悬浮填料生物膜A/O法处理石化废水试验研究

Study on the treatment of petrochemical wastewater by using suspended filler biofilm A/O process

介绍了将悬浮填料生物膜A/O法用于石油化工废水处理的研究 ,结果表明 ,在水力停留时间为 8h ,回流比为 10 0 %条件下 ,对石油化工废水中COD、NH3 -N、TN的平均去除率分别为 81%、94%、5 7.3% ,出水水质达到国家规定排放标准。在试验基础上研究并探讨了该A/O法的工艺特性 。

The treatment of petrochemical wastewater by using suspended filler biofilm A/O process is introduced. The results show that the process has a high removal efficiency of COD Cr 81%、NH 3-N 94%、TN 57.3% under the conditions of HRT 8 h, R 100%. The effluent quality is stable and conforms to the national permitted criterion,the characteristics of the process is studied and discussed on the basis of experiments to provide experimental basis for its application to petrochemical wastewater treatment.
