摘　　要：采用SBM模型对2022年黄河流域上中游城市72座污水处理厂运行进行减污降碳协同增效综合绩效评估,减污降碳增效指标体系主要包括污染物去除类指标、经济投入指标和碳排放相关指标。采用Kruskal-Wallis方法对可能影响污水处理厂运行综合绩效的因素进行检验。结果表明:有18座污水处理厂运行综合绩效较好,其余54座污水处理厂运行综合绩效相对较低,其中纯技术效率值低是造成污水处理厂运行综合绩效值偏低的主要原因。综合绩效值为1的污水处理厂在降碳方面还有提升空间,综合绩效值<1的污水厂在投入产出指标中还存在不同程度的冗余;污染物运行负荷、排水标准、污水处理工艺、污泥处理处置方式是影响污水处理厂运行综合绩效的主要原因。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.
