Abstract

To promote the sustainable development of reclaimed water utilization, this study focuses on reclaimed water use in Changxing County, Zhejiang Province, China. Based on the United Nations Sustainable Development Goals (SDGs) framework, an evaluation index system for reclaimed water utilization benefits was developed. The Analytic Hierarchy Process (AHP) and Entropy Weight Method (EWM) were used to determine weights, and the Grey Relational Analysis Model was employed to assess the benefits. The results indicate that reclaimed water utilization is closely related to four SDGs (SDG 6, SDG 8, SDG 9, SDG 12) and their eleven specific targets (e.g., SDG 6.3, SDG 6.4, SDG 6.5). The index system includes five criteria and 25 indicators. Between 2015 and 2022, the benefits of reclaimed water utilization in Changxing County have steadily increased, divided into three periods: Initiation Exploration (2015–2016), Steady Improvement (2017–2019), and Good Performance (2020–2022). Indicators requiring the most improvement include Water stress level, Unconventional water use rate in industrial production, and Fiscal input ratio. Improvement suggestions include implementing diversified measures to alleviate water stress, increasing industrial water use rates, and enhancing policy mechanisms to support sustainable water resource management.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
