Abstract

The invention discloses sewage disinfection powder as well as a preparation method and a use method thereof, which belong to the technical field of water disinfection treatment. According to the invention, potassium peroxymonosulfate composite salt and sodium dichloroisocyanurate are used as sterilization components of the disinfection powder, and are combined with stable and synergistic components such as boric anhydride, sodium chloride and the like, so that the problems of high safety risk, high disinfection cost and the like of the conventional sewage disinfectant and disinfection method are solved.

Description

technical field [0001] The invention relates to the technical field of water disinfection treatment, in particular to a sewage disinfection powder and its preparation method and use method. Background technique [0002] Hospital sewage and urban sewage contain a large number of pathogenic microorganisms, which need to be disinfected before they can be discharged into urban sewage pipe networks or natural water bodies. [0003] At present, the sewage disinfection methods mainly include sodium hypochlorite method, liquid chlorine method, chlorine dioxide method and ozone method. [0004] Among them, the sodium hypochlorite method: due to its low price and easy use, this method is widely used. However, sodium hypochlorite has weak disinfection ability and poor stability; especially in summer, the active ingredient is lost quickly and it is prone to explosion accidents. [0005] Liquid chlorine method: Because of its strong disinfection ability and low price, it is widely used...
