Application Status of Vertical Barrier Technology in Site Contamination Remediation

The development of industry has brought serious heavy metal pollution in the soil. There are various kinds of site contamination remediation technologies. The slurry wall barriers technology has many advantages, such as low permeability, good chemical compatibility, and low cost, so it was widely used in groundwater and soil pollution control projects. In this paper, the application status of vertical barrier technology in contaminated sites is reviewed. Currently, those research progress at home and abroad payed more attention on barrier materials, barrier mechanisms, and site types.
