Abstract

The invention relates to the technical field of indoor air purification, and particularly discloses a method for efficiently degrading indoor formaldehyde. The method comprises the steps of S1, activating methyl bacillus, pseudomonas and rhodopseudomonas palustris for later use; S2, inoculating activated methylobacterium and activated pseudomonas into a liquid culture medium A, culturing for 12-18hours, inoculating activated rhodopseudomonas palustris into the liquid culture medium A, and culturing in a dark environment with formaldehyde; S3, co-culturing the microorganisms and green plants,and adding an amino acid solution into a culture solution to obtain potted plants capable of degrading indoor formaldehyde; and S4, adding the amino acid solution into the potted plants every other 2-20 days. The method disclosed by the invention has the advantage of efficiently degrading indoor low-concentration formaldehyde.

Description

technical field [0001] The application relates to the technical field of indoor air purification, more specifically, it relates to a method for efficiently degrading indoor formaldehyde. Background technique [0002] Formaldehyde is a common extremely volatile organic compound (Volatile Organic Compounds, VOCs). As a basic chemical raw material, it is widely used in the fields of resin, leather, paint, coating and plastic. With the development of furniture manufacturing, interior building materials and other industries, adhesives and coatings made of organic raw materials containing formaldehyde will be used in furniture and decoration materials, and the formaldehyde will be continuously released into the indoor environment, causing indoor pollution. Formaldehyde content is too high. In addition, formaldehyde in furniture and interior decoration materials will continue to be released into the indoor environment for a long period of time (up to 3-15 years), causing the forma...
