Natural Attenuation of BTEX in the Underground Environment
|
Abstract:
Columns filled with fine sands was constructed to evaluate the natural attenuation process of BTEX in the underground environment.It was found that the naturally attenuation of BTEX occurred.In this process,volatilization and biodegradation are the important mechanisms.Taking benzene for example,at the concentration of 11.40(mg/L),the relative proportions of volatilization and biodegradation accounting for natural degradation were 16.36% and 4.91%.Comparatively,at the concentration of 3.30(mg/L) for toluene...
