摘　　要：采用倒置A2/O-MBR工艺,对北方某污水处理厂的合流制城镇生活污水进行脱氮除磷试验研究。试验结果表明,该工艺对COD、NH3-N、SS的去除效果良好,可达到城镇污水处理厂污染物排放标准(GB 18918-2002)一级A标准;对于氮磷的去除,出水TN<25 mg/L,TP<2.2 mg/L。造成这种结果的主要原因是进水碳源不足。为了提高脱氮除磷效果,采取了投加碳源醋酸钠等手段来辅助脱氮除磷,最终各指标均达标排放。The inverted A2/O-MBR process was used to treat the municipal wastewater of combined system,and the removal efficiency was studied.Result showed that the process was efficient in removal of COD,NH3-N,SS and satisfactory to grade A of national discharge standard of GB 18918--2002.With removal efficiency of TN and TP, the effluent concentration only is TN〈25 mg/L and TP〈2.2 mg/L due to no enough carbon in wastewater.To improve the effect of nitrogen and phosphorus removal,NaAc was used,and the effluent quality reaches the first level A criteria specified in GB 18918--2002.
