摘要：

采用氧化-生化法处理制药工业废水,处理量为100m³/d,进水COD_Cr为1000～4000mg/L。运行实践表明,氧化处理工艺能够降解该废水中的大多数高分子化合物;生化处理中的水解酸化工艺可明显提高废水的可生物降解性,生物接触氧化处理工艺COD_Cr去除率大于97%。采用该工艺的废水处理装置从2003年9月运行至今,处理出水各项指标完全符合国家排放标准,运行结果表明,该工艺处理效果稳定,耐负荷冲击性强,工艺组合合理,具有广阔的工业应用前景。

Abstract:

Wastewater from pharmaceutical industry is treated by oxidation - biotreatment process:treating quantity is 100 m³/d, inflow COD_Cr value is 1 000 ～ 4 000 mg/L. Most macromolecular compounds can be degraded by oxidation process. Biotreatment process include hydrolysis acidification and biological contact oxidation process. Hydrolysis acidification process is an effective pretreatment one of organic wastewater, especially for highly conc-entrated and refractory wastewater. It can improve the biodegradability. COD_Cr removal rate of biological contact oxidation process is over 97%. From its running in september, 2003 till now, all the quality indexes of treated water agree with the national discharge standard. The running results show that the treatment efficiency of the technology is stable, shock load resistance range is wide and the combination of processes is reasonable. Its future of industrial application is promising.

Key words: pharmaceutical wastewater, oxidation treatment, biotreatment
