摘要
研究利用电化学催化氧化法深度处理经生物处理后的垃圾渗滤液时,电压、氧化时间、氯离子浓度及温度对有机物降解的影响。试验结果表明:在电压3.5V,电流密度为7.0mA/cm2,氧化时间2.5h,氯离子的浓度2000mg/L的条件下,垃圾渗滤液的CODCr由464.0mg/L降低到200.0mg/L.NH3-N的去除率大于95％。
Advanced treatment of landfill leachate by electrochemical catalytic oxidation has been expounded, and the effects of voltage, oxidation time, concentration of Cl , and temperature on degradtaion of organic pollutant were studied. The experimental results showed that under the condition of voltage 3.5V, density of current 7.0 mA/cm2, oxidation time 2.5h, and concentration of Cl 2000mg/l, CODCr of landfill leachate could be reduced from 464mg/L to 200mg/L. The removal rate of NH3-N was larger than 95%.
