摘　　要：采用投料A2/O脱氮除磷工艺在广州某城市污水处理厂进行中试,考察在设计参数下该工艺处理低浓度城市污水的脱氮除磷效果。结果表明,投加填料能够增强系统抗冲击能力,保持出水水质稳定。出水COD平均为26.1mg·L-1,TN平均为9.6mg·L-1,NH3-N平均为1.1mg·L-1,TP平均为0.28mg·L-1,并且出现了明显的反硝化除磷现象。投加填料能够增大系统的处理量,节约处理成本。Pilot plant test was conducted on the suspended carrier added A2/O process for nitrogen and phosphorus removal in a municipal wastewater treatment plant in Guangzhou, and the nitrogen and phosphorus removal was investigated by treating the low concentration municipal wastewater under the designed conditions. The results proved that the suspended carrier could raise the stability of the system and keep the quality of the effluent steady. The effluent COD is 26.1 mg· L^-1 in average, with TN, NH3-N and TP content ration of 9.6 mg· L-1, 1.1 mg· L^-1 and 0.28 mg · L^-1 respectively. The denitrifying phosphorus removal occur evidently. Adding the suspended carrier can increase the treating volume, accordingly it can save the treating cost.
