摘　　要：针对化肥厂废水氨氮和硝酸盐氮浓度高、BOD_5/COD值低的特点,采用电化学氧化法去除化肥废水中的高浓度氨氮。分别考察了电流密度、氯离子浓度、溶液pH值对氨氮去除率的影响。结果表明:在采用Ti/RuO_2-IrO_2做阳极,电流密度60 mA/cm^2,氯离子浓度4000 mg/L的条件下,氨氮的去除率可达到86.7%。The treatment of electrochemical oxidation for fertilizer plant wastewater with high ammonia concentration was investigated,as the characteristics of high concentration of ammonia nitrogen and nitrate nitrogen and low value of BODs/COD in wastewater of chemical fertilizer plant. The influences of different factors including current density, plate distance, chloride ion concentration and initial pH on ammonia - nitrogen and total nitrogen removal were studied. The results demonstrated that ammonia removal efficiency in electrochemical oxidation system could reach 86.7% under the condition of 60 mA/cm2 current density,4000mg/L chloride concentration and Ti/RuO2 -IrO2 as anode.
