台灣土地地狹人稠，隨著與日俱增的垃圾量，儼然成為了各縣市政府迫切處理的議題，但因掩埋場存在著場地及容量限制，使得政府選擇焚化做為廢棄物處理的主要手段。都市廢棄物焚化廠（Municipal solid waste incinerator, MSWI）雖被證明為一種快速且商業化的固體廢棄物處理技術，亦是現代常用以處理廢棄物的方式；但衍生空氣污染議題持續受到人們關注。焚化爐使用過程將產生戴奧辛及呋喃、氮氧化物、硫氧化物及氯化氫等持久性有機污染物(Persistent organic pollutants, POPs)，其戴奧辛及呋喃又具有生物累積性、自然分解困難、環境與生物毒性以及長距離傳輸等特性。
因此本研究欲探討屏東市大型焚化爐之煙道排放監測，瞭解焚化爐在營運強況下之環境大氣中戴奧辛濃度。同時調查計畫期間焚化廠燃燒排放戴奧辛及呋喃焚化爐之其他因子對戴奧辛及呋喃之影響程度及對屏東市地區大氣之影響。
經蒐集相關資料分析，焚化爐之戴奧辛平均排放濃度由100年至之0.024 ng I-TEQ/Nm3至110年之0.086 ng I-TEQ/Nm3，其中分析戴奧辛17種同係物顯示OCDD為主要貢獻、OCDF為其次；分析廢棄物組成顯示含碳及氯元素為主要成份，符合戴奧辛組成需求；另針對屏東市地區大氣戴奧辛濃度與焚化爐排放戴奧辛比較，其濃度趨勢與焚化爐煙道排放之變化趨勢相近。

In Taiwan is narrow and densely populated. With the ever-increasing amount of garbage, it has become an urgent issue for the county and city governments. However, due to the limited space and capacity of landfills, the government chooses incineration as the main method of waste disposal. Although Municipal solid waste incinerator (MSWI) has been proven to be efficient and commercial solid waste treatment technology, and it is also a commonly used method of waste disposal in modern times, the issue of derived air pollution continues to receive attention. The use of the incinerator will produce persistent organic pollutants (POPs) such as dioxin and furan, nitrogen oxides, sulfur oxides and hydrogen chloride. properties such as toxicity and long-distance transmission.
Therefore, this study aims to investigate the flue emission monitoring of large-scale incinerators in Pingtung City, and to understand the concentration of dioxin in the surrounding atmosphere of the incinerator under operating conditions. At the same time, investigate the impact of other factors of dioxin/furan in the incineration plant combustion on dioxin/furan and the atmosphere in Pingtung City during the project period, so as to provide control measures for the reference of the operating and supervisory units, and gradually complete the relevant information of the collection.
After collecting and analyzing relevant data, the average emission concentration of dioxin from incinerators ranges from 0.024 ng I-TEQ/Nm3 to 0.086 ng I-TEQ/Nm3 from 2001 to 2021, among which the analysis of 17 congeners of dioxin shows that OCDD is the main contribution OCDF is the second; analysis of waste composition shows that carbon and chlorine are the main components, which meet the composition requirements of dioxin; in addition, the concentration of dioxin in the atmosphere of Pingtung City is compared with the emission of dioxin from incinerators. The trend of change is similar.
