Soil vapor extraction(SVE)has been effectively used for removal of volatile organic compounds (VOCs) from unsaturated soilIt is safe
economical and highly efficient.Columnventing experiment was used to simulate the SVE in the typical red earth in south China.Benzene
one of the most common VOCs
was selected as the single compound.Fluvo-aquic soil of Beijing and black soil of Jilin were selected as the control samples to study the effect of soil types on the SVE remediation process.Different soil water content on the venting behavior of a binary mixture (benzene and ethylbenzene) from the red earth was also investigated.The results showed that the best soil water content was 16.8 % at the 600 ml.min-1 vapor flow rate for the binary mixture.Control experiments indicated that soil type and soil organic matter were also key factors in SVE.
