Background
Indoor decoration pollution refers to the phenomenon that oxygen, formaldehyde, benzene, ammonia, volatile organic compounds and other gases harmful to human health are mixed in indoor air. It is well known that the decoration of indoor space environment can bring about various environmental problems, such as: the use of building materials containing toxic and harmful substances can affect the indoor air quality; various dusts, wastes and noise pollution are generated in the decoration process, and the dust, the wastes and the noise pollution can seriously affect the life of people. The sources of interior decoration pollution are many, and a considerable part of the pollution is caused by improper materials used in the decoration process, including volatile organic gases such as formaldehyde, benzene, xylene and the like. However, if harmful gases volatilized from the decoration materials are not removed in time, certain harm can be caused to the health of people living in the decoration materials.
A plurality of treatment products aiming at formaldehyde or benzene series appear on the market, such as photocatalyst formaldehyde removal and the like. However, such aldehyde removal products need to be performed under the illumination condition, and the indoor pollution gases are various, and the aldehyde removal products with single function cannot effectively improve the indoor air environment.
