摘要
利用粉末活性炭(PAC)强化A/O工艺(PAC—A/O)与传统A/O工艺对高含盐难降解实际工业废水处理进行对比研究。结果表明,PAC—A/O工艺较A/O工艺具有更好的去除有机物和脱色效果,稳定运行期间,对COD的平均去除率提高16%,对色度的平均去除率提高25%。进一步研究发现,PAC—A/O工艺处理效果优于A/O工艺的重要原因,在于投加PAC使得系统内生物量增加、污泥沉降性以及污泥比耗氧速率得到明显改善。
A comparison was made between PAC treat a high-salinity refractory industrial wastewater. The superior to the traditional A/O process in COD COD and color in the PAC -A/O process were -A/O process and traditional A/O process to results showed that the PAC -A/O process was removal and decolorization. The average removal rates of greater than those in the traditional A/O process by 16% and 25% , respectively. PAC addition increased biomass ic oxygen uptake rate. and improved sludge settleability and the specif-ic oxygen uptake rate.
