Tetracycline (C₂₂H₂₄N₂O₈) is a well-known emerging contaminant that is generally used in pharmaceuticals and personal-care products. Traditional biological treatment technologies are inadequate for quickly and completely removing tetracycline from wastewater; hence, the ozonation investigated in this study is preferable. The effects of several reaction parameters, such as tetracycline concentration, pH, temperature, addition of ·OH radical scavengers, gas type, and bubble size, were investigated. Experimental results indicated that the connection of air or pure oxygen gas with a millibubble or ultrafine-bubble compressor could not remove tetracycline. As the ozonation was carried out, the degradation of tetracycline exceeded 99.5 %, followed by approximately 40 % mineralization with 60-min treatment. A lower pH level or a higher reaction temperature was practical to increase the degradation of tetracycline; also, the increase in the formation of ·OH radicals was impressive to mineralize further the organic compound. According to the experimental results shown in this study, ultrafine-bubble ozonation is a feasible way to degrade the antibiotics effectively and decrease the toxicity in water within a short treatment duration, and with low ozone gas consumption.

四环素（C ₂₂ H ₂₄ N ₂ O ₈）是一种众所周知的新兴污染物，通常用于药品和个人护理产品中。传统的生物处理技术不足以快速，彻底地去除废水中的四环素。因此，在这项研究中研究的臭氧化是优选的。研究了几种反应参数的影响，例如四环素浓度，pH，温度，添加的-OH自由基清除剂，气体类型和气泡大小。实验结果表明，空气或纯氧气与毫气泡或超细气泡压缩机的连接不能除去四环素。当进行臭氧化时，四环素的降解超过99.5％，随后用60分钟处理后约40％的矿化。较低的pH水平或较高的反应温度对于增加四环素的降解是可行的。另外，·OH自由基形成的增加令人印象深刻，以进一步使有机化合物矿化。根据这项研究中显示的实验结果，超细气泡臭氧化是一种有效的方法，可以在短时间内有效地降解抗生素并降低水中的毒性，并且臭氧消耗量低。
