基于SBR反应器的ANAMMOX工艺的启动运行

采用SBR反应器,接种好氧硝化污泥,在142 d内于较高负荷下成功启动了厌氧氨氧化反应器.反应器总氮容积负荷(以N计)为0.43 kg/m3·d,总氮去除率最高达到93.3%,平均为80.5%;氨氮和亚硝酸盐氮的去除率最高达到93.9%和99.8%,平均去除率为81.2%和85.7%.在稳定运行阶段,氨氮去除量、亚硝酸盐氮去除量、硝酸盐氮生成量三者之间的比值为1:1.38:0.18.反应器启动过程中,出水、进水pH差值的变化趋势由负到正,然后稳定在一定范围内;且污泥性状有较大变化,污泥中微生物所占比率有所提高,整个反应器中适应厌氧氨氧化运行方式的菌种增殖较快.
