| Abstract |
A fixed-film biological reactor(FFBR) packed with SAC(Synthetic Activated Ceramic) media was tested to investigate the removal efficiency of both organic matter and ammonia of raw sewage and final effluent of J municipal wastewater treatment plant in Pusan. The influent to the wastewater treatment plant of the city of Pusan consists of typical municipal wastewater and the discharges of industrial works and sanitary landfill leachate. Experiments were performed to evaluate the removal efficiencies of chemical oxygen demand(COD_(Cr)) and ammonia in two lab-scale FFBR by increasing COD_(Cr), loading rate from 0.85㎏/㎥/day to 1.24㎏/㎥/day and NH₄^+-N loading rate from 0.24㎏/㎥/day to 0.48㎏/㎥/day in case that raw sewage were used as substrate. In case of final effluent as substrate, the FFBR demonstrated of achieving 28.3∼33.4% removal efficiencies of COD_(Cr) at the COD_(Cr) loading rates of 0.28∼0.55㎏/㎥/day and 67.0∼85.3% removal efficiencies of NH₄^+-N at the NH₄^+-N loading rates of 0.13∼0.38㎏/㎥/day. The results of the research showed that a fixed-film biological reactor(FFBR) packed with SAC media could be applicable for treatment of raw sewage and final effluent since the process is, compared to the conventional activated sludge process, more effective at the sewage including high NH₄^+-N loading rates. |
