초록
금속이 처리된 다층 활성탄을 사용하여 축산 분뇨처리에 관한 연구를 벤치스케일로 수행하였다. Ag+, Cu2+, Na+, K+ 및 Mn2+과 같은 금속이온을 포함하는 수용액에서 처리한 활성탄 시료들의 물리화학적 특성으로써 흡착등온곡선의 형태, 미세동공과 중간동공을 가진 동공 크기분포 등을 연구하였으며, SEM, 그리고 EDX를 통한 표면구조 및 성분분석을 진행하였다. COD, BOD, T-N과 T-P의 제거에 대한 연속적인 촉매효과를 연구하기 위하여, 다층 금속처리 활성탄에 접촉시켜 걸러내었다. 다층 금속활성탄 층을 사용하여 얻어진 오염물질 제거효율이 환경부에서 제시된 기준치 이하의 만족한 결과가 나타났다. 본 연구에서 다층 금속처리된 활성탄의 효율은 유기오염물질의 흡착 및 트랩핑, 촉매적 효과의 결과로서 결정하였다.
The treatment of piggery wastes was carried out, at bench scale, using a multilayered metal-activated carbon system followed by carbon bed filtration. The physicochemical properties were obtained from treated samples with aqueous solutions containing metallic ions: Ag+, Cu2+, Na+, K+ and Mn2+. Isotherm shape and pore distribution with micro and mesopore were examined, and scanning electron microscopy and energy dispersive X-ray were used to inspect the surface structure and composition. Multilayered metal-activated carbons were used for the waste water to investigate the simultaneous catalytic effect on the COD, BOD, T-N, and T-P removal. The results showed a satisfactory removal performance that met the standard of Ministry of Environment of Korea was obtained. Efficiency of the multilayered metal-activated carbon bed was determined by the performance of material for trapping, catalytic effect and adsorption of organic solid particles.
