計畫中文摘要	本計畫結合水蒸氣及電漿技術以整治有機污染場址，運用過熱水蒸氣強化熱脫附效果，並利用電漿重組有機污染土壤中之揮發性有機污染物，發展去污後維持土壤功能的永續循環程序。 本研究建置一套強化水蒸氣電漿處理有機污染土壤系統，設備包含蒸氣供給單元、電漿產生單元、反應單元以及尾氣處理單元，針對實驗室配置樣品以及實廠樣本進行試驗，修正選定實驗操作參數包含電漿處理時間、土壤含水率以及不同濃度負荷。實驗結果顯示，本研究系統均可達94%以上的去除率，且針對土壤肥力的檢測顯示能獲致土壤固氮的效果。能源效率則為1.46~1.49g Naphthalene /(kw·h)，整體系統處理污染土壤每公噸需40,000元。 系統藉由水蒸氣將微波輻射滲透到受污染土壤，迅速且高效能和無選擇性地破壞有機污染物，讓處理後的土壤達到污染物去除但保留其土壤肥力之功能，實現土壤非劣化循環使用，符合循環經濟及綠色協議之概念，也為永續韌性整治提供另一技術選擇。
計畫英文摘要	This project combines superheated steam and plasma technology to remediate organically polluted sites, uses water vapor steam to enhance thermal desorption effect, and uses plasma to recombine volatile organic pollutants in organically polluted soil, and maintain soil function after decontamination perpetual loop program. In this study, an enhanced water vapor plasma treatment system for organically polluted soil was built. The equipment includes a steam supply unit, a plasma generation unit, a reaction unit and an exhaust gas treatment unit. Experiments were performed on laboratory samples and samples from actual contaminated sites, with corrections for selected experiments. Operating parameters included plasma treatment time, soil moisture content, and different concentration loads. Experimental results show that this research system can achieve a removal rate of more than 94%, and soil fertility tests show that the effect of soil nitrogen fixation can be obtained. The energy efficiency is 1.46~1.49g Naphthalene /(kw·h), and the overall system needs NT40,000 per metric ton to treat polluted soil. The system uses water vapor steam to infiltrate microwave radiation into the contaminated soil, quickly, efficiently and non-selectively destroying organic pollutants, allowing the treated soil to achieve the function of removing pollutants but retaining its soil fertility, and realizing the soil non-degradation cycle The use is in line with the concept of circular economy and green agreement, and it also provides another technical choice for sustainable and resilient renovation.
