摘要
以好氧-厌氧耦合反应器中的活性污泥为种泥,采用通过控制运行条件在SBAR中成功地培养出了好氧颗粒污泥。研究表明,该好氧颗粒污泥具有良好的去除COD和TOC的性能。好氧颗粒污泥成熟后平均直径为0.5~2.0mm,沉降速度为14.9~31.8m/h,反应器对COD和TOC的去除率分别小于91.42%和93.46%。
Activated sludge,which comes from AAC reactor was used as seeding sludge.Aerobic granular sludge was cultivated in sequencing batch airlift reactor(SBAR) fed with synthetic wastewater by controlling operational conditions.It is demonstrated that simultaneous nitrification and denitrification,and COD removal can be achieved with high performance.The matured aerobic granular sludge has an average diameter of 0.5～2.0mm and settling rate of 14.9～31.8m/h.The removal rate of COD and TOC as less than 91.42% and 93...
