In order to increase removal efficiency in pharmaceutical wastewator,including internal circulation anaerobic reactor on the existing treatment process,and far deeper research of IC reactor's start-up condition. The practical application of internal circulation anaerobic reactor in treatment engineering of vitamins production waste-water was studied,and the operation efficiency of reactor is analyzed,The start-up testing lasted 127 days,The operation results show that the VFA (acetic acid) density of effluent water was lower than 200 mg·L~(-1)、COD removal rate was higher than 90%、pH kept at 6.7～7.7.The system operates stably and has high pollutant removal efficiency.
