摘要

The Environmental Protection Administration (EPA) has been preventing water pollution, since 2016, the EPA has imposed cap-and-trade program on water pollutants. Additionally, in line with the National Water Environment Improvement Plan (2017 to 2021) of the Ministry of Economic Affairs (MOEA), the EPA has incorporated waterfront environments into its overall planning to improve the quality of water bodies. After few years, the average national river pollution index (RPI) dropped from 3.8 in 2002 to 2.5 in 2019, showing an improvement trend in the river water quality. For reservoir environmental management, the EPA has enhanced the application of Environmental Impact Assessment (EIA) by using water quality modeling since 2011 and adopt Forward-looking River Water Quality ＆ Environment Management Plan in 2020. In response to fish die-offs caused by hypoxia in river water bodies, this project analyzes relevant information such as the occurrence of fish mortality events in the past 5 years, climate conditions, etc., evaluates water oxygenation techniques and application methods, selects the Sanxia River in New Taipei City and the Yucheng Pumping Station outside waterway of the Keelung River in Taipei City for field testing, and through continuous aeration on-site testing and analysis to improve dissolved oxygen effectiveness, formulate suggestions for the installation location of subsequent oxygenation machines.
