Anaerobic granular sludge was inoculated to an aerobic SBR, where CH3COONa was used as the carbon source. Observations on the change of granules' shape and structure revealed that the granules experienced a shape-keeping and component-replacing process. The sludge concentration increased at first 4 weeks and then decreased to reach a constant of 5g/L at 35d with its SVI of 30 - 40mL/g. Granular sludge dominated in the reactor and suspended sludge concentration was less than 0.5g/L during the end of the process. Anaerobic granular sludge, in which spheral bacteria was the main microorganism, was successfully developed to aerobic granular sludge in which filamentous and bacillius bacteria were the dominant microorganism.
将厌氧颗粒污泥接种到以CH3COONa为碳源的好氧SBR中。对颗粒形状和结构变化的观察表明，颗粒经历了形状保持和成分替换的过程。污泥浓度最初在4周内增加，然后下降，在35天时降至5g/L的常数，其污泥体积指数为30 - 40mL/g。在该过程结束时，反应器中以颗粒污泥为主，悬浮污泥浓度小于0.5g/L。以球形细菌为主要微生物的厌氧颗粒污泥成功地发展成为以丝状菌和杆菌为优势微生物的好氧颗粒污泥。
