Description

technical field [0001] The invention belongs to the technical field of sanitation protection, and more specifically relates to a compound enzyme preparation for disinfecting viruses and its application. Background technique [0002] There are many ways of virus transmission, and the transmission modes that are likely to cause infection include contact transmission, droplet transmission, aerosol transmission, fecal-oral transmission and so on. In order to reduce various transmission risks, it is usually necessary to disinfect viruses in the air environment, medical waste, patients' domestic sewage, excrement and urine, etc. [0003] However, the existing disinfectants are either poor in stability, easy to decompose, or have strong irritant and corrosiveness, or are not suitable for virus killing treatment with complex composition background, or are likely to cause new environmental pollution. more limited. [0004] Therefore, it is urgent to provide a product that can be wi...
