Abstract

Pollution reduction and/or control technology becomes one of the pressing post-semiconductor research field to lead an advanced industrial structure. Soil/groundwater remediation techniques may act as a core technology which will create many demands on pollution reduction areas. A plenty numbers of abandoned metal mines were left without any remediation action in Korea, and it may be potential sources of heavy metal and As contamination in the ecosystem. In order to bring this soil contamination to a settlement, the emerging soil/groundwater remediation techniques should be introduced. Main research topics in the United States and Europe move towards the clean remediation technology without any secondary impact and the feasible application of developing technique into the field scale study. With these advantages, several soil/groundwater techniques such as electrokinetic soil processing, permeable reactive barrier, stabilization/solidification, biosorption, soil flushing with biosurfactant, bioleaching and phytoremediation will be summarized in this paper.

환경오염저감 및 제어기술은 환경/방재 기술분야로 포스트 반도체 주력산업의 고도화분야에 해당되며, 그 중 오염토양 및 지하수 복원기술은 앞으로 많은 수요가 예상되는 핵심기술이라 할 것이다. 국내의 경우 폐금속광산이 다수 존재하며 이로 인한 중금속 및 비소오염문제가 심각해지고 있는 시점에서 이를 복원하기 위한 최신기술의 동향을 알아보는 것이 필요할 것이다. 현재 이 분야의 선진국인 미국 및 유럽각국에서의 기술개발은 2차적인 오염을 유발하지 않을 청정기술의 개발과 개발기술의 현장적용에 초점이 맞추어 지고 있는 추세이다. 여기에 최근에 개발되어진 신기술중에 이러한 장점으로 인해 주목받고 있는 기술인 전기동력학 기술, 투수성 반응벽체기술, 고형화/안정화기술, 박테리아를 이용한 생체흡착기술, 박테리아를 이용한 용출기술, 식물정화기술을 소개하고자 한다.
