摘　　要：碳源不足已成为限制人工湿地脱氮的重要因素,植物材料因其经济易得、安全有效的特点,被广泛用作人工湿地脱氮的外加碳源。文章从天然植物材料的处理、利用方式、脱氮效果等方面研究了其作为人工湿地外加碳源的脱氮机理和脱氮效果,为提高人工湿地脱氮效率提供科学依据及建议。最后,归纳了该研究存在的主要问题,并对今后的发展方向进行了展望。Nitrogen removal in the constructed wetland was mainly restricted by the insufficient carbon source.Plant materials were utilized as the additional carbon sources in nitrogen removal of the constructed wetland,considering its economic,available,safe and effective properties.This paper mainly studied the denitrification mechanism and the effect of the natural plant materials as the additional carbon sources in the constructed wetland from the aspects of treatment,utilization mode and denitrification effect,and provided scientific basis and suggestions to improve the nitrogen removal.Finally,the main problems existing in the research field were concluded and the development trends were prospected.
