碩士 / 逢甲大學 / 水利工程與資源保育研究所 / 98 / Constructed wetlands were widely applied for water purification, ecosystem and landscape rehabilitation, flood mitigation and so on. Urban sewer systems are planning and constructing, hence properly designed, constructed, maintained and managed wetlands can provide very efficient treatment of animal wastewater. Accordingly, constructed wetlands for removing contaminants are frequently established at floodplain or upland within stream corridor; and water quality improvement throughout overland flows and vegetations is significant. No matter which kind of wetlands would be surely functioned well, two main methodologies are necessary to study: hydrology-driven approach and ecology-driven approach. The ecosystem could be a sign for wetlands’ healthy, and also be an important disturbance factor for hydrology-driven regime in constructed wetlands. Besides, hydraulic efficiency of treatment constructed wetlands is an important factor. This study applies tracer test to analyze hydraulic retention time and short-circuiting which could be an important reference for maintenance and improvement of constructed wetlands.Furthermore, SMS model is adopted to simulate the dead-zone, flow field and improvement from modification.
