The phenol disinfectant has low pH value, is easily influenced by alkaline organic substances, pollutes the environment, has pungent smell (irritability to a mucous membrane system of an organism), has smell detention property, has strong toxicity to people and livestock, is generally only used for disinfecting livestock and poultry empty houses, is not suitable for disinfecting during breeding, and has poor sterilizing effect.
Alcohol disinfectants are volatile, have little irritation to skin and mucous membrane, and are commonly used for disinfecting hands, skin and the like. The oxidant disinfectant is mainly used for environmental disinfection, such as disinfection of livestock and poultry houses, feeding troughs, tools, vehicles, floors and walls, has a good sterilization effect especially in a low-temperature environment, is selected as a good disinfectant of a refrigeration house, does not leave residual toxicity on articles after disinfection, but has unstable chemical properties, is ready to use, and has strong oxidizing property, so that skin mucosa and corrosive articles can be stimulated and damaged in high concentration, and the oxidant disinfectant can powerfully damage eyes, respiratory mucosa and environment of human and animals after long-term use.
The surfactant disinfectant has the characteristics of stability, small side effect and the like, but has no effect on non-membrane viruses (such as foot-and-mouth disease viruses and vesicular disease viruses), belongs to a low-efficiency disinfectant, and cannot be used for disinfection when epidemic diseases are epidemic.
Good ventilation must be maintained during intensive cultivation and planting, but air circulation improves the environment and increases the risk of entry of horizontally transmitted viruses. The existing disinfection products have the defects of short disinfection time, single type of killed bacteria and viruses, incapability of durably and effectively killing the bacteria and viruses and difficulty in controlling the biological prevention and control effect of viral pathogenic substances horizontally spread in the air.
