The removals of sulfate and nitrogen from polyacrylonitrile fiber wastewater by coagulation anaerobic anoxic aerobic process were studied in laboratory scale. By this process, fair removals of 78%～82%, 95%～98%, 60%～65%, 75%～85% for COD, BOD, total nitrogen and EDTA respectively have been obtained. In the effluent the levels of COD, BOD and EDTA are in the sphere of 220～260 mg/L, less than 15mg/L and less than 25mg/L respectively and the NH 3—N and S 2- are not detectable.
