| 摘 要： | 水动力过程是湿地净化功能发挥的重要机制之一.根据脉冲示踪试验,获得潜流人工湿地的水力停留时间分布曲线.针对其"多峰"现象,利用数学软件MATLAB7.0分别将对数正态分布、对流扩散模型以及考虑延迟的连续完全混合反应器模型时脉冲示踪试验数据进行叠加模拟,同时利用多流弥散模型拟合分析,结果表明:叠加模型和多流弥散模型均能较...

| Abstract: | Hydrodynamics of the constructed wetlands is an important mechanism affecting its treatment performance.Instantaneously injected sodium chloride tracers were used to obtain residence time distributions in 4 parallel inhomogeneous gravel cells of the subsurface flow constructed wetland.Considering the presence of multiple peaks,the combined models including logarithm normal distribution,dispersion and plug flow model(DPFM) and the completely stirred tank reactor model(CSTRM) and multiflow dispersion model(MF... |
