Hospital wastewater produced by malodorous substances, in addition to chemical raw materials, production reaction process and other production processes, more importantly, the sewage treatment stage, due to the complexity of the sewage components, the reaction between the sewage components, as well as microbial decomposition of the treatment process, in addition to volatile emission of inorganic odourous pollutants such as NH3, H2S, but also will make the sewage decomposition of organic matter converted to thiols, sulfur ethers, amines and other malodorous substances, thiols and volatile fatty amines will be volatile from the sewage, the surrounding environment caused by the impact of bad odours.
