計畫中文摘要	台灣受油品污染場址眾多，除了各縣市加油站及儲油槽可能造成之洩漏外，煉油廠之油品污染場址亦需要花費巨大整治量能；部分油品具有揮發性，整治過程中會形成氣體逸散至大氣中，造成空氣污染及溫室氣體排放。其中又以土地農耕法與化學氧化法屬戶外開放空間之整治法需額外關注。因此，本研究依上述三種整治方法為構想，以整治工法之操作內容，設計為田口式實驗法L8 直交表之因子，探討受柴油品污染土壤VOCs逸散。此外，亦進行污染場址現場量測，計算CO2及VOCs排放量及探討其逸散特性。 田口實驗針對VOCs逸散濃度之品質特性望大分析顯示，各因子對於VOCs 逸散之影響程度依序為:柴油濃度、含水率、灑水次數、翻土次數、灑水與翻土順序、土壤質地及氧化劑添加。實場研究結果顯示，VOCs 逸散濃度受溫度影響程度大於CO2，且土壤含水率較低之土壤，其溫度影響越顯著。其土壤經過翻動後之一小時內，CO2 逸散濃度相較於VOCs較穩定，VOCs逸散濃度下降率約為30-40%，而 CO2 則可維持初始值之濃度。依上述等研究成果，給予整治單位相關建議，以提升整治過程空氣污之染物逸散之控制成效。
計畫英文摘要	There are numerous oil-contaminated sites in Taiwan, where not only gas stations and storage tanks in various counties may cause leaks, but also oil refineries require significant remediation efforts. Some oil products are volatile, and during the remediation process, gases can escape into the atmosphere, leading to air pollution and greenhouse gas emissions. Among the remediation methods, land farming, and chemical oxidation are outdoor methods that require additional attention. Therefore, this study is designed based on the aforementioned three remediation methods, employing a Taguchi L8 orthogonal array experimental design to investigate the VOCs emissions from dieselcontaminated soil. Additionally, on-site measurements of contaminated sites are conducted to calculate CO2 and VOCs emissions and to explore their dispersion characteristics. The Taguchi experiment analysis of the quality characteristics regarding VOCs emissions shows that the influencing factors, in order of significance, are: diesel concentration, moisture content, frequency of watering, frequency of tilling, the sequence of watering and tilling, soil texture, and the addition of oxidants. Field study results indicate that the impact of temperature on VOCs emissions is greater than that on CO2, and that for soils with lower moisture content, the temperature effect is more pronounced. Within one hour after tilling the soil, the CO2 emissions are more stable compared to VOCs, with a decrease rate of VOCs emissions of approximately 30-40%, while CO2 can maintain its initial concentration. Based on these research findings, recommendations are provided to remediation units to enhance the control of air pollutant emissions during the remediation process.
