This study was conducted to evaluate the removal efficiencies of organic matter and pharmaceuticals and to identify the removal mechanism of pharmaceuticals using sand obtained from Hwangryong River in Jangsung. Batch and column studies were used to simulate managed aquifer recharge (MAR) systems. All experiments were performed using field effluent containing pharmaceuticals from Damyang Wastewater Treatment Plant as an influent. Based on the removal results of organic matter and pharmaceuticals from the batch and column experiments, soil organic matter (SOM) and microbial activity were found to effectively remove target contaminants. The removal of organic matter was found to increase under biotic conditions. Neutral and cation pharmaceuticals (iopromide, estrone, and trimethoprim) exhibited removal efficiencies higher than 70% from natural sand and baked sand media in batch and column studies. Carbamazepine persisted in the sand batch and column studies. Anion pharmaceuticals (ketoprofen, ibuprofen, and diclofenac) can be removed under conditions featuring high SOM and adenosine triphosphate (ATP) concentrations in the sand surface. Based on the experimental Batch and column results, biodegradation and sorption were found to be important mechanisms for the removal of pharmaceuticals within the simulated MAR systems.
본 연구에서는 장성에 위치한 황룡강에서 채취한 모래를 이용하여 유기물질과 의약화합물 제거효율을 평가하고 의약화합물의 제거 메커니즘을 규명하고자 하였다. 회분식 실험 및 칼럼 실험으로 대수층 함양관리기술을 모사하였으며, 모든 실험은 담양 하수처리장의 의약화합물이 포함된 최종방류수를 원수로 하여 구동하였다. 회분식 실험 및 칼럼 실험을 통해 유기물질과 의약화합물은 토양 유기물질과 미생물 활성도에 영향을 받아 제거되는 것을 보였다. 유기물질 제거는 생물학적 조건에서 잘 되는 것으로 나타났다. 중성과 양이온 의약화합물(iopromide, estrone 및 trimethoprim)의 경우에는 일반 모래, 구운 모래를 사용한 회분식 실험 모두 70% 이상의 제거효율을 나타냈다. 반면, carbamazepine의 경우는 회분식과 칼럼 실험에서 제거가 잘 이루어지지 않았다. 음이온 의약화합물 (ketoprofen, ibufrofen 및 diclofenac)의 경우 모래 표면의 SOM과 미생물 활성도에 영향을 받아 제거가 되는 것을 보였다. 회분식과 칼럼 실험을 바탕으로 생물학적 영향과 수착이 대수층 함양관리기술에서 의약화합물 제거에 주요한 메커니즘으로 나타났다.
