Abstract:
The process for wastewater treatment in submerged rotating membrane bioreactor (SRMBR) was studied. It was found that the effluent COD reduced to 20 mg/L after one day running when the influent COD varied from 160 mg/L to 368 mg/L. The equilibrium membrane flux increased rapidly with increasing rotation speed of membrane in the range of 0 to 25r/min. Within one minute, the increase of suspended suction time could alleviate the membrane fouling. Moreover, higher membrane flux could be reached even at lower aeration/water ratio (15:1) in SRMBR process. The optimum processing condition was suggested as follows: the rotation speed was 25r/min, suction time/suspended time was 9 min/1 min, aeration/water ratio was 15/1, and operation pressure was 25kPa. Under this condition, the equilibrium membrane flux could reach 53.75 L/(m2 x h).
