Abstract：

 Submerged membrane bioreactor (MBR) was employed for petrochemical industry wastewater treatment. Transmerbrane pressure (TMP) and the TMP increasing rate (K) have been investigated under different aeration rates (300L/h, 150L/h and 75L/h). The result indicated that the evolution of TMP followed a simple exponential relationship with filtration time, i.e.  . K varied from 0 to 2.5 Pa/s under different aeration conditions. Change of aeration intensities presented insignificantly impact on the rising tendency of the K value. However, the aeration rates can change the characteristics of K increasing rate. The higher aeration rate can result in the slower increase of K. The result indicated that K could be potentially used to optimize the aeration in MBR and thus reducing the membrane fouling of MBR.
