Microwave in situ Remediation of Soils Polluted by Volatile Hydrocarbons

摘要

Microwaves as a tool for remediating soils contaminated by Volatile Organic Compounds (VOC) appear to be attractive for the advantages they offer, such as reduced thermal gradients, selectivity, possibility of in situ operation, time and money saving. The Microwave Induced Steam Distillation process (MISD) has been performed, to remediate a naphthalene polluted soil, using a closed applicator and an open applicator prototype designed and constructed for in situ treatments. Results showing the feasibility and advantages of this technique are presented and discussed. In particular they show that MISD can be effective for in situ treatment of the VOC polluted soils if contamination does not interest excessively deep layers.
