- Abstract:以普通活性污泥为种泥,控制COD/N为2,通过逐步提升NO 2 - -N浓度(由15上升至200mg/L)的方式在小试SBR反应器中实现了短程反硝化的启动;稳定运行期间,NO 2 - -N的平均去除率达99.5%.在此基础上,通过批式试验考察了不同进水pH值(7.1、8.2和9.3)对短程反硝化及N 2 O释放特性的影响.结果表明,随着进水pH值的升高,平均反硝化速率由0.087 9上升至0.094 1和0.107 2 mg/(min·gSS);反硝化效率先降后升,分别为98.70、96.52和99.10%;而N 2 O的释放量随pH值升高呈降低的趋势,pH值为7.1时的释放量分别是8.2和9.3时的2.82和8.04倍.因此,适当提升进水pH值可大幅降低短程反硝化过程N 2 O的释放量.
