摘　　要：采用电化学氧化法去除养殖废水中的氨氮,以Ti/RuO_2-IrO_2为阳极,石墨板为阴极,考察电流密度、氯离子浓度、pH值对氨氮去除率的影响。结果表明:在电流密度为70 mA/cm^2,pH值为8～10,Cl^-浓度的质量浓度为5000 mg/L时,180 min内氨氮的去除率达到92.3%。Method of electrochemical oxidation was applied to remove ammonia nitrogen from aquaculture wastewater.The anode was Ti/RuO_2-IrO_2 expanded metal sheet electrode, the cathode was graphite plate electrode, the influences of different factors including current density, chloride ion concentration and initial pH on ammonia-nitrogen were studied. The results demonstrated that ammonia removal efficiency in electrochemical oxidation system could reach 92.3 % under the condition of 70 mA/cm^2 current density,with pH in the range of 8～10, and 5000 mg/L chloride concentration.
