%X 为研究折流板生物膜反应器快速启动厌氧氨氧化的可行性，在温度（30±2）℃、DO 0.2~0.5 mg/L、pH 7.6~8.0，平均进水氨氮、亚硝氮负荷分别为0.12和0.18 kg/（m3·d）的条件下，采用低负荷连续进水的方式，启动厌氧氨氧化反应器.经83 d的连续运行，启动成功.成功启动后NH4+-N、NO2--N及TN出水平均质量浓度分别为1.5、1及10 mg/L，NH4+-N、NO2--N的去除率达95%以上，TN去除率达80%以上，出水氮素达到《城镇污水处理厂污染物综合排放标准》（GB18918-2002）一级A标准要求.稳定运行阶段，反应器沿程各单元格中NO2--N的去除速率逐渐降低，NH4+-N的去除表现出明显的滞后性.</br>In order to evaluate the feasibility of the fast startup of Anammox process, a lab-scale Anammox baffled biofilm reactor was carried out in this study. The experimental conditions were maintained at temperature (30±2)℃, DO 0.2-0.5 mg/L, pH 7.6-8.0, average ammonia nitrogen load at 0.12 kg/(m3·d) and nitrite nitrogen load at 0.18 kg/(m3·d), respectively. By taking continuous low strength influent, the start-up process was successfully achieved within 83 days. After the fast startup, the average concentration of effluent NH4+ -N, NO2--N and TN were 1.5, 1 and 10 mg/L, respectively. Meanwhile, the average removal efficiencies of NH4+ -N, NO2--N and TN reached 95%, 95% and 80%, respectively. The effluent could stably meet the first grade A standards of Urban Sewage Disposal Plant Contamination Integrated Discharge Standard of China (GB 18918-2002). Under the stable phase, the removal rate of NO2--N in each compartment along the reactor gradually decreased, and the remove of NH4+ -N presented in some delay.
