 Abstract
In this study, the removal characteristics of organic components and nutrients of sewage taken from the Suwon area were investigated in a lab-scale modified DNR (Daewoo Nutrient Removal) process. The modified DNR process consisted of a sludge denitrification tank, an anaerobic tank, an anoxic tank, an aerobic tank, a secondary anoxic tank and a secondary aerobic tank. The proposed process with the average C/N ratio of 3.5 was performed for the sewage treatment. The results were compared with other existing DNR processes. The organic fractions in sewage were analyzed by measuring the oxygen uptake rate. The resulting removal efficiencies of SS, BOD, COD, TN and TP were 93.1%, 95.5%, 86.1%, 67.8% and 80.6%, respectively.
