| 摘要 |
The present invention provides a method and a system (80) for removing contaminants from contaminated matter. The particulate matter (50) is leached with a lixivant solution (70) to produce a contaminated leachate (80), which includes contaminants from the particulate matter. The contaminants are then extracted from the contaminated leachate. In this manner, the extracted contaminants are removed from the particulate matter (50). In one embodiment, a remediation system is provided that includes a lixivant delivery system (100), a leaching system (200), and a leachate processing system (300). The leaching system leaches the particulate matter (50) with lixivant solution (70) from the lixivant delivery system. From this leaching, a contaminated leachate (80), which includes dissolved contaminants from the particulate matter, is formed. The leachate processing system (300) is connected to the leaching system to receive the contaminated leachate. The leachate processing system (300) extracts the contaminants from the contaminated leachate in order to remove them from the particulate matter.
