윤활유 분해 미생물을 이용한 철도 오염토양 처리방법에 대한 현장 연구

초록

Soil contamination around railroad turnout has been often caused by the drop of lubricant during its maintenance. Railroad site is difficult to stop the operation of rolling stocks for the treatment of contaminated soil. Thus, it is necessary to select an alternative remediation method. In this study, the bioremediation using microorganisms degrading lubricant was applied considering these status. As a result, the residual TPH concentration in soil was increased due to the continuous greasing of turnout even though the addition of microorganisms degrading lubricant.In the future, the change of biodegradable lubricant should be conducted simultaneously to prevent soil contamination around railroad turnout.
