- Abstract:
- Using analytic hierarchy process (AHP), a comprehensive evaluation system comprising four criteria and eleven indicators was established based on technical, economic, reliability, and environmental indicators, in conjunction with a reclaimed water plant’s actual operational data, enabling a systematic and quantitative assessment of the ozone system’s operational performance. The aim is to scientifically evaluate the operational efficiency of the ozone system in the reclaimed water plant, assist the plant in making data-driven adjustments to its operational strategies, and achieve the objectives of enhancing water quality while conserving energy and reducing resource consumption. This paper applied and evaluated the evaluation system through quantitative testing and analysis of two ozone treatment systems of a reclaimed water plant located in the central urban area of Beijing. The scoring of the M system’s water quality compliance rate and the instrument failure rate were 4.0 times and 7.7 times that of the G system, respectively. Additionally, the comprehensive score of the M system was 88.2% higher, indicating significantly better operational performance.
