Abstract:

Crythromycin wastewater is treated in an anaerobic fluidized bed reactor (AFB) with granular activated carbon as carrier, operating at 33- 35 ℃. The operating characteristic is studied. The test result demonstrates that the removal efficiency of COD and BOD are 76.6% and 65.9% respectively as influent COD is 6 900 mg/L and HRT is 4.4 h. The non-biodegradation organism concentration is obtained by Garrett - Sawyer formula. And the degradation equation for the anaerobic digestion of crythromycin wastewater is concluded by employing the Monod model.

Key words: crythromycin wastewater, wastewater treatment, anaerobic fluidized bed

摘要：

研究了中温(33～35℃)条件下,厌氧流化床(AFB)反应器处理红霉素废水的运行特性。结果发现:进水COD为6 900 mg/L、HRT为4.4 h时,COD、BOD的去除率分别达到了76.6%、65.9%。最后利用Garrett-Sawyer关系式求出了难生物降解的有机物浓度,并利用Monod模型对实验结果进行了动力学分析,得出了红霉素废水中温条件下厌氧消化过程的基质降解规律。
