dc.description.abstract | 소규모 하수처리시스템에 다양한 반송비와 고정식 담체를 적용하여 합성폐수에서 질소, 인의 제거를 검토하였다. 담체를 첨가 시 질소의 제거율은 40.1%에서 65.1%로 증가하였으나 COD와 인의 제거에는 영향이 없었다(<5%). 반송을 통해 유량을 2배(2Q)로 증가시킨 경우 질소의 제거율은 7% 정도가 증가하였으나, 인 제거율은 반송비가 증가됨에 따라 31.8에서 26.6%로 감소하였다. 무산소조에서 담체에 부착된 미생물은 약 73.4 mg/cm2로 존재하였으며, FISH분석 결과 탈질 미생물인 Pseudomonas aeruginosa 존재 (약 58%)를 확인하였다.The effect of recycling ratio and fixed media on nitrate and phosphate removal was investigated in a pilot-scale wastewater treatment unit using synthetic wastewater. Addition of fixed media increased nitrate removal from 45 to 58% while no noticeable change was observed for Chemical Oxygen Demand (COD) and phosphate removal (&lt;5%). Nitrate removal efficiency also enhanced (Ca 7%) when the influent wastewater flow was doubled (2Q), however phosphate removal was decreased from 40.9 to 26.6% with the increasing recycling rate. The attached biomass analysis showed the presence of bacteria (73.4 mg/cm2) on the surface of added media in anoxic reactor. Pseudomonas aeruginosa a common denitrifying bacterium dominated the bacterial growth (58%) in the anoxic reactor which was determined using Fluorescence In Situ Hybridization (FISH) analysis. | en_US |
