| 摘 要： | 着重分析了在以SBR方式启动的活性污泥自培养过程周期内的氨氮、亚硝酸盐、硝酸盐、SCOD、pH、DO的变化规律。结果表明,在供氧充足的条件下,出现亚硝酸盐的积累是正常的,也是短暂的;不影响培养过程中对污泥量增长的需要,在周期性进出水过程中,COD的去除率达到80%,氨氮的去除率达到100%。通过对这些指标的分析,对于缩短曝气时间,加速反应器的启动有极大的帮助。 |

| Abstract: | This paper conducts analysis on the change rule of ammonium,nitrite,nitrate,SCOD,pH and DO in the cultivation of activated sludge by SBR process.The results show that in the condition of enough oxygen supply the accumulation of nitrite is normal and momently and it doesn't affect the sludge increase in the cultivation;in the course,the removal rate of COD and ammonium can reach 80% and 100% respectively.Analysis on these parameters can help to shorten the aeration time and speed up the set-up of reactor. |
