老龄垃圾渗滤液的厌氧氨氧化工艺研究

Study on ANAMMOX Process of Old Landfill Leachate

垃圾渗滤液处理面临的技术难点主要有两个:氨氮浓度高和难生物降解,若采用传统的硝化反硝化工艺处理则能耗大和成本高。本文着重综述了几种基于厌氧氨氧化技术处理垃圾渗滤液的新型方法,主要包括部分亚硝化-厌氧氨氧化(PN-ANAMMOX)耦合工艺、一体化部分亚硝化和厌氧氨氧化(CANON)工艺、和短程硝化反硝化-厌氧氨氧化联合工艺。

High ammonia concentration and poor biodegradability are two technical difficulties in landfill leachate treatment. Conventional nitrification and denitrification processes was widely used in landfill leachate treatment, but the energy consumption and cost were high. In this paper, several new methods for treating landfill leachate based on anaerobic ammonia oxidation technology are reviewed emphatically, including PN-ANAMMOX process, CANON process and Shortcut nitrification and denitrification-ANAMMOX process.
