摘　　要：农村生活污水处理设施示范推广中,对处理工艺进行定量优选评价有助于提高决策的科学性。为此,建立了一个考虑了经济性、有效性和适宜性的农村生活污水处理工艺评价指标体系,评价指标包括COD去除率、氨氮去除率、总磷去除率、基建成本、运行成本、占地面积、附加收益、技术稳定性、操作方便性和土地适宜性等。采用层次分析法对农村生活污水处理工艺备选方案进行优选评价,给出了评价标准和评价步骤,并进行了实例分析,评价结果符合当地的实际情况。该方法可为农村生活污水处理设施示范与推广中的工艺方案选择提供辅助决策分析工具。In demonstration and extension of rural sewage treatment processing facilities,quantified evaluation of the technology solutions can improve the scientific nature of decision-making.In this paper,a rural sewage treatment technology evaluation index system considering technology effectiveness,economy and efficiency was established,and the indicators included COD Removal Efficiency,NH+4-N Removal Efficiency,TP Removal Efficiency,Construction Cost,Operating Cost,Land Occupation Area,Additional Benefits,Technology Stability,Operating Convenience and Land Suitability.An assessment system for rural domestic sewage was established and the analytic hierarchy process was used as an assessment method to evaluate the alternative solutions and make decisions.The assessment standard and steps were also provided.Finally,a case study was conducted and achieved satisfactory results,and the evaluation results matched the local conditions.The method can be used as an auxiliary decision analysis tool for technology process solution assessment in demonstration and promotion of treatment works for rural domestic sewage works.
