Abstract

The effect s of aeration time on the treatment of brewery wastewater in SBR reactor were investigated by using synthetic brewery wastewater. The experimental result indicates that under the condition of influent COD is 300～650mg/L, the temperature is 25°C, continual aerations is 2.5 h and sludge density is 2000～3000 mg/L, the reactor has a good degeneration ability of COD and NH4+-N in simulation brewery wastewater，removal rate can reached 90 % or more，phosphate removal efficiency was above 70%. so the SBR technology is feasible．
