In recent years, complaints about bad smells and smells in China are increasing year by year, and the proportion of the complaints about bad smells and smells in various environmental protection complaints is also increasing year by year. According to statistics of a Chinese environment-friendly reporting management platform, the ratio of the odor and the peculiar smell in the atmospheric pollution reporting problem in the whole country in 2018 is more than 40.58%, and particularly, the odor and the peculiar smell are more prominent in the midsummer. Complaints about malodorous smells in summer may account for 28.69% of complaints about air pollution. At present, the problem that the odor and peculiar smell disturb people becomes one of key contents for environmental protection supervision.
The odor and peculiar smell have wide pollution sources, and the related industries are various, and the pollutants are various. Common odor pollution sources in life mainly comprise black odor water, garbage transfer stations, garbage landfills, sewage treatment plants, chemical plants, feed factories, livestock and poultry farms, domestic lampblack and the like.

Generally, one pollution source can detect several or even ten kinds of malodorous substances, and the complexity of malodorous and odorous pollution and the difficulty of control and management are increased.
The amount of malodor perceived by humans is directly proportional to the logarithm of the malodor concentration, i.e., the malodor concentration is reduced by 90% and humans perceive the malodor concentration as reduced by only half. Therefore, the prevention and control of the odor and peculiar smell pollution are more difficult than other air pollution treatment. For controlling the odor and peculiar smell, various control technologies are developed at home and abroad, and an absorption method, an adsorption method, a combustion method, a biological method, a masking method, an ion method and the like are common.
