- W2321863109 abstract "본 연구에서는 다양한 호기/혐기조건에서 유류오염물질인 및 MTBE의 생분해 특성을 비교하고, 특히 탈질 조건에서 질산염 영향을 조사하여 유류오염지역의 혐기적 자연정화방법의 적용 가능성을 평가하고자 한다. 단일기질 및 혼합기질 분해실험 결과, BTEX는 3가지 실험조건에서 차이는 있었으나 모두 분해가 일어났다. 그러나 benzene과 p-xylene은 호기성 조건에서 초기 공급된 용존 산소의 부족으로 인하여 분해가 지연되는 것으로 나타났다. 또한 혼합기질에서는 단일기질에 비해 BTEX 분해가 기질 경쟁관계로 인해 다소 지연되는 경향이 관찰되었다. MTBE는 탈질 조건에서만 생분해가 관찰되었으나, TBA 축적 없이 <TEX>$CO_2$</TEX>로 무기화되는 것으로 추정된다. 또한 BTEX 및 MTBE 분해에 대한 질산염 농도의 영향 실험 결과, 저농도(>50 mg/L)에서 BTEX 분해는 제한되었으며, 고농도 질산염(<200 mg/L) 조건하에서는 BTEX 분해가 억제되는 현상이 관찰되었다. 본 연구에서 도출된 결과는 유류오염지역의 경우 호기/혐기성 조건에서 자연 생분해를 유도할 수 있을 것으로 예상된다. The objectives of this study were to determine biodegradation and characteristics of BTEX and MTBE under aerovic-anaerobic conditions and evaluate the potential of natural attenuation method in denitrifying condition.. In the single-substrate experiments, all of the BTEX compounds were degraded under all the conditions. but, lower degradation of benzene and p-xylene were observed under aerobic condition due to the lack of oxygen initially supplied. In the mixed-substrate experiments, BTEX degradation was delayed compared to that in the single-substrate experiments due to a competition of the substrates. Biodegradation of MTBE was observed only under denitrifying conditions and we expected that MTBE mineralized to <TEX>$CO_2$</TEX> without the accumulation of TBA. We also conducted to determine the effect of initial nitrate concentration on BTEX and MTBE degradation. At low nitrate concentration (<50 mg/L), BTEX degradations were limited by the lack of electron acceptor and BTEX degradation was inhibited at high nitrate concentration (>200 mg/L). The results in this study indicated that biotransformation could be applied to the gasoline-contaminated region under aerovic-anaerobic." @default.
