摘要

摘要: 在SBR（Ⅰ）反应器中快速启动颗粒-絮状污泥耦合单级自养脱氮系统，研究启动前后颗粒、絮状污泥脱氮性能的变化。取启动前和系统构建成功后的污泥进行批试实验，通过甲醇抑制厌氧氨氧化菌（AAOB）活性来研究厌氧氨氧化和反硝化比例的变化。絮状污泥总氮去除率（NRE）从启动前的10.14%提高至启动成功后的89.70%，其中厌氧氨氧化脱氮占比从2.23%提高到83.70%，反硝化脱氮占比从7.91%减少到5%~6%；颗粒污泥的NRE从启动前3.90%提高至启动成功后的83.20%，厌氧氨氧化占比从不足1%提高到80.20%左右，反硝化占比从7.72%减少到2%~3%。

Abstract: In SBR (Ⅰ) reactor, the granular-flocculent sludge coupled single-stage autotrophic nitrogen removal system was rapidly started, and then the change of nitrogen removal performance of granular and flocculent sludge before and after start-up was studied. The sludge before start-up and after the start of the system was sampled to carry out batch experiments and the changes of denitrification and anaerobic ammonium oxidation denitrification performance were investigated by inhibiting the activity of anaerobic ammonium oxidizing bacteria (AAOB) by methanol. The total nitrogen removal rate (NRE) of flocculent sludge increased from 10.14% before start-up, to 89.70% after start-up, of which the proportion of anaerobic ammonia oxidation increased from 2.23% before start-up to 83.70%, and the proportion of denitrification decreased from 7.91% to 5%~6%. The NRE of granular sludge increased from 3.90% before start-up to 83.20% after start-up, the proportion of anaerobic ammonium oxidation increased from less than 1% to 80.20%, and the proportion of denitrification decreased from 7.72% to 2%~3%.
