摘　　要：采用1套有效容积为3 L的厌氧复合床作为厌氧氨氧化反应器,用提高进水基质浓度和缩短反应器水力停留时间2种方式提高反应器的容积负荷,进而研究反应器最佳的进水浓度和水力停留时间。结果表明,在HRT为24 h的条件下,反应器最佳进水浓度NH4+-N与NO2--N在110 mg/L左右;通过调节HRT发现,当HRT大于8 h时,NH4+-N与NO2--N的去除率都在80%以上。The anaerobic ammonium oxidation（ANAMMOX）reactor is a upflow blanket filter（UBF）with an effective volume of 3 L.This paper describes two ways to improve the volume loading of the reactor,which can improve the influent substrate concentration and shorten the hydraulic retention time（HRT）,and also discusses the best influent concentration and HRT of the reactor.The results showed that when the HRT was 24 h,the influent concentration of NH4^＋-N and NO2^--N reached the best value of about 110 mg/L.After adjusting the HRT,the removal rate of NH4^＋-N and NO2^--N changed,when the HRT was longer than 8 h,they were all above 80%.
