Fenton试剂处理印染废水最佳工艺条件研究

摘要

通过研究Fenton试剂处理印染废水的效果,确定最佳工艺条件。以1g/L的FeSO4和30%的H2O2处理印染废水,确定其最佳pH值,最佳H2O2和FeSO4投加量。结果表明,该法很适合作为成分复杂的印染废水的前处理,其最佳工艺条件是：最佳初始pH值为4;30%H2O2的最佳投入量是50mL/L;FeSO4的最佳投入量是20mg/L。最佳工艺条件下的CODcr及色度的去除率达到78.94%和98.50%,效果令人满意。%Dyeing wastewater was treated with Fenton agent to determine the optimal process conditions.The optimal process conditions were determined by using 1 g/L FeSO4 and 30% H2O2.The results show that the method is suitable for dyeing wastewater＇s pretreatment,
