| 摘 要： | 采用气升式间歇反应器研究了好氧污泥颗粒化过程,分别考查了厌氧颗粒污泥和活性污泥为接种污泥时好氧污泥颗粒化过程及其特性的不同,并且分析了循环时间为4 h和12h时好氧颗粒污泥的菌群形态和粒径分布.实验结果表明:活性污泥接种形成的好氧颗粒污泥相对密度达1.025,含水率96%,而厌氧颗粒污泥驯化形成的好氧颗粒污泥相对密度为1.008 7,含水率98%;在4 h循环时间下,颗粒粒径主要在1.5~2.0 mm,杆菌为优势菌,而在12 h循环时间下,颗粒污泥粒径主要分布在1.0~1.5 mm,球菌为优势菌.

| Abstract: | Aerobic sludge granulation was observed in two sequencing batch airlift reactors(SBAR) while anaerobic granules and activated sludge acted as seed sludge respectively.Microbial morphology and size distribution of aerobic granules were analyzed under cycle time of 4 h and 12 h.It was found that relative density of aerobic granules was 1.025 and ratio of water containing was 96% when activated sludge acted as seed sludge,but only 1.008 7 and 98% when anaerobic granules acted as seed sludge.At cycle time of 4 h,diameter of aerobic granules was 1.5~2.0 mm and bacilli was dominant in the reactors,but diameter was 1.0~1.5 mm and cocci was dominant at cycle time of 12 h. |
