摘    要:针对我国垃圾渗滤液成分复杂,处理技术不成熟等问题,采用电化学氧化的方法对含高氨氮的模拟垃圾渗滤液废水进行了实验研究。研究了不同的阳极材料,电流密度和氯离子质量浓度对氨氮的去除效果的影响。结果表明,在采用TiO2/SnO2阳极,电流密度20 mA/cm2,氯离子质量浓度10 g/L的条件下,氨氮的去除率可达到95%。在反应过程中,氨氮的去除符合准零级反应动力学。在最优条件下采用电化学氧化法处理实际的垃圾渗滤液,结果发现,反应240 min后,废水中的氨氮也可得到全部去除,色度的去除率可达82%。该方法用于成分复杂的垃圾渗滤液的脱氮处理具有较好的应用前景。

关 键 词:氨氮  电化学氧化  垃圾渗滤液  余氯  氯离子质量浓度  电流密度

Abstract:The treatment of electrochemical oxidation for simulated leachate with high ammo-nia concentration was investigated to develop a practicable and feasible technology , as the characteristic of landfill leachate was complicated and the available treatment was not enough to solve this problem .The influence of anode materials , current density and chloride concen-tration on ammonia removal was investigated .The results demonstrated that ammonia removal efficiency in electrochemical oxidation system could reach 95% under the condition of 20 mA/cm2 current density, 10 g/L chloride concentration and TiO2/SnO2 as anode.Ammonia removal followed pseudo zero -order kinetics .All ammonia in landfill leachate could be re-moved and the color removal efficiency could reach 82%after 240 min electrolysis under the optimal condition .This electrochemical oxidation technology was potential to further larger -scale application on ammonia removal in landfill leachate .
Keywords:ammonia  electrochemical oxidation  landfill leachate  chlorine  chloride con-centration  current density
