摘　　要：通过向含铁水中投加二氧化氯和混凝剂,考察了二氧化氯对水中铁的去除效果及其影响因素。结果表明,二氧化氯投加量、原水pH、预氧化时间和混凝剂投加量对铁的去除效果均有较大的影响。当原水Fe2+浓度为5 mg/L时,二氧化氯最佳投加量为5 mg/L,最佳氧化时间为10 min,混凝剂的最佳投加量为1 mg/L,最佳pH值为7～9,对铁离子的去除率可达到94.0%。The removal of iron in raw water and its influencing factors were investigated by chlorine dioxide and coagulants. The result showed that the dosage of chlorine dioxide, pH of raw water, time of preoxidation and dosage of coagulants had significant influence on removal rate of iron. The removal rate was 94% with an initial concentration of iron 5 mg/L in the water, the optimum condition was a dosage of chlorine dioxide correspondingly 5 mg/L, a time of oxidation 10 min, a dosage of coagulant 1 mg/L, and pH value of 7 to 9.
