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 were adopted. As the major adsorption characteristic, breakthrough curve was measured by using a continuous fixed bed adsorption column for operating variables such as aspect ratio(L/D, 3∼9), gas flow rate(0.2∼1.0 liter/min) and type of samples. The experimental results showed that the breakthrough pint decreased with increasing gas flow rate, but increased with increasing aspect ratio. It was also found that the physical and chemical treatments of drinking water treatment sludge are very important for the improvement in H2S adsorption capacity due to property changes of the sludge.
