Description

DESCRIPTION 7501578 Natural Plant Deodorant, Preparation Method and Application Thereof

TECHNICAL FIELD The invention belongs to the technical field of environmental sanitation air purification, and specifically relates to a novel plant deodorant and a preparation method thereof.

BACKGROUND With the increase of population and the rapid development of society, all kinds of domestic garbage, industrial garbage, domestic sewage, industrial sewage and breeding manure are also increasing rapidly. However, these wastes often have a high proportion of organic components, complex compositions and pathogenic pathogenic microorganisms, parasites, etc, and organic substances piled up for a long time will also produce volatile malodorous gases, including hydrogen sulfide, ammonia, indole, mercaptan, thioether, amines, amides, aldehydes and volatile fatty acids, etc, through complex reduction reactions under anaerobic conditions. These smells will not only reduce the quality of human living environment, but also lead to the aggregation of mosquitoes and flies. Mosquitoes and flies not only pollute the environment, but also spread germs and diseases, which do great harm to the lives of nearby residents. Therefore, it is urgent to solve the problem of environmental stench.

At present, the methods of deodorization mainly include fragrance masking, chemical reaction, physical action, biological action and so on. Scent masking method can cover the malodor by spraying flavors frequently, but it can't reduce the components of malodor. Moreover, there are many kinds of organic components added in these flavors, which may be harmful to human body. Chemical reaction method refers to the reaction of addition, redox, neutralization and condensation with volatile odor molecules, which changes the structure of odor molecules and turns them into non-toxic and odorless substances, thus achieving deodorization effect. Physical action method refers to the adsorption and fixation of odor molecules by using its own micro-structure, which dissolves or fixes odor molecules and causes odor to disappear. And biological action method is to use effective components to inhibit the growth of microorganisms and reduce the activity of microorganisms to 7901578 decompose organic matter, thus reducing the generation and emission of odor.
