Membrane bioreactor (MBR) technology has previously been used by water industry to treat high salinity wastewater. In this study, an anoxic-oxic biofilm-membrane bioreactor (AOB-MBR) system has been developed to treat mustard tuber wastewater of 10% salinity (calculated as NaCl). To figure out the effects of operating conditions of the AOB-MBR on membrane fouling rate (KV), response surface methodology was used to evaluate the interaction effect of the three key operational parameters, namely time interval for pump (t), aeration intensity (UGr) and transmembrane pressure (TMP). The optimal condition for lowest membrane fouling rate (KV) was obtained: time interval was 4.0 min, aeration intensity was 14.6 m3/(m2￥h) and transmembrane pressure was 19.0 kPa. And under this condition, the treatment efficiency with different influent loads, i.e. 1.0, 1.9 and 3.3 kg COD m-3d-1 was researched. When the reactor influent load was less than 1.9 kg COD m-3d-1, the effluent could meet the third discharge standard of “Integrated Wastewater Discharge Standard”. This study suggests that the model fitted by response surface methodology can predict accurately membrane fouling rate within the specified design space. And it is feasible to apply the AOB-MBR in the pickled mustard tuber factory, achieving satisfying effluent quality.
