摘　　要：利用昆明市17座污水处理厂数据构建适用于昆明市的污染物处理费用函数,并依据昆明市"十三五"规划目标,以2015年为基准年,设计4种减排情景,对2025年不同情景下昆明市污水处理厂的费用效益进行分析。结果表明:城市排水管网改造与强化管理对提高污水处理厂效率,充分挖掘其污水处理潜力至关重要,该情景目标年费效比较基准情景降低了0.22,削减单位COD、NH_(3)-N、TN和TP可分别节省0.093元/m^(3)、0.251元/m^(3)、0.137元/m^(3)和0.280元/m^(3),污水处理厂效益明显改善。Taking Kunming as an example,the cost function of pollutant treatment suitable for Kunming is constructed by using the data of seventeen wastewater treatment plants in Kunming.According to the targets of the 13 th Five-Year Plan of Kunming,four emission reduction scenarios are designed based on 2015 as the base year,and the cost and benefit of Kunming wastewater treatment Plant under different scenarios in 2025 is analyzed.The results show that the urban drainage network reconstruction and strengthening management is very important to improve the efficiency of wastewater treatment plant and fully tap the pollutant treatment potential.The cost-benefit ratio of the target year for this scenario is 0.22 lower than the baseline scenario.The unit treatment cost of COD,NH_(3)-N,TN and TP can be saved by 0.093 yuan/m^(3),0.251 yuan/m^(3),0.137 yuan/m^(3)and 0.280 yuan/m^(3),respectively.The benefit of wastewater treatment plant is obviously improved.
