摘　　要：为比较循环风消毒机与紫外线灯对空气的消毒效果，用ＦＡ—１型多级撞击式采样器进行了采样检测。结果， ＭＥ—１型空气消毒器开机 ４０ ｍｉｎ，可使空气中细菌总数消亡率＞９４．８６％。进入后 ６０ ｍｉｎ内，因继续消毒，空气中细菌总数可维持在 ２８～ １８０ ｃｆｕ／ｍ３。紫外线灯照射 ６０ ｍｉｎ．可使空气细菌总数减少≥９０．５４％，但进入后空气细菌总数很快上升。In order to compare the air disinfection efficacy of circulating air disinfection machine and ultraviolet lamp, multigrade impinger--type sampler type FA--1 was used for sampling. The results showed that operation of ME--l--type air disinfector for 40 min could result in total air bacteria decay rate of ≥94.86%. Within 60 min after the room was occupied, continuous disinfection could maintain the total bacterial count of air at 28-180 cfu/ m3. Irradiation of ultraviolet lamp for 60 min could reduce the total bacterial count of air by≥ 90.54%, but the total bacterial count of air increased rapidly after the room was occupied.
