碩士 === 國立臺北科技大學 === 環境工程與管理研究所 === 100 === Due to the growing evidence of global warming and climate change affected by greenhouse gases, as well as the shortage of water supply in Taiwan and the international trend for low carbon emission society, to seek for the reduction in carbon emission and effect in recent years, at the moment calculation of emission is done through the Carbon Footprint. The main focus of promotion of the international society reduction in carbon emission initiative begins from large scale industries such as electricity, agriculture, production, transportation and so on, which expects to have the largest effect. As for the water purification plant of the water resources, due to less carbon emission, international investigation is mainly preliminary. Thus, the carbon emission on water purification is an important issue worth discussing. Due to the shortage in water resources in Taiwan, water recycling procedure seem more important. The procedure for the re-use of waste water of the Taiwan Water Corporation has been in operation for many years. This research focus on the procedure for the re-use of waste water of the Taiwan Water Corporation to conduct greenhouse gas interrogation and complete the calculation of carbon emission data. This data can be used as a reference for the promotion of lower emission and energy saving as well as the related improvement on energy policy in the future for domestic water purification plants. Such is also beneficial for the search for the space of lower carbon emission and effect. This study first review the literature with regards to the current processing situation of waste water and sludge procedure of domestic water purifying plants. The literature review also extends to the current international protocol for carbon footprint calculation and the use of carbon footprint calculation method to investigate and analyze the carbon emission of water purifying plants. Based on the literature, two representative water purifying plants were selected to study the reuse of waste water, the carbon footprint interrogation for sludge processing procedure and carbon emission reduction strategy. The data is based on the 2011 the actual interrogation statistic of the wet and dry season and the total carbon emission ratio. This study gathers various emission data on the reuse of waste water and sludge processing procedure for quantitative analysis. From the result, basic data on the carbon emission of such procedure is constructed as the basis of verification of the water purifying plant. Categorization of energy, supply materials, and infrastructure construction of the characteristics of various sources of carbon emission are discussed. Finally, amalgamating overseas and domestic related improvement strategies for the emission reduction initiative. Later, put forward the conclusion and recommendation on how can water purification plant improve waste water and mud processing procedure to reduce the energy wasted for the process.
