計畫中文摘要	本研究主題為開發智能化地下水污染整治系統，依序列式整治工法之施作順序，第1年研究聚焦於雙相抽除系統之節能控制，DPE系統優化調整最佳真空馬達運轉頻率為50 HZ，抽取地下水最佳的DPE運轉模式為「抽取5分鐘/停歇10分鐘」。第2年研究地下水氯苯濃度大於100 mg/L之6口DPE抽除井持續進行DPE系統抽除操作；並導入現地電解整治系統，於模場試驗高污染區外圍設置6口電解整治井，於電解整治井內直接氧化破壞溶解相污染物。比對模場試驗前DPE操作模式，優化DPE操作之污染移除率提升35%，節電量達55%。 啟動現地電解整治系統前，地下水氯苯初始濃度50.76~176.13 mg/L，經過30天電解過程地下水氯苯濃度大幅下降至25.47~76.97 mg/L，顯現明顯的污染整治效果。持續電解150天後模場試驗區地下水氯苯濃度大致呈現下降趨勢，氯苯污染濃度降幅皆大於50%，模場試驗區南側電解井地下水氯苯濃度可維持於20 mg/L以下。DPE抽除與現地電解統合式整治系統運轉約5個月，估算污染物總移除量約5.52 kg氯苯，其中DPE抽水移除氯苯約占總移除量70%，現地電解移除氯苯約占總移除量30%。 電解系統耗電量僅約DPE抽除系統的1%，導入電解整治系統可節省耗電量23.4%的操作成本。現地電解整治系統可藉由交替式逆向電解進行智能化控制，交替式逆向電解時間切換模式設定12~48 hr，可大幅降低井中電極表面披覆物重量，僅約3~12 g。
計畫英文摘要	The study objective is to develop an intelligent groundwater cleanup system. Following the groundwater cleanup procedures, the research is focused on the energy-saving control of the DPE system in the first year and the application of in-situ electrolysis apparatus in the second year. In the first year, the optimal vacuum pumping frequency is 50 HZ, and the optimal DPE operation mode is "5 minutes’ pumping/10 minutes’ standby" for DPE extraction. In the second year, 6 DPE extraction wells were continuously operating with groundwater chlorobenzene concentrations more than 100 mg/L. An in-situ electrolysis remediation system was installed with 6 electrolysis wells overlaid the highly contaminated area of the study site. Within the wells, dissolved contaminants were directly oxidized and destroyed by electrolysis. Compared to the previous DPE operation mode, the optimized DPE operation increased the contamination removal rate by 35% and saved 55% of electricity consumption. Before operating the in-situ electrolysis remediation system, the initial chlorobenzene concentration ranged from 50.76 to 176.13 mg/L in groundwater. After electrolyzing for 30 days, the chlorobenzene concentration significantly dropped to 25.47 to 76.97 mg/L. After continually electrolyzed for 150 days, the chlorobenzene concentration showed a declined trend in groundwater within the pilot test area, with reductions exceeding 50%. Chlorobenzene concentrations in the electrolysis wells were dropped to below 20 mg/L within the south region of the pilot test area. The integrated DPE extraction and in-situ electrolysis remediation system operated for about five months with an estimated removal of 5.52 kg chlorobenzene from the aquifer. DPE extraction accounted for approximately 70% of the total chlorobenzene removal, while in-situ electrolysis accounted for approximately 30%. The electrolysis system consumes only 1% electricity consumption of the DPE extraction system. Thus, the employment of the electrolysis remediation system reduced operating costs by 23.4%. The in-situ electrolysis remediation system can be intelligently controlled through alternating reverse electrolysis, with a timer setting of 12 to 48 hours. This significantly reduces the forming of the electrode coating within the well, and the electrode coating is about 3 to 12 grams of weight increase.
