Abstract

Abstract

The study applied the SBM model to conduct a comprehensive performance evaluation of the synergy between pollution reduction and carbon emission reduction for the operation of 72 wastewater treatment plants in the upper and middle reaches of the Yellow River Basin in 2022. The performance evaluation indicators include pollutant removal metrics, economic input metrics, and carbon emission-related metrics. The Kruskal-Wallis method was used to examine the factors that may affect the overall operational performance of the wastewater treatment plants. The results showed that 18 wastewater treatment plants performed well in terms of overall operational efficiency, while the remaining 54 plants exhibited relatively lower performance. Low values of pure technical efficiency were identified as the main cause of the insufficient performance in some plants. Plants with a comprehensive performance score equal to 1 still had room for improvement in carbon emission reduction, while those with a score below 1 displayed varying degrees of redundancy in input-output indicators. The key factors affecting overall operational performance include pollutant load, discharge standards, wastewater treatment processes, and sludge treatment and disposal methods.
