摘要
阐述了同步硝化反硝化的原理 ,研究了上向流曝气生物滤池 ( up-BAF)同步硝化反硝化工艺对城市生活污水的处理效果及规律。研究结果表明 ,同步硝化反硝化工艺对 COD、NH3-N的去除率随填料高度的增加而增加 ,最下层 5 0 cm厚滤料去除污染物的效果最好 ,该工艺脱氮效果不理想 ,TN去除率只有 30 %左右。当水力负荷在 2 .39m/h以下时 ,水力负荷对 COD、NH3-N去除的影响较小。
The principle of simultaneous nitrification and denitrification (SND) is summarized. The removal effect and regularity for treating municipal wastewater by up-flow biological aerated filter(up-BAF) were researched. The research showed that removal percent for COD and NH-3-N was positively interrelated to the height of media by SND technology. In the lower 50 cm, the removal efficiency was the best. The technology didn't have ideal effect for the removal of TN. The removal ratio of TN was just about 30%. When the hydraulic load was below 2.39 m/h, it had little influence on the removal of COD and NH-3-N.
