摘　　要：采用Fe/C微电解-Fenton氧化-生化组合工艺处理抗生素生产废水,Fe/C微电解单元主要讨论了铁炭体积比、HRT、pH曝气量大小对处理效果的影响;Fenton氧化单元主要讨论了H2O2投加量、pH、HRT对处理效果的影响;混凝沉淀和生物接触氧化处理主要讨论了pH和HRT对各自处理效果的影响。结果表明,在最佳试验参数条件下,废水的色度、COD总的去除率分别为99.93%和99.73%,最终出水色度≤10倍,COD≤50 mg·L-1。The ferric-carbon electrolysis-Fenton oxidation-coagulation sedimentation-biological contact oxidation combined process was used to treat the antibiotic wastewater.The effect of the volume ratio of ferric to carbon,HRT,pH and aeration rate on the treatment efficiency of wasterwater was discussed in the ferric-carbon electrolysis unit; the effect ofpH, dosing quantity of 30% H2O2,HRT on the treatment efficiency of wasterwater in the Fenton oxidationunitwasdiseussed, meanwhile, theeffect ofpH on the treatment effciency of coaguoation sedimentation and the effect of HRT on thetreatment efficiency of biological contact oxidation were discussed.The results showed that, operated with the optimum parameters,the total chroma removal efficiency andCODremoval efficiency can reach 99.93% and 99.73%, and the effluent chroma and COD can be less than 10（times） and 50 mg·L^-1 respectively.
