摘要
采用Fenton氧化和粉煤灰吸附两级工艺,研究其对造纸厂废水处理的效果。结果表明,在pH值为3,H2O2投加量为2.5mL/L,FeSO4投加量为150mg/L时,Fenton氧化对废水COD的去除率达86%,色度去除率达90%。粉煤灰的投加量为300g/L,吸附时间为3h,COD的去除率可达68%。
<Abstrcat>Two stage process of Fenton oxidation and fly ash absorption are used to study the result of paper-making wastewater treatment.In condition of pH 3,H_2O_2 dosage 2.5 mL/L.FeSO_4 dosage 150 \{mg/L\},86% of COD removal ratio and 90% of discoloring ratio are achieved by Fenton oxidation treatment on wastewater,fly ash dosage 300 g/L,absorption time 3 h,68% of COD removal ratio is achieved.
