摘　　要：采用自制的UASB(升流式厌氧污泥床)反应器,接种产甲烷颗粒污泥,以自配含有氨氮和亚硝态氮的水为进水,来研究厌氧氨氧化反应的启动和影响因素。实验结果表明:反应器运行150后,氨氮(NH_(4)^(+)-N)和亚硝态氮(NO_(2)^(-)-N)的去除率稳定在50%左右,硝态氮(NO_(3)^(-)-N)有明显增加,表明厌氧氨氧化反应启动成功;在温度为30~35℃,pH为7~7.5,水力停留时间为24 h,COD为100~200 mg/L,NH+4为89.3 mg/L,NO_(2)^(-)为100 mg/L,即NH_(4)^(+):NO_(2)^(-)=1:1.12时,厌氧氨氧化反应速率最快。Methane-producing granular sludge was vaccinated in UASB(Upflow Anaerobic Sludge Blanket)reactor.The water which contained ammonia nitrogen and nitrite was taken as influent,anammox reactor startup and influencing factors were studied.The experimental results showed that after 150 days of the reactor operation,removal rate of was NH_(4)^(+) and NO_(2)^(-) up to about 50%,NO_(3)^(+) increased significantly,which showed anaerobic ammonium oxidation reaction start-up successful.In the temperature of 30~35℃,pH for 7~7.5,hydraulic retention time for 24 h,COD for 100~200 mg/L,NH_(4)^(+) for 89.3 mg/L,NO_(2)^(-) for 100 mg/L,namely NH_(4)^(+):NO_(2)^(-)=1:1.12,anammox had the fastest reaction rate.
