Abstract
Objective To observe the disinfection effect of compound sodium hypochlorite disinfectant to the air in the tunnel.Method Microbial air sampler to sample and culture were used to evaluate the disinfection effect of the disinfection aerosol.Results Using compound sodium hypochlorite disinfection containing 1 000 mg/L available chlorine with 10 ml/m3 of disinfectant for aerosol spraying disinfection,operation for 30 min in the tunnel,the eliminated rate of natural bacteria was 99.7%,the eliminated rate of fungi was 99.1%.Conclusion Using compound sodium hypochlorite disinfection containing 1 000 mg/L available chlorine with 10 ml/m3 spraying has good disinfection effect to the air in the tunnel.
