摘要:
Restoration of soils contaminated with hydrocarbons and metals is one of the most important problems of environmental protection. During the last 30 years, considerable progress has been made in the development of effective remediation technologies. Modern purging technologies are based on the chemical and biological degradation of contaminants and their conversion to safe forms or to intermediate substances convenient for transport in soils. To accelerate transport of contaminants or their intermediate substances in soils, electrical fields (direct current) are applied to zones being remediated. This allows the volumetric rate of transport to increase ≈ 50-60 times, and the substances to collect at convenient removal sites
