  • 摘要: 以高炉瓦斯泥为铁源,通过其在酸性条件下与H2O2 形成Fenton/类Fenton反应体系来处理硝基苯废水,考察了pH、H2O2用量、高炉瓦斯泥用量及反应时间对硝基苯降解率的影响,并对降解机理进行了分析表征。实验结果表明,在pH为3、高炉瓦斯泥用量为0.5 g/L、H2O2用量为10 mL/L、反应时间为60 min的条件下,100 mg/L的硝基苯溶液中硝基苯的降解率达87.88%;硝基苯先被氧化生成硝基苯酚、硝基苯二酚、对苯醌等中间产物,然后再进一步氧化生成二氧化碳和水达到降解的目的。
    Abstract: The blast furnace sludge with ferrous and ferric ions can react with hydrogen peroxide to form Fenton reaction system/Fenton's type reaction system under an acidic solution,so it can be used to treat the nitrobenzene wastewater.Effects of pH,H2O2 dosage,blast furnace sludge dosage and reaction time on nitrobenzene degradation rate were discussed,and the mechanism of degradation was also characterized.The experimental results show that the degradation rate of 100 mg/L nitrobenzene solution can reach 87.88% under the conditions of pH=3,the dosage of the blast furnace sludge=0.5 g/L,the dosage of H2O2=10 ml/L and reaction time=60 min.Nitrobenzene was first degraded into nitrophenol,nitrobenzene hydroquinone,p-benzoquinone,and then further oxidized into CO2 and H2O in the degradation process.
