中文摘要:
      研究采用Fe/C微电解-Fenton法对老龄城市生活垃圾渗滤液进行预处理,提高其可生化性.通过调整初始pH,Fe-C投加量,铁碳质量比,H2O2投加量及反应时间考察其对垃圾渗滤液处理的效果,同时对Fe/C微电解,Fenton以及Fe/C微电解-Fenton的处理效果进行对比研究.实验结果表明,Fe/C微电解-Fenton法预处理表现出最好的处理性能,其最佳处理条件为:初始pH 3,Fe-C投加量 52 g/L,Fe/C 3,H2O2投加量12 mL/L,接触反应1 h后,COD去除率达到75%.此外,渗滤液的BOD5/COD也从0.075提高到0.250.
英文摘要:
      Iron-carbon microelectrolysis with Fenton process was used to pretreat the mature landfill leachate and to enhance its biodegradability.The factors, such as initial pH, iron-carbon concentration, the mass ratio of iron to carbon, dosage of H2O2 and reaction time were investigated. Under the optimal conditions of initial pH of 3, iron-carbon concentration of 52 g/L, iron to carbon mass ratio of 3, H2O2 dosage of 12ml/L, the removal efficiency of COD reached 75% after a reaction time of 1 h. The ratio of BOD5 to COD also increased from 0.075 to 0.250, which suggested that iron-carbon microelectrolysis with Fenton process could significantly improve the biodegradability of landfill leachate, compared with the single iron-carbon microelectrolysis or Fenton process.
