| 中文摘要 | 南崁溪的舊名是「青溪」,是桃園市境內重要的河川之一,南崁溪流域面積約214.6平方公里,主流全長30.73公里,南崁溪沿岸的居民更高達78餘萬人,隨著桃園市工業的迅速發展,都市化程度增加,沿岸產生之生活污水、工業廢水及畜牧污水大量排放至南崁溪中,造成河川污染負荷急遽增加,導致部分河段呈現嚴重污染情形,為整治河川流域改善水體水質,有效控制污染源進入河川水體是最有效的辦法,此外,污(廢)水是否經妥善處理會影響溫室氣體排放量,故用戶接管率提升除有助於水質改善外,亦有助於減少生活污水溫室氣體排放量。本研究使用WASP水質模式對桃園市境內南崁溪進行河川水質模擬,透過模擬污水下水道建設之短期(2026年)、中期(2032年)、長期(2038年)對河川水質改善成效,及用戶接管提升對廢水處理能耗及溫室氣體排放變化之分析。隨著污水下水道用戶接管普及率逐年提高,南崁溪於大檜溪橋在2032年後因用戶接管普及率上升,其水質情況由嚴重污染程度下降至中度污染。另本研究推估結果顯示,在南崁溪流域內之用戶接管普及率於2021年31.3%提高至2038年64.5%的狀況下,南崁溪流域之溫室氣體排放量自67.22 ktCO_2e下降至26.01 ktCO_2e,除可減緩溫室氣體造成之全球暖化效應,亦將助於我國2050年邁向淨零排放之長期願景。 |
| 英文摘要 | The Nankan River, formerly known as the Qingxi Stream, is one of the important rivers in Taoyuan City. The Nankan River basin covers an area of 214.6 square kilometers, with the river itself extending 30.73 kilometers. More than 600,000 residents live along the banks of the Nankan River. Due to the rapid development of industry and urbanization in Taoyuan City, sewage, including domestic sewage, industrial wastewater, and livestock wastewater, is discharged into the Nankan River. As a result, pollution levels in the river have been rising rapidly, with certain sections classified as severely polluted. To improve the water quality of the river, controlling pollution sources and reducing the amount of pollution discharged into the river are essential measures. Furthermore, proper treatment of sewage also helps reduce greenhouse gas emissions. Along the Nankan River, as the sewage treatment rate increases with sewer construction, greenhouse gas emissions from domestic sewage will decrease. This study uses the Water Quality Analysis Simulation Program (WASP) model to simulate the water quality of the Nankan River in Taoyuan City and examines the short, medium, and long-term effects of sewer construction on water quality improvement and greenhouse gas emissions. After 2032, due to expected increases in household connection rates, the river pollution index at the Dakuaixi Bridge monitoring station on the Nankan River is expected to improve from severely polluted to moderately polluted. Greenhouse gas emissions in the Nankan River basin are projected to decrease from 67.22 ktCO_2e to 26.01 ktCO_2e as the sewage treatment rate increases from 31.7% in 2021 to 64.4% in 2038. Increasing the sewage treatment rate will mitigate the greenhouse effect and support Taiwan's long-term goal of achieving net zero emissions by 2050. |
