碩士 === 中原大學 === 國際貿易研究所 === 96 === Abstract Technology plays important role to accelerate national development, economic effects and to improve the welfare of mankind. Recently, a lot manufactures have set their factories in Taoyuan County for expanding purposes. Traditional water sources are in shortage by abnormal weather changes in these years, therefore, some factors described as above, waste water recycling and water conservation concepts become important and may attract industry by gaining more benefits. The high technology of waste water treatment system is able to meet the criterion of Industrial Water Quality Standard and then contributes clean waste water pipeline network to each factory. Form this point of view, the treatment help investors cut-down cost on waste water issue also inspire more investment interest. At the same time, all of waste water resource conservation duty become more efficient to reach the goal of high recycling rate, and make advantages to environmental protection. This thesis is divided into two parts. The first one is questionnaire survey about water prosperities, intention of using waste water recycling system, processing water quality and aiming at system's upgrading plan. Another part is concerning with evaluation of benefits optimization of waste-water-recycling system in Jhongli Industrial Park. According to the survey ,we have found that more than 74% of factories under investigation agree on using waste water recycling system but 26% of it do not. Reasons of approvers are for water saving purpose and storage of water issues, while reasons of objectors have two concerns, one is worry about healthy issues, another is high cost associated with processing water quality. Both of approvers and objectors have a primary concern on cost issue. According to the result of benefit evaluation of wastewater treatment in this study, we have found that the unit cost of waste water treatment is around 11.58 NT dollars per cubic meter on 10,000 ton. With the production capacity of 20,000 ton per day, optimal benefits of 1,204,350,000 NT dollars can be obtained per year for the whole Jhongli Industrial Park. This benefit of applying waste water recycling system on cost efficiency may reach the goal that we expected.
