摘　　要：为探讨厌氧氨氧化MBBR的快速启动及处理低浓度含氮废水特性,采用某城市污水处理厂A2/O系统中缺氧池填料作为MBBR的载体直接启动并运行。结果表明,经过248 d启动,MBBR处理负荷(以N计)达到5046.57 mg·(m^2·d)^-1,Anammox活性(以NH-N计)达到4627.25 mg·(m^2·d)^-1;NH-N与NO-N的消耗量和NO3--N的生成量之间的比值关系和反应器内各微生物活性及反应器运行条件及方式有关。采用基质利用速率测定方法对Anammox活性进行测定,探讨Anammox菌在常温条件下的增殖情况,确定Anammox菌增殖系数为0.0261 d^-1。Anammox菌MBBR的成功启动为Anammox技术处理低浓度含氮废水提供了参考。In order to investigate the rapid start-up of anammox process in MBBR and the treatment of low nitrogen concentration wastewater,the fillers from an anoxic tank of A2/O system in a municipal wastewater treatment plant was taken as MBBR carrier for direct start-up and running.The result showed that after 248 days start-up,the treating loading of MBBR as nitrogen could reach 5046.57 mg·(m^2·d)^-1,and anammox activity as NH4+-N could reach 4627.25 mg·(m^2·d)^-1.The ratios of NH4+-N and NO2--N consumption to NO3--N production were related to the activity of microorganisms in MBBR and its running conditions and modes.A test for the substrate utilization rate was used to determine the anammox activity and study the proliferation of at room temperature.The corresponding proliferation coefficient of anammox bacteria was 0.0261 d^-1.The successful start-up of the anammox MBBR provides a reference for low nitrogen concentration wastewater treatment by anammox tecnology.
