摘要
利用Fenton试剂反应氧化处理含酚和甲醛废水,讨论了不同Fe2+溶液和H2O2溶液的初始投加比、温度、pH值对Fenton试剂氧化降解含酚和甲醛废水的影响。结果表明,浓度为100mg.L-1 Fe2+溶液与30%的H2O2溶液用量体积投加比为8,温度为65℃,pH=3.29时,苯酚和甲醛的降解效果较好。在最优化条件下,人工模拟废水中苯酚和甲醛的降解率可达到90%以上,处理效果较好,为工业废水的现场处理过程提供了一定的理论基础。
The paper described the use of Fenton reagent in the oxidation treatment of phenol and formaldehyde in wastewater.The influences of different dosage ratio of initial concentration Fe2＋and H2O2 solution,temperature,pH,to the degradation of phenol and formaldehyde in wastewater were discussed.The results showed that the optimized conditions were dosage ratio of the 100 mg·L-1 Fe2＋ solution and 30% H2O2 solution of 8,temperature of 65 ℃,pH of 3.0,the removal rate of phenol and formaldehyde were better.In this environment,the removal rate of phenol and formaldehyde could reach up to 90%.This study provided more information to the treatment process of industrial wastewater.
