摘　　要：针对抗生素制药废水组分复杂难降解、COD浓度高、可生化性差等特点,采用铁碳微电解-H2O2耦合工艺对抗生素制药废水进行预处理,研究分析了初始pH值、铁碳质量比及其投加量、H2O2投加量、气水比和反应时间对废水处理效果的影响。结果表明,在初始pH值为3、铁碳质量比为1∶1、铁碳投加量为100 g/L、H2O2(30%)投加量为30 mL/L、气水比为30∶1、反应时间为100 min的最佳工艺条件下,铁碳微电解-H2O2耦合工艺对抗生素制药废水预处理效果良好,出水COD、BOD5去除率分别为38.43%和20.40%,m(BOD5)/m(COD)值由0.107提升至0.233,废水可生化性得到提高。In view of the characteristics of antibiotic pharmaceutical wastewater such as:complex components,hard to be degraded,high COD concentration,poor biodegradability and so on,the process of iron-carbon micro-electrolysis coupled with H2O2 was adopted for its pretreatment.The influence of initial pH value,iron-carbon mass ratio and its dosage,H2O2 dosage,gas-water ratio,and reaction time on wastewater treatment effect were studied and analyzed.The results showed that,under the optimal condition that the initial pH value was 3,the mass ratio of iron to carbon was 1∶1,the iron-carbon dosage was 100 g/L,the H2O2(30%)dosage was 30 mL/L,the gas-water raito was 30∶1,the reaction time was 100 min,the treatment effect of antibiotic pharmaceutical wastewater by the said coupling process was good,the removal rates of COD and BOD5 in the effluent water were 38.43%and 20.40%respectively,the m(BOD5)/m(COD)value increased from 0.107 to 0.233,the biodegradability of the wastewater was improved.
