　　Physical technology

　　Photocatalyst is a general term for photo-semiconductor materials with photocatalytic function represented by nano-sized titanium dioxide. It is coated on the surface of the substrate and produces catalytic degradation function under the action of light, which can degrade toxic and harmful gases in the air. The photocatalytic air purification device with ultraviolet light source has a purification efficiency of 3% (calculated based on the difference in the concentration of pollutants at the inlet and outlet of the device), and the best is less than 5%. Therefore, its purification efficiency is very low, and related studies have shown that highly toxic intermediate products are produced in the photocatalytic process.

　　Negative ion and plasma method

　　It is by charging the particles in the air to coalesce to form larger particles and settle, but the particles are not actually removed, but attached to the nearby surface, which is easy to cause dust again. High-pressure ion technology will produce by-products such as ozone during the work process.

　　Biotechnology

　　Sesquiterpenoids are often found in volatile oils in the form of alcohols, ketones, lactones, etc. in plants. They have strong aroma and biological activity. They can effectively decompose particles and bacteria in the air, and have sterilization, Remove peculiar smell, increase the oxygen content of the air, keep the air fresh and so on. This plant has a certain odor left in the air, and the odor will quickly disappear once the oxidation process is completed. Unlike other plant essential oils, it stays for a long time. The active ingredient terpenoid small molecules simultaneously surround, oxidize, decompose, remove or harmlessize harmful pollutants such as aldehydes, benzene, and ethers, and increase the effective oxygen content in the air, which significantly improves the function of the human respiratory system. Developed countries in Asia, Singapore, Japan, Hong Kong, and Taiwan have taken the lead in using this technology to purify the air in cities, homes, and cars. With the increasingly frequent exchanges between Hong Kong, Macao and Taiwan, this technology has also entered mainland China.

　　Polymerization Technology

　　ncco oxygen polymerization is a technology that specializes in treating and decomposing gaseous pollutants in the air, and cannot be used to treat solid pollutants.

　　Nano materials can be adjusted according to the characteristics of pollutants to improve the system's ability to treat specific pollutants.

　　After nanomaterials adsorb pollutants, they can use active oxygen to decompose pollutants and continuously regenerate. This will not only greatly extend the life of the system, but also increase the capacity for treating pollutants.

　　The pollutant decomposition process of active oxygen in nanomaterials is much faster than in the air. In addition, a catalyst is added to the nanomaterials to further increase the rate at which pollutants are decomposed by active oxygen.

　　It cannot deal with non-gaseous pollutants that are difficult to decompose, such as oil and dust. The nanopores in nanomaterials will be blocked by these substances and lose the ability to deal with pollutants.

　　Mineralization decomposition

　　This technology adopts the method of mineralization and decomposition to make micro-nano structural materials, improve its adsorption capacity, increase the response ability to light, break through the activation energy from ultraviolet light to visible light, promote carrier separation, reduce the probability of recombination, and degrade The efficiency of pollutants has increased by two orders of magnitude, and the mineralization rate has increased by 85%.

　　The treatment rate of mineralized formaldehyde reached 87% through the authoritative inspection by the National Indoor Environment and Indoor Environmental Product Quality Supervision and Inspection Center. This technology successfully realized the loading of photocatalytic materials, and maintained the high activity of nano powders, and quickly mineralized organic pollutants in wastewater and exhaust gas into CO2 and H2O.
