論文中文摘要:人工溼地系統是屬於自然淨化系統之一,在現有各種類型的生態工程中,人工溼地處理技術因具有低成本、低耗能源、無二次污染物之產生,且提供溼地生態與景觀等優點。在水庫集水區污水處理廠無法全面有效管理廢污水的情況下,可提供不錯之代替選擇方案,以達水質改善之目標。
本研究以翡翠水庫管理局於2005年在北勢溪上游渡南橋旁所建置之自然淨化系統-人工溼地系統為例,該系統設置主要串連不同單元之生態溼地,以處理該集水區內之非點源污染與地面逕流,將營養物質滯留於系統內而降低污染物質流入水庫。本研究場址應用不同之淨化效率分析方法,針對本研究場址之除污效率進行探討分析,無論降雨或晴天,顯示本系統對於總磷及氨氮削減率以中位數處理效率53.89%及73.91%,累積負荷法(SOL)為83.96%及68.85%,事件平均濃度法(EMC)57.34%及64.60%,均有相當的處理成效。總磷在降雨時期之淨化效果較晴天時顯著,而氨氮受到水溫及入流濃度偏低之影響,在晴天之污染去除效率反而高於降雨期間去除效率。
本研究利用不同之淨化效率分析方法,藉由評估成果回饋修正原有設計、施工乃至操作維護管理之合宜性,並可建立適合本土性設計參數及區域性自然淨化工法設計資料庫,有助於國內其他水庫水質管理技術之參考。
論文英文摘要:The constructed wetland system, one of the natural treatment systems (NTS), possesses several advantages in many aspects, such as low cost, low energy consumption and no secondary pollutants; it also has advantages in the wetland ecology and landscape. It can provide a superior alternative to improve the water quality when the wastewater treatment plants in the watershed cannot effectively dispose the waste water.
The research is a case study of a combined constructed wetlands system, which was built on the side of near Donan Bridge and located on the bank of Peishih Creek by Taipei Feitsui Reservoir Administration in 2005. The systems that were considered to link the various units of ecological wetlands have dealt with NPS of the rainfall and surface runoff of the watershed in which the surrounding nutrition is remained on the system to decrease the pollutants flow to the reservoir. The study is to research purification efficiency using different kinds of analytical method from the time of the system was set up to the present. No matter rainy or sunny, The median value processing efficiencies of the total phosphorus and the ammonia nitrogen in the system are 53.89% and 73.91%, Summation of Loads method (SOL)are 83.96% and 68.85%, Event Mean Concentration method (EMC)are 57.34% and 64.60%, The research also shows that the removal efficiency of TP is more significant in rainy period, while the efficiency of the elimination of NH3 is higher in a sunny day than the rainy period due to the influence from the lower water temperature and inflow concentration.
The research applies various analysis methods to modify the original design and construction, even maintenance feasibility by using the feedback from the results. It also helps build up the domestic design parameters and the design database for local natural treatment methods as a reference for the other reservoirs in Taiwan.
