Abstract

The invention discloses an air purifying material of microorganism absorption degradation, a preparation method and applications thereof. The air purifying material of microorganism absorption degradation is obtained by embedding biological grains with 2 to 4mm grain diameter of pseudomonades or acinetobacter which are cultured and acclimatized in a crosswise way in calcium alginate gel. The air purifying material of microorganism absorption degradation can be used in the long time purification of formaldehyde and benzene series pollution in rooms with obvious effect. The product has the advantages of high activity of immobilized cells, good stability, effectively reducing the content of chemical pollution of formaldehyde and benzene series pollution in rooms, being beneficial for realizing the recycling, regenerating and reusing of biocatalysts, and seriously avoiding the pollution to room environment by microorganisms. The raw material has low cost, the preparation process is simple, easy and convenient in operation, and product can be applied in different reactors.

Description

technical field

[0001] The invention belongs to the field of air purification, and relates to an air purification material for microbial adsorption and degradation, a preparation method and an application. Background technique

[0002] With the advancement of science and technology, people have higher and higher requirements for indoor air quality. As an important part of indoor air quality, chemical pollutants have attracted more and more attention. With people's pursuit of interior decoration, a large number of decorative materials have entered the indoor environment. Adhesives in decorative materials, synthetic wood boards, and paints and coatings will release a large amount of volatile organic compounds. Among them, formaldehyde and benzene series are the most common and most harmful pollutants in air pollution caused by interior decoration, and they are also the most urgent chemical pollutants that need to be removed.

[0003] Formaldehyde (HCHO), also known as "formal...
