摘要：
A sequencing batch MBR-RO system has been developed to treat coking wastewater, focusing attention on the COD and TN removal efficiencies. Operational results over 60 days showed that the sequencing batch MBR-RO system had a great impact on removals of COD and TN. the removal efficiencies of COD and TN were 93% and 96% respectively. Final concentrations in the effluent of 0.24 mg phenols/L, 0.02 mg cyanides /L, 28.7 mg COD/L and 4.53 mg TN/L were obtained. In addition, the flux of MBR and RO lost 65.3% and 73.2% respectively.
