Title:
DEVICE AND APPARATUS FOR TREATING ORGANIC POLLUTANTS IN SOIL AND UNDERGROUND WATER
Document Type and Number:
WIPO Patent Application WO/2021/120860
Kind Code:
A1
Abstract:
Disclosed are a device and an apparatus for treating organic pollutants in soil and underground water. The device for treating the organic pollutants in soil and underground water comprises: a tank body, an electrolyte, a rectifier and an electrode assembly. The electrolyte contains a remedial agent for providing oxidizing charged ions, and the rectifier is used for connection to an alternating-current power supply to provide a pulsating direct current. During use, the rectifier is connected to the alternating-current power supply, and the electrolyte enters the organic pollutants in the soil and the underground water under the action of electromigration. The pulsating direct current converts some electric energy into heat energy while coming into contact with the organic pollutants in the soil and the underground water, and the remedial agent in the electrolyte is promoted to release the oxidizing charged ions. A redox reaction occurs between the oxidizing charged ions and the organic pollutants in the soil and the underground water for in-situ degradation of the organic pollutants in the soil and underground water. The treatment process is simple, and the operation is easy.
