碩士 === 中原大學 === 土木工程研究所 === 92 === Abstract In this research, the range of all river basin is consist of several mainstreams including Danshui River, Keelung River, Sindian River, Tahan River. Taipei City is used as a main area of population <a href="http://www.ntsearch.com/search.php?q=distribution&v=56">distribution</a> as well as the definition of boundary of building sewage sewer. In this investigation, the mode of QUAL2E is the simulator of <a href="http://www.ntsearch.com/search.php?q=water&v=56">water</a> quality of Danshui River. With this substantial data and completed examination, a set of complete scheme of Danshui River and the <a href="http://www.ntsearch.com/search.php?q=management&v=56">management</a> system of <a href="http://www.ntsearch.com/search.php?q=water&v=56">water</a> quality were established compared to ratios of prevalence of unitary and whole river basin of Danshu River. The outcome of this <a href="http://www.ntsearch.com/search.php?q=search&v=56">search</a> is concluded as follows: 1. The result of this mode can predict that the quality of sewage of Danshui would increase to 69.41%, follwed by the concentration of DO of Danshui River at 4.93 mg/L, and concentration of BOD decreased to 2.96 mg/L. 2. The result of this mode can predict that the quality of sewage of Danshui would climb to 69.41%, the concentration of DO of Danshui River would be 4.93 mg/L, and concentration of BOD decreased to 0.02 mg/L. The factor triggers the <a href="http://www.ntsearch.com/search.php?q=water&v=56">water</a> quality worse than expect is that Tahan River’s influx of a large amount of contaminants into DanShui River. This method is limited to a part of regions of Taipei County, thereby it is not better off than expect. 3. The outcome of this mode can predict the quality of sewage of Danshui River in Taipei City and Taipei County that will be rised steadily. The concerntration of DO would be 6.41 mg/L and the concentration of BOD would be declined to 0.02 mg/L. Therefore, in order to obtain more effective benefit, unitary areas have little singnificant effect on all Danshui River but whole areas do
