| 摘 要： | 以北京小红门污水处理厂的新、旧刚玉盘式微孔曝气器为例,进行曝气充氧性能的试验研究,并分析了更换曝气器对污水处理厂能耗的影响。结果表明:经过长期使用的曝气器充氧性能下降较大,氧总转移系数、氧的利用效率和动力效率分别下降了57%、58%和59%。旧微孔曝气器氧的利用效率为8.9%～14.1%,略高于中大气泡曝气器的性能参数,但由于微孔曝气器具有较大的阻力损失,使旧微孔曝气器的动力效率为1.5～2.1kgO2/(kW.h),低于中大气泡曝气器的性能参数。更换小红门全厂1/4的微孔曝气器后,鼓风机单耗降低21%,全厂能耗降低12%。因此,当微孔曝气器的充氧性能下降较大时,更换新的曝气器具有较高的节能和经济效益。
