| 摘要: |
| 为提高反应器的氮素去除率，在市政污水处理厂进行同步厌氧氨氧化反硝化(SAD)工艺小试.以A/O除磷和亚硝化工艺处理后的生活污水为基质，启动厌氧氨氧化滤柱.反应器启动成功后，基质中投加有机碳源促进反硝化菌生长，启动SAD工艺，研究碳源质量浓度对SAD工艺的影响.由于葡萄糖对厌氧氨氧化菌抑制作用较小，成本较低，作为SAD工艺的有机碳源.结果表明：常温条件下，进水分别投加10，20和30 mg/L Glu，SAD工艺耦合效果良好，平均出水总氮质量浓度为9.16，8.10和6.41 mg/L.相较于厌氧氨氧化工艺，SAD工艺出水总氮质量浓度降低了16%~42%，常温条件下取得了良好的运行效果.冬季水温为10~12 ℃，基质中投加30 mg/L Glu，SAD工艺稳定性受到破坏并向反硝化工艺转变，出水氨氮质量浓度由0.5 mg/L增长至6.2 mg/L.水温对SAD工艺有较大影响，低温条件下SAD工艺中厌氧氨氧化菌与反硝化菌的竞争中占据劣势，工艺稳定性受到破坏.将基质Glu质量浓度降低到20 mg/L，出水总氮质量浓度为6.5~8.5 mg/L，冬季SAD工艺出水氨氮和总氮质量浓度满足北京市地方标准的A类排放标准.

| Abstract: |
| Lab-scale simultaneously anaerobic ammonia oxidation and denitrification (SAD) process was operated in Municipal Waste Water Treatment Plant (WWTP). Sewage treated by A/O and nitrification process was served as substance to start up anaerobic ammonia oxidation filter reactor. Adding organic carbon-source to influent was served as substance to start up SAD filter reactor after successful start-up of Anammox reactor. Glucose was selected as organic carbon-source because it is harmless and inexpensive. The result show that SAD process performed well with 10, 20, and 30 mg/L Glucose added to effluent sewage at ambient temperature and average total nitrogen concentration of effluent was 9.16, 8.10, and 6.41 mg/L. Compared with Anammox process, SAD process performed better and total nitrogen concentration in effluent decreased 16-42 percents. Stability of SAD process was destroyed and SAD process turned to denitrification process when 30 mg/L Glucose was added in influent sewage in winter. Ammonia in effluent increased from 0.5 mg/L to 6.2 mg/L. The results indicate that temperature has superior effect on SAD process. The total nitrogen concentration in effluent varied from 6.5 to 8.5 mg/L when concentration of Glucose decreased to 20 mg/L. In winter, the effluent of SAD process reached the 1A level of integrated discharge standard of water pollutants applied in Beijing City.
