A membrane bioreactor-reverse osmosis MBR-RO combined process was used for advanced treatment of coking wastewater from secondary biological treatment. MBR and RO units’ treatment efficiency for the pollution removal were conducted, and effects of raw water conductivity and trans-membrane pressure on water yield and desalination rate in RO unit were investigated in detail. The experimental results proved that MBR-RO combined process ran steadily with good treatment effect, which could obtain stable effluent water quality and met the requirement of “Design Criterion of the Industrial Circulating Cooling Water Treatment” (GB 50050-2007).
