【摘要】：為探究冬季智能化密閉商品肉雞舍生物氣溶膠分布規(guī)律,在山西中部某雞舍均勻地設置了36個采樣點,使用Anderson-6撞式空氣微生物采樣器,對白天(AM10∶00-PM3∶00)和夜間(PM10∶00-AM3∶00)兩個時段的細菌和大腸桿菌的氣溶膠粒徑分布進行分析,并對細菌、大腸桿菌、金黃色葡萄球菌、霉菌等的氣溶膠濃度分布以及氣體和粉塵等的濃度進行監(jiān)測。結果表明:細菌氣溶膠主要存在于6級空氣微生物采樣器的Ⅰ、Ⅱ、Ⅲ級;主要刺激人體的上呼吸道;通風模式的不同對粉塵濃度的分布影響較大,對微生物氣溶膠濃度分布影響不大;白天微生物氣溶膠濃度分布與粉塵濃度分布不相關,夜間相關。
[Abstract]:In order to investigate the distribution of biological aerosol in an intelligent closed commercial broiler house in winter, 36 sampling points were set up in a chicken house in the middle of Shanxi Province, and Anderson-6 air microorganism sampler was used. The aerosol particle size distribution of bacteria and Escherichia coli in two periods of AM10:00-PM3:00 and PM10:00-AM3:00 were analyzed, and bacteria, Escherichia coli, Staphylococcus aureus were analyzed. The aerosol concentration distribution of mold and the concentration of gas and dust were monitored. The results showed that bacterial aerosol mainly existed in grade 鈪，
