| 摘 要： | 利用花生壳耦合Fenton氧化技术对次甲基蓝废水处理工艺进行了研究。结果显示:花生壳吸附法对次甲基蓝的脱色效果比去除效果好。而耦合工艺对次甲基蓝的去除效果比脱色效果好。最佳耦合工艺条件为:对于250 mL 100 mg/L的废水,当花生壳投加量为3 g时,pH=5,FeSO4.7H2O浓度为1.0 g/L,H2O2=3 mL时去除效果较好。随着反应时间的增加,去除率几乎不变,但是脱色效率降低。当FeSO4.7H2O和H2O2过量的时候,对色度的去除有较强的抑制作用。 |

| Abstract: | Using peanut shell coupled Fenton oxidation for degradation methylene blue wastewater treatment process was studied. The results showed： methylene blue decoloration rate was better than removal rate in peanut shell adsorption process. While the methylene blue remove rate was better than decoloration rate. Optimum conditions： for the 250 mL 100 mg/L wastewater, when the peanut shell dosage is 3 g, pH was 5, FeSO4·7H2O concentration was 1.0 g/L, H2O2 volume was 3 mL had good removal and decoloration rate. With the increase of time, removal efficiency almost unchanged, but the decoloration decreased. When FeSO4·7H2O and H2O2 overdose, while the color removal had a stronger inhibitory effect. |
