| The HSBNR process, which contained attached and suspended cells, could treat a high-strength ammonium wastewater and stably achieved long-term SBNR (over 1.5 years in HSBNR II). The lack of NO3 in the HSBNR reactors was achieved by maintaining a moderately high FA concentra-tion (20 < FA < 25 mg/L) and a low DO (<1 mg/L), which worked together to eliminate nitrate accumulation. The overall DCOD/DNOx-N ratio was 2.5–3.2, a value clearly dominated by shortcut denitrification in the anoxic tank, where 66–76% of the COD removal occurred. The biofilm carriers in the aerobic tank selectively enriched for ammonium oxidizers in the aerobic tank selecting against nitrite oxidizers. In particular, the selective accumulation of ammonium oxidizers in the porous biofilm carrier increased their SRT by over 50% from the total-biomass SRT. In addition, the low DO in the aerobic tank enhanced direct denitrification of NO2, which selected against nitrite oxidizers and enhanced shortcut denitrification. |

| 包含生物膜和懸浮污泥的HSBNR 工藝可處理高濃度氨廢水，并可以實現(xiàn)長期的短程脫氮除磷（在HSBNR II中超過1.5年）。適當高濃度的游離氨（20 – 25 mg/L）和低濃度溶解氧(<1 mg/L)可以聯(lián)合作用以減少硝酸鹽的積累，令HSBNR反應(yīng)池中的NO3處于缺乏狀態(tài)。DCOD與DNOx-N 總體比率為2.5–3.2。這個結(jié)果明顯是由厭氧池中的短程反硝化作用造成的。該過程可去除66–76%的COD。好氧池中的生物膜選擇性地富集氨氧化細菌，而無氧池中的生物膜擇性地抑制亞硝酸鹽氧化細菌。特別地，氨氧化細菌會選擇性地積累在多孔的生物膜材料上，從而可使增加的污泥停留時間超過總污泥停留時間的50%。此外，無氧池中的低溶解氧可提高NO2直接反硝化的效果，從而選擇性地抑制亞硝酸鹽氧化細菌并提高短程反硝化效果。 |
