Abstract

A study of physical properties and their application using K-powdered activated carbon system followed powdered carbon dispersion was carried out at laboratory. scale. Two types of K-powdered activated carbon for the dispersion have been used in this study to investigate the catalytic removal efficiency of pollutants from the wastewater. From the surface properties obtained for carbon samples treated with aqueous solutions containing potassium salts, main investigations were subjected to isotherm shape, SEM, EDX and surface functional groups. K-powdered activated carbons were dispersed to wastewater with pH variation to investigate the removal efficiency for the color, COD, T-N and T-P. From these removal results of the piggery waste using K-powdered activated carbon, satisfactory removal performance in the region of pH 6~8 was achieved. The excellent effects for the dispersion of the K-powdered activated carbon were proved by the above mentioned properties of the material for adsorption and trapping of organics, and catalytic effects.

활성탄 미분을 용액계에 분산하므로 수반 되는 결과를 고찰하기 위하여 칼륨처리 미분 활성탄의 물리적 성질과 그들에 응용에 대한 연구를 수행하였다. 오염수로부터 오염물질의 촉매적 제거 효율을 연구하기 위하여 분산매로써 두 종류의 칼륨 미분 활성탄을 사용하였다. 칼륨염을 포함하는 수용액내에서 처리된 활성탄 시료로부터 얻어진 표면 특성화를 위하여, 흡착 등온곡선 형태, SEM, EDX 및 표면 기능기 변화 등을 주된 연구 대상으로 하였다. pH 변화에 따른 칼륨 미분 활성탄을 오염수에 분산하여 색도, COD, T-N 및 T-P 등에 대하여 제거 효율을 연구하였다. 칼륨 미분 활성탄을 처리한 오염수에 대한 네 가지 요소 제거 결과로부터, pH 6~8의 범위에서 만족할 만한 제거 효율이 얻어 졌다. 본 연구로부터 칼륨 처리 미분 활성탄의 분산에 의한 오염물질의 제거 효율이 흡착 특성 및 촉매적 효율에 의하여 입증되었다.
