Odor pollutants not only cause adverse psychological effects on people, but also cause varying degrees of damage to the human respiratory system, digestive system, cardiovascular and cerebrovascular system, endocrine system and nervous system. Some odor pollutants can also be oxidized in the tropospheric atmosphere. Reactions and photochemical reactions, resulting in the occurrence of acid rain and photochemical smog pollution.
◉ Odor Gas Classification
Odor gases are mainly composed of ammonia, sulfide and methanol, and can be roughly divided into five categories:
(1) Sulfur-containing compounds, such as hydrogen sulfide, mercaptans, sulfides;
(2) Chlorine-containing compounds such as amines, amides, indoles;
(3) Halogens and derivatives. Such as chlorine, halogenated hydrocarbons;
(4) Hydrocarbons, such as alkanes, alkenes, alkynes, aromatic hydrocarbons;
