計畫中文摘要	應用生物整治技術復育氯烯類污染地下水經常面臨代謝副產物累積、生物遲滯或污染濃度回升等問題，主因為現地環境難以即時掌握水質變化趨勢，以調整藥劑添加比例與時機，導致無法維持微生物的最適降解環境。因此本計畫在進行中的地下水污染場址，透過自動水質連續監測設備結合物聯網(IoT)技術，監測生物整治工法過程的水質變化以評估厭氧環境的營造與藥劑補注之時機，創造精準加藥的最適當參數，穩定生物厭氧脫氯作用環境，作為生物整治策略制定及整治效能評估的依據。 本計畫共選定四項水質參數(pH、EC、ORP與TOC)，於試驗場址執行連續監測作業，收集連續監測與標準採樣分析方法所取得之數值並迴歸期間之相關性，相關係數(R)均達0.8以上，現地即時監測與標準分析方法間具有良好的相關性，可有效反映真實地下水質變化。觀察連續監測結果發現，監測區域於灌注乳化基質後，地下水pH及EC皆符合灌注初期至穩定期之趨勢，TOC則持續呈現下降的趨勢，顯示碳源被微生物逐步消耗，而ORP數值維持於-100 mV以下，顯示地下已建立利於微生物厭氧脫氯作用之還原環境。 此外，連續監測之溫室氣體排放量較傳統採樣、檢測分析作業減少約500 kgCO2e，證實達到減碳效益及綠色整治目標，且顯著降低人力與檢測成本，具備高時效性、可靠性與永續價值，未來可作為氯烯類污染場址精準整治的核心監測技術之一。
計畫英文摘要	Bioremediation of chlorinated hydrocarbons-contaminated groundwater often faces problems such as metabolic byproduct accumulation, biohysteresis, or rebound in contamination concentrations. This is primarily due to the difficulty in monitoring groundwater quality trends in the field accurately to adjust the proportion and timing of remediation agents addition, resulting in an inability to maintain an optimal degradation environment for microorganisms. This study applied automated continuous monitoring equipments combined with Internet of Things (IoT) technologies at ongoing groundwater contamination sites to monitor water quality changes during remediation processes. This allows for assessment of anaerobic environment creation and agents injection timing, estimating optimal parameters for precise dosing and stabilizing the biological anaerobic dechlorination environment. This serves as a basis for bioremediation strategy development and remediation effectiveness evaluation. This project selected four water quality parameters (pH, EC, ORP, and TOC) for continuous monitoring at this site. The values obtained from continuous monitoring sensors and standard sampling and analysis protocols were collected and regressed. The correlation coefficients (R) were all above 0.8, indicating a good correlation between semsors and standard methods, effectively reflecting actual groundwater quality changes. Observation of the continuous monitoring results revealed that after the injection of the emulsified oils, the groundwater pH and EC followed the trend from the initial injection stage to the stable stage. TOC showed a downward trend, indicating that the carbon source was gradually consumed by microorganisms. The ORP value remained below -100 mV, indicating that a reducing environment conducive to anaerobic dechlorination by microorganisms had been established underground. Furthermore, continuous monitoring reduces GHG emission by approximately 500 kgCO2e compared to traditional sampling, testing, and analysis operations during four months, demonstrating the achievement of carbon reduction benefits and green remediation goals. This significantly reduces labor and testing costs, and demonstrates high timeliness, reliability, and sustainable value. In the future, this technology could serve as one of the core monitoring technologies for the precise remediation of chlorinated hydrocarbons-contaminated sites.
