計畫中文摘要	近年來土壤污染場址整治多以現地處理為主，其耗時甚長，若以焚化處理則有二次污染之虞。本研究以磚窯實廠之高溫燒製程序，高溫分解油品污染土壤之有機物，不須添加額外能源。 本研究進行油品污染土壤與製磚原料(黏土)混拌，燒結成海洋復育環保磚，探討不同配比燒製出環保磚之強度及再利用性，並針對油品污染土壤及燒製產出之海洋復育環保磚進行金屬含量、毒性溶出測試及總碳氫化合物(TPH)分析，藉由分析可了解其藉由紅磚燒製技術可達到之處理效果。 經實驗結果顯示，以紅磚燒製技術處理油品污染土壤可大幅去除TPH，土壤TPH原污染濃度為3,068 mg/kg，經燒結紅磚之TPH含量均低於25 mg/kg，且其品質均可達到CNS 382之三種磚標準，以油品污染土壤添加15%其強度與吸水率表現最佳(抗壓強度495 kgf/cm2，吸水率2.81%)，抗壓強度為法規規範之3倍，吸水率標準為之1/5，透過28天之海水浸泡實驗後，抗壓強度並無顯著變化，顯示該磚體並未因海水浸泡導致磚體結構強度降解，而針對海水水質亦無明顯變化，顯示該海水環境並無受到污染之虞。 針對試驗磚、實廠磚及珊瑚復育盤對金屬含量分析後可以發現其重金屬含量皆為接近偵測極限，顯示其對海洋環境影響甚微，故可考慮進一步較大規模實驗，以推廣其進一步使用範疇。
計畫英文摘要	In Taiwan, the transportation vehicles are mainly fueled by gasoline. In 2020, there are 2,478 gas stations and most of them are old ones and have a high risk of oil leaching. Among them, 51 gas stations were declared as pollution remediation sites. Recently, the remediation technologies for the pollution sites are usually in-situ ones. These remediation processes consume much time and have limited effect. Incineration has high operation cost and high potential of secondary pollution. In this study, a sintering process in brick-kiln will be conducted to decompose pollutants in soil without adding extra energy. We mixed polluted oil, clay, and cullet with different ratios and sinter them into porous ecological-restoration bricks. The physical strength and TPH level of bricks were measured to evaluate the effect of sintering process. In addition, the feasibility of the sintering process to treat polluted soil will also be evaluated. In addition, sintered bricks will be immersed in seawater to evaluate their leaching behaviors and physical property in the ocean to ensure the safety of the ecological-restoration bricks. The results show that the sintering process greatly reduced the TPH levels from 3,068 mg/kg to 25 mg/kg. The quality of sintered product with a soil addition percentage between 5% to 20% met the criteria of CNS 382. Among them, the sintered brick with 15% of soil addition had the optimal physical property (compression strength = 495 kg/cm2, water absorption rate =2.81%) which were much better than the regulated standard. After immersing in seawater for 28-day, there was not any significant variation of compression strength and water quality. According to the analysis results of ecological-restoration bricks, the metal leaching concentrations were near the detection limits, indicating that the influence on the sea was slight. Therefore, the experiments for a large scale can be taken into consideration.
