摘要：

先用混凝+水解酸化法预处理抗生素废水,再用序批式活性污泥反应器(SBR)₊一体化膜生物反应器(MBR)进行生化处理。结果表明:废水经混凝处理后,COD_Cr平均去除率达33.72%,水解酸化预处理后,COD_Cr平均去除率达到17.25%,可生化性提高;经SBR+MBR组合好氧工艺处理后,COD_Cr由平均进水1 200 mg/L降至出水195mg/L左右(≤300 mg/L),达到国家污水综合排放标准(GB 8978-1996)二级指标。

Abstract:

Coagulation-hydrolytic acidification process has been used for the pretreatment of antibiotic pharmaceutical wastewater. Then，SBR+MBR process has been used for treating the wastewater biochemically. The running results show that its COD_Cr average removal rate reaches 33.72%， after the coagulating treatment. The COD_Cr removal rate reaches 17.25%， and biodegradability is improved after hydrolytic acidification. Finally，the average effluent COD_Cr drops from 1 200 mg/L to 195 mg/L（≤300 mg/L） after being treated by the combined SBR+MBR aerobic process，which meets the 2nd class of the National Standard of Integrated Wastewater Discharge（GB 8978-1996）.

Key words: antibiotic pharmaceutical wastewater, pretreatment, coagulation, hydrolytic acidification
