摘要
高级氧化+BBR/A+BBR/O+BAF满足含盐污水深度处理COD及TN达标排放工艺,具有投资少、耗能低等优点。主要阐述了此污水处理工艺应用于石化企业含盐污水深度处理的试验情况。试验结果表明,臭氧对污水COD的去除起着关键作用,臭氧对污水COD的去除率平均可以保持在30%左右。BBR/A阶段对污水TN的去除起着关键作用,BBR/A池对总氮的去除率达到了60%。
Advanced-oxidation+BBR/A+BBR/O+BAF process can meet the demand for deep treatment of saline wastewater, and COD and TN indexes of treated wastewater can reach the discharge standards. It has the advantages of low investment and low energy consumption. In this paper, application of this wastewater treatment process in advanced treatment of saline wastewater in petrochemical enterprises was mainly described. The experimental results show that ozone plays a key role in the removal of COD from sewage, and the removal rate of COD from sewage can be maintained at about 30% on average. BBR/A stage plays a key role in the removal of TN from wastewater. The removal rate of TN by BBR/A tank reaches 60%.
