Effects of Membrane Fouling in A²O-MBR System during Coking Wastewater Treatment

Abstract:

To treat coking wastewater with A²O-MBR hybrid process, membrane pollution control has become an important factor affecting the long-term stable operation of the system. The experiment reported in this paper focused on the membrane fouling of this hybrid system and try to evaluate the effects of aeration intensity and flux on the membrane fouling. The results show that the optimal parameters of membrane module operation are: aeration 0.2 m3/h, membrane flux 11.5 L/(m²·h), and with the maintenance of cleaning measures the membrane module can be kept under long-term stable operation.
