計畫中文摘要	台灣土壤及地下水中之石油系有機化合物污染頻傳，每年僅環保署編列之整 治費用即可達2億元之額度，再加上台灣地區之土壤/地下水整治大多需分階段或合 併應用2-6種整治技術，故其設備之初設費與操作人員之訓練費用也相對的增高。 為此，本計畫擬整合雙相抽引法與高級氧化程序，開發出一套高效、可行、具有 市場競爭力之複合整治技術，以解決目前土壤及地下水油品污染之問題。 本研究選擇一污染場址，進行現地水文地質試驗及場址特性調查，並依其特 性建立一土壤層環境相同之實驗管柱進行實驗室中之污染物去除率試驗。本研究 針對污染場址在高濃度時，以雙相抽除法（Dual-phase Extraction）為污染物抽除 方法。抽出之液體經過簡易油水分離去除浮油後，以臭氧進階氧化技術處理水中 所含之可溶性有機污染物質，並將放流水接管至污染團地下水上游之接近地表之 土壤層中沖洗，以殘留有臭氧的將土壤孔隙中的有機污染物分解。在低濃度的環 境下，殘留臭氧的放流水在土壤層反應後會形成氧氣，提升土壤層中的含氧量，， 增進土壤中有機污染物好氧分解菌生長。 在目前實驗室研發階段中，已採集選擇污染場址中較高污染之土壤，並以實 驗室管柱模擬設備裝滿受污染土壤，將受污染之地下水經過高級氧化系統處理 後，再將含有高濃度之臭氧與氧氣之處理水補注回土壤層中，以模擬現地之污染 整治情況。目前之實驗已完成採集土壤之各項分析，其分析結果指出最主要之污 染物為土壤中總石油碳氫化物，此污染物同時也是臺灣地區加油站超過法規標準 最主要之污染物。研究結果指出，該複合方法能在34天內，分別去除土壤中與地 下水中93%與71.4%以上之柴油總石油碳氫化合物，且符合土壤1,000 mg/kg與地下 水10 mg/L之污染管制濃度。而有浮油存在之高濃度污染情形下，管柱實驗亦具有 相當不錯之處理效果。
計畫英文摘要	There are quite a few petroleum organic contaminated superfund sites in Taiwan, about two billion dollars expenditure on the remediation while only taking into account the expenditure from the Soil and Groundwater Pollution Remediation Fund annually. Moreover, the whole remediation process of contaminated sites usually needs 2-6 technologies in Taiwan. Thus, the construction costs of equipments and training costs of operators are high. A combined method of dual-phase extraction and advanced oxidation process (AOP) is employed in removing the petroleum organic compounds with the distinguishing features of rapid, effective, and economic. A contaminated site was selected as target to perform the hydrogeological survey. The laboratory scale experimental column was developed to test the removal efficiency based on the information of hydrogeological survey. In this investigation, the dual-phase extraction, AOP, and ozonic water flushing were performed in series to complete the experiment. Dual-phase extraction is the major method for pollutant extraction in the investigation. Separate the extraction liquid into oil and water layers, and recovery the oily organic pollutant. The extraction water was then treated with ozone and flushed through groundwater level to improve the pollutant solubility. The ozonic water was flushing through surface soil layer to remove the pollutant in the pore when the float oil layer inexistence. In addition, the ozonic water can release oxygen in the soil pore to prove a good environment for the aerobic microorganisms to decompose the pollutant. The petroleum-contaminated soil was sampled from a selected contaminated site, and stuff in a designed glass experimental column to simulate the pollutant behavior while pumped the AOP treated groundwater back into the contaminated soil. The total petroleum hydrocarbons (TPH) and benzene, toluene, ethylbenzene, and xylene (BTEX) of contaminated had been analyzed at the end of April 2011. The analyses data indicated that the TPH is the major pollutant in the selected contaminated site. The experimental data set indicated that TPHd concentrations of contaminated soil had been below the pollution control standards of soil (1,000 mg/kg) and groundwater (10 mg/L) in a 34-day treatment. The results of the floating oil column tests also show the combined method is an effective even at a very high pollutant contamination
