摘　　要：研究了低温条件下中试BioDopp工艺对于低碳氮比市政污水中污染物的去除效果。结果表明,BioDopp工艺稳定运行阶段控制运行参数为回流体积比20倍左右,DO的质量浓度0.3~0.8 mg/L、水温9~12℃时,出水COD平均为35.66 mg/L,NH_(3^-)N、TN的质量浓度平均分别为1.0、11.67 mg/L,达到了设计出水排放标准。同时确定BioDopp生化工艺与芽孢杆菌结合应用时,适宜DO的质量浓度应控制为0.3~0.8 mg/L。A pilot plant test was proceeded to investigate removal efficiency of BioDopp process for the removal of pollutants in municipal wastewater with low ratio of carbon to nitrogen under the condition of low temperature. The results showed that in the stable operation stage of BioDopp process,operation parameters were controlled as following： the reflux volume ratio was 20 times, mass concentration of DO was 0.3～0.8 mg/L, water temperature was 9～12 ℃, effluent COD was 35.66 mg/L, and mass concentration of NH_（3-）N and TN were 1.01 and 11.67 mg/L, respectively, which reached the design discharge standard. The optimal mass concentration of DO for the combination of Bio Dopp and Bacillus should be controlled in the range of 0.3～0.8 mg/L.
