摘要: 为从厌氧序批式反应器中接种好氧硝化污泥,对厌氧氨氧化污泥的培养进行了研无采用含氮模拟废水,在进水pH值为7.2~7.8、温度为(30±1)℃的条件下运行142d,成功培养出厌氧氨氧化污泥.实验结果表明:在水力停留时间为1.2d、总氮容积负荷(以N计)为0.4318ks/(m3 ·d)时,总氮去除率最高达到93.3% ,平均为80.5% ;氨氮和亚硝酸盐氮的去除率最高达到93.9%和99.8% ,平均为81.2%和85.7% ;氨氮和亚硝酸盐氮去除的比例(摩尔比)为1:(1.387±0.024),反应器内主要发生厌养氨氧化反应,说明采用厌氧序批式反应器是培养厌氧氨氧化污泥的一条途经.

Abstract:

In order to seed aerobic nitrated sludge in an anaerobic sequencing batch reactor(ASBR),the anaero-bic ammonium-oxidized sludge(ANAMMOX)was successfully enriched at(30±1)oC after a 1 42-day cultivation,with the influent pH value ranging from 7.2 to 7.8.Experimental results indicate that,with a hydraulic settling time of 1.2d and a volumetric loading rate(calculated with the content of N)of 0.431 8 kg/(m3 ·d),the maxi-mum and average removals of the total nitrogen respectively achieve 93.3% and 80.5% .while the maximum re-movals of NH4+-N and NO2--N respectively achieve 93.9% and 99.8% .averaging 81.2% and 85.7% respective-ly.In addition,the mole ratio of the removed NH4+-N to the removed NO2--N in the ANAMMOX process is 1:(1.387±0.024),and the anaerobic ammonium oxidation is found to be the main reaction in the ASBR,which means that ASBR is one of the useful tools to enrich the ANAMMOX sludge.
