| Summary: | 碩士 === 國立高雄第一科技大學 === 環境與安全衛生工程研究所 === 102 === To relieve the signs of drought that have become increasingly common in recent years the Construction and Planning Agency of the Ministry of the Interior and the Water Resources Agency of the Ministry of Economic Affairs plan to jointly promote the recycling and reuse of effluent at public sewage disposal works in Taichung, Tainan, Kaohsiung and other areas were water resources are in increasingly short supply. If we take the Fengshan River sewage disposal works in Kaohsiung City as an example, the plan is to first subject effluent to treatment with thin film advanced waste treatment before supplying it to coastal industrial zones for industrial uses. This will increase the efficiency of water resource usage and stabilize local water supplies. There are already many documents discussing the possibility of using thin film technology to recycle and reuse effluent. However, most research in the field uses simulated sewage as the water to be treated, and a majority of experimental pilot plants are less than 1CMD in operational scale. Although this approach makes it possible to minimize the impact of fluctuations in water quality and the research process easier to control, if we apply the conclusions of this research to the planning of real world plants there would be major differences. As such, this research will involve the installation of a 50 CMD UF+RO thin film recycling system at the Fengshan River sewage disposal works to discuss the impact of water production rate, backwash frequency, backwash tablets, operational pressure, and other operational conditions on operational costs, the amount of tablets used, water volume produced, and the operational life of the thin films. The ultimate objective is to determine the design parameters and optimal operational conditions needed to construct a thin film sewage recycling plant.
