計畫中文摘要	本計畫(108)提出為期兩年之【建立三維多向性電動力模場優化系統之研究】，應用 Al 惰性電極及 Fe/Al 氧化電極進行電動力污染場址模場操作之研究，探討整治系統放大後對技術操作及試驗參數之影響，更針對電極井配置系統優化，進行研究以評估整治效能及成本效益，本計畫團隊已取得捷博公司合作意願，並請該公司協助模場系統設立、效能評估及技術推廣等事項，並未來將思考結合以電動力技術與該公司合作之可能性 。 電化學地質氧化技術具有優勢為：(1)使污染物移動具方向性、(2)能有效降解污染物、(3)污染場址處理多元化及 (4)易於結合其他技術提升整治成效；(5)可有效處理土相及液相之污染，藉由本計畫執行產出成果為(1)完成實場尺度 Fe/Al 氧化電極製備技術建立、(2)完成電動力模場配置系統規劃及建置、(3)完成電動力技術模場操作參數執行、(4)探討電極使用之經濟性、(5)完成電動力技術模場長期操作參數建立及(6)完成電動力模場處理效能及經濟效益分析。 本模場試驗之初進行土壤鑽探及設井工作時，發現現地具有許多垃圾回填物及重金屬顆粒，判斷其並非原生污染土壤，而於本場址先前相關報告書中並無提及此問題，於資訊不對等情況下易產生不利整治之情況產生。 本試驗比較電位坡降 0.6 及 1.0 V/cm、電極種類(惰性電極及氧化電極)及操作流質種類(地下水及乳酸)對現地土壤重金屬整治效果之影響，由實驗結果可看出添加 0.05 M 乳酸試驗組(T4)具有提升重金屬整治成效之效益 ，而比較經 Fe/Al 氧化電極整治後之重金屬相態變化結果顯示，(1)重金屬銅鐵錳氧化態比例減少、殘留態增加 ，顯示其去除以殘留態外其他相態為主；(2)重金屬鋅碳酸鹽結合態及鐵錳氧化態變化不明顯，而有機結合態比例減少導致殘留態比例增加；(3)重金屬鉻可交換態及碳酸 鹽結合態於整治後比例降低，殘留態比例則增加，顯示電 動力整治以較易移動相為主；(4)重金屬鎳整治後碳酸鹽 結合態及殘留態比例降低，鐵錳氧化態比例增加；而(5) 重金屬鉛整治後碳酸鹽結合態及殘留態比例微幅降低，鐵 錳氧化態及有機結合態比例則增加，顯示重金屬鉛不利於 土壤間移動；電動力整治 4 個月重金屬污染銅、鋅、鉻、鎳及鉛整治成效分別為 45.5%、-0.5%、28.6% 、25.7%及17.4%。 來年(109)計畫改善方向分別為(1)提升電位坡降：1.0 提高至 1.4 V/cm、(2)提高乳酸濃度：0 .05 提升至0.2 M 及(3)採樣點位置修正：進行電動力軸線採點以提 升後續整治成效。
計畫英文摘要	A two year project entitled "The study of establishment of the optimal three dimension multi-directional Electrokinetic prototype field system" was proposed. The Al electrode and Fe/Al oxidation electrode will applied in heavy metals pollutants contaminated site. The effect of scale-up on operation and experimental parameters will be investigated. The project is highly supported by JETPRO Technology CO., LTd. Intensive cooperation between JETPRO and NUK could be highly expected in the future. Electrochemical Geooxidation technology is valued on (1) controllable pollutant migration; (2) efficient degradation of organic pollutants; (3) site diversification; (4) good at combination with other technologies; (5) pollutant diversification. As a consequence, the expected results for this project are (1) preparation of Fe/Al oxidation electrodes with pilot plant scale; (2) planning and setup of electrode wells; (3) conducting pilot plant experiments; (4) recyclability analysis of electrodes; (5) establishment of long term operation parameters of Electrochemical Geooxidation technology; (6) performance and cost analysis for pilot plant system. When soil drilling and well setting were carried out at the beginning of this model field test, it was found that there are many garbage backfills and heavy metal particles on the site, and it is judged that it is not the original contaminated soil. This problem was not mentioned in the previous related reports at this site Unfair information is prone to adverse remediation. This experiments compare the effects of potential gradients ( 0.6 &1.0 V/cm ), electrode types ( inert electrodes and oxidation electrodes ), and types of operating fluids groundwater and lactic acid on the effect of remediation of heavy metals on the soil. From the experimental result, it can be seen that adding lactic acid of 0.05 M(T 4) has the benefit of improving the effectiveness of heavy metals treatment, and the comparison of the phase change of the heavy metals after use Fe/Al oxidation electrodes treatment shows that (1) Copper, Bound to Iron and Manganese Oxides is decreases , and Residual is increase , is shows that its removal by other phase than the Residual; (2) Zinc, Bound to Carbonates and Bound to Iron and Manganese Oxides do not change obviously, and Bound to Organic Matter is decrease ca use the ratio of Residual is increase ; (3) Chromium, Exchangeable and Bound to Carnonates is decrease after treatment , and let Residual has a big increase, it show that electrokinetic remediation was mainly based on the mobile phaes ; (4) Nickel, Bound to Carbonates and Residual and Residual is decrease, and Bound to Iron and Manganese Oxides is decrease, and Bound to Iron and Manganese Oxides has a big has a big increase; ; finally, (5)Lead, Bound to Carbonates and Residual were slightly decrease, and Bound to Organic Bound to Organic Matter has two times increase, it means lead was not moving well between soil. After 4 months of remediation for heavy metal pollutant treatment of Copper, Zinc, Chromium, Nickel and Lead is 45.5%、-0.5%、28.6%、25.7% and -17.4% respectively. The improvement of the 2nd year project (109) will be: (1) increasing potential gradient from 1.0 to 1.4 V/cm, (2) increasing lactic acid concentration from 0.05 to 0.2 M, and (3) shift sampling point to electric force axis to get the correct remediation efficiency.
