摘要
在连续流上流式好氧反应器中接种厌氧颗粒污泥进行硝化颗粒污泥的培养及其硝化性能研究,结果表明,通过逐步提高进水N/C值能培养出高活性硝化颗粒污泥;进水氨氮浓度对系统的硝化性能没有显著影响,系统对氨氮的去除率>85%;当氨氮容积负荷>0.40kgNH4+-N/(m3.d)时,系统实现短程硝化,亚硝酸盐氮积累率平均高达83%。
The cultivation of nitrifying granular sludge and its nitrifying performance was studied by seeding anaerobic granular sludge in the continuous up-flow aerobic reactor. The results show that ni- trifying granules with high activity can be cultivated by gradually increasing the influent N/C value. The removal rate of ammonia nitrogen is above 85%, while the influent ammonia nitrogen concentration has no significant effect on the nitrifying performance. When ammonia nitrogen volumetric loading is above O. 40 kgNH4＋ -N/（ m3 · d）, the short-cut nitrification takes place, and the average nitrite nitrogen accu- mulation rate is up to 83%.
