Abstract
A biofilter study was performed in order to remove mixed benzene and ethylene emitted from soil and groundwater remediation. In particular, more than 96% of ethylene was removed at residence times of 10～15 min, and the possibility of use of the biofilter was obtained. The benzene removal efficiency was achieved as much as 100% at residence times of 2～15 min. With a residence time of 15 min, the maximum elimination capacity of benzene and ethylene was 4.3 g/$\textrm{m}^3$hr and 1.4 g/$\textrm{m}^3$hr, respectively. The maximum elimination capacity of benzene was 3 times higher than that of ethylene. Carbon dioxide concentration decreased as residence times were lowered due to low ethylene degradation rate. The maximum carbon dioxide production rate of 3,169 [mg-$CO_2$/(g-${C_2}{H_4}$＋${C_6}{H_6$)] was investigated when benzene and ethylene were completely removed. It was found that dominant bacteria in the benzene-degrading microorganisms were identified as Bacillus mycoides and Pseudomonas fluorescens. Dominant bacteria in the ethylene-degrading microorganisms were identified as Pseudomonas putida and Pseudomonas fluorescens.
