摘要

进行了厌氧氨氧化固定床反应器的运行性能试验，分析了其过程动力学特性。接种反硝化污泥，用模拟废水可成功启动该反应器。当进水总氮浓度为608 mg·L-1，水力停留时间为2 h，总氮负荷为7.34 kg·m-3·d-1时，反应器获得最大基质去除速率6.11 kg·m-3·d-1。二级动力学模型和改进的StoverKincannon模型均适用于非基质抑制状态下的厌氧氨氧化反应器过程模拟。StoverKincannon模型动力学分析表明，这种反应器的最大基质去除速率可达12.4 kg·m-3·d-1，具有较大的脱氮潜能。

Abstract

The performance of an ANAMMOX(anaerobic ammonium oxidation) fixed-bed reactor was tested and the process kinetics characteristics of the reactor was analyzedThe ANAMMOX reactor was successfully operated within 86 days with denitrifying activated sludge as inoculumWhen operated at a hydraulic retention time of 2 h and influent total nitrogen of 608 mg·L-1

corresponding to a nitrogen loading rate of 7.34 kg·m-3·d-1

the maximum total substrate removal rate of 6.11 kg·m-3·d-1 was observedSecondorder and a modified StoverKincannon models well fitted the ANAMMOX fixed reactor under the substrate noninhibition conditionsThe maximum total substrate removal rate achieved in this study was still far lower than the theoretical value 12.4 kg·m-3·d-1 deduced from the Stover Kincannon model

which indicated great potential in improving reactor performance.
