摘　　要：维生素原料药生产废水的水质波动大,有机负荷高,浓度高,降解难度较大。以湖北某大型维生素制药企业的废水处理工艺系统改造为例,介绍了厌氧膨胀颗粒污泥床(EGSB)-A^(2)O工艺的运行优化情况。改良后的EGSB反应器污泥平均粒径为2~2.6 mm,污泥流失率降到10%左右。系统最终出水水质达到《化学合成类制药工业水污染物排放标准》(GB 21904—2008),处理费用为4.81元/m^(3)。The vitamin pharmaceutical wastewater is difficult to degrade, due to great fluctuations in water quality, high organic load, and high concentration. Taking the wastewater treatment process system reconstruction of a large vitamin pharmaceutical enterprise in Hubei Province as an example, the optimization of the EGSB and A^(2)O process operation is introduced. The average sludge particle size in the improved EGSB reactor is 2-2.6 mm and the sludge loss rate of the reactor is reduced to about 10%. The final effluent quality of the system could meet the Discharge Standard of Water Pollutants for Pharmaceutical Industry Chemical Synthesis Products Category(GB 21904-2008), and the treatment cost was 4.81 yuan/m^(3).
