Membrane bioreactor(MBR) is an advanced wastewater treatment technology which has a vast development foreground. It is a combination of membrane separation with a biorea ctor. Coke-making wastewater is an industrial wastewater with high pollutant co ncentration and is difficult to be decomposed. The conventional treatment techn ology has many shortcomings, such as high expenses, low efficiency and so on. C oke-making wastewater is treated with MBR on laboratory scale. The MBR is regula tive. When the parameters of operation are regulated properly, the removal rates of COD and NH3<\sub> - N from wastewater can reach 80% and 98% respectively. The qua lity of water after treatment is steady and superior to the First Grade of Natio nal Discharge Standard. It is significant to spread MBR in engineering.
