Abstract
The purpose of this investigation was to evaluate removal efficiency of NH4-N using the soil column. Soil, oyster shell and natural zeolite were used as a supporting media of soil column. Removal efficiencies of NH4-N were 35.9%, 41% and 93.4% for the soil column packed with soil, natural zeolite(20%) and oyster shell (20%) at HRT of 72 hours, respectively. The addition of 20% oyster shell to the soil accelerated nitrification in soil column. The influent ammonia nitrogen was mostly converted to nitrate nitrogen in the soil column and little ammonia nitrogen was found in the effluent. When the influent NH4-N concentration was 200 mg/l, the NH4-N removal was decreased at HRT of 48 hours, while nitrification was significantly increased after mechanical aeration. It was suggested that nitrification from higher NH4-N concentration was more affected by aeration in soil column process. The number of nitrifiers was approximately in a level of about 106 MPN/g soil in the soil column mixed with oyster shell (20%).
