AI Technical Summary

Technical Problem

Existing electroosmosis technology suffers from electrode corrosion and unsatisfactory removal effects when treating heavy metal pollutants in soil, especially when the concentration is high, making it difficult to meet the regulatory requirements. There is a need to develop a device with a simple structure and easy operation to remove heavy metal pollutants quickly and effectively.

Method used

An electroosmosis system is used, including electrode plates and electrode tubes. An electroosmosis enhancement liquid is injected through an injection system to remove heavy metal pollutants using an electric field. The pollutants are then discharged through a pumping system. Hollow tubes made of EKG material are used as electrode tubes, which are wrapped with filter cloth and connected to the infusion pipeline. They are protected by woven geotextile and a sealing membrane.

Benefits of technology

It achieves rapid and effective removal of heavy metal pollutants from soil in a short time, is applicable to soil layers of various depths, and has a simple structure, convenient operation, and strong adaptability.
