摘　　要：研究旨在评估空气净化器和换气对冬季哺乳母猪舍空气环境的影响。试验选取三栋封闭式哺乳母猪舍,安装等离子体净化装置作为净化舍,拉窗留2cm缝隙为换气舍,一栋无处理为对照舍。每天9:00、13:00和17:00分别检测猪舍内可吸入颗粒物、有害气体、细菌等指标。结果表明:与对照舍相比,净化舍内PM2.5、PM10浓度、CO2、NH3等有害气体浓度均显著降低(P<0.05),且能显著降低舍内病原微生物的数量(P<0.05);换气舍内空气卫生质量相对优于对照舍和净化舍,但与净化舍相比,其舍内温度略低。结论:冬季在猪舍安装净化装置和在白天适当缝隙换气,都能有效地改善冬季有窗封闭哺乳猪舍的空气卫生质量。This study was conducted to evaluate the influence of air purifiers and ventilation on air quality of lactating sows house in winter.Three enclosed lactating sow houses with windows were selected for this experiment.The first house equipped with the purifying installation was designated as the purification house,the second house which the window opened 2 cm for ventilation was designated as the ventilation house,and the last untreated house was designated as the control house.The solid particles,harmful gases and microorganisms concentration of sow house were determinated at 9:00,13:00 and 17:00 every day,respectively.The results indicated that the solid particles concentration including PM 2.5 and PM 10 and harmful gas content,such as CO 2 and NH 3 in purification house were significantly decreased(P<0.05)compared to the control house.In addition,the number of pathogenic microorganisms was also significantly reduced by purification treatment(P<0.05).The air quality in ventilation house was better than the other two houses,whereas its indoor temperature was slightly lower than purification house.In conclusion,both installing purification device in sow house and ventilation treatment by opening the window appropriately at midday in winter could effectively improve the air quality of enclosed lactating sows house.
