Abstract

In Incheon area, 1960s of economic development planning and heavy industry center of efforts industrial park and port facilities, It is industrial land reclamation by coastal landfill, these industrial park has the characteristics of Low permeability lipid is embedded in the silty sand that was dredged. In this study, To evaluate the heavy metal adsorption ability to filter of drains that have been developed as environmentally friendly materials by applying the effective zeolite to heavy metal adsorption for soil pollution purification suitable for geological characteristics of Incheon. soil pollution Survey data and Literature search, which is the current through the industry, the most problematic was set to Cadmium (Cd) and Copper(Cu), Lead (Pb). and Using the Numerical Analysis using the Visual Modflow, was presented the most efficient drains set interval and format.

인천지역은 1960년대 경제개발계획과 함께 중공업위주의 임해공업단지와 항만시설, 해안매립에 의한 공업용지가 조성되었고, 이러한 산업단지는 준설한 실트질 모래로 매립되어 저투수성 지질특성을 가지고 있다. 따라서, 본 연구에서는 인천의 지질특성에 적합한 토양오염 정화를 위해 친환경 소재로 개발된 배수재의 필터에 중금속 흡착에 효과적인 제올라이트를 도포하여 중금속흡착능력을 평가하였다. 오염물질은 토양오염 조사 자료와 문헌 조사를 통해 현재 공업 산업단지에서 가장 문제가 되고 있는 구리(Cu), 납(Pb), 카드뮴(Cd)으로 설정하였고, Visual Modflow를 이용한 수치해석을 통해 가장 효율적인 배수재 타설 간격 및 형식을 제시하였다.
