摘　　要：人工湿地的广泛应用对工程设计提出了越来越高的要求,而人工湿地去污模型则是指导设计的基础.本文简要地介绍了若干典型的人工湿地去污模型,包括衰减模型、一级动力学模型、零级动力学模型、Monod模型和生态动力学模型等,比较分析了各种模型之间的关系,并给出了各模型微分方程的统一表达形式,该统一表达形式能将典型去污模型作为特例而概括.这一研究对人工湿地去污模型的深入研究具有指导意义.The widespread application of constructed wetlands for wastewater treatment requires better engineering design, thus more accurate pollutant removal models are needed. This paper comparatively studys some typical models, such as regression models, first-order models, zeroorder models, Monod-type models and complex dynamic compartmental models. Based on the analysis of the existing models, the generalized expression which could embrace the existing models as special cases is presented. This paper is significant to future studies on pollutant removal models for constructed wetlands.
