应用液相催化复极性流化床电解槽降解处理对硝基酚废水.溶液中的Fe2+离子与O2在阴极还原生的成H2O2形成了Fenton试剂,实验以对硝基酚为降解底物,考察了槽电压、Fe2+浓度及曝气量对模拟废水对硝基酚及COD去除率的影响.结果显示,在pH=3.0,电压30V,Fe2+浓度500 mg.L-1,曝气量0.4 m3.h-1的条件下,对硝基酚及COD均有较高的去除率.
This investigation was performed to study the degradation of p-nitrophenol(PNP) in the bipolar liquid bed cell catalyzed by liquid phase.The hydrogen peroxide produced on cathodes with the ferrous generated Fenton's reagent to produce hydroxyl radicals which are very active toward organic compounds to strengthen bipolar liquid bed cell in disposing organic compounds.The effects of cell voltage,ferrous concentration and airflow on the COD and PNP removal efficiency were also studied.When pH=3.0,cell voltage is 30V,ferrous concentration is 500×10~(-6) and airflow is 0.4 m~(3)/h,higher removal efficiency of the COD and PNP are obtained.
