Claims (6)

  1. 초기도입된 과산화수소의 24시간 평균 농도가 0.0001% 내지 0.1%이고, 시간이 경과함에 따라 지하층 내의 생물군에 독성 환경을 제공하지 않으면서 생물군에 유용한 산소를 상응하게 증가시키기에 충분한 비율로 과산화수소의 24시간 평균 농도를 증가시킨 후, 단시간 동안 도입부위 또는 이의 바로 인접부위에서 생물군에 충분히 독성이 되도록 지하층에 도입된 과산화수소 농도를 간헐적으로 증가시킴으로써 생물군을 제거하고 과산화수소 도입부위 또는 이의 인접부위에서 지하층의 투과성을 증가시키도록, 과산화수소 수용액을 지하층의 최소한 한 부위에 도입시킴을 특징으로 하여, 지하층 내의 화합물의 생물적 산화를 자극하기 위해서 산소 및 영양소를 생물군에 효과적으로 공급하고, 경우에 따라 상기 과산화수소 수용액이 유동조절제를 함유하고, 지하층이 인산염 용액 및 필요시 유리산소 가스 형성을 방지하는 양의 과산화수소용 분해제로 처리되는 방법.
  2. 제1항에 있어서, 수용액중 과산화수소 농도의 단시간 증가가 약0.5 내지 약3중량%인 방법.
  3. 제1항에 있어서, 수용액중 과산화수소 농도의 단시간 증가가 약 0.5 내지 약3중량%이고, 상기 수용액이 pH를 3이하로 저하시키는 산을 추가로 포함하는 방법.
  4. 제1 내지 3항중 어느 하나에 있어서, 지하층에 도입되는 과산화수소용 분해촉매를, 수용액의 오염물 부근에로의 분포를 차단시킬 수 있는 유리 산소가스의 형성을 방지하기 위해서 과산화수소의 분해를 조절하는 데 충분한 양으로 하여, 효소, 전이금속이온 및 전이금속 이온의 킬레이트중에서 선택하여 포함시킴을 특징으로 하는 방법.
  5. 제1 내지 4항중 어느 하나에 있어서, 과산화수소 수용액이 지하층내 과산화수소 수용액의 흐름을 조절하기에 충분한 유효량의, 수화성 중합물질, 계면 개질제, 및 조밀제중에서 선택된 유동조절제를 포함함을 특징으로 하는 방법.
  6. 제1 내지 5항중 어느 하나에 있어서, 인산염용액을 도입시켜 지하층을 예비처리하는 단계를 포함하는 방법.
