摘　　要：为了解静电式空气消毒洁净器动态空气洁净效果，采用尘埃粒子讣数器采样监测，观察其对手术事实际除尘的效果。结果，在启动空气净化器0．5～2．5h内手术室空气中平均中值直径大于0．5μm尘粒数为3811484．1个／m^3，接近世界卫生组织（WHO）的t万级洁净度标准。在手术进程不同时段手术室空气中尘埃颗粒数逐步下降，从净化后0．5～2．5h内平均除尘率达到77．85％。实验组不同粒径范围的颗粒数和总尘粒数低于对照绀。两组手术室内空气中各种粒径范围的颗粒构成情况无差别，以小于5μm尘粒为主，占室内卒气中总尘粒数的96．57％。结论，静电式空气消毒洁净器对手术室内空气中不同粒径粒子具有一定净化效果；净化质量可达到十万级洁净度标准。In order to know the efficacy of electrostatic air - disinfection - cleaning device in dynamic cleaning of air, dust particle counter method was used to observe the efficacy of actual removing of dust in operating room. Results ： During operation of the air - cleaning device for 0.5 ～ 2.5 h. the number of dust particles with median diameter larger than 0.5 μm in air of operating room was 3811484.1 /m^3 , which approximated the WHO standard of 10^5 - grade cleanliness. At various periods in the course of operation, the number of dust particles in air of operating room decreased gradually. Within 0.5 ～ 2.5 h after cleaning, the average rate of removing dust attained 77.85%. The number of dust particles with different diameter ranges and the total number of dust particles in test group were lower than those in control group. The composition of dust particles of various diameters in air of operating rooms of the two groups was not different with the dust particles smaller than 5 μm as the main component, accounting for 96.57% of the total number of dust particles in the indoor air. Conclusion ： The electrostatic air - disinfection - cleaning device has certain efficacy in cleaning dust particles of various diameters in air of operating room and the cleaning quality can attain 10^5 - grade cleanliness standard.
