碩士 === 國立臺灣大學 === 環境工程學研究所 === 93 === Three compounds of environmental hormones, including Bisphenol A (BPA), Nonylphenol (NP) and Octylphenol Polyethoxylate (OPEO), have been widely detected in the rivers and effluent of the domestic wasterwater treatment plants. The objective of this study was to investigate the feasibility of several Advanced Oxidative Processes (AOPs) to degrade these three compounds. Based on the results, Granular Activated Carbon (GAC) enhanced the performance of ozonation for removing all selected pollutants. However, either combing with hydrogen dioxide (H2O2) or ultraviolet (UV), the removal efficiency of these compounds decreased during ozonation. During UV process, better removal efficiency for all three compounds happened under aeration. The results of BOD test imply the ozonation of NP and OPEO could promote the biodegradibilty . Overall, ozonation of all three compounds under acidic condition (pH=3) showed the better removal efficiency than under basic condition (pH=11).
