摘　　要：阐述某石化污水处理场投加乙酸钠提高A/O生化脱氮除碳效率的必要性,介绍了该污水场投加乙酸钠,使A/O生化TN去除率从75.95%上升至90.15%,COD去除率从91.03%上升至91.94%,A/O出水COD从59 mg/L下降至46.7 mg/L,污水场电耗、剂耗下降的案例,为石化污水处理场A/O生化工艺的优化运行提供借鉴。This paper described the necessity of adding sodium acetate in a petrochemical wastewater treatment plant to improve the efficiency of A/O biochemical denitrification and decarbonization and introduced that,the A/O biochemical TN efficiency increased from 75.95%to 90.15%and COD from 91.03%to 91.94%by adding sodium acetate,the A/O effluent COD decreased from 59 mg/L to 46.7 mg/L,and the power consumption and agent consumption of wastewater treatment plant decreased,which provided reference for the optimization operation of A/O biochemical process in petrochemical wastewater treatment plant.

关 键 词：乙酸钠 COD去除率 TN去除率 A/O
