BACKGROUND
Simultaneous nitrogen, phosphorous and COD removal in a pilot-scale enhanced Sequencing Batch Reactor (eSBR) was investigated.
METHODS
The reactor consisted of a pre-anoxic zone and internal recycle and was fed with synthetic wastewater. The study was performed by operating the reactor in 6-hour cycles in three different operational modes during a time frame of 279 days.
RESULTS
Under the best operational conditions, the average removal rate of COD, TN, and TP were obtained as 93.52, 88.31, and 97.56%, respectively.
CONCLUSIONS
A significant denitrifying phosphorus removal (more than 80%) occurred at run1 and 3 which started the cycle under anoxic condition.
背景
在中试规模的强化序批式反应器（eSBR）中同时去除氮、磷和 COD。
方法
该反应器由预缺氧区和内部循环组成，并使用合成废水进行进料。在 279 天的时间框架内，通过在三种不同操作模式下以 6 小时的周期运行反应器来进行研究。
结果
在最佳操作条件下，COD、TN 和 TP 的平均去除率分别为 93.52%、88.31%和 97.56%。
结论
在运行 1 和 3 中发生了显著的反硝化除磷（超过 80%），这是在缺氧条件下开始循环的结果。
