van Loosdrecht, Mark C.M. (author), Hao, Xiaodi (author), Wu, Yuanyuan (author)摘要： 好氧颗粒污泥技术具有占地面积小、能耗低、剩余污泥量少、抗冲击性强等优点，是<br/>一种可持续的污水处理技术。以北京某污水处理厂实际生活污水作为基质，在中试规模（有效容积<br/>为2.5 m3）反应器中进行好氧颗粒污泥培养，研究了颗粒污泥在低温条件下的稳定性。中试自夏季<br/>开始运行到次年春季结束，共计运行260 d。结果表明，采用我国实际低碳源市政污水可以培养出好<br/>氧颗粒污泥，污泥颗粒化程度可达94%，SVI5/SVI30为1.1 ~ 1.3。冬季低温会造成颗粒污泥的枝状结<br/>构增多、丝状菌生长，进而引起颗粒化比例略有下降，为80%~91%，污泥平均粒径降低，SVI5/SVI30升<br/>高至1.5 ~ 1.8。在冬季低温条件下，通过优化调控进水流量...journal article 2022

van den Berg, L. (author), Toja Ortega, S. (author), van Loosdrecht, Mark C.M. (author), de Kreuk, M.K. (author)Aerobic granular sludge (AGS) is an advanced biofilm-based technology for wastewater treatment. Diffusion of substrates into the granules is a key aspect of this technology. Domestic wastewater contains soluble organic substrates of different sizes that could potentially diffuse into the granules. In this study, the relation between the...journal article 2022

Toja Ortega, S. (author), van den Berg, L. (author), Pronk, M. (author), de Kreuk, M.K. (author)In aerobic granular sludge (AGS) reactors, granules of different sizes coexist in a single reactor. Their differences in settling behaviour cause stratification in the settled granule bed. In combination with substrate concentration gradients over the reactor height during the anaerobic plug-flow feeding regime, this can result in functional...journal article 2022
