Claims (7)
- 진공배수 기법과 동전기 현상을 복합시킨 진공-동전기 배수정화 기법은 중금속으로 오염된 고함수비의 하상 퇴적토와 광미를 빠른 시간 내에 정화 및 탈수 처리하는 방법으로 양극(+)에서 전기분해에 의해 발생하는 H+이온이 정전기적 인력에 의한 전기이온이동과 전기삼투, 진공배수에 의한 이류 등으로 시료 내에 유입되어 토립자 표면에 흡착된 중금속을 탈착시키고, 탈착된 중금속 이온들을 정전기 인력에 의한 전기이온이동과 전기삼투, 진공배수에 의한 이류로 음극(-)겸용 배수재로 중금속을 제거하는 동시에 진공배수와 전기삼투로 간극수를 원활하게 배수하여 탈수를 촉진하는 것이다.
- 제 1항에 있어서,본 공법을 적용하기 위한 전극과 배수재를 결합한 전극(-)겸용 배수재와 연결 클램프의 개발.
- 제 1항에 있어서,현장의 시간차 매립을 고려하여 라군(lagoon)이나 폰드(pond)에서 전극의 층별 교차로 다단계 투기를 수행하여 적용성을 높이는 방법.
- 제 1항에 있어서,하상 퇴적토와 광미를 라군(lagoon)이나 폰드(pond)에서 처리하는 것 외에 매립지의 현장 매립재료로 사용할 때, 현장에서 본 공법을 직접 적용하는 방법.
- 제 1항에 있어서,음극(-)겸용 배수재에서 진공압에 의해 전기분해에 의해 발생하는 OH-이온의 시료 내 유입을 억제하여 수산화 침전을 방지하는 방법.
- 제 1항에 있어서슬러리 조건별 최적의 진공압과 전압을 조합하여 적용하는 방법.
- 유기 오염물에 대한 정화 처리를 위해 기존의 유기 오염물에 관한 처리 공법과 본 공법을 결합하는 방법.
