| 摘 要： | 目的 解决对短程硝化过程影响因素pH值研究不充分及短程硝化过程中氮的缺失的问题.方法 在SBR反应器中用传统活性污泥作为种泥驯化污泥,以模拟生活污水为处理对象进行动态实验,考察pH值对系统短程硝化反硝化的影响及系统运行周期内总氮缺失原因.结果 pH＝8.5,6 h的氨氮转化速率为8.9 mg/(L·h),亚硝态氮积累率高达93%;亚硝酸盐氮积累率随反应时间逐渐降低,pH越低,下降越多,pH＝7.1时,从2 h的80%下降到6 h的75%;进水pH值越高,反硝化2 h时总氮的去除效率越高,pH＝8.5时,系统总氮的降解速率达到5.6 mg/(L·h);短程硝化过程中存在氮的缺失现象.结论 进水pH越高,氨氮降解速率、亚硝态氮积累率和总氮去除率越高,系统周期中氮的缺失主要是同步硝化反硝化作用的结果.
