| 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2.5 mL/L，FeSO4投加量为150 mg/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300 g/L，吸附时间为3 h，COD的去除率可达68%。 |

| Abstract: |
| 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,H2O2 dosage 2.5 mL/L.FeSO4 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. |
