| 摘 要： | 采用UV/FeEDTA/H2O2体系在碱性条件下降解2,4-二氯苯酚废水,探讨了pH值,H2O2,FeEDTA以及2,4-二氯苯酚初始浓度等因素对其去除率的影响。结果表明,碱性条件下对250mg/L的2,4-二氯苯酚废水,最佳处理条件如下:pH=8,H2O2]=20mmol/L,FeEDTA]=1mmol/L,此条件下,反应50min后,2,4-二氯苯酚的去除率高达99.6%。

| Abstract: | The treatment of refractory 2, 4-dichlorophenol by UV/FeEDTA/H2O2 under basic conditions was studied to analyze the impact factors of pH, H2O2, FeEDTA and initial concentration on the removal efficiency of 2, 4-dichlorophenol. Results showed that treatment of 2, 4-dichlorophenol wastewater was under the optimal operating conditions: pH value of 8, suitable dose of H2O2 and FeEDTA 20mmol/L and 1mmol/L respectively. The removal efficiency of 2, 4-dichlorophenol was up to 99.6% after reacting for 50min with initial concentration 250mg/L. |
