Charactristics of Fenton Process in Advanced Treatment of Acrylic Fiber Wastewater

  • 摘要: 研究Fenton法深度处理难降解腈纶废水的影响因素及其优化反应条件,应用紫外和三维荧光光谱探讨腈纶废水生化出水中污染物的去除规律. 研究表明:初始pH由1.5升至6.0时,CODCr去除率由20.0%快速升至61.8%后再缓慢降至51.0%;c(Fe2+)由0.8 mmol/L增至10.8 mmol/L时,CODCr去除率先由2.5%增至58.0%再缓慢降至55.5%;c(H2O2)和反应时间对CODCr去除率影响较小. 正交试验极差表明,CODCr去除率的影响因素为初始pH>c(Fe2+)>c(H2O2)>反应时间,最优条件〔c(Fe2+)为7.20 mmol/L、c(H2O2)为0.16 mol/L、初始pH约为3、反应时间为90 min〕下腈纶废水生化出水ρ(CODCr)由308 mg/L降至103 mg/L,去除率为66.5%. 紫外和三维荧光光谱显示,腈纶废水生化出水中的类蛋白类物质完全被去除,大部分可见腐殖质类物质以及UV腐殖质类物质也被分解.
