摘　　要：研究了上流式中试厌氧氨氧化(anaerobic ammonium oxidation,ANAMMOX)反应器在环境温度下的运行性能及其过程动力学特性.基质浓度试验表明,中试厌氧氨氧化反应器可在进水亚硝酸盐浓度为(380.4±18.3)mg.L-1稳定运行,继续提升至(480.5±21.9)mg.L-1时,反应器性能恶化.在水力停留时间(hydraulic retention time,HRT)试验中,HRT可缩短至3.43 h,反应器容积基质氮去除速率可达3.45 kg.(m3.d)-1.长期运行中,温度对中试厌氧氨氧化反应器的性能影响较大.采用改进型的Stover-Kincannon模型可较好地模拟非抑制状态下中试厌氧氨氧化反应器在不同温度范围下的行为.获得的Stover-Kincannon模型动力学参数及其出水总基质浓度预测公式和总基质去除率预测公式,可用于指导中试厌氧氨氧化反应器的实际操作.Performance and process biokinetics of the upflow pilot-scale anaerobic ammonium oxidation（ANAMMOX） reactor were investigated at ambient temperature.The results of substrate testing showed that the pilot-scale ANAMMOX reactor operated stably when the influent nitrite concentration reached（380.4 ± 18.3） mg.L^-1;while the nitrite inhibition occurred when its concentration arrived at（480.5 ± 21.9） mg.L^-1.The results of shortening of hydraulic retention time（HRT） showed that the HRT could be shortened to 3.43 h,and the nitrogen removal rate was as high as 3.45 kg.（m^3.d）-1.Temperature was found to affect the performance of the ANAMMOX reactor significantly during long-term operation.The modified Stover-Kincannon model was applied to model the non-inhibition performance of the pilot-scale reactor under different temperature ranges.Good fitting results were obtained.The process biokinetic parameters and effluent substrate concentration prediction equations as well as the substrate removal efficiency prediction equations obtained in different temperature ranges are helpful to the stable operation of the pilot-scale ANAMMOX bioreactor.
