摘要
采用推流式固定化絮体生物反应器培养出高活性的厌氧氨氧化 (ANAMMOX)红色颗粒污泥 .在稳定运行后 ,反应器的NH+ 4 N和NO-2 N去除率皆大于 98% ,TN平均去除率为 86 % ,NO-3 N的生成率约为 14 % ,TN去除负荷达 2 5 6kg/ (m3 ·d) .同时考察了进水基质比例对反应器性能的影响 ,并用扫描电镜观察了颗粒结构 .
It is feasible that the ANAMMOX bacteria can be enriched and cultivated to red granular in plug flow immobilized floc bioreactor. Average ammonium and nitrite removal rate are more than 98%, and average total nitrogen removal rate is 86% combined with 14% nitrate production; the removal volumetric total nitrogen load is 2.56kg/(m3·d). The influence of the influent substrate ratio of ammonium to nitrite on reactor's performance has been studied. The granule structure has been observed by the scan electro-microscope.
