dc.description.abstract일반적으로 유입수내 COD 분율 특성을 예측하기 위해 산소이용률(OUR; Oxygen Uptake Rate)을 이용하는데 이는 높은 F/M비를 적용하여 장시간의 모니터링을 통해 결과를 획득하므로 실시간 공정제어에는 적합하지 못하다. 본 연구에서는 이러한 단점을 극복하기 위해 20분 이내의 짧은 시간에 결과를 확인 할 수 있는 급속 OUR모니터링을 제시하였다. 먼저 실험에 적합한 최적 F/M비를 도출한 결과 0.03~0.05로 나타났으며 이를 생활하수 및 공장계유입폐수에 적용하여 급속 OUR모니터링을 실시했을 때 생활하수는 20분 이내에 OUR곡선 특성을 확인할 수 있었지만 공장계유입폐수의 경우 0.0075의 F/M비에서 만족하는 결과를 얻을 수 있었다. 또한 이분해성COD를 예측한 결과 각각 약 50%와 6%의 값을 나타내었다.-
dc.description.abstractIn this study, rapid Oxygen Uptake Rate(OUR) monitoring method was used predicting influent COD fractionation. Optimal F/M ratio range of 0.03∼0.05 was found using synthetic wastewater, which was made by glucose, to confirm variation tendency of OUR curve within 20 minutes. And then, influent Readily Biodegradable COD(RBCOD) variation characteristics were determined through microorganism respiration ratio with the calculated F/M ratio for various wastewater. In conclusion, the method using OUR for prediction of influent RBCOD could be applied for domestic wastewater similar to synthetic wastewater in appropriate time, but not for treated industrial wastewater. In addition, RBCOD of domestic wastewater and treated industrial wastewater were 50 and 6%, respectively.-
