Problems solved by technology

Although the device can remove some particulate pollutants, it has a limited effect on the removal of organic pollutants, especially volatile organic compounds.
[0010] It can be seen from the above that the current air purifiers are mainly divided into two categories. One is the air purifier that filters the nature of inhalable particulate matter. It is removed by filters made of various adsorbent materials, but it cannot completely remove the air. Pollutants in the filter, and the adsorption, pollution and saturation of the filter material make the treatment effect unstable; in addition, for the user, the cleaning and replacement of the material is more difficult
The other is to increase the physical and chemical effects of water, oxidants, photocatalysts, etc. on the basis of filtration. These methods have low removal efficiency for organic pollutants, and the applicability is not wide, and photocatalysts have greatly increased the manufacturing cost and replacement. Cost, oxidants such as ozone leakage have caused safety hazards to the body, while the survival period of plants is not long, maintenance is difficult, and the effect of water is not good enough, etc.

Abstract

The invention relates to an indoor air treatment device and method. The method comprises the following steps of carrying out microorganism treatment on the indoor air, adsorbing by activated carbon, and disinfecting by ultraviolet rays, wherein the microorganism treatment adopts an immobilized microorganism treatment technique. The device comprises an immobilized microorganism filter tank, an activated carbon adsorbing assembly and a space ultraviolet radiating assembly, wherein the immobilized microorganism filter tank adopts the microorganism immobilizing technique. The method and the device have the advantages that an adopted microorganism immobilizing carrier has strong microorganism immobilizing ability, the biological loading amount is large, and the immobilized microorganism can simultaneously present the aerobiotic, facultative anaerobic and anaerobic bacteria coexistence state; the particulate pollutants, organic matters, ammonia and nitrogen, nitrate nitrogen and sulfide pollutants in the waste gas can be simultaneously removed, the treatment speed is high, the purifying efficiency is high, and the cost is low.

Description

technical field [0001] The present invention relates to a device and method for treating indoor air. More specifically, the present invention relates to a device and method for treating polluted gas, that is, a combination of physical and chemical treatment and biological treatment is used to treat indoor air. Apparatus for treatment and method thereof. Background technique [0002] At present, due to the aggravation of air pollution, the dust, PM2.5 and volatile organic compounds in the air are seriously exceeding the standard, and the toxic and harmful gases such as formaldehyde released from furniture and interior wall coatings, the indoor air is already in an unsafe state. Therefore, a kind of indoor air is developed. Purifiers to remove air pollution and protect the health of the people have become an urgent national demand. [0003] An office indoor air purification device described in CN105944558A is made of titanium tubes with honeycomb titanium dioxide nanostructur...
