摘　　要：采用序批式反应器（SBR）,以不同的缺氧搅拌时长来控制颗粒污泥粒径,探究不同粒径的好氧颗粒污泥系统对高浓度氨氮废水的处理特性。研究表明不同控制策略下的4个反应器（R1~R4）分别得到的主要粒径分布为0.4~0.6,0.6~0.8,0.6~0.8,1.0~1.2 mm;系统稳定阶段氨氮平均去除率分别为83.6%、79.4%、77.7%和73.1%。此外,好氧颗粒污泥系统处理高氨氮废水时,颗粒粒径最小的反应器（R1）在氨氮、总氮和磷酸盐方面具有较好的去除效果,但其颗粒污泥的物化性能并没有体现出较高优势。The size control of aerobic granular sludge and its effect on treatment of wastewater with high nitrogen concentration were studied. The particle size control was achieved successfully by keeping different mixing time in anoxic phase. The results showed that aerobic granular sludge system under various control performed stability and efficiency. The main particle size distribution ranges were 0. 4 ~ 0. 6 mm,0. 6 ~ 0. 8 mm,0. 6 ~ 0. 8 mm,1. 0 ~ 1. 2 mm,respectively,and the average ammonia removal rates in four reactors（ R1 ~ R4） were 83. 6%,79. 4%,77. 7%,73. 1%,respectively. R1 with the smallest particle size of granular sludge had a high removal performance on removing ammonia,total nitrogen and phosphate,while systems with other particle sizes of granular sludge did not achieve so good performance.
