摘　　要：采用数学分析法解析了太湖流域某污水处理厂近十年的能耗数据,分别研究了水量、污染物、水温对能耗波动的影响规律及影响程度。研究发现,该厂近十年吨水能耗的变化范围为0.15~0.45 kW·h/m^(3),波动幅度大;影响因素分析发现,吨水能耗与水量呈幂函数负相关,水量每增加10%,吨水能耗减少约12%,呈现规模效应;各类污染物中,含氮污染物对能耗波动影响最显著;在温度变化幅度较大的时段,吨水能耗与水温基本呈负相关。综合比较发现,水量对能耗波动的影响程度最大,可为污水处理厂稳定运行的评估提供借鉴。This paper analyzed the energy consumption data of a wastewater treatment plant in Taihu Lake basin in recent ten years by mathematical analysis method,and investigated the effects and influence degree of water quantity,pollutants and water temperature on energy consumption fluctuation,respectively.In the past ten years,the energy consumption per volume of wastewater in the plant fluctuated significantly in the range of 0.15-0.45 kW·h/m^(3).The analysis of influencing factors indicated that the energy consumption per volume of wastewater was negatively correlated with the water quantity as a power function.For every 10%increase in water quantity,the energy consumption per volume of wastewater was reduced by approximately 12%,showing that there was a scale effect.Among various pollutants,nitrogen-containing pollutants had the most significant influence on energy consumption fluctuation.The energy consumption per volume of wastewater was negatively correlated with water temperature in the period of large temperature variation.A comprehensive comparison showed that water quantity had the greatest influence on fluctuation of energy consumption,which could provide a reference for evaluating the stable operation of wastewater treatment plants.
