利用自然技術削減地下水有機氯化物污染之節能整治技術研究近年來因全球氣候異常導致台灣產生非澇既旱之極端氣候現象頻率增加，這也導致台灣水資源的保育管理成為水資源永續發展中不可或缺的一環。地下水為人類主要地淡水來源，但工業及農業廢水、工業生產、運送或儲存造成化學物質滲漏至地下，都可能會造成地下水污染，其中又以含氯有機物為最為常見的污染物，目前傳統的處理技術相當耗費能源且技術需求層次高，因此在這水資源匱乏且飽受污染的當下，利用低成本、低耗能且無二次污染的人工濕地處理含有機氯化物之地下水，不但能美化環境還能達到節能減碳的目標。本產學合作計畫與具備監測、處理污染地下水技術之廠商合作，透過設立小型的人工濕地模場，分析人工濕地系統應用於處理受有機氯化物污染之地下水之可能性，並探討以下課題：(1)含氯有機物污染水質特性探討；(2)比較不同類型人工濕地系統處理含氯有機物地下水的能力；(3)比較不同植栽人工濕地處理含氯有機物地下水的能力；(4)比較傳統技術與自然淨化技術能源耗費成本；(5)綜合以上結果所獲得之參數，評估以人工濕地處理含氯有機物地下水所需的成本。本研究成果將可立即提供合作產商評估以實場規模人工濕地系統進行受污染地下水整治所需的設計參數與設置管理成本，並立即應用於實場之整治。 Research of Energy-Saving Natural Treatment Technologies for Chloro-organics in Polluted Groundwater Reduction Reservation and management of water resources become significant issue due to drought and flooding problems caused by extreme climate recently. Groundwater is one of important freshwater resource for human life, but the industry and agriculture waste water and the chemical from the results of the industry production, transportation and storage percolate into the ground, and all these would cause pollution of groundwater. Chloro-organics is the most common pollution of the groundwater. At present, the techniques applied for groundwater decontamination require lots of money for energy and man-power. This collaboration project is trying to seek out feasible techniques for groundwater restoration and also with low cost or management requirement. constructed wetlands (CW) have been proved to be low-cost and low-labor technique for polluted water treatment by several practical cases within the country. And CW can not only beautiful our environment but also save energy and reduce CO2 emission. The industry collaborated in this project has mature techniques for monitoring and decontamination of groundwater. The goals of this collaboration projects are to use pilot-scale CW system to study the feasibility of treating chloro-organics polluted groundwater. The research topics include: 1. the characteristics of chloro-organics polluted groundwater for CW inflow and outflow; 2. comparisons of the treatability on various types of CW on gasoline polluted groundwater; 3. comparisons of the treatability of various macrophytes on chloro-organics polluted groundwater; 4. summarization of the research data and parameters to evaluation the costs of using CW for chloro-organics polluted groundwater. The research results expected be used immediately for the collaborated industries to design full-scale CW system to evaluate the requirements of design parameters and installation costs for treating gasoline polluted groundwater and apply on-site to restore polluted groundwater.
