얕은 불포화 및 포화 대수층을 모사한 SAT 토양칼럼에서의 하수처리장 방류수 처리 수질 변화 = Water Quality Changes in Wastewater Effluent from the Unsaturated and Saturated Soil Aquifer Treatment(SAT) Columns Simulating Shallow Aquifer

다국어 초록 (Multilingual Abstract)

Water quality changes of wastewater effluent in the shallow aquifier condition was investigated using laboratory unsaturated and saturated SAT columns for over five months. Average DOC removal was 31.9% in the unsaturated SAT column whereas no removal occurred in the saturated SAT column. Under the shallow aquifer condition, nitrification was not completed in the unsaturated SAT column, releasing residual ammonium nitrogen into the saturated SAT column. Short retention time (one day) in the shallow unsaturated SAT column rendered DO of about 2 mg/L to the influent of the saturated SAT column. Phosphate was not removed at all in the unsaturated SAT column while complete removal was achieved in the saturated column. Consequently, organic and inorganic compounds were removed under the shallow aquifer condition as effectively as was in deep aquifer, except for the release of ammonium and relatively high DO into the saturated SAT column.
