摘　　要：采用逐步提高进水负荷的方式,耗时65 d,成功启动了水解酸化-接触氧化-MBR生物反应器。反应器启动成功后,COD与NH_3-N的去除率分别为85%和80%,MBR膜过滤时间为100 min,反洗时间为4 min。将调试完成的"水解酸化-接触氧化-MBR"一体化设备用于处理农村污水,系统运行90 d后,出水ρ(COD)为35 mg/L,ρ(NH_3-N)为3.7 mg/L,ρ(SS)为5.1 mg/L,ρ(TP)为0.3 mg/L,均达到DB 13/2171—2015《农村生活污水排放标准》一级A标准和GB 18918—2002《城镇污水处理厂污染物排放标准》一级A排放标准,且设备运行稳定可靠。The hydrolytic acidification-biological contact oxidation-MBR integration equipment process was used to treat rural domestic sewage.After 65d,the bloreactor was successfully started up by gradually improving the way of water load,and the removal rates of COD and NH3^+-N were 85%and 80%,respectively,fihration time of the MBR.membrane was 100min,the backwashing time was 4min.Then integrated treatment equipment was carried out to treat the rural domestic sewage.After operation for 90days,the average effluence of COD,NH3-N,SS,TP was 3.7,5.1,0.3mg/L.The effluence reached the "Rural Sewage Discharge Standard"(DB 13/2171--2015)level A and "Urban Sewage Treatment Plant Pollutant Discharge Standards"(GB 18918--2002)level A,and the equipment operation was stable and reliable.
