摘要：
针对吡拉西坦原料药生产废水成分复杂、污染物浓度高且难降解的特点，采用气浮—微电解—Fenton氧化—UASB—A/O—生物滤池组合工艺对其进行处理。工程运行结果表明，在进水COD≤10 000 mg/L、NH3-N≤200 mg/L、甲苯≤100 mg/L的条件下，出水COD、NH3-N和甲苯的去除率可达99.6%、97.5%、99.9%。该工艺处理效果稳定，经济效益高，可为其他制药企业废水的处理提供参考。

Abstract:
In view of the complex composition of the production wastewater of piracetam, the high concentration of pollutants and the difficulty of degradation, the combination process of air flotation-microelectrolysis-Fenton oxidation-UASB-A/O-biofilter is carried out. The results of engineering operation show that under the condition of influent COD ≤ 10 000 mg/L, NH3-N ≤ 200 mg/L and toluene ≤ 100 mg/L, the removal rate of COD, NH3-N and toluene of the effluent could reach 99.6%, 97.5%, 99.9%, respectively. The process had stable treatment effect and high economic benefit, and could provide reference for the wastewater treatment of other pharmaceutical enterprises.
