【摘要】 采用有机膨润土吸附处理后进行电Fenton氧化法处理垃圾渗滤液,可以有效降低垃圾渗滤液中COD的含量,提高垃圾渗滤液的可生化性,为后续生化处理创造较好的实验条件。实验结果表明:有机膨润土吸附处理垃圾渗滤液,COD去除率为49.56%。有机膨润土吸附后进行电Fenton最佳实验,Fe²⁺浓度为3mol/L;pH值为3;温度为30℃;电压为7V,此时COD去除率为81.23%,可生化性由0.19上升到0.42,满足后续生化处理的要求,达到实验处理目的。更多还原

【Abstract】 Treatment of landfill leachate by electro-Fenton oxidation after adsorption of organic bentonite,It can effectively reduce COD content in landfill leachate,Improvement of biodegra dability of landfill leachate,Create better experimental conditions for subsequent biochemical treatment.The experimental results show that:Adsorption treatment of landfill leachate by Organobentonite,COD removal rate was 49.56%.The best experiment of electro Fenton for organobentonite adsorption,Fe²⁺concentration is 3mol/L;The pH value is 3;Temperature is 30℃;Voltage is 7V,At this time,the removal rate of COD was 81.23%.Biodegradability increased from 0.19 to 0.42,To meet the requirements of follow-up biochemical treatment,To achieve the purpose of experimental treatment.更多还原
