an electrothermally enhanced in-situ chemical oxidation remediation device for organic polluted sites. Background technique [0002] In recent years, with the continuous development of my country's industrial sector, the problems of contaminated sites have gradually emerged. It is imperative to seek a contaminated site remediation technology with good remediation effect and low secondary pollution. The in-situ chemical oxidation technology injects chemical agents into the polluted site to oxidize organic pollutants, transforming macromolecular organic pollutants into small molecules or directly mineralizing them, so as to achieve the repair effect. [0003] In-situ chemical oxidation technology has the characteristics of simple construction and short remediation period, and is widely used in the actual remediation of contaminated sites. However, since this technology ma...
