토양경작법을 이용한 유류오염 토양 복원시 미생물제제 적용 효과

Landfarming and a microbial agent were used to treat dilsel-contaminated soil. The microbial agent was applied to the contaminated soil in a concentration of 5$\times$102 cfu/soil(g) and the total amount of microbial agent, 210 l , was sprinkled on the soil four times for 24 days during 50 day-remediation period. The remediation goal, lower than 800mg/kg of TPH, was achieved from 5,707mg/kg of TPH within 50 days. The total number and activity of indigenous microorganisms were increased by 100 times after the microbial agent, Bioil-D, was applied to the contaminated soil.

유류에 의한 오염토양의 정화방법에는 크게 물리화학적 처리기술과 생물학적인 처리기술로 구분할수 있으며 생물학적 처리기술은 물리화학적 처리기술에 비하여 복원 기간이 긴 반면 처리비용이 저렴하며 2차 오염원을 발생시키지 않는다는 장점이 있다.<중략>
