| 摘 要： | 为了达到同步脱氮除磷的目的,采用SBR反应器处理模拟生活污水,在厌氧/好氧/缺氧(AOA)的运行方式下,研究了曝气量对系统脱氮除磷效果的影响。试验结果表明,当曝气量为28L/h时,系统对氮、磷及COD的去除效果均较佳;为避免发生二次释磷,应使缺氧段末期的NO3--N浓度>2.5mg/L;系统对NH4+-N的冲击负荷有很好的抵抗能力;采用pH、ORP对系统进行实时控制,可获得较好的脱氮效果,并降低了能耗。

| Abstract: | In order to realize simultaneous nitrogen and phosphorus removal,the sequencing batch reactor(SBR)was used to treat simulated domestic sewage.The effect of aeration rate on nitrogen and phosphorus removal was studied under the anaerobic,aerobic and anoxic modes.The results show that when the aeration rate is 28 L/h,the better removal effect of nitrogen,phosphorus and COD can be obtained.At the end of the anoxic stage,nitrate concentration should be more than 2.5 mg/L,otherwise the secondary phosphorus relea... |
