介绍了最近使用臭氧和超声波灭菌微生物的实验方法的结果。本文采用超声空化同时产生臭氧的方法，通过对臭氧浓度、超声发射器功率和水温等因素的研究，优化了水溶液的杀菌过程。利用大气压下的双阻挡层辉光放电和热电制冷模块实现了水溶液中臭氧的高浓度化。这种消毒器由臭氧发生器和250 W的高压脉冲电源组成，臭氧发生器的形状为覆盖有介电材料的扁平电极。灭菌相机配备有在100 W下操作的超声源。在臭氧饱和的蒸馏水中进行了蜡样芽孢杆菌的灭活试验。水溶液中的臭氧浓度为10 mg/l，而臭氧浓度为10 mg/l。
The results of recent experimental methods of sterilization of microorganisms with the use of ozone and ultrasound are presented. The main aim was to optimize the process of sterilization in water solution taking into account the ozone concentration, the power of ultrasonic emitter and the temperature of water.In the present work, the ultrasonic cavitation with simultaneous ozone generation has been used. The high ozone concentration in water solution was achieved by two-barrier glow discharge generated at atmospheric pressure and a cooling thermo-electric module. Such a sterilizer consists of ozone generator in a shape of flat electrodes covered with dielectric material and a high-voltage pulsed power supply of 250 W. The sterilization camera was equipped with ultrasonic source operated at 100 W. The experiments on the inactivation of bacteria of the Bacillus Cereus type were carried out in the distilled water saturated by ozone. The ozone concentration in the aqueous solution was 10 mg/1, whereas the oz...
