Remediation Technology for the Restoration of Polluted Soil

Abstract

One of the most serious environmental issues is soil pollution. With the increase in contaminated sites, how to safely and effectively remediate these contaminated soils has become an urgent environmental problem in our country. This paper summarizes the most commonly used remediation technologies and research progress for contaminated soil in the United States and abroad, including physical remediation, chemical remediation, and bioremediation. Each repair technique has advantages and disadvantages. To get around the problems with a single method and make the most of the benefits of different remediation technologies, it was suggested that research and development of comprehensive remediation technologies for contaminated soils be stepped up.
