摘　　要：目的:观察基于高压脉冲电场杀菌技术的新型空气消毒净化设备对室内空气的消毒效果。方法:在实验室模拟和现场两种情况下对设备的空气消毒效果进行相关试验。结果:在实验室模拟试验条件下,基于高压脉冲电场杀菌技术的新型空气消毒净化设备对人工模拟产生的粘质沙雷氏菌、白色葡萄球菌和白色念珠菌气溶胶的平均杀灭率分别为98.62%、98.65%和97.93%;在口岸现场试验条件下,设备对自然菌气溶胶的平均杀灭率为90.58%。结论:基于高压脉冲电场杀菌技术的新型空气消毒净化设备在规定的使用条件下,对空气微生物气溶胶具有良好的杀灭效果,是一种值得推广新型空气消毒净化设备。Objective： To investigate the indoor air disinfection effects of a new type of air disinfection and puri- fication equipment based on high- voltage pulsed electric field sterilization technology. Methods： Experiments on the disinfection effects were carried out under the laboratory simulation and field test. Results： The new high - volt- age pulsed electric field sterilization technology- based air sterilization purification equipment produced an average killing rate of 98.62%, 98.65% and 97.93%, respectively for artificial simulated aerosol of Serratia marcescens, Staphylococcus albus and Candida albicans in the laboratory simulation test, and 90.58% for the natural bacteria aerosols in the port field test. Conclusion： Under specified using conditions, the new high - voltage pulsed electric field sterilization technology - based air sterilization purification equipment had a great killing effect on air microbial aerosols, and was worthy to promote as a new type of air disinfection and purification equipment.
