| 摘 要： | 利用Eckenfelder公式得出了MBR系统中不同污泥停留时间底物降解速率和氨氮的去除速率,结果表明在对数增长阶段和减数增长阶段,SRT为17 d时,对有机底物的降解速率和氨氮的去除速率都高于SRT为8、27、37和42 d的污泥系统对两者的去除,说明SRT对MBR污泥系统的活性有较大影响,确定排泥时间应综合考虑污泥活性、污泥产量和膜通量等因素.

| Abstract: | The removal rates of COD and NH+4-N were gained at different SRTs by Eckenfelder equation. The results indicated that the removal rates of COD and NH+4-N at SRT=17 d were higher than that at SRT=8 d,27 d, 37 d and 42 d in both log and declining growth stages. Accordingly, it suggested that SRT had a significant effect on the sludge activity of the MBR system, and the sludge activity, yield and permeate flux of membrane should be taken into account while determining the SRT of membrane bioreactor |
