Abstract Gas-phase pulsed corona discharge (PCD) shows promising energy efficiency in oxidation of aqueous pollutants. Further progress requires knowledge in efficiency dependent on the contact surface of treated water sprinkled to the discharge zone. Experimental studies focused on the dependency used phenol and oxalate solutions at various pH for variable oxidation kinetics. For slow reactions within the experimental limits, oxidation rate was growing substantially with the spray density. Rapid oxidation showed an optimum spray density determined by discharge power at sufficiently developed interface. The oxidation kinetics fits to description of a pseudo-second order process predicting optimum choice of sprinkling rate.

作为喷雾密度函数的气相脉冲电晕放电水处理中的氧化能效率

摘要 气相脉冲电晕放电 (PCD) 在氧化水性污染物方面显示出有前景的能源效率。进一步的进步需要有关效率的知识，这取决于喷洒到排放区的处理过的水的接触面。实验研究的重点是在不同 pH 值下使用苯酚和草酸盐溶液对可变氧化动力学的依赖性。对于实验范围内的缓慢反应，氧化速率随着喷雾密度的增加而显着增加。快速氧化显示出由充分发展的界面处的放电功率决定的最佳喷雾密度。氧化动力学符合预测喷洒率最佳选择的伪二级过程的描述。
