Treatment of Acrylic Fiber Polymerization Wastewater by Fenton Method

  • 摘要: 采用Fenton法处理腈纶聚合废水,考察药剂、反应条件等对处理效果的影响,并分析了其作用机理,确定了反应过程中的关键控制因素. 结果表明:Fenton法处理腈纶聚合废水时,影响CODCr去除率的因素依次为c(H2O2)>反应时间>pH>c(Fe2+);最佳试验条件〔c(H2O2)为0.2 mol/L, c(Fe2+)为28.8 mmol/L, pH为2.5, 反应时间为150 min〕下处理腈纶聚合废水时,进水ρ(CODCr),ρ(BOD5)和ρ(丙烯腈)分别为1 200.0,242.1和97.4 mg/L,出水分别为301.6,110.0和0 mg/L,去除率分别为74.9%,55.0%和100.0%,ρ(BOD5)/ρ(CODCr)由0.2提高到0.36,废水可生化性显著提高,特征污染物丙烯腈得到有效去除.
