【摘要】 对紫外光引发Fenton氧化技术协同处理造纸中段废水COD_Cr进行了研究，探究反应时间、FeSO₄·7H₂O浓度、H₂O₂浓度、p H值、紫外光强度等因素对COD_Cr去除效率的影响。实验结果表明，在反应时间80min,Fe SO₄·7H2O浓度0.6mol/L,H₂O₂浓度0.3 mol/L,pH值为4，以及紫外光强度为14 mW/cm²的最优条件下，该技术能够实现造纸中段废水74%的COD_Cr去除率。紫外光引发Fenton氧化技术能够有效促进Fenton氧化反应中·OH自由基的生成，提高造纸中段废水的COD_Cr去除效率。更多还原

【Abstract】 Through the investigation of the collaborative treatment of COD_Cr in papermaking wastewater by UV-induced Fenton oxidation technology,we explored the effects of reaction time,FeSO₄·7H₂O concentration,H₂O₂ concentration,pH value,UV intensity,and other factors on the removal efficiency of CODCr.The experimental results indicate that under the optimal conditions of reaction time of 80 min,FeSO₄·7H₂O concentration of 0.6 mol/L,H₂O₂ concentration of 0.3 mol/L,pH value of 4,and UV intensity of 14 mW/cm²,this technology can achieve a COD_Cr removal rate of 74%in papermaking wastewater.The UV-induced Fenton oxidation technology effectively promotes the generation of·OH free radicals in the Fenton oxidation reaction and improve the COD_Cr removal efficiency of papermaking wastewater.更多还原
