To explore the feasibility of pulsed ultraviolet (UV) light technology for low-temperature disinfection, a series of experiments were conducted.
Pulsed UV technology's effectiveness in disinfecting Gram-positive and Gram-negative on different carriers were studied under varying temperatures.
Under different temperatures and constant radiation illumination (i.e., distance), the disinfection effect was correlated with irradiation time; among the three carriers, the disinfection effect of cloth sheets was the best, followed by stainless steel sheets, and corrugated paper sheet. The disinfection effect on Gram-negative bacteria was better than that on Gram-positive bacteria overall.
Temperature has a limited effect on pulsed UV disinfection. Irradiation times and carrier types are influencing factors.
为探究脉冲紫外线（UV）光技术用于低温消毒的可行性，进行了一系列实验。
研究了脉冲紫外线技术在不同温度下对不同载体上革兰氏阳性菌和革兰氏阴性菌的消毒效果。
在不同温度和恒定辐射照度（即距离）下，消毒效果与照射时间相关；在三种载体中，布片的消毒效果最佳，其次是不锈钢片，瓦楞纸片最差。总体而言，对革兰氏阴性菌的消毒效果优于革兰氏阳性菌。
温度对脉冲紫外线消毒的影响有限。照射时间和载体类型是影响因素。
