Experimental study on sequencing batch membrane bioreactor

Using sequencing batch membrane bioreactor (SBMBR) process, we had carried out an experimental study on municipal sewage treatment effect. Sequencing batch membrane bioreactor (SBMBR) was used as reclaimed water reuse system, we controlled membrane flux and dissolved oxygen within a reasonable range and researched sludge growth and the change of water quality in the SBR and MBR reactors at all stages, the average removal efficiency of COD, NH3-N, total nitrogen(TN) and total phosphorus(TP) reached 90.64%, 92.81%, 67.38% and 74.33% when the effluent quality was stable. The results show that SBMBR for sewage treatment worked well, effluent quality of system reached at or better than ≪The reuse of urban recycling water—Water quality standard for urban miscellaneous water consumption≫ when the effluent quality was stable, the SBMBR process that was used as reclaimed water reuse system can be applied in reclaimed water reuse engineering.
