Soil electrodynamic restoration device and method based on rotating electrode

Abstract

The invention relates to the technical field of soil remediation treatment devices, in particular to a soil electrodynamic force remediation device and a soil electrodynamics remediation method based on a rotating electrode. The soil electrodynamic force remediation device comprises a soil remediation groove with the rotating electrode, a current transformation controller, an electrode transformation controller, an additive storage tank and an electrode liquid mixing tank, wherein the rotating electrode comprises a zero columnar electrode part and six rectangular plate electrode parts; the zero columnar electrode part is arranged in the middle of the soil remediation groove; the six rectangular plate electrode parts are arranged at the periphery of the soil remediation groove; an electrode pool surrounds the soil remediation groove; an electrode liquid collecting groove communicated with the electrode pool surrounds the electrode pool; the electrode liquid mixing tank is communicated with the soil remediation groove through a mixed liquid delivery pump; and the additive storage tank is communicated with the soil remediation groove through an additive delivery pump. The soil electrodynamic force remediation device does not generate secondary pollution, and organic pollutants in soil can be thoroughly oxidized and decomposed to form micromolecule innoxious substances such as water and carbon dioxide.

Description

technical field [0001] The invention relates to the technical field of soil organic pollutant treatment devices, in particular to a soil electrodynamic restoration device based on a rotating electrode and a method thereof. Background technique [0002] In recent years, the problem of soil environmental pollution has become more and more prominent, especially the pollution of organic matter in the soil. The pollution of soil organic matter in some discarded and relocated pesticides and chemical enterprise sites is particularly serious, and some seriously affect people's normal life. At the same time, persistent organic pollutants (POPs) have low water solubility, high fat solubility, semi-volatility, and refractory properties. Large range and long duration. Therefore, people pay more and more attention to soil organic pollution. [0003] At present, the control technologies of soil organic pollution mainly include leaching method, phytoremediation method, microbial remediat...
