| 摘 要： | 以湖北漳河灌区的水塘湿地为研究对象,用罗丹明作示踪剂,通过示踪试验来测定湿地水力停留时间分布、了解水力停留时间的性质,并分析影响水力停留时间的因素,为灌区水塘湿地的改造和净化能力的提高提出合理的建议。

| Abstract: | A pond wetland,located in Group 2 of Shuangbei village in Zhanghe Irrigation System was selected for the study of HRT through Rhodamine tracer experiment.The Rhodamine concentration-time distribution showed the actual retention time(1.11 h) is much smaller than nominal detention time(32 h),and the actual flow pattern is between the plug flow and continuous stirred flow based on the characteristic value of hydraulic residence time distribution.The reasons for the smaller actual retention time have been analy... |
