정수슬러지를 탄화 및 활성처리하여 흡착제를 제조하였으며, 이를 이용한 황화수소 흡착특성을 고찰하였다. 제조 된 흡착제에 대한 BET측정 및 SEM 등 물성분석을 실시하였으며, 황화수소를 대상으로 회분식의 흡착평형실험 을 실시하였다. 실험변수로는 활성처리시 적용되는 약품종류 및 농도 등이 적용되었다. 실험결과, 정수슬러지는 탄화나 약품첨착과정을 통해 커다란 성능 향상이 이뤄짐을 알 수 있었다.
H2S adsorption characteristics of adsorbent made by drinking water treatment sludge were investigated. For analyses of the manufactured adsorbent, various methods such as scanning electron microscope(SEM), measurements of BET surface area and pore volume were adopted. As major adsorption characteristics, adsorption equilibrium capacity was measured using a batch type experimental apparatus for operating variables such as chemical reagent types and concentrations. The experimental result showed that the H2S adsorption equilibrium capacity of adsorbent made by drinking water treatment sludge much more increases with an impregnation of chemical reagents and carbonization for the sludge.
