摘    要:好氧颗粒污泥是一种应用于废水生化处理中的新型活性污泥技术,具有结构致密,沉降性能优越,生物处理能力强等特点.通过在气升式内循环间歇反应器启动阶段,接种活性污泥的同时添加活性炭颗粒(AC)的方法,缩短好氧颗粒污泥颗粒化时间,成功培养出了沉降速率大,结构稳定,除氮效果好的活性炭好氧颗粒污泥.并考察了活性污泥絮体-出现颗粒污泥-成熟颗粒污泥-储存-解体-修复的过程,验证了载体强化型好氧颗粒污泥处理低碳氮比废水的可行性.实验结果证明:活性炭好氧颗粒污泥反应器稳定运行时,COD、氨氮、总氮去除率分别可以达到80% ~ 90%、99%、80%.将成熟活性炭好氧颗粒污泥储存12个月,经过恢复培养,物理特性及脱氮性能能够完全恢复到储存前的水平.

关 键 词:好氧颗粒污泥  活性炭  废水处理

Abstract:The technology of aerobic granules sludge is a kind of new biochemical technology to treat waste water.It has compact structure,good settling ability and a excellent ability of biological treatment.Aerobic granules with carrier were successfully cultivated through adding activated carbon(AC) grain together with inoculated sludge.They have stable structure,good settling ability and excellent removal effect of N.This study investigated the process of floc sludge-small particles-ripe aerobic granules,storage,disintegration,recovery and the feasibility in low C/N wastewater treatment.The removal efficiency of COD,NH+4-N and TN reached 80%~90%,99%,80% respectively.After storing the AC aerobic granular sludge for 12 months and forteen days recovery,the morphology and properties of the granules recover completely.
Keywords:aerobic granular sludge  activated carbon  waste water treatment
