Abstract

The kinetics of degradation of pharmaceutical drugs is studied by ozonation in a fine bubble system. In the present experimental work, fine bubbles of ozone were used for degradation of pharmaceutical drugs soluble in water. The ozonation of pharmaceutical drugs by ozone bubbles was found to be very effective at high pH and high ozone flow rates. The apparent reaction rate constant was estimated at different pH of the solution. The axial variation of ozone concentration in solution in the reactor is analyzed by dispersion model. The volumetric mass transfer coefficients based on the ozonation of pharmaceutical drugs by fine bubble based are also enunciated in this present work. The results may be useful for removal of drug waste in water treatment process by advanced oxidation techniques.

植物原型中被臭氧细小气泡降解的药物的臭氧化动力学和传质动力学

摘要

通过在细气泡系统中进行臭氧化研究了药物降解的动力学。在本实验工作中，臭氧的细小气泡被用于降解溶于水的药物。发现在高pH和高臭氧流速下，臭氧气泡对药物的臭氧作用非常有效。在溶液的不同pH下估计表观反应速率常数。用分散模型分析了反应器中溶液中臭氧浓度的轴向变化。在这项目前的工作中也阐明了基于药物通过细小气泡臭氧化的体积传质系数。该结果对于通过高级氧化技术去除水处理过程中的药物废物可能有用。
