영문 초록

This study was carried out to investigate the performance of individual sewage treatment facilities with MBR(membrane bioreactor). After ratio of influent distribution of aerobic reactor to anoxic reactor from 4 : 6 to 7 : 3, the effluent quality is improved 5.3 mg/L as BOD, 3.8 mg/L as SS, 5.6 mg/L as T-N, and 1.6 mg/L as T-P, respectively. The removal efficiency rate of effluent increased upto 98% as BOD, 99% as SS 94%, as T-N as 93% and T-P, respectively. To maintain SS concentration of the effluent less than 1 mg/L, the washing and differential pressure of membrane management were required, the wasted activated sludge periodically discard to the sludge storage tank in order to meet standard criteria. The capacity of this individual facilities was overestimated, when low loading occur, an alternative is considered.
