摘要：
Wastewater reclamation and reuse are an effective measure to alleviate water shortages. Water quality stability is the premise for safe utilization of reclaimed water and other water resources. Stable water quality can prevent the frequent occurrence of corrosion and scaling, which not only improves the sensory properties of water quality but also reduces secondary pollution and energy consumption. In order to promote the utilization of wastewater resources, it is important to evaluate and manage reclaimed water quality stability. Based on substantial literature and research, the characteristics and scopes of evaluation parameters for both chemical stability and biological stability were summarized, and a set of evaluation parameters and a system for reclaimed water quality stability were comprehensively established in this study. The evaluation procedure was mainly divided into four steps including: ① determine the influencing factors of reclaimed water quality stability; ② select corresponding evaluation parameters based on reclaimed water quality characteristics, the materials of pipelines, and equipment; ③ evaluate the reclaimed water quality stability; and ④ examine whether the evaluation results were appropriate. Finally, the potential challenges for the stability evaluation of water quality were analyzed. This study is expected to provide a theoretical foundation for the scientific evaluation of water quality stability and safe utilization of reclaimed water. © 2022, Science Press. All right reserved.
