摘　　要：随着城市污水生物处理技术的不断完善,污染物去除效率的不断提高,好氧生物处理技术逐渐成为城市污水处理的主导技术。好氧生物处理需要提供足够的氧气以满足微生物的正常生长,而维持供氧设备的正常运行需要消耗大量的电力,电量消耗已成为影响此类污水处理厂能耗的主要因素。在总结了现有的污水处理厂运行费用数学模型的基础,通过大量运行费用和处理效率数据,建立了以处理量Q、BOD5削减量,NH3-N削减量为变量的运行费用数学模型以分析影响污水处理厂能耗的因素,以实现城市污水处理节能减排的目标。With the continuous improvement of urban wastewater biological treatment technology and the higher efficiency demands of wastewater aerobic biological treatment, the aerobic biological treatment is taking up the dominant position o it is needed to provide enough oxygen to meet the normal growth of microbiology in aerobic biological treatment, so that a large amount of electricity is consumed to maintain the normal operation of air supply equipment, the electricity consumption is the major factor which affecting energy consumption of sewage treatment plant. To get the goal of energy saving and discharge decreasing, by quantity of operation data,we establish a mathematical model between running costs and pollutant treatment efficiency,flux, BOD5 cut,NH3 -N cut to analyze the factors affecting energy consumption most.
