摘要
在对环太湖流域4座采用氧化沟工艺的城市污水处理厂进行能耗调研的基础上,以吨水位能耗(E)、生化段装机容量(η)、有机物去除量(ΔCOD)、氨氮去除量(ΔNH3-N)、总磷去除量(ΔTP)作为评价氧化沟法城市污水厂能耗的指标,结合隶属度函数,应用单因素模糊综合评价法对所调研的污水处理厂进行能耗水平定量评价。得出A污水处理厂的能耗级别为二级,B和C污水处理厂的能耗级别为三级,D污水处理厂能耗级别为五级。级别越高能耗越大。
Based on the data of four wastewater treatment plants（WWTPs） in Tai Hu watershed,the energy consumption per ton of wastewater（E）,the installed capacity of biochemical treatment process（η）,the removal volume of COD（ΔCOD）,the removal volume of NH3-N（ΔNH3-N） and the removal volume of TP（ΔTP） were chosen as indices for evaluating the energy consumption of the WWTP.Fuzzy synthesized assessment was adopted to quantitatively evaluate the energy consumption level.The energy consumption levels of A,B,C and D WWTP were level 2,level 3,level 3,and level 5,respectively.The energy consumption level of WWTP varied directly with the grade.
