Abstract

A pilot scale sequencing batch biofilm reactor (SBBR) for treating wastewater was used for the purpose of investigating treatment performance under different aeration flows(10m3/h 12m3/h 14m3/h 16m3/h 18m3/h 20m3/h 22m3/h 24m3/h),by analyzing the changeable concentra-tion of COD NH4+-N NH3--N NH2--N and TN both influent and effluent. To find the optimum condition of aeration, provide a reference for practical engineering application. The experimental results showed that, the amount of aeration have less effect on COD removal efficiency but on ni-trogen removal. The SBBR could achieve a higher degree of SND, and TN removal could maintain around 62% , the quality of effluent meet level 1B standard of Discharge standard of pollutants for municipal wastewater treatment plant When the aeration flow was controlled the range of 16~18mg/L.
