Research progress of MBR technology and process in aquaculture tail water treatment

Membrane bioreactor technology（MBR） is considered as a potential technology for advanced water treatment in aquaculture, and there is still much room for improvement in the application of MBR in the field of aquaculture tail water treatment. Based on existing theoretical knowledge and combined with domestic and foreign literature, this article describes the current research status of efficient treatment technology, membrane pollution control technology, tail water recovery technology, and MBR technology improvement process for aquaculture tail water. Then the advantages and disadvantages of different MBR combined processes for nitrogen and phosphorus removal are compared. Finally, the problems of high treatment cost and poor integration of the treatment technology and aquaculture technology is pointed out in the research of aquaculture tail water treatment by the MBR technology and process. It is believed that this technology can be further studied in terms of integrated modularity, membrane materials and stabilization processes in the future. This article provides a reference and direction for the follow-up research on the efficient and economical application of MBR technology in aquaculture tail water treatment.
