摘　　要：以西安市第三污水处理厂普通絮状活性污泥为接种污泥,采用人工配制的模拟生活污水,在SBR反应器中进行好氧颗粒污泥培养实验研究。在温度为室温,pH为7.0左右,曝气时间为150～180 min,沉淀时间9～120 min,曝气量为0.3～0.5 m3/h的实验条件下,成功培养出了好氧颗粒污泥,其颜色为浅黄色,粒径为1～2 mm,SVI为40 mL/g左右,MLSS为6 515 mg/L,平均沉降速度达到18.42 m/h。好氧颗粒污泥中含有大量的原生动物和后生动物,且成群出现,对COD、TN和TP的去除率分别达到95%、96%和98%。The experimental study of aerobic granular sludge in a sequencing batch reactor（SBR） was performed using a synthetic domestic wastewater and ordinary flocculent activated sludge as inoculation sludge.The conditions under which the successful cultivation of aerobic granular sludge is conducted are as follows： the temperature is room temperature,pH is about 7.0,aeration time is 150-180 min,sludge settling time is 9-120 min,and aeration rate is 0.3-0.5 m^3/h.The aerobic granular sludge has yellow appearance,with a size of 1-2 mm,SVI of 40 mL/g or so,and MLSS of 6 515 mg/L.The average settling velocity is up to 18.42 m/h.Aerobic granular sludge contains large amounts of protozoa,emerging in groups.The removal rates of COD,TN and TP are up to 95%,96% and 98% respectively.
