铁炭微电解-H_2O_2法降解二甲基甲酰胺废水

Degradation of dimethylformamide wastewater by iron-carbon microelectrolysis combined with H_2O_2

采用铁炭微电解-H2O2法降解二甲基甲酰胺(DMF)废水,探讨了反应时间、pH、铁炭质量比(简写为Fe/C)以及H2O2投加量对DMF去除率的影响。结果表明:(1)当反应时间为60min、pH为3、Fe/C为3∶1时,DMF去除率为73.4%。(2)向反应体系中投加H2O2,DMF去除率明显提高。当H2O2投放量为0.20mL/L时,DMF去除率达到95.2%。

The iron-carbon microelectrolysis combined with H2O2 was performed on dimethylformamide（DMF） wastewater to determine the effect of reaction time,pH,iron/carbon mass ratio（Fe/C） and H2O2 dosage on DMF removal.The results showed that when pH was 3,Fe/C was 3∶1 and reacted for 60 min,the DMF removal rate reached to 73.4%.The DMF removal rate was greatly increased after adding certain content of H2O2,when the H2O2 dosage was 0.20 mL/L,the DMF removal rate increased to 95.2%.
