- Abstract:
- Boron?doped diamond (BDD) electrode electrochemical oxidation process with treatment scale of 12 m3/d was employed to treat the emulsion liquid and cutting fluid mixed wastewater from an auto parts factory. Except BDD electrode, other reaction conditions were as follows: adding sodium persulfate as electrolyte, current density of 50-80 mA/cm2 and electrolysis reaction time of approximately 3 h. The process was operated for a long time to investigate the electrochemical treatment performance. COD, ammonia nitrogen and petroleum in effluent were lower than 300 mg/L, 30 mg/L and 20 mg/L, respectively, and the removal efficiencies of COD and petroleum were higher than 99%. The effluent quality met the limits specified in Integrated Wastewater Discharge Standard (GB 8978-1996) and Liaoning Integrated Wastewater Discharge Standard (DB 21/1627-2008). The process has advantages such as simple equipment, small footprint area, easy operation and stability, which can provide reference for the treatment of similar wastewater．
