A/O生物接触氧化处理农村生活污水研究

采用逐步提高水力负荷的方式，耗时20 d，成功启动A/O生物接触氧化反应器。反应器启动成功后，COD、NH⁺₄-N、TN、TP的去除率分别为88.56%、89.23%、70.77%、68.36%。将调试完成的A/O生物接触氧化反应器用于处理农村生活污水，系统运行7 d 后，出水ρ（COD）为 45.00 mg/L，ρ（NH⁺₄-N）为 6.54 mg/L，ρ（TN）为 18.00 mg/L，ρTP）为 0.30 mg/L，达到河南、山东、北京等地《农村生活污水处理设施水污染物排放标准》一级标准排放要求，且设备运行稳定可靠。

Study on A/O biological contact oxidation treatment of rural domestic sewage

By gradually increasing the hydraulic load，it took 20 days to successfully start the A/O biological contact oxidation reactor.After the reactor was started successfully，the removal rates of COD，NH⁺₄-N，TN，and TP removal rate were 88.56%，89.23%，70.77% and 68.36%.The commissioned A/O biological contact oxidation reactor was used to treat rural domestic sewage.After the system was operated for 7 days，the effluent ρ（COD） was 45.00 mg/L，ρ（NH⁺₄-N） was 6.54 mg/L，ρ（TN） was 18.00 mg/L，ρ（TP） was 0.30 mg/L，it met the first-level discharge requirements of the "Water Pollutant Discharge Standards for Rural Domestic Sewage Treatment Facilities" in Henan，Shandong，Beijing and other places，the equipment was stable and reliable.
