摘　　要：垃圾渗滤液有着氨氮浓度大、碳氮比小、组成成分复杂、水质变化大、有机物质含量丰富、色度高等特点。厌氧氨氧化目前是一种新型的深度除氮技术,具有需要碳源少、氧消耗量低、污泥产量小等特点。重点介绍了几种厌氧氨氧化为基础的处理垃圾渗滤液废水的新型深度脱氮工艺,主要包括分体式短程硝化厌氧氨氧化(SHARON-ANAMMOX)工艺、一体化部分亚硝化厌氧氨氧化(CANON)工艺、一体式限氧自养硝化厌氧反硝化(OLAND)工艺。Landfill leachate has the characteristics of high ammonia nitrogen concentration,low carbon nitrogen ratio,complex components,large changes in water quality,rich organic matter content and high chromaticity.ANAMMOX is a new type of deep nitrogen removal technology,which has the characteristics of less carbon source,low oxygen consumption and small sludge output.In this paper,several new advanced nitrogen removal processes for the treatment of landfill leachate wastewater based on anaerobic ammonia oxidation were introduced,mainly including split shortcut nitrification anaerobic ammonia oxidation(SHARON-ANAMMOX)process,integrated partial nitrification anaerobic ammonia oxidation(CANON)process and integrated oxygen limited autotrophic nitrification anaerobic denitrification(OLAND)process.
