The slow initiation of anammox for treating typical domestic wastewater and the relatively high footprint of wastewater treatment infrastructures are major concerns for practical wastewater treatment systems. Herein, a 300 m³/d hybrid biofilm reactor (HBR) process was developed and operated with a short hydraulic retention time (HRT) of 8 h. The analysis of the bacterial community demonstrated that anammox were enriched in the anoxic zone of the HBR process. The percentage abundance of Candidatus Brocadia in the total bacterial community of the anoxic zone increased from 0 at Day 1 to 0.33% at Day 130 and then to 2.89% at Day 213. Based upon the activity of anammox bacteria, the removal of ammonia nitrogen (NH₄⁺-N) in the anoxic zone was approximately 15%. This showed that the nitrogen transformation pathway was enhanced in the HBR system through partial anammox process in the anoxic zone. The final effluent contained 12 mg/L chemical oxygen demand (COD), 0.662 mg/L NH₄⁺-N, 7.2 mg/L total nitrogen (TN), and 6 mg/L SS, indicating the effectiveness of the HBR process for treating real domestic wastewater.

厌氧氨氧化处理典型生活废水的缓慢启动和废水处理基础设施的相对较高的足迹是实际废水处理系统的主要问题。在此，开发了 300 m ³ /d 混合生物膜反应器 (HBR) 工艺，并以 8 小时的短水力停留时间 (HRT) 运行。细菌群落的分析表明，厌氧氨氧化在 HBR 过程的缺氧区富集。Candidatus Brocadia在缺氧区总细菌群落中的丰度百分比从第 1 天的 0 增加到第 130 天的 0.33%，然后增加到第 213 天的 2.89%。 NH ₄ ⁺-N) 在缺氧区约为 15%。这表明在 HBR 系统中通过缺氧区的部分厌氧氨氧化过程增强了氮转化途径。最终出水含有 12 mg/L 化学需氧量 (COD)、0.662 mg/L NH ₄ ⁺ -N、7.2 mg/L 总氮 (TN) 和 6 mg/L SS，表明 HBR 工艺对处理真正的生活污水。
