厌氧氨氧化组合工艺处理老龄垃圾渗滤液工程研究
- Title:
- Treatment of Aged Landfill Leachate via Anammox Combined Process
- 摘要:
- 构建了一套前置反硝化-亚硝化-厌氧氨氧化脱氮系统,用于处理老龄垃圾渗滤液,整套系统启动历时151 d,处理量达到132 m3/d。将垃圾渗滤液与一级A/O出水按比例混合后进入反硝化反应器,去除垃圾渗滤液中的可生化有机物,以满足后续亚硝化与厌氧氨氧化反应器的进水水质要求;亚硝化反应器通过游离氨实现亚硝化后,控制进水负荷与曝气量使出水亚硝态氮与氨氮之比在1.1~1.4之间。通过控制出水浓度和多次补加菌种达到快速启动厌氧氨氧化的目的,满负荷运行期间厌氧氨氧化对总氮的平均去除率为73.3%,平均总氮去除负荷为0.74 kg/(m3·d)。与原有生化处理系统相比,该厌氧氨氧化系统节约了54.0%的能耗和82.6%的处理费用。
- Abstract:
- A nitrogen removal system, comprising pre?denitrification, partial nitrification, and Anammox, was established for the treatment of aged landfill leachate. The entire system was successfully commissioned over a period of 151 days, achieving a treatment capacity of 132 m3/d. The landfill leachate was proportionally mixed with the effluent from the primary A/O process before entering the denitrification reactor. This ensured that biodegradable organic matters in the landfill leachate were effectively removed, thereby meeting the influent quality requirements for subsequent partial nitrification and Anammox reactors. Following patrial nitrification via free ammonia, the ratio of nitrite nitrogen to ammonia nitrogen in the effluent could be maintained between 1.1 and 1.4 through precise control of the influent load and aeration intensity. The rapid start?up of the Anammox process was accomplished through precise control of effluent concentration and repeated inoculation of Anammox bacteria. During full?load operation, the average total nitrogen removal efficiency by Anammox was 73.3%, with an average total nitrogen removal load of 0.74 kg/(m3·d). Compared to the conventional biochemical treatment system, the Anammox system reduced energy consumption by 54.0% and lowered treatment costs by 82.6%.
