摘　　要：采用序批式活性污泥（SBR）工艺,分别以葡萄糖（R1反应器）和乙酸钠为基质（R2反应器）运行102 d,对培养成熟的颗粒污泥特性进行研究.结果表明：R1反应器中以球菌为主,R2反应器中以杆菌、球菌为主;在颗粒刚成熟时,R2反应器的颗粒大些,且集中,粒径在0.1-1.0 mm,随着颗粒成熟期的延长,R1反应器的粒径要大些,最大为2.2 mm;R1和R2反应器的耗氧速率（OUR）分别为1.184和0.944 mg/（L.min）,比耗氧速率（SOUR）分别为0.838和0.825 mg/（g.min）;有机污染负荷为600-1 200 mg/L时,R1和R2反应器的CODCr去除率均达到95%-98%.The characteristics of matured aerobic granular sludge were studied using synthetic wastewater in two sequencing batch reactors （SBRs） with glucose （in R1 reactor） and acetate （in RE reactor） as culture carbon sources respectively. The results of 102 days＇ operation revealed that in R1 the size distribution displayed a wide range of O. 1 - 2.2 mm, spheral bacteria were the main microorganisms, oxygen uptake rate （OUR） and specific oxygen uptake rate （SOUR） were 1. 184 mg/（L·min） and 0.838 mg/（g·min）, respectively, while in R2 the size distribution had a small rang of 0.1 - 1.0 nun, bacillius and spheral bacteria were the dominant microorganisms, OUR and SOUR were 0.944 mg/（L·min） and 0.825 mg/（g·min）, respectively. In both reactors the CODcr removal efficiency was up to 95% - 98% even with the CODcr load from 600 to 1 200 mg/L.
