An electrochemical device for controlling organic and inorganic pollution in soil and groundwater and its application

Abstract

The invention discloses an electrochemical device for treating pollution caused by organic matters and inorganic matters in soil and underground water and an application thereof. The device is characterized by being a control circuit which consists of a power supply, a control pivot and an electrode pack or electrodes, which are sequentially connected in series through leads, wherein the electrode pack or the electrodes are embedded into a pollution medium, and a conductive ionic catalytic liquid is added into the pollution medium; the control pivot receiving current output by the power supply adjusts output to the electrode pack or the electrodes so as to control the voltage, the polarity and / or the current direction of the electrode pack or the electrodes. The device disclosed by the invention can effectively promote degradation of pollutants in soil and underground water and improve the degradation efficiency of the pollutants without secondary pollution, so that the purpose of repairing soil is realized by treating organic and inorganic pollutants in soil and underground water.

Description

technical field [0001] The invention relates to the field of soil and groundwater pollution control, more specifically an electrochemical device for controlling soil and groundwater pollution by organic and inorganic substances and its application. Background technique [0002] There are many types of pollutants contained in soil and its groundwater, which can be summarized as organic pollutants and inorganic pollutants (including metals). Although natural soil and groundwater may contain pollutants (such as arsenic, lead and other heavy metals), the vast majority of high-concentration pollutants come from human industrial and agricultural activities. Existing methods for soil pollution control include physical (such as excavation, soil replacement, mechanical soil washing), chemical (such as oxidation, reduction) and biological (such as microbial degradation, phytoremediation, etc.) and other methods. Among them, in view of the fact that some polluting media need to be tre...
