Analysis and research of several indoor air purification methods
Abstract
Air pollutants refer to foreign substances that enter the near ground or the near ground environment in the form of gas. Generally, they are substances that are discharged into the atmospheric environment during human activities or natural processes and have harmful effects on human beings or the environment. Usually there are solid pollutants and gaseous pollutants two categories, solid pollutants in the common dust, suspended particles, etc. (usually called particulate matter); Among the common gaseous pollutants are volatile organic compounds, nitrogen oxides, benzene, sulfur oxides, ammonia, hydrocarbons, formaldehyde and so on caused by pollution caused by decoration materials. Aiming at different air pollutants, this paper introduces the differences and characteristics of several air purification methods, and points out the research significance of air purification technology.
