摘　　要：城市污水厂尾水等低碳氮比污水的深度脱氮普遍面临碳源不足的难题,人工湿地耦合天然纤维素类生物质碳源以高效益、低成本的经济环境优势得到了广泛的关注和研究。列举了常见的生物质碳源,主要包括秸秆类、壳类、玉米芯、甘蔗渣等农业废弃物及花卉秸秆、芦苇、香根草、杨树叶、梧桐树叶、广玉兰树叶等园林凋落物。总结比较其材料特性、运行效果、优势及弊端等研究现状,并对其在人工湿地中的应用存在的技术问题进行分析展望。The deep denitrification of waste water in low carbon to nitrogen ratio such as sewage plant effluent generally has the problem of insufficient carbon source.Constructed wetlands coupling biomass carbon source such as natural cellulose has received extensive attention with high-efficiency and low-cost economic environment advantages.This paper enumerates the common biomass carbon sources,including agricultural wastes such as straw,shell,corn cob,bagasse and garden litter such as flower stalks,reeds,vetiver grass,poplar leaves,phoenix leaves,and magnolia leaves.It summarizes the research status of material properties,operation effect,advantages and disadvantages,and analyzes the technical problems existing in the application of natural cellulose in constructed wetlands.
