摘　　要：研究不同磁化时间、不同磁场强度以及催化氧化体系中各种影响因素对表面活性剂污水CODcr的去除率的影响。结果表明:在pH值3,H2O2加入量为0.5%(体积比),FeSO4.7H2O浓度为3 000 mg/L,反应10min,去除率达69.8%。在相同实验条件下,外加磁场强度分别为235.6 mT、357.3 mT、427.8 mT,CODcr的去除率可提高3.5%、8.4%、10.5%。This paper studied the removal effect on CODer of surfactant wastewater with Fenton reagent in the catalytic system with different magnetic reaction time and intensities. The results showed that the removed rate of CODor reached 69.8% under conditions of pH 3, H202 0. 5% , FeSO4 · 7H2O =3 000 mg/L and 10 min. Under the same conditions, magnetic intensity was respectively 235.6 mT, 357.3 mT, 427.8 inT. The removed rate of CODer was respectively 3.5%, 8.4% and 10. 5%, better than without magnetic field.
