摘　　要：为科学评价水处理设施运行效果,从经济、技术、管理、环境4个角度建立了包含12个指标的一体化水处理设施运行效果评价指标体系,结合熵权法和层次分析法,确定指标的权重,并利用模糊综合评价模型对三峡库区农村移民安置区一体化污水处理设施运行效果开展综合评价。结果表明:从设施工艺角度评价,活性污泥法在经济方面优势明显,生物膜法在管理方面优势较大;从运维管理方角度评价,第三方运维单位在经济、技术、管理方面优势显著。运行成本、水质达标稳定性、单位投资这几个二级指标对运行效果评价的影响较大,建议一体化污水处理设施在设计和管理中对这些方面做出积极响应。研究成果可为三峡库区水污染治理和农村人居环境提升提供重要支撑。To scientifically evaluate the operation effect of sewage treatment facilities,an evaluation index system for the operation effect of integrated sewage treatment facilities containing 12 indicators was established from four perspectives,such as economy,technology,management and environment.Combined with the entropy weighting method and hierarchical analysis method to determine the weights,we utilized the fuzzy comprehensive evaluation model to evaluate the operation effect of sewage treatment facilities in rural migrant resettlement areas in the Three Gorges Reservoir area.The results showed that from the perspective of the facility technique,the activated sludge method had obvious economic advantages,and the biofilm method had greater maintenance advantages,and the third-party operation and maintenance unit had significant advantages in terms of economy,technology and management.Among them,the secondary indicators of operation cost,stability of water quality and per investment had a greater impact on the evaluation,and it was recommended to consider these factors in the design and management of the treatment facility.The research results can provide important support for the Three Gorges Reservoir area water pollution management and rural habitat improvement work.
