摘　　要：以厌氧颗粒污泥为接种泥,采用人工配制的模拟生活污水,在SBR反应器中成功培养出好氧颗粒污泥。试验表明：以二次成核说作为理论支持,通过提高COD负荷和逐渐减少污泥沉降时间所造成选择压促进好氧颗粒污泥的形成。所形成的颗粒结构密实,沉降性能好,生物活性高,外表呈橙黄色,粒径在0.5-1 mm,SVI为40 mL/g,MLSS为7 037 mg/L。该SBR系统对COD、氨氮的去除率均达到95%以上,对TP的去除率也达到80%,具有良好的同步脱氮除磷效果。The successful cultivation of aerobic granular sludge in sequencing batch reactor（SBR） is performed in synthetic domestic wastewater and conventional flocculent activated sludge as aerobic granular sludge.According to second nucleation theory,aerobic granular sludge can be cultured by decreasing the sludge sedimentation time and increasing COD loading rate resulting in the selective pressure.The aerobic granular sludge has very regular structure,better settling performance,high bioactivity,and an orange yellow appearance with a size of 0.5 to 1.0 mm,SVI of 40 mL/g and MLSS of 7 037 mg/L.With average removal rate of ammonia nitrogen,COD is above 95% and that of TP is above 80%.
