計畫中文摘要	台灣之底泥污染情況相當普遍，不論是在河川中下游之底泥或是河口附近海水 底泥均已遭受污染，其中疏水性有機物及重金屬污染嚴重，污染物檢測濃度在全世界相關文獻報導中均名列前茅，如台南安順場址海水池底泥中戴奧辛與汞之污染，以及二仁溪底泥中之多氯聯苯、多溴聯苯醚、多環芳香烴類、聯苯二甲酸酯類塑化劑以及重金屬之污染，底泥污染也可藉由食物鏈破壞生態系及影響人體健康，急需經濟有效之整治技術。東南亞地區農地土壤也遭受相當高濃度之重金屬與有機物污染，農地污染直接衝擊食品安全及人體健康，而目前污染整治技術效果卻相對有限。由於本研究團隊於106 年度計畫結合現地相反轉及生物降解技術（ISPIE/BiRD）進行底泥污染整治之現地模場試驗，證實對於現地已經風化之多氯聯苯污染物Aroclor 1254 與六氯苯可在70 天內達到98%之去除率。本計畫之第1 年計畫也以實驗室批次降解實驗證實對於土壤中Lindane 及DDT 也相當有效；單次低溫ISPIE去除效率與多次相當，故於模場試驗將持續使用單次操作；快速玻璃化技術於實驗室批次實驗證實可應用土壤污染整治；相反轉去除研究已經證實可行，擴展技術應用廣度部分有兩面向，一面向為將此技術應用於戴奧辛污染底泥整治，另一面向為將此技術應用於遭受持久性有機污染物污染之土壤。ISPIE/BiRD 經證實可有效去除土壤中99.94%之DDT 及92.26%之Lindane。在優化原本技術部分，著重於改進乳化液配方以降低相反轉溫度，經測試結果可達到85.3±10.3%之去除率。本計畫也將底泥玻璃化技術成功應用於土壤重金屬污染土壤之玻璃化，並完成至少三種回收再利用技術研發，即現地再使用、瀝青玻璃原料與環保多孔材；戴奧辛之試行模場試驗結果顯示在35 天之內可將極低濃度之OCDD 與OCDF 降解去除82.8 %與93.6 %。本計畫為2 年期計畫之第2 年計畫，第1 年已完成實驗室批次實驗與管柱實驗，第2 年則為現地模場與砂箱試驗。目前已申請1 項專利、發表7 篇研討會論文及將完成1 篇SCI 期刊論文發表。
計畫英文摘要	Sediment contamination in Taiwan is a prevailing environmental problem no matter in freshwater and seawater. Concentration levels of some hydrophobic organic compounds (HOCs) and heavy metals are ranked at the front all over the world. For example, the sediments in a seawater lagoon at An-Sun site in Tainan is heavily contaminated by Dioxins and mercury while the sediment in Er-Ren River is highly contaminated by polychlorinated biphenyls, polybrominated diphenyl ethers, phthalate esters, polycyclic aromatic hydrocarbons, and heavy metals. Soils in the southeastern Asia are heavily contaminated by heavy metals and HOCs and very few cost-effective technologies are available. Our research team has successfully applied an integrated process by coupling in situ phase inversion emulsification and biological reductive dechlorination (ISPIE/BiRD) to achieve 98% removal of Aroclor 1254 and HCB within 70 days. The 1st year study on Lindane and DDT revealed that ISPIE/BiRD is effective on remediation of Lindane- and DDT-contaminated soils. In-situ vetrification is feasible for heavy-metal contaminated soils. The 2nd year study confirmed that ISPIE/BiRD can not only stabilize the heavy metals and the vitrified products can be recycled to make valuable porous materials. ISPIE/BiRD is definitely feasible in real soils by removing 99.94% of DDT and 92.26% of Lindane. In optimizing the ISPIE/BiRD on sediment remediation, a removal of 85.3±10.3% was achieved by a single operation of ISPIE. For dioxin remediation pilot study, 82.8 % and 93.6 % removals were achieved for OCDD and OCDF, respectively. The results highly support the vitrification of soils,ISPIE/BiRD on soil remediation, and ISPIE/BiRD on sediments contaminated by HCB,PCBs and dioxin-like compounds.
