dc.description.abstract水污染防治工作在國內外皆為一重要的議題,近年來臺灣地區屢屢發 生重大水污染事件,破壞生活周遭的水環境,進而污染河川流域的水體水 質,因此水污染防治法第一條即說明「為防治水污染,確保水資源之清潔, 以維護生態體系,改善生活環境,增進國民健康,特制定本法」,顯示出 水污染防治工作的重要性。 有鑑於此,本研究以霄裡溪流域為例,運用QUAL2K 水質模式進行模擬 河川之污染量及涵容能力,本研究率定及驗證結果,以MAPE 進行檢核,其 範圍介於1.1%〜50%之間,證明QUAL2K 適用於模擬霄裡溪流域之污染量及 涵容能力,經模擬後生化需氧量及氨氮之污染量分別為278.4kg/d 及 45.4kg/d,而生化需氧量及氨氮之涵容能力分別為79.4kg/d 及7.4kg/d, 需分別削減生化需氧量278.4kg/d 及氨氮45.4kg/d,方使霄裡溪流域符合 甲類水體水質。 本研究針對污染量的削減,提出六個總量管理策略進行污染量的削 減,其中以「畜牧糞尿沼液沼渣作為農地肥分使用」之改善效果最佳,可 完全削減污染項目並保有餘裕量,另外可同時執行幾個不同的管理策略並 以最經濟的管理策略進行改善水體水質。zh_TW
dc.description.abstractThere have been frequent sever water pollution which affect the water quality nearby in urban areas and river basins in recent years. As a result, the first article of Water Pollution Control Act was enacted with the purpose to prevent water pollution, to remediate the polluted water body, to ensure the quality of water resources, and to protect the ecology. The purpose of this work is to develop management strategy based on water quality model, QUAL2K using a case study, Xiaoli Creek, Hsinchu. QUAL2K is employed to simulate the amount of pollution and the capacity for pollution. Estimation of the amount of pollutants is made by analyzing the data from long-term water quality monitoring from both EPA and local government so as to understand the level of pollution in Xiaoli Creek basin. After fieldwork and sampling, the decrement of pollutant in Xiaoli Creek basin can be calculated by the laws of water quality model. The modeling result is confirmed by MAPE, ranging from 1.1% to 50% which proved the credibility of applying QUAL2K to simulate the quantity of pollution and assimilative capacity in Xiaoli Creek basin. The outcome from the simulation indicated that biochemical oxygen demand (BOD) and ammonia nitrogen (NH3-N) are 278.4kg/d and 45.4kg/d, respectively. Meanwhile, the assimilative capacity of BOD and ammonia nitrogen are 79.4kg/d and 7.4kg/d, respectively. The results require 278.4kg/d deduction in assimilative capacity and 45.5 kg/d in ammonia nitrogen for Xiaoli Creek to meet the water body quality of classification A. The study brought up six strategies of total amount management in quantity of pollution deduction. The most effective solution is utilization of faeces from livestock as fertilizer to the farm. The strategy is able to eliminate pollutants without any compromises. On the other hand, executing multiple strategies enables us to find out the most economical combination to improve the water body.en_US
