曝气生物滤池深度处理染料废水的研究

Study on Advanced Treatment of Dyestuff Wastewater with Biological Aerated Filter

染料废水是典型的难生物降解工业废水,实验以经过二级处理的低浓度染料废水作为原水,采用由陶粒—活性炭为填料构成的两段式曝气生物滤池对其进行深度处理,当气水比为2∶1时对SS、色度、CODCr和NH+4N的平均去除率分别达到71.1%、92%、48.1%和86.3%。

Dyestuff wastewater is typical refractory industrial wastewater. In this study,low concentration dyestuff wastewater was treated by two-stage BAF which is filled with ceramic granule and activated carbon. The average removal rate of SS,color,CODCr and NH4^＋-N reaches 71.1% ,92% ,48.1% and 86.3% respectively under the condition of the air-to-liquid ratio equal to 2 ： 1.
