Abstract：The aim of this experiment was to study the disinfection effect of sanitizer on Newcastle disease virus(NDV)Lasota strain and infectious bronchitis virus(IBV)HV80 strain in the air,and the deodorization effect in the chicken house.The two viruses were formed into aerosols in the test chamber,and the virus titer in the test chamber at different time points after disinfection with the sterilizer was determined,and the virus elimination rate was calculated after comparison with the control group.A deodorization test was carried out in a laying hen house with 2 000 eggs,and five odor collection points were set up.A portable detector of ammonia and hydrogen sulfide was used to detect the concentration of ammonia and hydrogen sulfide in the hen house and calculate the odor degradation rate at five time points before and after the sterilizer was used.The results showed that the sterilization rate of NDV Lasota strain was 99.99％after 40 min operation,and the sterilization rate of IBV HV80 strain was 99.87％after 20 min operation.After 60 min operation,the degradation rate of ammonia and hydrogen sulfide in the chicken house reached more than 90％.The research shows that the sterilizer not only has a good ability to kill the virus,but also has a good auxiliary effect on the improvement of the environment of the chicken house.
