主 题：forward osmosis membrane bioreactor,bisphenol A microfiltration
摘 要：Forward osmotic membrane bioreactor is an emerging technology that combines the advantages of forward osmosis and conventional membrane bioreactor. In this paper, bisphenol A removal by using a forward osmotic membrane bioreactor and a conventional mem- brane bioreactor that shared one biologic reactor was studied. The total removal rate of bisphenol A by the conventional membrane bioreactor and forward osmotic membrane bioreactor was as high as 93.9% and 98%, respectively. Biodegradation plays a dominant role in the total removal of bisphenol A in both processes. In comparison of membrane rejection, the forward osmosis membrane can remove approximately 70% bisphenol A from the feed, much higher than that of the microfiltration membrane （below 10%）. Forward osmosis membrane bioreactor should be operated with its BPA loading rate under 0.08 mg. g-1. d-1 to guarantee the effluent bisphenol A concentration less thanlO μg·L-1.
