摘　　要：研究了工程项目中，铁碳微电解-Fenton氧化组合工艺预处理头孢菌素废水的实际效果，在现场调试过程中采用单因素分析法确定了各参数的最佳反应条件值。结果表明，在高浓度废水COD为60～120gm、铁碳比为1：1、反应时间为100min、pH为3时，运用铁碳微电解可以对废水COD去除率达到30％左右；以铁碳微电解出水为基础，调节pH为2．5，H202（27．5％）投加量为20mL／L，FeSO4·7H2O（10％）投加量为22gm，反应时间为60min，在室温下对原水的COD去除率在65％左右。BOD5/COD也由原来的不足0．24提升到了0．35左右，提高了废水的可生化性。The combined process of ferric-carbon micro-electrolysis and Fenton oxidation was studied in the pretreatment of cephalosporin wastewater in practical projects. During commissioning, the single factor analysis method was adopted to determine the optimum reaction conditions for each parameter. Results showed that when the COD in influent was 6-120 g/L, ferric/carbon ratio was l：l, the reaction time was 100 min and pH was 3, the removal rate of COD was about 30%. When the pH was 2.5, the dosage ofH202（27.5%） was 20 mL/L, the dosage of FeSO4.7H20（10%） was 22 g/L, and the reaction time was 60 min, the removal rate of COD was about 65% in raw wastewater through Fenton oxidation. BOD5/COD also rose from less than 0.24 to 0.35 and this process had effectively improved the biodegradability ofwastewater.
