영문 초록

This study was accomplished to estimate the biodegradability of sewage using RBC(Rotating Biological contactors) and to get a basic data for design parameters. RBC systems were applied to laboratory scale reactors with varying HRT feeding sewage as of about BOD 70 mg/l. 80 mg/l and 120mg/l, respectively. According to the continuous operation, it showed that RBC w/ recycling was similar to RBC w/o recycling in organic removal efficiency or TP removal efficiency, but neither system effectively removed TN. To get the above 90% of BOD removal efficiency, both were recommended to design as BOD organic loading rate was less than about 4.5 to 6.0 g/㎡/d, hydraulic loading was less than about 80ℓ/㎡/d. It showed that RBC w/ recycling was inferior to RBC w/o recycling in TN removal efficiency. At the 5.0g/㎡/d, TN removal efficiency of RBC w/ recycling and RBC w/o recycling was about 50%, 70%, respectively. SNR(Specific Nitrification Rate) was tending to increase as shorter HRT. SNR of RBC w/ recycling and RBC w/o recycling was 0.4 mgNH ₄⁺-N/gMv/hr, 0.7 to 1.0 mgNH₄⁺-N/gMv/hr, respectively.
