摘要：

为研究接种污泥对好氧颗粒污泥稳定性的影响，将以城市污水处理厂的活性污泥和以啤酒废水处理厂的活性污泥为接种污泥培养的成熟好氧颗粒污泥封存后重新启动运行，探讨其理化性能、降解性能的恢复以及种群结构的变化情况。结果表明：接种污泥对好氧颗粒污泥的稳定性具有一定的影响，沉降性能好、生物活性强的啤酒废水处理厂的接种污泥形成的颗粒污泥形态恢复快，约需35 d，沉降性能恢复为贮存前的93%，具有较好的稳定性；对COD、NH₃-N的降解效果与用城市污水厂的污泥接种形成的好氧颗粒污泥相近，但其对TP有更好的去除效果，COD、NH₃-N、TP的去除率分别达95.10%、91.80%、94.00%。变性梯度凝胶电泳法(DGGE)分析表明：啤酒废水厂污泥接种形成的颗粒污泥的群落结构多样性十分丰富，优势种属达20个操作分离单元(OTUs)；而城市污水厂污泥接种形成的颗粒污泥中优势种属只有11个OTUs。

Abstract:

In order to investigate the influence of seed sludge on the stability of aerobic granular sludge, aerobic granules which was cultivated using different kinds of seed sludge were restarted in sequencing batch airlift reactor after a prolonged storage period, the influence of seed sludge on the properties and microbial community of aerobic sludge granular were studied. The results showed that seed sludge had some effect on the stability of aerobic granular, the morphology of aerobic granular developed using activated sludge taken from beer wastewater treatment plant, which has better settle-ability and biological activity, can recover quickly after 35 d restarting, its settleability reached 93% of fresh aerobic granular, and its removal rate of COD,NH_3-N was similar to that of aerobic granular cultivated using activated sludge taken from domestic wastewater treatment plant, but its removal rate of TP was better, they were 95.10%,91.80% and 94.00% respectively. DGGE profiles indicated that the microbial community diversity was abundant for seed sludge from beer wastewater treatment plant with its dominant microbial species of 20 operational taxonomy units( OTUs), and even simple for seed sludge from domestic wastewater treatment plant with the dominant species of 11 OTUs.

Key words: aerobic granular sludge, seed sludge, stability, microbial community
