| 摘 要： | 采用Fe/C微电解和Fe/C微电解-Fenton氧化联合工艺对垃圾渗滤液进行处理,研究了废水初始pH、药剂投加量、药剂投加比例和反应时间等对处理效果的影响,获得Fe/C微电解处理垃圾渗滤液的最佳工艺条件:初始pH=3、m(Fe)/m(C)为4、ρ(Fe/C)为0.6 g/L、反应时间为60 min,处理后COD降至5 960 mg/L,COD去除率达51.8%。Fe/C微电解-Fenton氧化处理垃圾渗滤液的最佳工艺条件:在Fe/C微电解最佳条件下,H2 O2投加量为11 mL/L,反应时间为100 min,出水COD为4 480 mg/L,COD总去除率为63.8%。垃圾渗滤液中的腐殖酸类有机质经过Fe/C微电解或微电解-Fenton氧化处理后变成小分子产物,与Fe/C微电解相比,Fenton氧化对腐殖酸等大分子有机质有更强的氧化降解效果。

| Abstract: | Iron-carbon microelectrolysis and its Fenton process were used to treat landfill leachate.The factors,such as pH,reagent dosage,reagent ratio,and reaction time were investigated.The landfill leachate COD decreased to 5 960 mg/L and COD removal reached 51.8% after iron-carbon microelectrolysis under the optimal conditions of initial pH value of 3,iron to carbon mass ratio of 4,iron-carbon dosage of 0.6 g/L,and reaction time of 60 min.The optimal operating conditions of iron-carbon microelectrolysis-Fenton pr... |
