The industrial wastewater from one bean products group is the research obj ect,the combined process(UASB-DAT-IAT)was designed to complete aerobic denitrification treatment,the obj ec-tive is to test the nitrogen removal effect in intermittent aeration operation mode and to study the influence of different dissolved oxygen concentration on the denitrification and the removal of or-ganic compounds.The results show that the average removal rate of total nitrogen is as high as 82% when using intermittent aeration operation mode and the dissolved oxygen concentration is 0.5 mg/L.
