Abstract

In this study, a selecvively block barrier was developed to prevent the spread of contaminants (TPH, Phenol) in the ground only when contamination occurs. The materials were used Jumunjin sand, bentonite, polyolefin elastomer and spill hound marine. First, the properties and environmental hazards characteristics of materials were analyzed for evaluated their usability. Then, the possibility of use as a barrier material was confirmed by analyzing the water permeability characteristics that change after 24 hours of contact with contaminants. As a result of the analysis, the pH of each component was similar to the general groundwater pH range. In addition, the toxicity characteristics and the possibility of dissolution of hazardous substances, it was determined that there was no environmental hazard as the content was below the regulation value. Lastly, when comparing the permeability coefficient before and after contact with the contaminant, the permeability coefficient of approximately α × 10-3cm/sec before contact was reduced to α × 10-6cm/sec after contact with the contaminant.

본 연구에서는 지중 내 오염물질(TPH, Phenol)의 확산 방지를 위해 오염 발생시에만 선택적으로 차수성능을 발현하는 차수재를 제조하고자 하였다. 선택적차수재의 구성물질로는 주문진규사, 벤토나이트, 폴리올레핀 엘라스토머, 스필하운드 마린을 사용하였으며, 본 연구에서는 구성물질들의 활용가능성을 평가하기 위해 기초 특성 및 환경유해성을 확인하였으며 오염물질과의 접촉 24시간 후 변화되는 투수특성을 비교하여 차수재로서 사용가능성을 확인하였다. 각 구성물질의 pH는 일반 지하수 pH 범위와 유사하였으며 독성특성 및 유해물질 용출가능성 분석결과 기준치 이하의 함량을 보여 환경유해성은 없다고 판단되었다. 또한 오염물질 접촉 전‧후 투수계수를 비교하였을 때, 접촉 전 α × 10-3cm/sec 내외의 투수계수가 오염물질과 접촉 이후 α × 10-6cm/sec로 감소된 결과를 보여 차수재의 비오염 상황에서는 투수성과 오염발생시 차수성능 발현을 확인할 수 있었다.
