通过活存菌数比较,石英管紫外线灯的杀菌作用比高硼管为好;照射距离为1m时比2m时为好;延长照射时间,可增强杀菌效果。
Through the comparison of viable bacteria number, the bactericidal effect of quartz tube UV lamp is better than that of high boron tube; when the irradiation distance is 1m, the bactericidal effect is better than 2m; prolonging the irradiation time can enhance the bactericidal effect.
