摘　　要：在生物反应池中,通过改变曝气器的布置方式和水平流速,进行曝气充氧检测后得出结论:对于一定数量的曝气器,增加反应池的水平流速将会提高曝气器的充氧能力和氧利用率。同时,在供气量和其它条件不变的情况下,如果把曝气器相对集中布置,将会增加充氧能力,提高氧利用率。Aeration was carried out in a biological reactor tank through changing the layout of the aerators and the horizontal flow speed, with the following conclusions obtained after testing: with given number of aerators, the increase of the horizontal flow speed in the reactor tank improves the aerating capacity of the aerators and the oxygen utilization coefficient; meanwhile, with air supply and other conditions unchanged, a relatively centralized arrangement of the aerators increases the aerating capacity and improves the oxygen utilization coefficient.

关 键 词：污水处理 曝气器 充氧能力 氧利用率
