中文摘要 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，基质中分别投加葡萄糖和丙酸钠启动SAD工艺.结果表明，常温条件（13~22℃）下，进水投加30 mg·L^-1葡萄糖，SAD工艺耦合效果良好，平均出水总氮浓度为6.41 mg·L^-1.相较于厌氧氨氧化工艺，SAD工艺出水总氮浓度降低了42%；低温环境（10~13℃）中，投加30 mg·L^-1葡萄糖，SAD工艺稳定性受到破坏并向反硝化工艺转变；常低温环境（10~22℃）中，基质中投加30 mg·L^-1丙酸钠，SAD工艺均有良好的处理效果，平均出水总氮浓度为6.54 mg·L^-1，丙酸钠对低温SAD工艺影响较小. 英文摘要 Lab-scale anaerobic ammonia oxidation and denitrification (SAD) processes were operated simultaneously in a municipal waste water treatment plant (WWTP). Sewage treated by the A/O and nitrification process was used as the substance to start up an anaerobic ammonia oxidation filter reactor. Adding glucose and sodium propionate to influent was used as the substance to start up the SAD filter reactor after the successful start-up of the ANAMMOX reactor. The SAD process performed well with an average total nitrogen concentration in the effluent of 6.41 mg·L^-1 when 30 mg·L^-1 glucose was added to the effluent sewage at ambient temperature. Compared with the ANAMMOX process, the total nitrogen concentration in the effluent from the SAD process decreased 42%. The stability of the SAD process was destroyed and the SAD process turned into a denitrification process when 30 mg·L^-1 glucose was added in the influent sewage in a low temperature environment. In normal and low temperature environments, the SAD process functioned well, and the average total nitrogen concentration of the effluent was 6.54 mg·L^-1 when 30 mg·L^-1 sodium propionate was added in the influent sewage. Compared with glucose, sodium propionate had little influence on the SAD process.
