微酸性电解水雾滴沉积量及粒径对畜牧环境杀菌效果的影响

微酸性电解水为畜牧业初步应用的环保消毒剂,为精确喷雾以减少残留,先利用称重法测量它在不同孔径及压力下的雾滴沉积量,研究该沉积量对杀菌效果影响,确定对衣物表面消毒最佳单位沉积量。随后对比不同雾滴粒径对衣物表面细菌的杀灭效果,以确定喷雾消毒方式。结果表明,不同压强及喷头下,雾滴沉积量具显著性差异（P〈0.05）。且呈中间密集、两端稀疏特征;随压强及孔径增大,两端呈先升后降趋势。微酸性电解水（pH值6.15~6.35,有效氯浓度135 mg/L）对衣物表面消毒最佳沉积量为1.49×10~（-2）g/cm~2。大雾滴（80~90μm）杀菌率在同时间下显著高于小雾滴（P〈0.05）,但其空间分布均匀性显...

Summary:微酸性电解水为畜牧业初步应用的环保消毒剂,为精确喷雾以减少残留,先利用称重法测量它在不同孔径及压力下的雾滴沉积量,研究该沉积量对杀菌效果影响,确定对衣物表面消毒最佳单位沉积量。随后对比不同雾滴粒径对衣物表面细菌的杀灭效果,以确定喷雾消毒方式。结果表明,不同压强及喷头下,雾滴沉积量具显著性差异（P〈0.05）。且呈中间密集、两端稀疏特征;随压强及孔径增大,两端呈先升后降趋势。微酸性电解水（pH值6.15~6.35,有效氯浓度135 mg/L）对衣物表面消毒最佳沉积量为1.49×10~（-2）g/cm~2。大雾滴（80~90μm）杀菌率在同时间下显著高于小雾滴（P〈0.05）,但其空间分布均匀性显著（P〈0.05）低于小雾滴（≤30μm）。雾滴粒径及沉积量对微酸性电解水杀菌效果具显著影响（P〈0.05）。

As the increasing demand for efficient and sustainable production and the global demand for reduced antimicrobial drug consumption in livestock production, the importance of disinfection has increased significantly. However, potentially toxic, corrosive problems have arisen because of the use of chemicals as disinfecting agents. Slightly acidic electrolyzed water （SAEW） which has recently been developed in livestock production is a new environmental friendly disinfectant. In order to make the precision spraying of this disinfectant and increase the disinfectant usage efficiency for reducing residual and disease risk, in this study, the influence of droplets size
