摘　　要：对无回流间歇曝气系统工况、泥龄与总磷去除率关系进行了探索, 通过单因素和双因素正交试验, 找出了工况、泥龄共同影响下的ηTP。试验表明,在曝气停曝周期T=6.0 h , 厌氧时间1.5 h, 沉淀排水时间0 .5 h 的条件下, 当SRT= 20 d , 曝气比为0.42 时,NBIAS系统的ηCODcr ,ηTN,ηTP 分别为85% ,75% ,69 % 。In this paper the phosphorus removal performance has been studied in Non-backflow Intermittent Aeration System (NBIAS), when the aeration duration and SRT were adjusted. At the same time, nitrogen removal was also studied. Test results show that when the cycle duration is 6 h., anaerobic duration 1.5h. sedimentation and displacement time 0.5 h. and SRT=20 d,aerobic ratio 0.42, the removal efficiency for CODcr, nitrogen and phosphorus will be 85%, 75% and 69%, respectively.
