A novel rotating drum biological contactor (RDBC) was operated with MBBR packing particles inside, by which anaerobic, anoxic and aerobic operating modes can be achieved by adjusting immersion level or rotating speed. The volume oxygen transfer coefficient (KLa) and power efficiency can reach 25.87 h?1 and 228.62 g·(kW·h)?1, respectively. Synthetic domestic sewage was treated with step feed post-denitrification process. The results showed that the optimal operating conditions were immersion level 2/3, rotating speed 8 r·min?1 and DO 3.0 mg·L?1 in aerobic tank, and immersion level 5/6, rotating speed 8 r·min?1 and DO 1.0 mg·L?1 in anoxic tank. In above conditions, when the influent average COD was 385.0 mg·L?1, 4NH+-N 38.0 mg·L?1, TN 38.0 mg·L?1, total inflow 6 L·h?1 (HRT=18 h) and flow distribution ratio 3:1, the remove rate of effluent COD, 4NH+-N and TN can reach 90.4%, 93.7% and 80.9%, respectively, which can meet the first level A discharge standards in China (GB18918—2002).
