| 摘 要： | 采用Fenton试剂氧化处理兰炭废水,通过考察各影响因素对COD及色度的去除率,确定最佳工艺条件。结果为:温度为60℃,pH值为6,H_2O_2投加量为0.3 mol,n(Fe~(2+)):n(H_2O_2)=20,反应时间为120 min,对COD和色度的去除率最大,分别为96.84%和98.00%,B/C值由0.21上升到0.60,可生化性得到很大提高。

| Abstract: | Semi-coking waste water was treated by Fenton's reagent. The optimal conditions were determined by studying the effect of factors on COD and chroma removal rate. The results show that, when the pH value is 6,the dosage of H2O2 is 0.3 mol, the molar concentration ratio of H2O2/Fe2+ is 20 and the reaction time is 120 min, the reaction temperature is 60 ℃, the removal rate of COD and chroma is biggest, and can reach to 96.84% and 98.00%respectively, the B/C value can increase from 0.21 to 0.60, and the biodegradability of semi-coking waste water can been greatly improved. |
