摘要
针对人工湿地的设计问题,介绍了水平潜流人工湿地的运行机制和设计准则,提出了利用人工湿地数字模型Subwet辅助设计的方法.利用Subwet模型对水平潜流人工湿地的设计进行了模拟,根据模拟结果对影响人工湿地处理效率的因素进行了分析和探讨,并据此对人工湿地的设计优化提出了指导意见.该Subwet模型的应用实例表明人工湿地模型可以应用于设计中,并可为人工湿地设计提供一定的理论指导.
The mechanism of horizontal subsurface-flow constructed wetland （HSSF CW） and its design guidelines were introduced for the design of a constructed wetland. A numerical model Subwet was proposed to aid the design of constructed wetland. The design of a horizontal subsurface-flow wetland was simulated by utilizing Subwet model. The treatment efficiency for a year round operation was obtained from the modelling. The factors which have effects on treatment efficiencies were analyzed and investigated in this study. The recommendations on optimizing and improving the HSSF CW design were provided. This case study of Subwet model demonstrated the applicability of this model in the design of constructed wetland. It can provide theoretical basis for the design of constructed wetland.
