초록

The landfarming treatment for the remediation of the petroleum contaminated soil at the returned U.S. Military bases was investigated in this study. Specifically, the bioaugmentation performance using various commercially available petroleum-degrading bacteria was evaluated and the directions for enhancing the performance of the landfarming treatment were suggested. The environmental factors of the soils at the returned U.S. Military bases chosen for remediation indicate that the landfarming treatment can be used as the remediation technique; however, the addition of nitrogen or phosphorus is required. The lab-scale landfarming treatment tests using the model soil and the site soil showed that the degradation efficiency was greater with the model soil than the site soil and that the treatment performance was not affected by the number of bacteria present in the soil in the range of $10^6-10^{12}$ CFU/g. These results suggest that the successful landfarming treatment depends on the petroleum degradability of bacteria used and the environmental conditions during the treatment rather than the number of petroleum-degrading bacteria used.
