摘要:
提出了一种耦合前置反硝化的一体式短程硝化-厌氧氨氧化（DN-PN/A）工艺，并用于处理垃圾填埋场综合废水，重点考察了该工艺的脱氮效能及机理。结果表明，DN-PN/A工艺对TN的去除率和去除负荷可稳定达到95%和0.40 kg/（m3·d）左右，出水TN浓度可稳定在40 mg/L以下，出水水质符合《生活垃圾填埋场污染控制标准》（GB 16889—2008）。碳和氮去除贡献分析及微生物分析表明，前置反硝化主要实现COD的去除，提高回流比可有效促进其反硝化作用，减少进水COD对PN/A反应器的影响，保障PN/A反应器中厌氧氨氧化稳定运行的同时，有效提高DN-PN/A耦合工艺的TN和COD去除率；PN/A反应器主要实现高效生物脱氮，通过氨氧化菌（Nitrosomonas和Ellin6067）和厌氧氨氧化菌（Candidatus_Kuenenia）的协同作用实现TN的稳定高效去除。
Abstract:
An integrated partial nitritation-anaerobic ammonium oxidation process combined with pre-denitrification (DN-PN/A) was developed and applied to the treatment of wastewater in a landfill. The nitrogen removal efficiency and underlying mechanisms of the DN-PN/A process were systematically investigated. The TN removal efficiency and removal load achieved by the DN-PN/A process stably reached approximately 95% and 0.40 kg/(m3·d), respectively. The effluent TN remained consistently below 40 mg/L, meeting the requirements specified in Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889-2008). Analysis of carbon and nitrogen removal performance, as well as microbial community composition, indicated that the pre?denitrification primarily contributed to COD removal. Increasing the reflux ratio could effectively enhance the denitrification process, mitigate the impact of influent COD on the PN/A reactor, and ensure the stable operation of the anaerobic ammonium oxidation reaction within the PN/A reactor. This improvement led to higher removal efficiencies of both TN and COD in the DN-PN/A system. The PN/A reactor mainly facilitated efficient biological nitrogen removal through the synergistic activity of ammonia-oxidizing bacteria (such as Nitrosomonas and Ellin6067) and anaerobic ammonium?oxidizing bacteria (Candidatus_Kuenenia), thereby achieving stable and effective TN removal.
