Abstract

The effects of Sequencing Batch Biofilm Reactor with polyurethane foam as microorganisms immobilized suspended carriers was tested under the optimal operation conditions, with aerobic, anaerobic, anoxic mode, texted and analysis the effluent indicators of TN, TP, NH4+-N, COD under the optimal conditions acerbic process, 2hr for aerobic process, 1hr for anoxic process, 10min for clarification, 5min for discharging, 10min for clarification, 5min for discharging and 200min for standby. The result showed that the average removal rates for TN, TP, NH4+-N& COD was about 93%, 91%, 97%, 95% respectively under the optimal operation conditions, the effluent concentration of TN, NH4+-N& COD met the first level A Criteria Specified in Discharge Standard of pollutants for Municipal Waster Water Treatment Plant(GB18918-2002), TP closed to the first level A criteria.
