摘　　要：通过实验考察了不同无机离子对三维电极体系耦合电-Fenton法处理苯胺废水效果的影响。实验发现适当浓度的Fe3+可促进苯胺的降解,Mn2+、S2-、CO32-、H2PO4-、Cl-则在一定程度上抑制了苯胺降解。NO3-对降解苯胺的影响并不明显。实际工程中,可根据不同无机离子对Fenton法影响程度,采取相应的预处理措施,保证苯胺废水处理效果。Effects of different inorganic ions on the treatment of aniline wastewater by coupling electro-Fenton in three-dimensional electrode system were investigated.The results showed that the proper concentration of Fe3+could promo-te the degradation of aniline,while Mn2+,S2-,CO32-,H2PO4-and Cl-could inhibit the degradation of aniline.However,the effect of NO3-on the degradation of aniline was not obvious.According to the influence degree of different inorga-nic ions on the Fenton method,the corresponding pretreatment measures could be taken to ensure the treatment effect of aniline wastewater in practical engineering.
