Study on the Interaction between the Reduction and Remediation of Dredged Sediments from Tai Lake Based on Vacuum Electro-Osmosis

The treatment of metal-contaminated sediment generated in environmental dredging projects often requires both reduction and remediation, the electric field has good application prospects integration remediation. In this study, based on electro-osmosis, vacuum, vacuum electro-osmosis methods, a detachable test system was made. Experiments three methods were carried out independently remediation dredged from Tai Lake under pollution-free Cu-contaminated conditions. results show that copper contamination weakens effect reduction, production precipitates makes soil more prone to cracking blocking drainage channels, which greatest impact method. terms concentration, achieves transport discharge contaminants, best effect. removal rates at anode cathode are 45.1% 50.0%, respectively. A correlation model electrical conductivity, moisture content, contaminant concentration established facilitate determination concentrations actual projects. Electro-migration plays dominant role process, affects distribution and, thus, migration efficiency.
