본 연구는 활성슬러지공법을 변형시킨 무산소일염기일호기반응조를 사용해서 질산화일탈질소반응 및 인의 방출인초과축적반응을 유도하여 합성페수의 유기물, 질소 및 인을 동시에 제거하였다. 무질소조, 무염기 및 호기호 각각에 대한 반응특성을 조사하기 위해 실험실규모의 반응조가 운영되었으며 MLSS농도를 5000, 4200, 3300, 2600, 1900mg/l로, 변화시켜 COD제거율에 대한 생물학적 동력학계수를 결정하였다. 연구결과, 유기물 및 영양염이 변형된 슬러지공법에 의해 동시에 제거될 수 있음을 알았고, ortho-p 제거효율은 66%∼99%로 높게 나타났다.

This study deals with the performance of an acivated sludge system which is modified by the researcher to function without any additional chemical or internal recyle in removing organics, nitrogen, and phosphorus from synthetic wastewater. To improve the nutrient removal efficiency, the researcher utilized the anoxic, anaerobic, and aerobic reactor sequences with a single sludge return, whiched to nitrification/denitrification and phosphorus release/overplus accumulation. A bench scale system was operated with a view to investigating the reaction characteristics of each reactor, and to measuring the biological kinetic coefficients(Y, $K_d$, k, $K_s$) for theremoval of COD in relation to the mean cell residence time at five different MLSS concentrations, 5000, 4200, 3300, 2600, and 1900 mg/l. The results of the research showed that organic substance and nutrient were removed simultaneously by this modified activated sludge process. And the process kad 66%-99% ortho-p removal efficiency.
