空气智能净化系统对密闭猪舍空气质量的影响

The effect of air intelligent purification system on the air quality in enclosed pig house

为研究空气智能净化系统对密闭猪舍空气质量的影响,本试验将50日龄仔猪分为2组,分别饲养在条件一致的密闭猪舍中。一栋作为对照组(未安装空气智能净化系统),另一栋猪舍作为试验组(安装空气智能净化系统)。结果表明:空气智能净化系统开启后,猪舍中有害气体(NH_3、CO_2)、总悬浮颗粒物(TSP)以及需氧型微生物气溶胶浓度均呈下降趋势。此外,同对照组相比,试验组NH_3、CO_2、TSP以及需氧型微生物气溶胶浓度的最大降幅分别为35.98%、29.15%、67.97%和72.59%(P<0.01)。说明空气智能净化系统可以显著改善密闭猪舍的空气质量。

The present study was designed to evaluate the effect of air intelligent purification system on the air quality in enclosed pig house. Fifty - day - old piglets were randomly divided into two groups. All of these piglets were raised in the same conditions. Group 1 was the control group without using air intelligent purification system while Group 2 was the treatment group using the system. The results showed that the con- centrations of these parameters including harmful gas（ NH3 , CO2 ） , total suspended particulates（TSP） and aerobic microbial aerosols reduced recluced after using air intelligent purification system in enclosed pig house. The percentages of NH3 , CO2 ,TSP and aerobic microbial aerosols in the treatment group were reduced up to 35.98% ,29.15% ,67.97% and 72.59% （ P 〈 0.01 ） respectively compared with those values in the control group. In conclusion,this study revealed that air intelligent purification system can improve the air quality in enclosed pig house.
