Abstract
A biological study was conducted to evaluate the enhancement of landfarming of soil contaminated with petroleum hydrocarbon (TPH) applying organic composite nutrients and a chemical oxidation during bioremediation. The target value of soil TPH after treatment was 500 mg/kg TPH. Addition of an organic compost and liquid swine manure for the removal of soil THP showed higher efficiency as 84.4% and 92.2% respectively than inorganic nutrients of 80.2%. In addition to the removal of non-biodegradable portion of residual hydrocarbons in soil, a chemical oxidation was applied during tailing period of the biological remediation, which showed high remediation efficiency as 98.1% compared with single bioremediation efficiency of 84.7%.

본 연구는 유류화합물로 오염된 토양의 생물학적 정화효율을 향상시키기 위한 연구로서, 정화목표인 TPH 500 mg/kg을 달성하기 위하여 유기성 영양분과 화학적 산화를 추가적으로 연계 적용하여 생물학적 정화효율의 성능향상 시험을 수행하였다. 경유로 오염된 토양을 대상으로 시험한 결과, 생물학적으로 정화하는 과정에서 무기성 성분(N, P)을 영양분으로 사용하여 정화한 경우에서 보다(정화효율 80.2%) 유기성 영향분인 퇴비와 액분을 사용한 경우가 각각 84.4%, 92.2%로 높은 정화효율을 보여주었다. 난분해성 물질을 함유한 토양의 생물학적 정화과정에서 tailing 현상이 일어나는 기간에 화학적 산화와 생물학적 정화를 병행하였을 때 TPH 농도를 134 mg/kg로 떨어뜨려 정화효율 98.1%를 얻은 반면에 생물학적 정화만 진행한 경우 TPH 1,073 mg/kg로 정화효율 84.7%를 나타내 화학적 산화의 병행처리가 더 효과적임을 알 수 있었다.
