摘　　要：对比研究了2种UASB-厌氧氨氧化反应器的启动。采用2个15L UASB反应器A、B，A添加海绵填料，B无填料，在温度为（33±2）℃，进水pH为6．5～7．5的条件下启动反应器。结果表明，2个反应器均经历了适应期、提高期和稳定期3个阶段，A反应器在80d进入稳定期，氨氮和亚硝氮去除率达99．8％和99．9％，B反应器在105d进入稳定期，氨氮和亚硝氮去除率达98．1％和98．9％。A反应器污泥为褐色，并有红色颗粒污泥，B反应器污泥颜色为深褐色。The starting-up ofupflow anaerobic sludge blanket （UASB）-anaerobic ammonium oxidation（ANAMMOX） process has been investigated comparatively in two 15 L UASB reactors. To Reactor A, sponge filler is added and to Reactor B, no filler is added. When the temperature is （33±2） ℃ and influent water pH 6.5-7.5, the reactors can be started up. The results show that these two reactors have undergone three stages ： adaptation period, improving period and stabilizing period. The removing rates of NH4^＋-N and NO2--N are 99.8% and 99.9%, respectively, when Reactor A goes to stabilizing period in 80 d. The removing rates of NH4^＋--N and NO2--N reach 98.1% and 98.9% , respectively ,when Reactor B goes to stabilizing period in 105 d. The sludge color in Reactor A is brown ,with small red particles and the sludge in Reactor B is dark brown.
