【摘要】: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、p H 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NH_4~+-N、NO_2~--N及TN出水平均质量浓度分别为1.5、1及10 mg/L,NH_4~-+N、NO_2~--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NO_2~--N的去除速率逐渐降低,NH_4~+-N的去除表现出明显的滞后性.
