摘要
研究了一体式膜生物反应器(MBR)运行条件对反应器运行过程的影响。研究得出:在本试验条件下,中空纤维膜活性污泥反应器处理生活污水的最佳运行参数由大到小排列顺序为:水力停留时间(HRT)5h、抽吸时间12min,ρ(DO)3mg·L-1、停止时间6min;HRT对膜生物反应器的运行过程影响很大,主要反映了膜通量的大小。
This paper studied the effect of operational condition of submerged membrane bioreactor on operational process of the reactor. The results showed that: the sequence of process conditions was hydraulic retention time (HRT) 5 h, dissolved oxygen 3 mg·L^-1, suction time 12 rain and stopping suction time 6 min according to influencing size. HRT, mainly reflecting membrane flux, influenced the opration of MBR very greatly.
