Biological air purifier

Abstract

The invention relates to a biological air purifier, and belongs to the technical field of air purification. Methylobacterium sponge balls are obtained in the mode that methylobacterium having specificformaldehyde metabolic pathways and capable of removing pollution benzene series and improved photosynthetic-bacterium inorganic salt culture media are embedded and fixed with sodium alginate and carboxymethyl cellulose, photosynthetic-bacterium sponge columns are obtained in the mode that photosynthetic bacteria having formaldehyde photosynthetic assimilation pathways and inorganic salt culturemedia are embedded and fixed with sodium alginate and carboxymethyl cellulose, and the methylobacterium sponge balls and the methylobacterium sponge columns serve as air purification materials. The sponge balls embedded with the methylobacterium are arranged in a gas purification area, photosynthetic-bacterium sponge strips are soaked in water of a water tank, the photosynthetic-bacterium sponge columns in the water tank can also be replaced with hydroponic plants, the air purifier based on the bioreactor principle is established, polluting formaldehyde and other toxic organic compounds in airare purified, and the aim of purifying indoor air is achieved. The biological air purifier has the advantages of being economical, practical and environmentally friendly, and meets the green and environment-friendly theory requirements in living facilities of modern people.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a biological air purifier. Background technique [0002] Formaldehyde (HCHO) is widely used in chemical synthesis, industrial manufacturing, pharmaceutical synthesis and other industrial fields. Formaldehyde also plays a pivotal role in the synthesis of chemical pesticides and their intermediates. Therefore, formaldehyde pollution is inevitable in the production process of modern chemical pesticides. Air and waste water, many chemical and pharmaceutical workshops, drug product reagent storage warehouses and laboratories of R&D departments have detected formaldehyde pollution. [0003] It is a well-known fact that smoking is harmful to health. There is a high concentration of PM2.5 in the smoke produced by lighting a cigarette, and there are many harmful substances to the human body, which can be roughly divided into six categories: 1) Nitride and olefin subst...

Problems solved by technology

[0005] At present, the purification technologies used by air purifiers to purify and remove formaldehyde and other organic pollutants on the market mainly include physical adsorption technology, nano-photocatalysis technology, plant purification and biodegradation technology, etc. Air purifiers using physical adsorption technology need to be replaced regularly The internal consumables lead to high maintenance costs, and the product filter cannot be recycled and can only be treated as garbage, causing secondary pollution to the environment

Air purifiers using nano-photocatalytic technology are expensive, and have poor purification effects on high-concentration formaldehyde and other organic pollutants. Therefore, the penetration rate of air purifiers using nano-photocatalytic technology in many households is very low.

Air purifiers developed with biodegradable technology are safe and environmentally friendly, and do not need to replace consumables. However, the technology of this type of air purifier is not mature enough, and the proportion of the current market is very small.
