초록

주물사의 일반적인 지하수 오염물질인 TCE에 대한 반응성을 조사하기 위해 batch와 column실험을 하였다. 본 실험에서 얻어진 주물사의 반응성은 실제 반응벽체에 쓰여지는 철에 비해 높거나 비슷한 결과를 나타내었다. 또한, 주물사에 포함된 클레이와 TOC에 의해 TCE의 이동이 급격히 감소하는 것을 관찰하였다. 따라서, 실제 현장 상황에서는 토양미생물에 의한 분해에 의해 계산된 값보다 훨씬 낮은 농도의 TCE가 검출되리라 예상된다. 실제 현장 반응벽체 설계에 있어서 1 m두께의 벽체가 설치되기 위해서는 주물사에 포함된 철의 함량이 1%이상이면 안전측으로 벽체설계가 가능하다고 볼 수 있다.

Batch and column tests were conducted with common groundwater contaminants (i.e., trichloroethylene) to determine transport parameters and reactivity of the foundry sands. The reactivities of foundry sands for common groundwater contaminants are comparable to or slightly higher than those for Peerless iron a common medium used in permeable reactive barriers. In addition, the TOC and clay in foundry sands can significantly retard the movement of target contaminants, which may result in lower effluent concentrations of contaminants due to biodegradation. In general, permeable reactive barriers with the thickness of 1m can be constructed with many foundry sands to treat typical groundwater comtaminants provided the zero-valent iron content in the foundry sand is higher than 1%.
