摘要(Abstract)：

采用流化床填料序批式生物膜反应器(SBBR),考察了低盐度对同步硝化反硝化脱氮性能的影响。结果表明,在试验盐度范围内(0.15~1.00),提高盐度对CODCr的降解影响很小,去除率都接近90%;氨氮去除率在0.45盐度时达到最大,为90.1%,当盐度提高到0.60和1.00时,氨氮去除率分别下降到88.4%和87.3%,NO-2-N浓度明显上升,亚硝酸盐积累率由不足10%分别提高到14%和35%;在每个盐度下TN去除率都在70.0%以上,发生了同步硝化反硝化现象,并且在0.15~0.45的盐度范围内,同步硝化反硝化率(ESND)与盐度呈正相关。当盐度>0.45时,ESND开始下降,SBBR的同步硝化反硝化过程受到抑制。

关键词(KeyWords)： 盐度;SBBR;同步硝化反硝化;生物脱氮
