計畫中文摘要	重金屬污染農地快速有效的整治方式具有極高研究及應用價值，特別是現地 污染整治的試驗更顯得重要。本研究以循環式之電動力法(Circulation-Enhanced Electrokinetics, CEEK)整治南投市某處鉛污染土壤，本計畫依據去年的成果進行 CEEK 系統改進，企盼藉由本計畫建構更具市場性的現地電動力法技術。 本試驗經過 100 天的鉛污染土壤整治，結果與計畫目標對應後可以歸納以下若 干結論： 1.本計畫確實建構一組 CEEK 專用的密閉式不透水渠道，克服操作液的循環量受天 候影響的問題，同時避免長久操作渠道變形問題。 2.本計畫確實建構 CEEK 可重複使用的密閉式不透水渠道。此渠道可於整治後重複 再使用，以利未來實際工程上節省初設成本 3.本電動力系統 CEEK 在近實場規模操作下，土壤的 pH 值及導電度維持在中性及 穩定的狀態，呈現本系統對土壤衝擊低。 4.本電動力系統 CEEK 在近實場規模操作下，系統電流及電壓維持在穩定的狀態。 同時，系統溫度接近大氣氣溫，呈現本系統的穩定性佳。 5.本電動力整治方法處理後的土壤肥力略降，需要添加適當肥料方能回復肥力。 6.本試驗經過 100 天污染土壤整治，土壤鉛的去除率僅約 2%，歸因其最可能的失 敗原因為離子交換樹脂的使用，經移除離子交換樹脂的使用整治 20 天後，鉛去 除效率約達 33%(土壤鉛濃度由 5,800mg/kg 降低至 3,800mg/kg)。
計畫英文摘要	The fast and effective remediation techniques for cleaning agricultural lands contaminated by heavy-metals are with high potential to be studied. The investigation of the in-situ remediation in pilot scale is especially important. This work applied the Circulation-Enhanced Electrokinetics (CEEK) to clean the lead contaminated soils in Nantou City. This project was proposed to improve the CEEK system based on the results from last year. We hope to establish the CEEK technique to meet the market requirements. After 100-day remediation for lead contaminated soils by the CEEK, several conclusions can be drawn: 1.A closing and uninfiltrated channel for the CEEK was constructed successfully, which avoids the weather effect and deformation problem during the long-term operation. 2. A reusable channel for the CEEK was constructed, which can be reused and save the initial cost. 3. The pH and electrical conductivity of soils could maintain neutral and stable situation, which indicated the little impact on soils under such CEEK process. 4. The electrical current and voltage could maintain stable situation, which presented the great stability of the CEEK process. In addition, the temperature of operational solution was close to atmospheric temperature. 5. The fertilizerbility of the treated soils was slightly less than that of the untreated soils. This means the addition of fertilizer is necessary 6.After 100-day remediation, the lead removal efficiency was around 2%. The most possible factor of the failure is the application of ion exchange resins. After removing the ion exchange resins and treating 20 days, the removal efficiency could reach 33%(from 5,800mg/kg to 3,800mg/kg)。
