以多点进水倒置AAO工艺处理低碳源城市合流污水，考察处理效果，并选择最佳工况和工艺参数。结果表明：脱氮除磷效果较好，适合低碳源的城市污水处理；污泥回流比和内回流比不宜过大；出水NH3-N，TN，TP，SS和CODCr均满足GB 18918-2002《城镇污水处理厂污染物排放标准》一级（B）排放标准，且稳定可靠；曝气区ρ（MLSS）约3.0 mg/L，SVI在100 mL/g左右，污泥沉降性能较好。
以多點進水倒置AAO工藝處理低碳源城市閤流汙水，攷察處理效果，併選擇最佳工況和工藝參數。結果錶明：脫氮除燐效果較好，適閤低碳源的城市汙水處理；汙泥迴流比和內迴流比不宜過大；齣水NH3-N，TN，TP，SS和CODCr均滿足GB 18918-2002《城鎮汙水處理廠汙染物排放標準》一級（B）排放標準，且穩定可靠；曝氣區ρ（MLSS）約3.0 mg/L，SVI在100 mL/g左右，汙泥沉降性能較好。

Parted infall reversed AAO processes were applied to treat municipal wastewater with low carbon contents. Removal performance was investigated and the desirable operation conditions were determined. The results indicated that reversed AAO process with influent distribution is recommended by which nitrogen and phosphorus can be removed more. The large returned ratios of sludge and the mixed liquid are not advisable. NH3-N,TN,TP,SS and CODCr in effluent can meet the required emission limits of the first class in Discharge standard of pollutants for municipal wastewater treatment plant (GB 18918-2002). MLSS is about 3.0 mg/L and SVI is 100 mL/g with effective settlement feature of the sludge.
