微电解-Fenton净化对氨基苯酚废水研究

Purification of p-aminophenol wastewater by micro electrolysis Fenton process

采用微电解工艺及微电解-Fenton工艺处理对氨基苯酚废水。结果表明,处理200 mL浓度为0.5 g/L对氨基苯酚废水,单独微电解工艺,在pH为3,废铁屑投加量50 g/L,铁炭质量比为20∶1,反应60 min,COD和色度去除率分别为40.25%和42.28%。微电解-Fenton联用,在pH为3,铁炭质量比为20∶1,双氧水投加量30 mL/L,反应60 min,COD和色度去除率分别达到93.72%和95.7%。

This paper deals with the treatment of p-aminophenol wastewater by micro electrolysis and micro electrolysis Fenton process.The results show that treatment of 200 mL,the concentration of 0.5 g/L p-aminophenol wastewater,the removal rate of COD and chroma is 40.25%and 42.28%,respectively,when the pH is 3,the dosage of scrap iron is 50 g/L,the ratio of iron to carbon is 20∶1,the reaction time is 60 min.When the pH was 3,the mass ratio of iron to carbon was 20∶1,the dosage of hydrogen peroxide was 30 mL/L,the reaction time was 60 min,the removal efficiency of COD and chroma was 93.72%and 95.7%respectively.
