  • 摘要: 建立潜流湿地有机污染物迁移转化模型，采用多孔介质模型描述潜流湿地的水力特性，并引入Monod方程相耦合，实现对湿地系统内部流场及水质浓度的同时模拟。通过实验，校核模型参数，并验证模型。结果表明，该模型能较好模拟潜流湿地中有机污染物的去除效果；计算条件下，在不同基质填料的潜流湿地中都会出现滞水区和快速通道，影响水力效率与污染物去除效果；预测了不同填料系统中7种典型选控性有机污染物的去除效果，其处理效率：苯胺 >苯酚 >二甲苯 >甲苯 >苯 >硝基苯 >氯苯，可通过优选填料提高吸附量和延长停留时间来提高选控性有机物的处理效果。
    Abstract: The transport and transformation model was established to represent organic pollutants flow patterns in subsurface flow wetland (SSFW).In order to simulate inside flow process and concentration in wetland system simultaneously,the porous media model coupled with Monod equation was introduced to describe the hydraulic characteristics and biodegradation.The parameters of model were tested and verified by a series of experiments.The result showed that this model could reasonably simulate the organic pollutants removal in SSFW.Theoretically,backwater section and fast channel would appear in different filler substrates in SSFW,which could influence the hydraulic efficiency and pollutant removal effects.Seven kinds of typical organic pollutants were selected,and the ranking of their removal efficiency was in the order of aminobenzene,phenol,dimethylbenzene,toluene,benzene,nitrobenzene and chlorobenzene.The treatment effects of selected control organic pollutants can be improved by extending the retention time and increasing adsorption quantity through further filler optimization.
