  • 摘要: 生态修复法常用于尾水生态河道的修复，不同的净化单元需要合理搭配才能获得最优的处理效果.本研究应用QUAL2K水质模型建立了针对某污水处理厂尾水河道的数值模型，进而筛选出最优的生态净化单元，并确定了单元所需的停留时间和布置密度.通过数值模拟得到布置密度、停留时间与水质达标等级的定量关系，可为今后进行设计方案优选和工程升级改造提供参考和支撑.
    Abstract: Ecological restoration method is commonly used in the restoration of the treated water, and different purification units need to be matched well to get the most effective treatment. In this study, QUAL2K model was applied to the treated water channel in a wastewater treatment plant, and the optimal ecological purification unit was selected. Meanwhile, the density of the layout and the residence time for purification units was calculated. Through the numerical simulation, quantitative relationship among the density of the layout, the residence time and the grade of the water quality were obtained. This study can provide a reference for the optimization of the design scheme and the upgrading of the project in the future.
