摘要： 为系统对比平层与楼房两种典型猪场模式的粉尘传播特性差异，揭示建筑结构对粉尘传播的影响机制，本研究采用荧光粉示踪模拟试验方法，以某公司同一区域的平层猪场和楼房猪场为研究对象，在浴室关口、物资传递窗、出猪台、病死猪处理平台等4个关键位点进行为期7 d的实地观测，记录荧光粉传播距离、扩散范围及分布特征。结果表明：平层猪场粉尘传播范围广泛，最远传播距离为出猪台，可达55 m，传播机制以风力驱动为主；楼房猪场传播范围相对较小，最远传播距离也为出猪台，可达10 m，但存在严重的楼层间交叉污染，电梯和人员活动是主要传播因素。综上所述，两种猪场建筑结构差异导致粉尘传播特性显著不同，应根据各自特点采取针对性防控策略。

Abstract: To systematically compare the dust transmission characteristics between flat and multi-story pig farm models and elucidate the mechanisms by which architectural structures influence dust dispersion, this study employed a fluorescent powder tracing simulation method. Field observations were conducted over seven days at four critical locations-including bathhouse entrances, material transfer windows, pig exit platforms, and dead pig handling areas in both flat and multi-story pig farms within the same facility. Data on fluorescence powder travel distance, diffusion range, and distribution patterns were recorded. Results demonstrated that flat pig farms exhibited extensive dust dissemination with the farthest transmission distance reaching 55 m at the exit platform, primarily driven by wind forces; whereas multi-story farms showed relatively limited transmission ranges (up to 10 m at exit platforms), but experienced significant cross-contamination between floors, with elevators and personnel movement being major transmission factors. In conclusion, structural differences between these two farm types lead to markedly distinct dust transmission behaviors, necessitating tailored prevention strategies based on their specific characteristics.
