수피를 이용한 투수성반응벽체의 적용성평가 = The Application of Permeable Reactive Barrier Using Barks

다국어 초록 (Multilingual Abstract)

The contaminated water of abandoned mine flows to river going through ground water. It has much quantity of heavy metals that discharges without water treatment plants. It is going to flow into the river and water quality is getting worse. Furthermore, that flows to river while contaminate soil. So, it causes problems for the environment and society. However, it is difficult for water treatment plants to emplace each position because it has many problems on the ground of economic, security of site and so on. In order to find a solution these problems, we chose PRB(Permeable Reactive Barriers). The goal of this study is eco-friendly technical development reusing waste resources. In this research, three reacting media were used. The first reacting medium is ZVI(Zero-Valent Iron). It is known as great heavy metal remover. The second reaction medium is steel-making slag. It is suitable medium to remove heavy metals, because its components are lime and iron oxide. Finally, reacting medium is bark. The bark is an epidermis of tree that is dead tissue of tree trunks and branches in the outermost. Its chemical structure is carboxyl and hydroxyl that are well combined with heavy metals. After pilot of PRB, be experimented with artificial contaminated water. The arsenic, cadmium, and lead were put into the artificial contaminated water
