計畫中文摘要	本計畫擬整合循環式電動力CEEK技術及植生復育技術整治重金屬鉛污染土壤。依據過去的模場試驗成果顯示，CEEK能夠於短時間內快速去除土壤中的重金屬，殘留於土壤的重金屬可經由植生復育技術運用植物根系激素析出，再運用CEEK快速去除土壤中的重金屬，後續再利用植生復育技術析出殘留於土壤的重金屬，經兩技術交替運用使土壤重金屬濃度有效降低，並進一步探討相關處理效率、問題及成本，並評估本技術對於鉛污染土壤的處理效益。 本計畫實驗按照計畫書執行內容進行，目前已完成污染土壤的基本物化特性分析、模場試驗裝置、重金屬的移除效率及栽種玉米以進行後續植生復育試驗，試驗結果可以歸納如下：  本電動力系統CEEK經不斷改良下，系統具有簡便、組裝容易、運送輕便及可重複使用性，有利未來廣泛推展與實際進行。  本試驗經由不透水夾層的持續改善及測試，除了可大幅減少操作液的損失，也可降低污染物垂直移動所造成電鍍成效不彰的情況。  循環式電動力技術及植生復育整合下，其鉛污染土壤之最高濃度可從5,650 mg kg-1降至約2,083 mg kg-1，去除效率最高可約達到63%。  經電動力法整治後其土壤pH值及土壤有機質未有顯著改變，仍可栽種玉米作物，土壤並未產生毒化現象。  整合電動力法及植生復育之整治下，鉛金屬鍵結型態以鐵錳氧化態濃度最高，且鍵結型態顯著改變的現象並不明顯。
計畫英文摘要	In practice, for the contaminated sites to complete removal efficiency of heavy metals and maintain soil fertility, this study intends to using electrokinetics and phytoremediton to clean heavy-metal contaminated soils. Based CEEK mode test results show that CEEK could quickly remove heavy metals in soil for a short time in the past, and the residues heavy metal in soil could be precipitated via phytoremediation technique. At the same time, using the CEEK rapid remove the heavy metals in the soil, then the phytoremediation technique to precipitated the residues heavy metal in soil again. By using two techniques alternate until the concentrations of heavy metals in soil reaches the crops monitoring benchmark, and to further explore the treatment efficiency, problems and operation cost. The execution of experimental program according to the previous plans, the analysis of physical -chemical characterization of contaminated soil, mode experimental equipment, removal efficiency of heavy metal and planting corn for subsequent phytoremediation regulation have been obtained. Several conclusions and suggestions can be drawn:  After continuous improvement, the CEEK system possesses some features such as: more concise, easy construction, easy transport, and reusable. These features are beneficial to promote in the future.  The impermeable interlayer has been continuous improved and tested which can reduce the loss of operation solution and to enhance the effectiveness of cathode plating.  After the CEEK and phytoremediation treatment, the average Pb concentration in the contaminated soil could be decreased from 5,650 mg kg-1 to 2,083mg kg-1 and the removal efficiency could be achieved to 63%.  The pH value and organic matter in the soil change insignificantly after electrokinetics operation. The corn plant was still planted and poisoning phenomenon not occurred.  The Fe-Mn Oxides bound was highest concentration and the patterns distribution influence between electrokinetics and phytoremediton techniques insignificantly.
