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)-A2O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/m3。
Abstract:
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 A2O 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/m3.
