| 中文摘要: |
| 配制模拟生活污水，利用序批式活性污泥法（SBR）反应器在连续曝气条件下进行好氧颗粒污泥（AGS）的培养，研究完全好氧〖JP2〗模式下AGS的快速培养及其同步脱氮除碳特性。结果表明：污泥第7天即出现颗粒化，平均粒径032 mm，〖JP〗连续曝气SBR中NH3〖FK（W。*9〗〖CD*2〗〖FK）〗N、TN、COD的去除率分别为953%、774%、975%；高通量测序分析结果显示，相较接种絮状污泥，与颗粒化相关的丝状菌属、动胶菌属丰度显著提高，HN-AD菌作为脱氮功能微生物，其物种多样性也得以丰富。 |
| 英文摘要: |
| The characteristics of rapid cultivating of AGS in fully aerobic mode and simultaneous removal of nitrogen and carbon from simulated domestic sewage were studied by using sequencing batch reactor(SBR) for cultivating aerobic granular sludge (AGS) under continuous aeration conditions. The results showed that the sludge granulated on the 7th day, with an average particle size of 0.32 mm. The removal rate of NH3 N, TN, and COD in continuous aeration SBR 〖JP3〗were 95.3%， 77.4%， and 97.5%, respectively. High throughput sequencing analysis results showed that compared with inoculated flocculent sludge, the abundance of Meganema and Zoogloea which related to granulation increased significantly. As denitrifying microorganism, the diversity of HN AD bacteria was enriched. |
