研究了臭氧氧化处理含两种人用抗生素和一种兽用抗生素的三种不同合成制药废水，以提高其可生化性。考察了pH值、初始化学需氧量（COD）值以及过氧化氢投加量对臭氧氧化过程的影响。以总有机碳（TOC）、COD、生化需氧量（BOD）和芳香族化合物含量（UV 254）为指标，评价臭氧氧化工艺的性能。通过对所选含不同抗生素废水的生物降解性进行比较，证实了生物降解性的变化与目标化合物有关。当臭氧投加量为2.96 g/l时，兽用抗生素制剂废水的BOD_5/COD比值从0.077增加到0.38，人用抗生素I和人用抗生素II的BOD_5/COD比值分别从0增加到0.1和0.27。此外，本次调查的结果表明，臭氧化过程是能够实现高水平的COD和芳香性去除在其自然pH值。(C)2002爱思唯尔科技有限公司版权所有。
Ozonation of three different synthetic pharmaceutical formulation wastewater containing two human antibiotics and a veterinary antibiotic has been studied to enhance the their biodegradability. The effects of pH and initial chemical oxygen demand (COD) value as well as addition of hydrogen peroxide on ozonation process were investigated. Total organic carbon (TOC), COD, biochemical oxygen demand (BOD), and aromatic content (UV254) were the parameters followed to evaluate the performance of ozonation process. Comparison of the biodegradability of selected wastewaters containing different antibiotics confirmed that the variation of biodegradability was associated with the target compound. While BOD5/COD ratio of veterinary antibiotic formulation wastewater was increased from 0.077 to 0.38 with an applied ozone dosage of 2.96 g/l, this ratio for human antibiotic I and human antibiotic II was increased from 0 to 0.1 and 0.27 respectively. Moreover the results of this investigation showed that the ozonation process is capable of achieving high levels of COD and aromaticity removals at about their natural pH values.
