摘　　要：通过现场实验研究了6-APA制药厂生化处理出水的臭氧氧化特性及其动力学规律。结果表明，当臭氧浓度为27．5mg／L，气水接触时间为80min时，COD、UV254、NH3-N和色度的去除率分别可达72．95％、73．28％、72％和96．25％，达到《发酵类制药废水工业水污染物排放标准》（GB21903—2008）排放控制要求。拟合结果表明，在0～10、10～30和30～90min时段内，臭氧氧化过程遵循拟一级反应，但反应速率逐渐降低。当气水接触时间为30min时，废水可生化性可由0．1提高至0．35，采用臭氧／生物处理的联合工艺也有望使出水达到相同的排放控制要求。The ozonation characteristics and kinetics of bio-treated effluent from 6-APA pharmaceutical fac- tory were studied through field test. The results indicate that the removal rates of COD, UV254 , NH3-N, and eol- ority can reach 72.95% , 73.28% , 72% , and 96.25% , respectively when the ozone concentration is 27.5 mg/ L, and the contact time between ozone and wastewater is 80 rain, satisfying the emission control requirements of Discharge Standards of Water Pollutants for Pharmaceutical Industry of Fermentation （GB 21903-2008 ）. The fitting results show that the ozonation reaction conforms to pseudo-first order reaction kinetics within the time intervals of 0 to 10 rain, 10 to 30 rain and 30 to 90 rain, while the reaction rate decreases gradually. When the contact time is 30 min, the biodegradability of wastewater increases from 0. 1 to 0.35. The wastewater is expected to meet the same emission control requirements when combined O3/biotreatment technology is taken.
