摘要:
对汽车配件厂废乳化液、切削液的混合废水采用掺硼金刚石电极（BDD电极）电化学氧化工艺进行处理，处理规模为12 m3/d。采用BDD电极，加入过硫酸钠作为电解质，电流密度控制在50~80 mA/cm2，电解反应时间约3 h，对工艺进行长时间运行以考察电化学处理效果。结果表明：出水COD、氨氮、石油类浓度分别低于300、30、20 mg/L，COD、石油类的去除率均大于99%，出水水质满足《污水综合排放标准》（GB 8978—1996）及《辽宁省污水综合排放标准》（DB 21/1627—2008）。该工艺具有设备简单、占地面积小、操作方便、运行稳定等优点，可为同类废水的处理提供参考。
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．
