Background
Indoor environments are the main place where people live, work, and socialize, and most of the life time of people is spent in indoor environments. The human beings can not survive in the air, and the fresh air is breathed to be beneficial to the health of the human bodies. However, typically 50% -60% of the room air is recycled, up to 90% of the air being recycled in the conditioned room. Indoor decoration materials, furniture coatings and harmful substances released by partial household appliances and particulate matters in air cause increasingly serious pollution to indoor air, and according to related research reports that the harmful substances polluting the indoor air are more than hundreds of types, wherein the harmful substances having the greatest influence on human health can be roughly divided into two categories: one is harmful gas, such as sulfur dioxide, nitrogen dioxide, carbon monoxide, carbon dioxide, ammonia, formaldehyde, ozone, benzene, benzo [ a]pyrene, etc.; secondly, the particles can be inhaled, including dust, smog, pollen and various harmful microorganism bacteria. The harmful gases and inhalable particles are enriched in indoor air, and people stay in the environment for a long time, and then the symptoms such as headache, dizziness, tiredness, somnolence, even breath disorder, arrhythmia, mental disorder and the like 'building syndrome' can occur. According to the survey statistics of international related organizations, harmful gases are found in 30% of new and reconstructed buildings worldwide and cause an increase in the morbidity and mortality of the global population. Therefore, the indoor environmental problem has become a focus of attention and discussion, which draws high attention from all countries in the world, and a great deal of manpower, material resources and financial resources are invested to control indoor air pollution, and a strict indoor air quality standard is established, and technologies for controlling indoor air pollution emerge endlessly. Such as air freshener, deodorization sundry fungus tablet, oil smoke smell-removing tablet, microwave vibration air purifier, high-efficiency ultraviolet sterilizer, etc. The products and the equipment for purifying the indoor air are effective in removing part of harmful gases or absorbable particles in theindoor air, have poor comprehensive functions and unobvious effects, and cause secondary pollution in some cases. Recently, sodium/potassium humate biochemical agents have been developed for large-area deodorization in refuse dumps.
