氧化铈-钒酸铁/凹土对染料废水脱色处理

Decolorization of Dye Wastewater by CeO_2-FeVO_4/Attapulgite

把凹土作为载体来制备对废水进行脱色的催化剂,是现在废水脱色处理研究的热点。将CeO_2-FeVO_4/ATP和H_2O_2组成非均相类Fenton体系对红色基GP染料废水进行脱色研究。主要考察研究CeO_2-FeVO_4/ATP的加入量、脱色时间、脱色温度、pH值以及H_2O_2用量对染料废水脱色率的影响。实验结果表明:在CeO_2-FeVO_4/ATP的加入量为2 g/L,脱色时间为1 h,pH值为6,脱色温度为313 K,H_2O_2用量为9 mL/L时脱色率达到99%。

By treating attapulgite as carrier to prepare the catalyst for the decolorization of is a hot spot in the research of wastewater treatment.Decolorization rate of red dye wastewater was investigated using CeO_2-FeVO_4/ATP and H_2O_2 reagents.Various influencing factors on the decolorization rate were examined,such as CeO_2-FeVO_4/ATP dosage,pH value,reaction temperature,H_2O_2 dosage.Experimental results show that,when When CeO_2-FeVO_4/ATP dosage is 2 g/L,the adsorption time is 1 hour,pH value is 6,reaction temperature is 313 K,H_2O_2 dosage is 9mL/L,it showed us that decolorization rate reached99%.
