摘要
采用Fenton试剂氧化—SBR工艺处理阿莫西林制药废水生化处理出水。实验结果表明:当初始废水pH为3.0、H2O2加入量为10 mL/L、V(H2O2):m(FeSO4.7H2O)为5(mL):1(g)、Fenton试剂氧化反应时间为3 h时,Fenton试剂氧化COD去除率达72.25%,色度由100倍降为2倍,BOD5/COD由0.06提高到0.38,可生化性显著提高。经Fenton试剂氧化—SBR工艺处理后,出水COD为72.7 mg/L,达到国家排放标准。
Biotreated amoxicillin wastewater was treated by Fenton reagent oxidation-SBR process. The experimental results show that： When the wastewater pH is 3.0, the H202 dosage is 10 mL/L, V（H202） ： m（FeSO4.7H20）=5（mL） ： l（g） and the Fenton reagent oxidation time is 3 h, the COD removal efficiency of Fenton reagent oxidation process is 72.25%, the chroma is decreased from 100 times to 2 times, and BODJCOD is increased from 0.06 to 0.38, which indicates that the biodegradability of the wastewater is improved remarkably. After treated by the Fenton reagent oxidation-SBR process, the wastewater quality can meet the national discharge standard（COD 72.7 rag/L）.
