Abstract:	近年來新興污染物(Emerging Contaminants,EC) 的污染問題備受矚目，烷基苯酚 (Alkylphenol,AP)，於環境中不易分解，而有關烷基苯酚對生態的危害已經由廣泛的研究證實，包括對水中生物毒性、有限的生物分解性、環境的持久性，以及環境荷爾蒙效應，其對人體的內分泌系統與健康造成潛在的威脅。 O3 結合UV/H2O2 程序可透過連串化學反應，產生氧化力極高的氫氧自由基，相較於其他種類的氧化系統組合，效果更佳。本研究期望藉由UV、O3、H2O2 三者共氧化劑形式達到加成的作用。藉由改變O3/UV/H2O2 之操作條件，進一步探討O3/UV/H2O2 程序降解烷基苯酚(NP 及OP)的處理能力、最適操作條件、和降解機制。並且評估O3/UV/H2O2 程序對環境荷爾蒙物質處理之可行性，以提升此技術的應用層面。The pollution problem of emerging contaminants is concerned in recent years. Among emerging contaminants, alkylphenol (NP and OP) is one of chemicals that are not easy decomposition in the environment. Also, the hazard of alkylphenol to ecological effects, including aquatic toxicity, limited biodegradation, environmental persistence and harmonic interruption, has been wildly investigated. It was verified that alkylphnol could cause the potential threat to human health and endocrine disruption. O3 combined with UV/H2O2 process could make serial chemical reactions and produce more active hydroxyl radicals which have stronger oxidation capacity than conventional oxidants. Consequently, O3/UV/H2O2 process would be more effectiveness as compared to other types of oxidation combination system. This study is expected to combine the three oxidants, UV, O3, and H2O2, in order to enhance the synergistic effect on increasing the oxidative efficiency for alkylphenol degradation. The experiments would be carried out at different operating conditions of O3/UV/H2O2 process. In addition, the degradation efficiency, the optimal operating conditions, and the degradation mechanisms of alkylphenol (NP and OP) by O3/UV/H2O2 process would be further investigated. The feasibility of O3/UV/H2O2 process to deal with the environmental hormone would also be evaluated for promoting the application aspects of this technology. 研究期間：10008 ~ 10107
