摘　　要：采用Fe2+诱导H2O2-O3,进行了内分泌干扰物邻苯二甲酸二甲酯(DMP)的降解试验。结果表明,Fe2+的存在消除了H2O2对臭氧的抑制作用,并使得H2O2-O3对DMP的氧化作用提高了31.75个百分点。当溶液DMP的初始质量浓度为50 mg.L-1、温度为60℃、初始pH为10、H2O2投加量为49 mmol.L-1、O3投加量为1.82 g.h-1、Fe2+投加量为0.72 mmol.L-1时,反应45 min的条件下,Fe2+-H2O2-O3对DMP的去除率可达到78.32%。One kind of Endocrine disrupting compounds-Dimethyl phthalate（DMP） was degraded by H2O2-O3 system under the induction of Fe2＋.The research indicated： the H2O2 restrain action to O3 was eliminated because of the existence of Fe2＋.Meanwhile,the removal efficiency of DMP was improves 31.75% by Fe2＋-H2O2-O3 system.After 45 min,The removal rates of DMP reach 78.32% by Fe2＋-H2O2-O3 system when conditions were as follows： the initial concentration of DMP was 50 mg·L-1,the temperature of reactor was 60 ℃,the pH of model solution was 10,the dosage of H2O2 was 49 mmol·L-1,the flow rate of O3 was 1.82 g·h-1 and the dosage of Fe2＋ was 0.72 mmol·L-1.
