Resumo:
The use of thermal processes in order to remediate contaminated sites has been shown a great deal of promise, especially when time and effectiveness are considered. The present work describes the development of a new in situ device that simultaneously applies heat and delivers compressed air into the porous media. Additionally, a new set of instruments were also designed and built in order to monitor temperature and to extract vapor from the vadose zone. Tests performed at EMBRAPA Solos site and PUC-Rio Campus showed a good performance of the pieces of equipment developed. In addition, microbiological tests performed at the Geotechnical and Environmental Lab showed that is possible to recover the natural microbiota after prolonged exposure to temperatures above 400 ºC. Results have shown a recovery and stabilization of the population in about 3 weeks. However, it was also observed that metabolic activity was not fully recovered, in part due the lack of nutrients and organic matter in the porous media.
