Abstract

The bioreactor type of landfill is to operate to enhance waste decomposition by continuously supplying water such as leachate and wastewater within the landfill, which helps increase the landfill gas production, which in turn prematurely stabilize the landfill. Recently, the environmental law for the operation of the bioreactor type of landfill has been enacted and thereafter the bioreactor type of landfill has been introduced for the first time in Korea to the SUDOKWON landfill site. In order to properly apply for bioreactor to the landfill, it is necessary to investigate the water distribution inside the landfill so that water recirculation should be optimally allocated with the zone of concern. In this regard, electrical resistivity survey has been suitably performed to delineate the water distribution in the landfill. That is, it has surveyed for long-term of period that the recirculation of leachate has been properly reflected from electrical resistivity within the second landfill of SUDOKWON landfill site. As a result, the electrical resistivity immediately corresponded to the variation of the extent of the seasonal temperature dynamics. From this, a calibratrion could be accomplished by correlating between temperature and electrical resistivity obtained from this study that can be applicable for optimally monitoring to keep the ideal operating condition for the bioreactor type of landfill.

바이오리액터형 매립지는 매립지 내부로 침출수나 폐수 같은 수분의 공급을 통하여 폐기물의 분해를 촉진하기 위하여 운영하며, 이러한 수분 공급은 매립가스를 증산하고 결국 매립지 조기안정화에 기여한다. 최근 바이오리액터형 매립지 운영을 위한 환경법이 제정되었으며 이에 따라 국내 최초로 수도권매립지에 도입하였다. 바이오리액터형 매립지의 안정적인 적용을 위하여는 매립지 내부의 수분분포 파악이 필수적이며 이를 통해 해당 구역에 적정하게 수분이 유지되도록 한다. 이를 위하여 매립지내부 수분분포 파악을 위하여 전기비저항탐사를 실시하였다. 본 연구에서는 수도권매립지 제2매립장 내에 침출수 재순환과 함께 장기간 전기비저항탐사를 수행하였다. 그 결과, 전기비저항값이 계절적 온도 변화에 큰 영향을 받고 있는 것을 확인할 수 있었다. 이에 따라 본 연구를 통해 조사된 온도와 전기비저항값의 상관관계를 통한 보정방법을 이용하여 바이오리액터형 매립지를 안정적으로 운영할 수 있도록 하였다.
