摘　　要：实验采用混凝-Fenton氧化预处理抗生素废水,筛选出最佳的混凝条件及氧化条件,同时对经混凝-Fenton试剂预处理后的废水与未经处理的废水按同样反应条件开展好氧生化试验。实验发现,采用聚合氯化铝(PAC)和聚丙烯酰胺(PAM)复合混凝处理该废水,在pH为8,PAC与PAM的用量分别为400mg/L和12mg/L时混凝效果较好。混凝后的废水再用芬顿体系氧化,当pH为3,FeSO·47H2O投加量为0.01mol/L,H2O2/Fe2+摩尔比4:1下,反应30min时,取得了满意的结果。实验表明,采用混凝-芬顿氧化法预处理抗生素废水后,明显改善了其可生化性,为后续生化处理打下了良好的基础。Process of coagulation-Fenton oxidation was used to treat antibiotic wastewater,and the best condition of coagulation and oxidation was selected.Under the conditions of pH 8,the effect of the coagulating treatment of wastewater was better when PAC and PAM were used as coagulants with the feeding amount of 400mg/L and 12mg/L respectively.When pH was equal to 3,the wastewater treated above was oxidized by H2O2/Fe2+.Under the feeding amount of FeSO4·7H2O 0.01mol/L,H2O2:Fe2+ 4:1 and reaction time 30min,the trea...
