摘　　要：基于国内外现有研究,从不同工艺耦合形式的角度,对强化自养脱氮型人工湿地进行了分类。分析了工艺耦合方式及电子供体对脱氮路径的影响,阐明了工艺的研究现状和存在的问题。通过强化人工湿地中的自养脱氮作用,可提高人工湿地对低碳氮比污、废水的处理能力。认为通过工艺耦合与优化调控的方式,在传统人工湿地中强化自养脱氮作用,可有效提升人工湿地对不同碳氮比进水的抗冲击负荷及处理能力。虽然强化自养脱氮型人工湿地有诸多的问题尚待解决,仍是一种具有广泛研究价值的生态处理技术。The nitrogen removal efficiency of constructed wetland can be enhanced by autotrophic nitrogen removal for treating the low C/N wastewater.Based on the literatures,the process forms of the enhanced autotrophic nitrogen removal constructed wetland were classified.The synergy of process coupling and electron donors influence on the nitrogen removal pathway were analyzed,the current research status and existing problems of the process were clarified.It indicates that the enhancing the effect of autotrophic nitrogen removal in constructed wetlands through process coupling and optimized operation can effectively improve the treatment capacity and impact load for different C/N wastewater treatment.The potential of the enhanced autotrophic constructed wetland is quite promising despite a few unsolved issues.
