計畫中文摘要	受有機物污染之土壤可採用(1)土壤氣體抽取法(Soil Vapor Extraction, SVE)、(2) 生物通氣法、(3)加熱脫附法、(4)空氣注入法(Air Sparging, AS)、(5)化學氧化法及(6)雙向抽除法(Dual-phase Extraction, DPH)等，前述處理方法對於清除條件亦有受限，而本研究所提出之微波電漿(Microwave plasma)透過磁控管(Magnetron)產生微波源，於常溫環境下產生高能量電子，相比起其他電漿源，微波電漿的氣體解離率及電漿密度、操作壓力範圍廣、快速且均勻地加熱、操作時不需使用電極等優點，微波電漿整體處理過程相較其他技術而言，其不會產生二次污染物，且處理成本相較熱處理法來的低。 因此，本研究建置一套微波電漿系統設備，針對受有機物污染之土壤進行試驗，以室外土壤為樣品作為實際測試之前期試驗，實驗的參數包含載氣(N2、Ar)、功率(800W、1000W、1200W)以及土壤重量(1g、2g)。研究結果顯示，於1g土壤、載氣為N2、功率800W以及180秒的情況下，CH4總產氣量為254.2 ppm；2g土壤、載氣為N2、功率1200W以及420秒的情況下，CH4總產氣量為975.7 ppm；1g土壤、載氣為Ar、功率800W以及180秒的情況下，CH4總產氣量為5.42 ppm；於2g土壤、載氣為Ar 、功率1200W以及420秒的情況下，CH4總產氣量為39.8 ppm。另外也獲致以下結論：N2載氣比Ar載氣的產氣量高出許多；使用功率越高產氣量越多；隨著處理系統的反應時間越長，產氣量也隨著增加；增加土壤重量，產氣量也跟著變多。 本研究已成功藉由不同載氣以及反應功率取得各條件之土壤空白實驗數據，下期計畫可利用該等數據做為背景值，以降低系統誤差，提升微波電漿技術用於受有機物污染土壤整治之實驗可信度，提供土基會做為未來針對整治受有機物污染土壤之另一選擇。
計畫英文摘要	Soils contaminated by organic matter can be desorbed and decomposed by soil vapor extraction (SVE), Air Sparging (AS), Dual-phase Extraction (DPH), in-situ soil inversion and dilution, and heat treatment. However, the above treatment methods also have certain restrictions on removal conditions. And the microwave plasma proposed by this research produces microwave source through a magnetron, which generates high-energy electrons at room temperature. Compared with other plasma sources, the gas dissociation rate of microwave plasma is the advantages of plasma density, wide operating pressure range, rapid and uniform heating, and no need to use electrodes during operation. Compared with other technologies, the overall microwave plasma processing process does not produce secondary pollutants, and the processing cost is relatively low. It is lower than the heat treatment method. Therefore, this research built a set of microwave plasma system equipment to facilitate subsequent experiments on soil contaminated by organic matter. At present, the microwave plasma system has been used to complete the experiment. The outdoor soil is used as a sample, the parameters of this experiment including carrier gas (N2, Ar), power (800W, 1000W, 1200W) and soil weight (1g, 2g). The results of the study show that under the conditions of 1g soil, carrier gas of N2, power of 800W, and 180 seconds, the total CH4 gas production is 254.2 ppm; under the conditions of 2g soil, carrier gas of N2, power of 1200W, and 420 seconds, the total CH4 production volume is 975.7 ppm; when 1g soil, carrier gas is Ar, power of 800W, and 180 seconds, the total CH4 gas production is 5.42 ppm; when 2g soil, carrier gas is Ar, power is 1200W, and 420 seconds, the total CH4 gas production is 39.8 ppm. In addition, the following conclusions were obtained: N2 carrier gas has much higher gas production than Ar carrier gas; as the used power increases, the gas production increases; the longer the reaction time of the treatment system, the more gas is produced; the soil weight increases, and the gas production also increases. The experiment uses different gases and reaction powers to obtain experimental data under various conditions, and will be used in the future to reduce system errors, improve the experimental credibility of microwave plasma technology for soil remediation contaminated by organic matter, and provided “Soil and Groundwater Remediation Fund Management Board” as another option for remediation of soil contaminated by organic matter in the future.
