Abstract
The feasibility of simultaneous phosphorus and nitrogen removal by enhancing anoxic phosphorus uptake was investigated in a sequencing batch reactor (SBR). By introducing an anoxic phase into an anaerobic-aerobic SBR (AO SBR), significant amounts of denitrifying phosphorus accumulating organisms (DPAOs) which can utilize nitrate as electron acceptor could be accumulated in the reactor (anaerobic-aerobic- anoxic-aerobic SBR,
무산소 조건에서의 인섭취를 이용한 질소, 인 화합물의 동시 제거 가능성을 연속회분식반응기(SBR)를 사용하여 고찰하였다. 혐기-호기상의 AO SBR 반응기에 점차적으로 무산소상을 도입함으로써 질산염을 전자수용체로 사용하여 탈질이 가능한 인섭취 미생물들(DPAOs)을 다량으로 축적하였다.(혐기-호기-무산소-호기상의
