Abstract

The bioreactor method, in which leachate is reinjected into a landfill for rapid decomposition and stabilization of buried waste, is being applied and tested at many landfills because of its numerous advantages. To apply the bioreactor method to a landfill successfully, it is very important to understand the behavioral characteristics of the injected leachate. In this study, electrical resistivity monitoring was performed to estimate the behavior of a landfill leachate in Korea where the bioreactor method was applied. For the electrical resistivity monitoring, a baseline survey was conducted in August 2013 before the leachate was injected, and time-lapse monitoring surveys were conducted four times after injection. The electrical resistivity monitoring results revealed reductions in electrical resistivity in the landfill attributable to the injected leachate, and the change in its characteristics over time was confirmed. In addition, by newly defining the electrical resistivity change ratio and applying it in this study, the spatial distribution and behavior of the leachate over time were effectively identified. More research on optimization of data acquisition and integrated monitoring methods using various techniques should be conducted in the near future.

매립된 폐기물의 빠른 분해 및 안정화를 위해 매립지에 침출수를 재주입하는 바이오리액터 공법은 많은 장점을 가지고 있어, 여러 매립지에서 시도되고 적용되고 있다. 매립지에 바이오리액터 공법을 성공적으로 적용하기 위해서는 주입된 침출수의 거동 특성을 파악하는 것이 중요하다. 본 논문에서는 바이오리액터 공법이 적용된 국내 매립장에서 침출수 거동을 파악하기 위해 전기비저항 모니터링을 수행하였다. 전기비저항 모니터링은 침출수가 주입되기 전인 2013년 8월에 기준 탐사를 수행하였고, 이후 주입에 따른 시간 경과 모니터링 탐사를 4회 수행하였다. 전기비저항 모니터링 결과로부터 침출수 주입에 따른 매립지 전기비저항 감소를 확인하였고, 시간에 따른 변화양상을 파악하였다. 또한, 전기비저항 변화비를 새롭게 정의하고 적용함으로써 침출수의 시간에 따른 공간적 분포 및 거동을 효과적으로 파악하였다. 향후에는 자료획득 최적화 연구와 다양한 기법들을 활용한 복합 모니터링 연구가 추가로 진행되어야 할 것으로 판단된다.
