摘要： 针对阿奇霉素废水高COD、高氨氮浓度、高色度以及高含盐量的特点，采用吹脱-铁炭微电解-Fenton氧化预处理阿奇霉素废水，效果良好。试验结果表明：吹脱pH值为11～12、吹脱时间20 h时，氨氮去除率达到80%；铁炭微电解pH值为3～4、铁炭比为1.5、反应时间为80 min时，COD去除率达到45%；向微电解出水投加30 mL/L的H₂O₂（质量分数为30%）进行Fenton氧化处理，COD去除率提高到89.6%。预处理后，废水的BOD₅/COD从0.18提高到0.3，提高了废水的可生化性。

Abstract:

Air stripping–Fe-C microelectrolysis–Fenton oxidation process was used to treat the azithromycin waste water with characteristics of high COD，high ammonia，heavy color，as well as high salt content，and a good result was obtained. The experimental results indicated that the removal rate of the ammonia nitrogen reached 80% by air stripping when pH value was 11 to 12，stripping time was 20 h. When the reaction time for the microelectrolysis was 80 min and pH was 3 to 4，the removal rate of COD reached 45%. When the dosage of H2O2 (mass fraction 30%) to the microelectrolysis effluent was 30 mL/L，the removal rate of COD was increased to 89.6% by Fenton oxidation. After pretreatment of waste water，BOD5/COD was increased from 0.18 to 0.3，and the biodegradability of waste water was improved obviously.
