空气过滤系统在猪舍生物安全中的应用研究进展OA

With the increasing intensification and regional concentration of pig farming in my country,aerosol transmission has emerged as a major pathway for the cross-regional spread of serious diseases,including African swine fever(ASF)and porcine reproductive and respiratory syndrome(PRRS),posing significant challenges to traditional biosecurity measures.Air filtration systems,which physically capture dust and droplet nuclei(0.3～5.0 μm)carrying pathogenic microorganisms through multi-stage filtration,can reduce the risk of airborne transmission at its source and are considered a critical engineering technology for establishing high-level biosecurity barriers.This review article summarizes the interception mechanisms,filter media configurations,and ventilation modes of air filtration systems used in pig houses.Their effectiveness in controlling airborne pathogens,improving indoor air quality,and enhancing pig production performance is evaluated.In addition,the limitations and operational challenges associated with their practical application are discussed.The findings provide a reference for the scientific design and standardized application of air filtration systems in large-scale pig farms.
