배치 실험을 이용한 암모니아 제거 기작 및 효율 평가 = Evaluation of Ammonia Removal Mechanisms and Efficiencies Through Batch Experiments

다국어 초록 (Multilingual Abstract)

As the amount of livestock wastewater increases, ammonia contamination in surface water and groundwater is alsoincreasing, and its treatment is urgently needed. In this study, indigenous soil bacteria was utilized for ammonia removal inartificial wastewater and associated removal mechanisms and efficiencies were evaluated. Two batch reactors wereconfigurated to contain natural soil and artificial wastewater at 1:10 mass ratio, and incubated for 84 and 168 hours,respectively. The results showed that ammonia was completely removed within 48 and 72 hours in the first and secondreactors, respectively. There were no significant changes in ammonia concentrations in the control groups without soil.
Nitrate was formed in the reactors, indicating that the main removal mechanism of ammonia was nitrification by nitrifyingbacteria. Nitrate was further converted to nitrogen gas by denitrification in the anaerobic environment, which was causedby consumption of oxygen during the nitrification process.
