This paper discusses the concept of safety and reliability of wastewater reclamation systems, and proposes verification methods and evaluation systems to support the construction of safe, reliable, and economical wastewater recovery systems. The research aims to improve analysis models and evaluation index systems for further development in this field.
With the development of the world water resources situation, the reuse of wastewater will be one of the essential measures for solving water resources' problems and implementing practical and sustainable use of water resources. Wastewater reclamation risks have received considerable attention in all worlds, but research in this area is minimal, and a unified understanding and evaluation method has not yet been formed. Therefore, based on the system theory process analysis (STPA) method and hazard analysis and critical control point (HACCP) theory, this paper expounds on the concept of the safety and reliability of the wastewater reclamation system. Through the application of analysis methods, this paper proposes a verification method for the safety of the wastewater reclamation system and a reliability evaluation system for the wastewater reclamation system. Besides, the next research direction is further to improve the analysis model and evaluation index system to provide technical support for the construction of a safe, reliable, and economical wastewater recovery system.
