| 摘 要： | 为研究启动方式对同步短程硝化、厌氧氨氧化耦合反硝化(SNAD)颗粒污泥工艺的影响,低温(12.7~18.3℃)条件下,R1和R2反应器分别通过先启动全程自养脱氮(CANON)工艺和先启动厌氧氨氧化耦合反硝化(SAD)工艺的方式逐步启动SNAD颗粒污泥工艺.结果表明,R1反应器启动成功后,氨氮几乎完全去除,总氮去除率达到86.7%.低氨氮浓度运行时,出水总氮去除率下降至75.3%,出水总氮浓度在10 mg·L~(-1)左右,NOB存在过量增殖现象,出水总氮浓度超过北京市水污染物排放标准一级A规定.R2反应器启动成功后,出水几乎不含氨氮,总氮去除率在89.1%左右,略高于R1反应器.低氨氮浓度运行时,出水氨氮浓度小于1.0 mg·L~(-1),出水总氮浓度小于6 mg·L~(-1),出水氨氮和总氮浓度满足地标一级A标准.先启动SAD工艺可以在启动初期通过厌氧运行将NOB逐渐淘汰出系统内,维持了系统的稳定性,为后续曝气启动SNAD工艺提供了良好的基础,维持了反应器的稳定运行,实现出水总氮长期排放达标.
