摘　　要：对废水处理技术性能的综合评估是提高废水处理效率的主要途径,同时也能提高处理技术的经济性。采用层次分析法(AHP)对屠宰废水的处理技术进行优选。利用实验室中试实测COD、TN和TP的去除率,并结合专家咨询法对判断矩阵进行赋值。以3套组合工艺作为方案层,综合效益作为目标层,经济效益、技术性能、管理效益作为准则层建立层次模型和判断矩阵。通过判断矩阵中各因素标度与权重,优选了屠宰废水最佳处理方案为上流式厌氧污泥床(UASB)/序批式活性污泥法(SBR)组合工艺。AHP为屠宰废水处理技术产业化过程中的性能评估提供了科学依据。Evaluating wastewater treatment performance is a main approach to improve treatment efficiency and can play an important role in strengthening the economic benefits. AHP was used to optimize slaughter wastewater treatment technology. The removal efficiencies of COD,TN and TP obtained from pilot test were combined with expert judgments to assign the judgement matrix. Three slaughter wastewater treatment combined processes were taken as the project layer,comprehensive benefit as the target layer,the feasibility of three combined processes in economy, technology and management benefit as the objective evaluation layer, then hierarchical model and judgement matrix were established. The optimum slaughter wastewater treatment process was UASB/SBR through calculating the scale and priority of factors in judgement matrix. AHP provided scientific evaluation basis for industrialization of slaughter wastewater treatment.
