The purpose of this paper is to investigate purification characteristic of soil-bentonite landfill liner and to develop of desirable liner system. In this study, column tests for soil-bentonite, reactive soil-bentonite and existing bentomat and reactive bentomat were carried out under the high pressure with water and leachate.

본 연구는 혼합차수재와 개발차수시스템의 정화특성을 연구하기 위한 것이다. 정화특성을 분석하기 위하여 혼합차수재, 혼합반응차수재 및 반응벤토매트가 적용된 시스템에 일반수와 침출수를 이용하여 높은 압력하에서 컬럼식 용출시험을 수행하였다. 실험결과 암모니아성 질소(NH₃-N) 및 중금속인 납(Pb), 구리(Cu) 등의 많은 양이 혼합반응차수시스템에 의해 효과적으로 제거됨을 알 수 있었다.

The purpose of this paper is to investigate permeability characteristic of soil-bentonite landfill liner and development of desirable liner system. In this study, permeability tests for soil-bentonite, reactive soil-bentonite and apply bentomat and reactive mat are carried out under the low and high water pressure. According to test result, additional amount of bentonite decreases the coefficient of permeability up to the bentonite mixture ratio of 15%. Therefore, the permeability test for landfill liner's indicated that the use of general water would be in more safe side because the liner system show low permeability duet decrease effect of porous by suspended soild(SS). The permeability of leachate for Zeolite mixture ratio 0, 5, 10% with bentonite mixture ratio 15% showed negligible variation in the permeability with general water. Therefore, Zeolite could be used as a successful that is available purification material for the treatment of leachate, without changing the of landfill liners. Also odious smell could be removed by adding smell amount of Zeolite to the leachate. It was revealed that the bentomat and reactive mat installed in soil-bentonite layer effectively improved the permeability as well as purification of the leachate.
