영문 초록

This study was conducted to evaluate the effect of initial concentration on pilot-sca]e composting of diesel-consoil. Sandy soil was used in this study. Target contaminant. diesel oil, was spiked at about 10.000. 25.000. and 50,000 mg TPH/kg of dry soil. Mix ratio of soil to sludge was I :0.5 as wet weight basis, Removal efficiencies for initial concentrations of 12,966, 23,894 and 51,042 mg TPH/kg were 90, 93 and 54%, respectively, during 33 days of composting. Normal alkanes in TPH ranged from 15 to 22% in initial soils. Volatilization of individual normal alkane in 1.999 mg n-alkanes/kg was completed within 4 days, while n-alkane compounds of C11-CI4 in 5,270 and 9,836 mg n-alkanes/kg were volatilized continuously during 33 days of composing operation. The first order degradation rate con-stants for 12,966,23,894, and 51.042 mg TPH/kg were 0.058, 0.076. and 0.022/day, and those for 1,997,5,270. and 9,836 mg n-alkanes/kg were 0.093. 0.100, and 0.019/day, respectively. Considering TPH removal rate, CO2 porduction rate. and dehydrogenase activity, the concentration of 51 ,042 mg TPH/kg inhibited biodegradation of diesel-composting.
