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NH_4~+-N与NO_2~--N在110 mg/L左右;通过调节HRT发现,当HRT大于8 h时,NH_4~+-N与NO_2~--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 in-fluent concentration of NH_4~+ -N and NO_2~- -N reached the best value of about 110 mg/L. After adjusting the HRT, the removal rate of NH_4~+ -N and NO_2~- -N changed, when the HRT was longer than 8 h, they were all above 80% .
