Composite disinfectant and preparation method thereof

Abstract

The invention belongs to the technical field of disinfection, and particularly relates to a composite disinfectant and a preparation method thereof, the composite disinfectant comprises the following components by weight: 50-70 parts of calcium hypochlorite, 2-10 parts of a sodium phosphate compound, 5-10 parts of potassium peroxymonosulfate, 8-15 parts of a nano silver-titanium dioxide compound, and 2-10 parts of an auxiliary agent; the preparation method comprises the following steps: uniformly mixing calcium hypochlorite, a sodium phosphate compound and potassium peroxymonosulfate, adding a nano-silver-titanium dioxide compound, stirring, and adding an auxiliary agent while stirring until all the components are uniformly mixed, thereby obtaining the composite disinfectant. Through synergistic regulation of multiple groups of substances in the composite disinfectant, a large amount of available chlorine can be produced, and the available chlorine is high in stability and high in bactericidal ability.

Problems solved by technology

[0002] Swimming pool disinfection generally adopts chemical agents, ultraviolet rays, ozone or metal ion disinfection methods, among which chemical agent disinfection has the disadvantages of poisonous disinfection reagents to the human body, narrow range of disinfection objects, and difficult to handle after disinfection;

[0003] Ultraviolet disinfection has the disadvantages of maintaining a certain water flow thickness for the disinfected swimming pool and high equipment maintenance costs after disinfection;

[0004] Ozone disinfection has the disadvantages of high power consumption of equipment, excessive use will cause human injury, ozone has poor treatment effect on algae and red nematodes, and needs to be synergistically reacted with chlorine-based agents;

[0005] Metal ion disinfection has the disadvantage of high disinfection cost

[0006] At present, the latest technology adopted in the domestic swimming pool disinfection stage is a disinfectant that combines photocatalytic reactions and silver ions, such as CN201410617021.8, which uses nano-titanium dioxide and silver-loaded activated carbon to form a bactericidal composition. The surface activity and the advantages of "good heat resistance, wide antibacterial spectrum, and validity period" of silver-loaded activated carbon can realize the harmless sterilization and disinfection of swimming pools. In the filter, the flow rate and time required for the treatment of swimming pool wastewater are determined by the size of the filter, and the treatment of swimming pool wastewater takes a long time
