摘要:
以某垃圾填埋场老龄垃圾渗滤液为处理对象，构建了一套前置亚硝化反硝化-部分亚硝化（PN）/厌氧氨氧化（A）工艺的中试系统，探究其对该老龄垃圾渗滤液低碳脱氮处理的快速启动与适用性。结果表明，在已有培养成熟的厌氧氨氧化菌种基础上，该中试系统仅用23 d就达到了15 kg/d的氨氮去除量；通过前置反硝化去除渗滤液中的大部分可生化有机物后，系统对老龄垃圾渗滤液中氨氮、总氮和COD的平均去除率分别可达到95.1%、94.3%、67.9%；经济核算结果表明，该工艺的处理成本（以去除NH4+-N计）仅为9.3 元/kg，远低于硝化-反硝化工艺。
Abstract:
This paper constructed a pilot-scale system consisting of pre-nitritation/denitrification, partial nitritation (PN) and Anammox (A), and investigated its rapid start-up and applicability for removing nitrogen in the aged landfill leachate with low organic pollutants concentration from a landfill. Seeded with existing mature Anammox bacteria, the pilot system achieved a removal of 15 kg/d ammonia nitrogen in just 23 days. After pre-denitrification to remove most of the biodegradable organic pollutants in the leachate, the average removal rates of ammonia nitrogen, total nitrogen, and COD from the aged landfill leachate reached 95.1%, 94.3% and 67.9% respectively. The economic calculations showed that the treatment cost of this process was only 9.3 yuan/kg, which was significantly lower than that of the nitrification-denitrification process.
