摘　　要：利用气升式内循环间歇反应器(SBAR),以酿造厌氧出水为原水,采用正交试验法培养好氧颗粒,对其快速启动的培养条件进行了研究。结果表明:最优培养条件是沉降时间30min,体积交换率50%,COD容积负荷4KgCOD/(m3d),水力停留时间480min,此条件下酿造厌氧出水中的COD、NH4+-N等指标均达到《发酵酒精和白酒工业水污染排放标准》(GB27631-2011)中的规定。The aerobic granular sludge is cultured in Sequencing Batch Airlift Reactors （SBAR） with brewing anaerobic influent as feed water. In order to solve the fast startup problems, the culture conditions are studied by orthogonal experiment. The experiment showes the optimum cultural condition, that sedimentation time is 30 minutes, volume exchange rate is 50%, volume loading of COD is 4 Kg- COD/（m3d） and hydraulic retention time is 480 minutes. Aerobic granular sludge cultured under this condition can effectively remove COD and NH4^＋ --N in brewing anaerobic effluent. The concentrations of COD and NH4^＋-N meets discharge standard of water pollutants for fermentation alcohol and distilled spirits industry （GB 27631--2011）.
