摘要
本研究通过水力停留时间、泥龄和周期运行跟踪研究确定系统处理效果和稳定性。水力停留时间试验表明13h的停留时间下TP、COD、NH4+-N,TN的去除率都在86%以上。研究还表明五箱一体化活性污泥工艺能在交替运行过程中实现高效除磷脱氮。
This study is to ascertain treating efficiency and stability of this system by THRT, SRT and cyclic operation control. Test on HRT indicated that the removal rate of TP, COD, NH^4＋-N and TN could reached to over 86% at 13h HRT. The results also showed that the five-tank integrated active sludge process could realize dephosphorization and denitrification at high efficiency.
