摘　　要：本实验利用改装UASB(MUASB)装置在不同启动方式下培养好氧颗粒污泥,并对高浓度废水处理效果进行监测。通过比较研究发现,实验1中投加活性炭后采用分层曝气,实现了好氧颗粒污泥的快速培养。培养出的好氧颗粒污泥颗粒大,活性强,水质处理效果较好。实验1中成熟的好氧颗粒污泥粒径最大为1.5～2.5 mm,MLSS最高为15 290 g/L。对COD负荷≥8000 mL/g的污水处理效率保持在90%以上,对NH4+-N的处理效率稳定在70%左右。The paper was an attempt to cultivate the aerobic granular sludge with wastwater in the different start-up of Modified Upflow Anaerobic Sludge Blanket Reactor（MUASB）.The treating effects of wastewater were monitored simultaneously.By dosing activated carbon and using stratified aeration of Experiments 1,aerobic granular sludge was cultivated in five days.The aerobic granular sludge particles was big and had high activity and could treat water better.The results showed that mature stage of the aerobic granular sludge with diameter about 1.5-2.5 mm,and the MLSS up to 15 290 g/L were observed.The aerobic granular sludge showed the high concentration of COD removal rate at 97 %,and NH＋4-N removal rate at 70%.
