碩士 / 國立臺北科技大學 / 環境工程與管理研究所 / 107 / In Taiwan, due to extreme climate, uneven rainfall distribution and decline of reservoir storage capacity, the desalination plant was built to make up for the shortage of fresh water supply. Seawater plant extract seawater from the ocean, after physical or chemical pretreatment, and then use water treatment technology to obtain freshwater products. However, the process of water purification will produce high concentration brine and biological deposits of sea sand by-products. In Taiwan, by-products are mainly disposed of according to the " Waste Disposal Act " and " Marine Discharge Pipe Effluent Standards ".
In recent years, seawater desalination plant has begun to research how to use it as a reusable resource in order to solve the problem of waste produced in the process, and to explore the feasibility of its development channels and benefits in combination with academia. It can be seen that the issues related to by-products of seawater desalination plant have attracted much attention. Moreover, the by-products produced from seawater desalination plant belong to natural resources. If they are released or discarded by Taiwanese laws and regulations, they will cause waste of resources and environmental impact.
Based on the literature and comparative analysis, this study aims to understand the connotation of circular economy development, the development of seawater desalination and the general situation of environmental impact and reuse of by-products, and put forward the thinking of circular economy of seawater desalination and the strategies of reuse and resource utilization of by-products.Circular economy is to extract the use value of waste resources into reusable materials, reduce waste and environmental impact, so that material resources can be recycled continuously. If the waste by-product resources of the process can be properly disposed of, recycled and reused, and its resource-based technology and high efficiency can be improved, the generation of waste can be reduced and prevented. This study hopes to put forward a systematic and sustainable management plan for seawater desalination plant based on the idea of circular economy, so as to benefit all units for reference.
