采用臭氧微纳米气泡(O3-MNBs)技术处理水中磺胺嘧啶(SD)污染物，对比分析了臭氧气源与空气气源在微纳米气泡体系中的气泡特性及其对SD降解效率的影响。结果表明，臭氧微纳米气泡浓度显著高于空气微纳米气泡，且其粒径略小，臭氧微纳米气泡体系对SD的降解效率显著高于空气微纳米气泡体系。考察了O3-MNBs体系中SD初始浓度、pH值、臭氧浓度、H_2O2浓度及无机阴离子等因素对SD降解效率的影响。实验表明，SD初始浓度为50 mg/L、pH为10、臭氧浓度为35 mg/L的条件下，添加1 mmol/L H_2O2,反应80 min后SD去除率达100%;无机阴离子中NO~-3的抑制作用较显著，Cl~-、CO32-和SO42-对SD降解影响相对较小。研究为臭氧微纳米气泡技术处理抗生素废水提供了参考。
Abstract：The study employed ozone micro-nano bubbles(O3-MNBs) technology to treat sulfadiazine(SD) contaminants in water, comparing and analyzing the bubble characteristics of ozone and air gas sources in the micro-nano bubble system and their effects on SD degradation efficiency.The results showed that the concentration of ozone micro-nano bubbles was significantly higher than that of air micro-nano bubbles, with a slightly smaller bubble size.The degradation efficiency of SD in the ozone micro-nano bubble system was significantly higher than that in the air micro-nano bubble system.Factors such as the initial concentration of SD,pH value, ozone concentration, H_2O2 concentration, and inorganic anions in the O3-MNBs system were examined for their effects on SD degradation efficiency.Experiments demonstrated that under the conditions of an initial SD concentration of 50 mg/L,pH of 10,and ozone concentration of 35 mg/L,adding 1 mmol/L H_2O2 achieved a 100% SD removal rate after 80 min of reaction.Among the inorganic anions, NO~-3 had a more pronounced inhibitory effect, while Cl~-,CO32-,and SO42- had relatively smaller impacts on SD degradation.This study provides a reference for the application of ozone micro-nano bubble technology in treating antibiotic wastewater.
