摘　　要：概述了乙酸钠促进微生物共代谢,乙酸钠促进微生物胞内聚合物和胞外聚合物生成,改善活性污泥絮凝沉降性的相关研究。记录了石化污水处理场A/O生化装置工业案例,如乙酸钠将该装置处理含硫化物污水的COD去除率从89.68%提高到91.51%;处理含油污水的COD去除率从88.08%提高到90.22%;处理低碳氮比污水的COD去除率从85.68%提高到90.83%的现象,以期为同行业污水处理管理提供借鉴。This paper summarized the relevant study on microbial co-metabolismpromoting bysodium acetate, the formation of intracellular and extracellular polymerspromoting bysodium acetate, and improvement of the flocculation and sedimentation of activated sludge,recorded the industrial cases of A/O biochemical plant in petrochemical wastewater treatment plant. For example,sodium acetate increased the COD removal rate of sulfide wastewater treatment plant from 89.68% to 91.51%. The removal rate of COD from oily wastewater increased from 88.08% to 90.22%. The COD removal rate of low carbon nitrogen ratio wastewater was increased from 85.68% to 90.83%, in order to provide reference for the same industry wastewater treatment management.
